Answer:
9 & 2.
Step-by-step explanation:
let x represent the unknown numbers.
x + x-7 = 11
2x = 11+7
2x = 18.
divide both sides by 2.
x = 9.
x-7 = 9-7 = 2
Answer:
The second set.
Step-by-step explanation:
Consider the first set of ordered pairs.
For an increase of 9 is the x-values the y values increases by 1.
In the case of the second set the increase in y values compared with increase in y values is different:
x = 2-0 = 2, y = 10- 0 = 10. That is 5 units of y for every unit of x.
x = 5-2 = 3, y = 13-10 = 3. That is 1 unit of y for every 1 unit of x.
Answer:
D. All the choices are correct
I think that's the right answer, if it isn't than my bad!!
Answer:
L=(8x^2+3)/x
Step-by-step explanation:
The area of a rectangle is length time width.
A=LW
In this case,
A=32x^2+12
W=4x
Solve for L
L=A/W
Substitute
L=(32x^2+12)/4x
L=(8x^2+3)/x
If x = 7 you substitute all the x in the equation by 7:
y = -2(7) + 5
y = -14 + 5
y = -9
Hope it helped,
Happy homework/ study/ exam!
