Answer:
f(x) = -5/9 x + 5 1/9
Step-by-step explanation:
f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)
f(x) = mx + b
m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9
for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9
f(x) = -5/9 x + 5 1/9
check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9

I think the answer is 5.
y = kx is the equation for direct proportionality. I’m guessing your “q” is the “y”, because 35 is easily divisible by 7.
35 = 7x
x = 5
Answer:
x= 2
Step-by-step explanation:
To solve this problem we first observe the Pythagoras equation. If a=x and b = 7 are the lengths of the legs of a right triangle and c= is the length of the hypotenuse, then<u> the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. </u>
This relationship is represented by the formula:
a*a + b*b = c*c
+ =
=> x=
