f(x)= 2/3x +3; Find when f(x)=-5
Hi ;-)
f(x) = ²/₃x + 3 ∧ f(x) = -5
²/₃x + 3 = -5
²/₃x = -5 - 3
²/₃x = -8 / * ³/₂
x = -12
Solve for x: two thirds(x − 2) = 4x
Answer:
-2/5 =x
Step-by-step explanation:
2/3 ( x-2) = 4x
Multiply each side by 3/2
3/2 * 2/3 (x-2) = 3/2 *4x
x-2 = 6x
Subtract x from each side
x-2-x = 6x-x
-2 = 5x
Divide each side by 5
-2/5 = 5x/5
-2/5 =x
x=− 2/5=−0.4 is the answer please mark brainliest

Refer to the attached diagram for further a visual explanation. As per the given information, segments (AB) and (AD) are congruent. Moreover, segments (AC) and (AE) are also congreunt. One is also given that angles (<BAD) and (<EAC) are congruent. However, in order to prove the triangles (ABC) and (ADE) are congruent (using side-angle-side) congruence theorem, one needs to show that angles (<BAC) and (<DAE) are congruent. An easy way to do so is to write out angles (<BAC) and (<DAE) as the sum of two smaller angles:
<BAC = <BAD + <DAC
<DAE = <DAC + <EAC
Both angles share angle (DAC) in common, since angles (<EAC) and (BAD) are congruent, angles (<BAC) and (<DAE) must also be congruent.
Therefore triangles (ABC) and (ADE) are congruent by side-angle-side, thus sides (BC) and (DE) must also be congruent.
In summary:
AB = AD Given
AC = AE Given
<BAD = <EAC Given
<DAC = <DAC Reflexive
<BAC = <BAD + <DAC Parts-Whole Postulate
<DAE = <EAC + < DAC Parts-Whole Postulate
<BAC = <DAE Transitivity
ABC = ADE Side-Angle-Side
BC = DE Corresponding parts of congruent triangles are congruent
Can someone please help me use a protractor on this question since I don’t have one?
Answer:
If you don't have a protractor handy, you can determine the size of an angle using the basic geometric principles of triangles. You'll need a scientific calculator to solve the equations. Most smartphones are equipped with them, but you can also download a free app or access a free calculator online.

Evaluate the expression when y = -2
- 8y2
I believe this is the expression:
[tex] \displaystyle \large \boxed{ - 8 {y}^{2} }[/tex]
Since we want to evaluate it when y = -2, simply substitute y = -2 in the expression.
[tex] \displaystyle \large{ - 8 {( - 2)}^{2} }[/tex]
Any negative number squared will result in positive, refer below:
[tex] \displaystyle \large{ {( - a)}^{2} = {a}^{2} } \\ \displaystyle \large{ {( - 2)}^{2} = {2}^{2} } \longrightarrow \boxed{4} \\ [/tex]
Hence,
[tex] \displaystyle \large{ - 8(4) = - 8 \times 4} \\ \displaystyle \large \boxed{ -32}[/tex]
Answer:
-32
Step-by-step explanation:
Replace the variable y with -2 in the expression giving -8(-2)^2
Then, square -2 giving us (positive) 4
Lastly, multiply -8 with 4 and get -32 as our answer
(Hopefully this helped you! Feel free to ask again if you need more help. Tell me if the solution is unclear to you)

If Gabby wants to buy a t-shirt for $35.99 but she has a discount for 10% off, how much is her final cost?
Answer:
It's $32.39.
Step-by-step explanation:
35.99 - 35.99*10% =
=35.99 - 35.99*0.1
=35.99 - 3.599
=32.391
32.391 is close to 32.39 so we will round it to that number.

The required sum of the arithmetic progression is 441.
Arithmetic progression is the series of numbers that have common differences between adjacent values
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
45 + 46 + 47 . . . . . . 54
About sequence is an arithmetic sequence with,
First term a = 45
common difference d = 1
last term l = 54
Number of terms = 45 - 54 = 9
The required sum of the arithmetic progression can be given as,
s = n / 2 * ( 2a + (n - 1) d )
s = 9 / 2 * (2 * 45 + 8 * 1)
s = 9 / 2 * (98)
s = 9 *49
s = 441
Thus, the required sum of the arithmetic progression is 441.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at a rate of 45 miles per hour. The westbound train travels at a rate of 55 miles per hour. How long will it take for the two trains to be 280 miles apart
Answer: 2.8 hours
Step-by-step explanation:
Train A: time= t, v=45mi/hr, d= d
Train B: time t, v= 55mi/hr, d=280-d
Distance = v times t (d=vt)
t = d/v (time for both trains is the same, so t=t)
Train A: t=d/45
Train B: t=(280-d)/55
d/45 = (280-d)/55 (cross multiplication)
55d = 15400-45d
55d+45d = 15400
100d = 15400
d = 154 miles (280miles - 154miles = 126 miles)
Train A travel 154 mi and train B travel 126 mi
Train A travel 154 miles in 2.8 hrs.
Train B travel 126 miles in 2.8 hrs.
154 miles at a rate of 55mi/h = 2.8 hours and
126 miles at a rate of 45mi/h = 2.8 hr.

11. Write y = 2x² +12x+14 in vertex form.
Please show work if possible so I know how to do it
Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
y = 2x² + 1 2x + 14
Move the constant (14) to the left side
y - 14 = 2x² + 12x
Now factor out 'a' , the coefficient of x² term
y - 14= 2(x² + 6x)
Divide the coefficient of 'x' by 2 ⇒ 6/2 = 3
Find the square of '3' and add it to x² + 6x ⇒ x² + 6x + 9
Multiply the square of 3 and add it to y - 14; 9*2 = 18
y- 14 = 2(x² + 6x + 9)
y - 14 + 18 = 2(x² + 6x + 9)
y + 4 = 2(x² + 6x +9)
y + 4 = 2(x + 3)²
y = 2(x + 3)² - 4

ATTENDING TO PRECISION The diagram shows an insect called a walking stick Use the ruler to estimate the length of the abdomen and the length of the thorax to the nearest inch. How much longer is the walking stick's abdomen than its thorax? How many times longer is its abdomen than its thorax?
Estimation and precision are used when the actual value cannot be easily determined or calculated.
The length of the abdomen is [tex]2\frac 14[/tex] inchesThe length of the thorax is [tex]1\frac 34[/tex] inchesThe abdomen is longer than the thorax [tex]1\frac 27[/tex] timesGiven that, the length is to be measured to the nearest [tex]\frac 14\ inch[/tex], we have the following observations
The length of the abdomen starts at the 0 mark and ends after the 2-mark. The length ends before [tex]2\frac{1}{2}[/tex]. So, the length of the abdomen can be estimated to [tex]2\frac{1}{4}[/tex] --- to the nearest [tex]\frac{1}{4}[/tex].Similarly, the length of the thorax starts at the [tex]2\frac{1}{4}[/tex] mark and ends before [tex]4\frac{1}{4}[/tex]. The end of the thorax length can be estimated to: [tex]4[/tex] --- to the nearest [tex]\frac{1}{4}[/tex].So, we have:
[tex]L_1 = 2\frac 14[/tex] --- the length of the abdomen
[tex]L_2 = 4 - 2\frac 14[/tex]
Express as improper fraction
[tex]L_2 = 4 - \frac{9}{4}[/tex]
Take LCM
[tex]L_2 = \frac{16 - 9}{4}[/tex]
[tex]L_2 = \frac{7}{4}[/tex]
Express as proper fraction
[tex]L_2 = 1\frac{3}{4}[/tex] --- the length of the thorax
The number of times (n) the abdomen is longer than the thorax is calculated as follows:
[tex]n = L_1 \div L_2[/tex]
So, we have:
[tex]n = 2\frac 14 \div 1\frac 34[/tex]
Express as improper fractions
[tex]n = \frac 94 \div \frac 74[/tex]
Rewrite as:
[tex]n = \frac 94 \times \frac 47[/tex]
[tex]n = \frac 97[/tex]
Express as proper fractions
[tex]n = 1\frac 27[/tex]
Hence, the abdomen is [tex]1\frac 27[/tex] times longer than the thorax

The straight line ax+by=1passes through the points (1,4)and (3,1).Find the values of a and b?
Answer:
a= 3/11
b = 2/11
Step-by-step explanation:
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
The value of a and b are 3/11 and 2/11 respectively.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given that the straight line ax+by=1 passes through the points (1,4)and (3,1).
Thus, the equation of the straight line passing through the point ( 3,1 )
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
Thus, the equation of the straight line passing through the point(1,4)
a(1) + b(4) = 1
a + 4b = 1
Now substitute the value of b;
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
Then b = 1-3(3/11)
b= 2/11
Hence, the value of a and b are 3/11 and 2/11 respectively.

8. If angle CBD = angle DBE find m angle A
Answer:
m∠A = 65°
Step-by-step explanation:
Because ∠CBD is congruent to ∠DBE, we can set the degree values equal to each other.
So
CBD has x + 10, DBE has 60. So:
x + 10 = 60
Subtract 10 from both sides.
x = 50
Check:
50 + 10 = 60
60 = 60
m∠A = (x + 5)° = (60 + 5)° = 65°
The measure of m<A if angle CBD = angle DBE is 55°
The point where two lines meet is known as an angle.
We are given the following from the diagram:
m<CBD = x +10
m<DBE = 60degrees
Since angle CBD = angle DBE, then:
x + 10 = 60
x = 60 - 10
x = 50degrees
Get the angle A.
From the diagram, angle A = (x+5)°
m<A = 50 + 5
m<A = 55°
Hence the measure of m<A is 55°
