Choose exactly two answers that are correct.
A.y-7= -3/4(x+5)
B.y-5= -4/3(x+7)
C.y+4= -3/4(x+1)
D.y-1= -4/3(x+4)
Answer:
x = 1/8
Step-by-step explanation:
Given:
Multiplying by 4x throughout, we will have:
⇒ 8x + 9 = 80x
⇒ 9 = 72x
Dividing by 72,
⇒ x =
⇒ x =
Substitute x = 1/8 in the given equation and it will give us 20. That means the value of 'x' identified is correct.
So, x = is the required answer.
Answer:
x=7
Step-by-step explanation:
The line y = 8 is a horizontal line through 8 on the y-axis. A perpendicular line will be a line vertically through it of the form x = a where a is the x-coordinate.
Since the line crosses through (7,6) then the form of the line is x = 7.
35 = - 5/9x
mutiply both sides by -9/5
35*-9/5= -5/9x*-9/5
Cross out 5 and 35, divide by 5.
35/5= 7
-5/5= -1
Cross out the 5 and 5 , divide by 5.
Cross out the 9 and 9, divide by 9.
then becomes 1*1*x= x
7*-9= -63
Answer : x= -63
