a: 2
b: 5
c 3
d: 4
I think the ans is 2
Answer:
y = 7 and x =3
Step-by-step explanation:
use elimination method
so we gonna eliminate y first
9x = 1 - 4y
-7x = -7 + 4y
7| 9x = 1 - 4y
9| -7x = -7 + 4y
63x = 7 - 28y
-63x = -63 + 36y
add eqtn 1 to eqtn2
you will get
0 = -56 + 8y
56 = -56 + 56 + 8y
56 = 8y
56÷8 = 8y÷ 8
7 = y
also eliminate x as we have done wth y
4| 9x = 1 - 4y
4| -7x = -7 + 4y
36x = 4 - 16y
-28x = -28 + 16y
add the two equations
u will get
8x = -24 + 0
8x = -24
8x÷8 = 24÷ 8
x = 3
BDE are the correct options
0.98 . Z z. ...... z .. .
Hey!
-------------------------------------------------
Point Slope Form: y - 7 = -5/2(x + 4)
Slope-intercept Form: y = mx + b
m = slope
b = y-intercept
We can automatically eliminate Option A and B because they are both written in point slope form when the questions asks for slope-intercept form.
We can also eliminate option C because the slope in the equation doesn't match the slope in the equation above.
-------------------------------------------------
Answer:
y = -5/2x - 3
