Answer:
7 C
Step-by-step explanation:
We want to find the y value for an x value of -9
The y value for the x value of -9 is 7
Answer:
x= -7 x = -4
Step-by-step explanation:
x^2 + 11x + 28 = 0
What two numbers multiply to 28 and add to 11
7*4 = 28
7+4 =11
(x+7) (x+4) =0
Using the zero product property
x+7 =0 x+4 =0
x= -7 x = -4
You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14
Answer:
K= -3
Step-by-step explanation:
-3k+6=15
-6 -6
-3k=9
/-3 /-3
k=-3
subtract 6 from both sides.
divide each side by -3 to get K alone
-3 is your answer.
