Answer:
[tex] \sqrt{24} = 4.9[/tex]
[tex] \sqrt{102} = 10.1[/tex]
positive integers = x
4.9 < x < 10.1
x = 5, 6, 7, 8, 9, 10
sum = 5 + 6 + 7 + 8 + 9 + 10
= 45

Answer:
x = -2 —> y = 4
x= 0 —> y = 1
x= 3 —> y = 1/8
Step-by-step explanation:
X= –2[tex]y = ( \frac{1}{2} ) ^{x} \\ y = ( \frac{1}{2} ) ^{ - 2} =( \frac{2}{1} ) ^{2} = {2}^{2} = 4[/tex]
X= 0[tex]y = ( \frac{1}{2} ) ^{x} \\ y = ( \frac{1}{2} ) ^{ 0} =1[/tex]
X= 3[tex]y = ( \frac{1}{2} ) ^{x} \\ y = ( \frac{1}{2} ) ^{ 3} = \frac{ {1}^{3} }{ {2}^{3} } = \frac{1}{8} [/tex]

6.6 = 3(z − 16.9) − –0.6
z =
Answer:
z = 18,9
Step-by-step explanation:
[tex]6.6 = 3(z - 16.9) - - 0.6[/tex]
[tex]6.6 = 3z - 50.7 - ( - 0.6)[/tex]
[tex]6.6 = 3z - 50.7 + 0.6[/tex]
[tex]6.6 = 3z - 50.1[/tex]
[tex]6.6 - 3z = - 50.1[/tex]
[tex] - 3z = - 50.1 - 6.6[/tex]
[tex] - 3z = - 56.7[/tex]

Answer:
3/35
Step-by-step explanation:
total bottles 7/7
4/7 are big,
7/7-4/7=3/7 remaining bottles.
4/5×3/7=12/35 are small.
you add the big bottles and small bottles
4/7+12/35=32/35
then you minus from the total which is 7/7
7/7-32/35=3/35 are tiny.

1/2(f+y)=f-5 as a sentence
Step-by-step explanation:
½(f + y) = f - 5
(f + y)/2 = f - 5
y + f = 2f - 10
y = f - 10
or
f = y + 10

Find the distance between the two points in simplest radical form (-8,-4) (0,-8).
Answer: Distance = 4√5
Concept:
Here, we need to know the concept of the distance formula.
The distance formula is the formula, which is used to find the distance between any two points.
If you are still confused, please refer to the attachment below for a clear version of the formula.
Solve:
Given information
(x₁, y₁) = (-8, -4)
(x₂, y₂) = (0, -8)
Given equation
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute values into the equation
[tex]Distance=\sqrt{(0+8)^2+(-8+4)^2}[/tex]
Simplify values in the parentheses through addition
[tex]Distance=\sqrt{(8)^2+(-4)^2}[/tex]
Simplify exponents
[tex]Distance=\sqrt{64+16}[/tex]
Simplify by addition
[tex]Distance=\sqrt{80}[/tex]
Simplify the radical value into the simplest form
[tex]Distance=4\sqrt{5}[/tex]

I need these in slope intercept form
Answer:
y = 5/2 x
Step-by-step explanation:
2m + c = 5
4m + c= 10
__________-
-2m = -5
m = 5/2
c = 0
so, the equation in slope intercept form : y = mx + c
y = 5/2 x + 0
y = 5/2 x
Answer:
y = 5/2 x
Step-by-step explanation:
2m + c = 5
4m + c= 10
__________-
-2m = -5
m = 5/2
c = 0
so, the equation in slope intercept form : y = mx + c
y = 5/2 x + 0
y = 5/2

make a the subject of the formula x²=a²-a²w²
Answer:
a = ± [tex]\sqrt{\frac{x^2}{1-w} }[/tex]
Step-by-step explanation:
Given
x² = a² - a²w ← factor out a² from each term on the right side
x² = a²(1 - w) ← divide both sides by (1 - w)
[tex]\frac{x^2}{1-w}[/tex] = a² ( take the square root of both sides )
± [tex]\sqrt{\frac{x^2}{1-w} }[/tex] = a

Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms? Explain. Sample Response: If there is a variable term and a constant on each side of the equation, then you will need to use the addition or subtraction property of equality once to isolate the variable term and once to isolate the constant. Which did you include in your response? Check all that apply. Use the addition or subtraction property of equality once to isolate the variable term. Use the addition or subtraction property of equality once to isolate the constant.
Answer:
We have to use addition or subtraction property of equality to determine the value of variable involve.
Step-by-step explanation:
Example with variable term:
3x=4-x
Add x on both sides of equation:
3x+x=4-x+x
4x=4
x=1
Example with contact involve:
5y+7=12
Subtract 7 from both sides
5x+7-7=12-7
5x=5
x=5/5
x=1
let h (x)= -x-18 find h (3)

h(3) = -(3)-18 = -21
Answer:
[tex]h(3)=-21[/tex]
Step-by-step explanation:
One is given the following:
[tex]h(x) = -x - 18[/tex]
One is asked to find the value of ([tex]h(3)[/tex]). Substitute ([tex]3[/tex]) in place of ([tex]x[/tex]) and simplify to evaluate,
[tex]h(x)=-x-18\\\\h(3)=-(3)-18\\\\h(3)=-3-18\\\\h(3)=-21[/tex]

2. Which number line is correct? Why are the others incorrect?
Answer:
the middle one is correct
Step-by-step explanation:
the first one is incorrect because the way negative numbers are ordered is incorrect it should be "-3, -2, -1"
the middle one is correct because the pattern is consistent and the order of the numbers are correct
the third one is incorrect because the pattern doesn't match "-15" isn't counting by twos 15 isn't an even number
hope I helped ❤
Explanation:
The first number line is incorrect because the -1, -2, -3 should be reversed to get -3, -2, -1. It's reversed because the negatives are a mirror image of the positive counterpart.
The second number line is correct. Each number shown is separated with a gap size of 20. This gap size stays the same throughout the number line.
The third number line is incorrect. The gap from -15 to -12 is 3 units, while the gap from -12 to -10 is 2 units. We see that the gap size isn't the same through the entire number line.
So to summarize: the gap size must be the same and the numbers must be written in the correct order.
