F(x) = 8x+7 If f(x)=31 find x
Answer: x = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
31 = 8x + 7
Step 1: Flip the equation.
8x + 7 = 31
Step 2: Subtract 7 from both sides.
8x + 7 − 7 = 31 − 7
8x = 24
Step 3: Divide both sides by 8.
8x /8 = 24 /8
x = 3
Answer:
x = 3

Answer:
b.) y = 2x ^ 2 + x - 6

now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :
[tex]y = mx + c[/tex][tex]11 = \bigg(\dfrac{5}{ 3} \times 6 \bigg) + c[/tex][tex]11 = (5 \times 2) + c[/tex][tex]11 = 10 + c[/tex][tex]c = 11 - 10[/tex][tex]c = 1[/tex]value of y - intercept (c) = 1, so our equation will be :

Answer:
40
Step-by-step explanation:

Answer 15 please algebra one
Answer:
a
Step-by-step explanation:
To obtain the inverse, rearrange the relation making x the subject
y = x² + 4 ( subtract 4 from both sides )
y - 4 = x² , or
x² = y - 4 ( take square root of both sides )
x = ± [tex]\sqrt{y-4}[/tex]
Change y into terms of x with x = [tex]f^{-1}[/tex] (x) , that is
[tex]f^{-1}[/tex] (x) = ± [tex]\sqrt{x-4}[/tex] → a

sketch the graph of the equation 3y+4x=2
Simplifying
3y + 4x = 2
Reorder the terms:
4x + 3y = 2
Solving
4x + 3y = 2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
4x + 3y + -3y = 2 + -3y
Combine like terms: 3y + -3y = 0
4x + 0 = 2 + -3y
4x = 2 + -3y
Divide each side by '4'.
x = 0.5 + -0.75y
Simplifying
x = 0.5 + -0.75y
The line connecting two coordinates (0,66) and (0.5,0) show below.
What is Mathematical equation ?
By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.
Here, the given equation is :
3y + 4x = 2
now, to sketch the equation in graph we need to find the two coordinate first,
Let, x= 0 then y will be :
3y+4x=2
3y = 2
y = 2/3 = 0.66
that is first coordinate is (0,66)
Now, for y = 0 , x will be :
3y+4x=2
4x = 2
x = 0.5
that is second coordinate will be (0.5 , 0)
Now, draw the line connecting these two points show below.

A square piece of cheese covers 10 square inches of a plate. What is the approximate length of one side of the piece of cheese?
Answer:
Step-by-step explanation:
If its a square all the sides are equal so therefor if it took up ten inches of the plate the length is 10 by 10 so 100 because the equation for length is base times height.

Describe the transformation in g (x) = (-5/8x) as it relates to the graph of the parent function.
Answer:
reflection over x axis then horizontal stretch by factor of 8/5
Step-by-step explanation:
f(x)=x
h(x) = -f(x) ... reflection over x axis (x,y) -> (x,-y)
-f(x) -> g(x) = (-5/8x) ...0 < |5/8| <1 ... horizontal stretch (x,-y) -> (x / (5/8) , -y)

The sum of three consecutive odd integers is 459. What are the integers? (show your work please)
Answer:
151+153+155
Step-by-step explanation:
First you divide 459/3. That equals 153. Now you need 3 integers that add to 459. The first integer is 153 and now you subtract and add equal parts from it to get your other two. You subtract 153 by two and get 151. Then you add 153 by 2 and get 155.

Answer:
26.4 million
Step-by-step explanation:
You multiply the previous summer concert tour attendance by 0.92. In 1988, the attendance was 31 million. 31.1 × 0.92 = 28.6. The attendance in 1989 is 28.6 million. Repeat the step of multiplying by 0.92 to find the attendance in 1990. 28.6 × 0.92 = 26.36 million. Round your answer to the nearest tenth of a million will get you 26.4 million.
