Find the inverse of y=7x-10. Is the inverse a function?
Answers
Answer: (x) =
Step-by-step explanation:
To find the inverse , all we need do is to make x the subject of the formula.
y = 7x - 10
Add 10 to both sides
y + 10 = 7x
divide both sides by 7
Therefore:
x = y + 10 / 7 , that is
(x) =
Answer:
Step-by-step explanation:
y=7x-10 calculate x : 7x-10 =y
7x = y+10
x = 1/7 y +10/7
the inverse of y=7x-10 is ; y = 1/7 x +10/7

Answer:
The correct answer is B. x ≈ 4.5, y = 5, z = 9
Step-by-step explanation:
1. We will use the Pythagorean theorem for solving for x, this way:
x² = 6² - 4²
x² = 36 - 16
x² = 20
x = √20
x = 2 √5 = 4.47 ≈ 4.5
2. For solving for y, we will do it this way:
There are only two possible options: y = 5, included in answer B or y = 9 as it is defined on answer C.
If we review it carefully, we will realize that y = 9 is not accurate because as we can see in the graph y + 4 = z and in this specific case, 9 + 4 ≠ 5 but it's true that 5 + 4 = 9.
Because of this reason, the correct answer is B. x ≈ 4.5, y = 5, z = 9

y - 5 = 2/3 ( x + 3)
That's your answer.
Final answer:
The equation of a line that passes through the point (5, -3) with a slope of 2/3, when expressed in point-slope form, is y + 3 = 2/3 * (x - 5).
Explanation:
In Mathematics, the equation of a line can be given in multiple forms, one of those is the point-slope form. The generic form of this equation is y - y1 = m(x - x1), where (x1, y1) are the coordinates of any point on the line and m represents the slope of the line.
Given the slope m = 2/3 and the point on the line (5, -3), the equation is y - (-3) = 2/3 * (x - 5). After simplifying, we have: y + 3 = 2/3 * (x - 5) as the equation of the line.
