How do you solve this: 2x+4+2=7x-6-3?
The answer you are looking for is x=3.
Solution/Explanation:
First, writing out the equation,
2x+4+2=7x-6-3.
Next, simplifying the equation just a little bit more, with the four numbers that do not include the variable "x" at all,
2x+6=7x-9.
Now, subtracting 7x from both sides of the equation,
2x+6-7x=7x-9-7x.
Regrouping the positions of the terms, using the Associative Property,
2x-7x+6=7x-7x-9.
Simplifying, and also, canceling out the 7x, since 7x-7x=0.
2x-7x+6=0-9, or 2x-7x+6=-9.
Simplifying "2x-7x," which is -5x,
-5x+6=-9.
Now, subtracting 6 from both sides,
-5x+6-6=-9-6.
Canceling out the "6," since 6-6=0,
-5x=-9-6.
Solving for "-9-6," which is "-15,"
-5x=-15.
Finally, dividing both sides by "-5,"
-5x/-5=-15/-5.
Simplifying "-5x/-5=-15/-5,"
-5x/-5=x.
And, also, -15/-5=3.
This eventually leads to x=3.
So, therefore, the final answer is x=3.
I hope that this has helped answer your question. Good day to you.
Answer:
The answer is x=3.
Step-by-step explanation:
2x+6=7x-9
-5x=-15
x=3

For the following system of equations, determine how many solutions there are. y = 5(x − 4) and 4x + 12 = −y
Answer:
It has two solutions
Step-by-step explanation:
[tex]y = 5(x - 4)[/tex]
substitute for y in second equation:
[tex]4x + 12 = - y \\ 4x + 12 = - \{5(x - 4) \} \\ 4x + 12 = - 5x + 20 \\ 9x = 8 \\ x = \frac{8}{9} [/tex]
then for y:
[tex]y = 5(x - 4) \\ y = 5( \frac{8}{9} - 4) \\ \\ y = 5( - \frac{28}{9} ) \\ \\ y = - \frac{140}{9} [/tex]
3. A sea gull was flying 4 feet above sea level when a fish below it jumped one foot out of the water. How far apart were the seagull and the (unlucky) fish?
Answer: 3ft difference
Step-by-step explanation:
Seagull = +4ft
Fish = +1ft (since it jumped 1ft above sea level)
4-1 = 3ft difference
solve for x, need help asap!
Let's solve for x using trigonometric relation ( Cos )
we know,
[tex] \cos(30 \degree) = \dfrac{base}{hypotenuse} = \dfrac{ \sqrt{3} }{2} [/tex]
now
[tex] \dfrac{x}{8} = \dfrac{ \sqrt{3} }{2} [/tex]
[tex]x = 8 \times \dfrac{ \sqrt{3} }{2} [/tex]
[tex]x = 4 \sqrt{3} [/tex]
hence, the value of x is [tex] 4 \sqrt{3} [/tex]

A wall is 4200 sq ft.
A gallon of paint covers 600 sq ft.
Complete the conversion factor: 1 gallon / ? sq ft
Answer:
1 gallon = 600 sq ft. So you will need 7 gallons to cover the whole wall
Step-by-step explanation:
4200 ÷ 600 = 7
Answer:
7
Step-by-step explanation:
Divide the total wall space by the amount in 1 gallon: 4200/600= 7
So you would need 7 gallons to paint the whole wall.

By substitution method
5x - 3y =1

[tex]5x - 3y = 1 \\ 5x = 1 + 3y \\ x = \frac{1 + 3y}{5} [/tex]
______o____o_____
[tex]3x + 2y = 1 \\ 3( \frac{1 + 3y}{5} ) + 2y = 1 \\ \frac{3 + 9y}{5} + 2y = 1 \\ \frac{3 +9y + 10y}{5} = 1 \\ \frac{3 + 19y}{5} = 1 \\ 3 + 19y = (1)(5) \\ 3 + 19y = 5 \\ 19y = 5 - 3 \\ 19y = 2 \\ y = \frac{2}{19} [/tex]
______o_____o____

At the zoo the polar bears are fed 0.1 bucket of fish a day.
The penguins are fed 0.83 that amount. How much of a
bucket are the penguins fed?
Answer:
0.083
Step-by-step explanation:
0.1 x 0.83 = 0.083
There are 0.083 bucket are the penguins fed.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
At the zoo the polar bears are fed 0.1 bucket of fish a day.
And, The penguins are fed 0.83 that amount.
Now,
Since, At the zoo the polar bears are fed 0.1 bucket of fish a day.
And, The penguins are fed 0.83 that amount.
Hence, The bucket are the penguins fed is,
⇒ 0.83 × 0.1
⇒ 0.083

Step-by-step explanation:
To solve the left inequality for x, subtract 1/2 from both sides:
x ≤ -3 -1/2
x ≤ -7/2

Answer:
Linear Function
Step-by-step explanation:
This is a linear function. A linear function is a function with the degree of 1, where the line increases continuously the whole graph. The growth of the graph is constant, making a straight line. This function is written in slope-intercept form, f(x) = mx+b. Where m is the slope and b is the y-intercept. The function will have 1 solution.

(A) What are the next three numbers in this sequence?
(B) Using n to represent the position of a number in this sequence, write an expression that allows you to calculate the nth number.
(C) use your expression to find the 100th number in this sequence
Step-by-step explanation:
(A) 42,40
(B) T(n) = 50 + (n-1)(-2)
= 50+2-2n
= 52-2n

Describe how many zeros this equation will have, and where they are.
(1 Point)
f (x) = -2x2 – 5x – 2
Answer:
Let y=x
2
−5x+6, when we substitute different values of x in the equation y=x
2
−5x+6 then value of y changes accordingly.
When x=0 then
y=(0)
2
−(5×0)+6=0−0+6=6
The point is (0,6)
When x=2 then
y=(2)
2
−(5×2)+6=4−10+6=10−10=0
The point is (2,0)
When x=3 then
y=(3)
2
−(5×3)+6=9−15+6=15−15=0
The point is (3,0)
Therefore, the coordinates are (0,6), (2,0) and (3,0) and the graph of the quadratic equation y=x
2
−5x+6 is as shown above.
Hence, from above graph, we get that x=2 or x=3.
