Question 246357: What is the slope of any line parallel to the line 9x + 4y = 7 ? since 4y=-9x+7 i think its -9/4 but iam not even sure how i got that im so lost please explain it to me thanks …
SOLUTION: What is the slope of any line parallel to the line 9x
Here's the secret to this. y=mx+b "m" is the slope of the line. So we need to put 9x + 4y = 7 in the y=mx+b form. 9x + 4y = 7 Subtract 9x from both sides to give us: 4y = -9x + 7 Now divide both …
What are all the possible rational zeros for f(x)=2x^4-9x^2+7?
2016年11月5日 · The rational roots are x = +-1. Let a represent x^2, thus f(x)=2x^4-9x^2+7 can be rewritten as 2a^2 - 9a + 7. This is simply a matter of factoring now, remember, to find the …
SOLUTION: If F(x)=ax^2 +bx+c and F(x+5)=x^2+9x-7, find the …
2) You also are given the second piece of information: F(x+5) = x^2 + 9x - 7. To get F(1), you need to take x = -4 in the last identity, and then you will get a + b + c = F(1) = F(-4 + 5) = (-4)^2 …
