Answer:
.69, but you can round it to .70 because of the 9
Step-by-step explanation:
70%
The answer is x= 9 and -3
You must fine 2 number that multiply to equal -27 and add to equal -6
(x-9) (x+3)
Then equal the parts of the binomial to zero
x - 9 = 0
x + 3 = 0
You must get x by its self.
When you do so, you'll have the answer as -3 and 9
Answer:
y= -2x-22.
Step-by-step explanation:
1) the slope-interception common form is y=s*x+i, where 's' and 'i' are the slope and interception, unknown numbers;
2) if x₁= -3; y₁= -16, and s=-2, then the equation of the required line can be written in the point-interception form y-y₁=s(x-x₁); ⇔ y+16= -2(x+3);
3) the required equation in slope-interception form is:
y+16= -2x-6; ⇒ y= -2x-22.
