Multiply the equation 2x+7y=-1 by -2
add to othe equaiton
4x-3y=-19
<u>-4x-14y=2 +</u>
0x-17y=-17
-17y=-17
divide both sides by -17
y=1
sub back
2x+7y=-1
2x+7(1)=-1
2x+7=-1
minus 7 from both sides
2x=-8
divide both sides by 2
x=-4
x=-4
y=1
(x,y) is normal form
(-4,1) is answer
Answer:
Notice on the graph y = sin x, the graph passes through the origin (0,0). Then the graph crosses the x-axis at (p,0). When we make c positive, we move the graph to the left c units
Step-by-step explanation:
Answer:
Option d is correct.
Step-by-step explanation:
The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.
Now, the given function is

Differentiating with respect to x on both sides we get,

Again, differentiating with respect to x on both sides we get,

So, the condition for point of inflection at point c is
k''(c) = 0 = - sin c + 2 sin c cos c
⇒ sin c(2cos c - 1) = 0
⇒ sin c = 0 or 
⇒ c = 0 or
Therefore, option d is correct. (Answer)
i really don't understand what you are trying to say but if it was a math problem it would be -1.
#10) The original graph has x intercept 0 and y intercept 0. The new graph has x intercept 3 and y intercept -3
So x went up 3 and y went down 3. The answer is H.
#11) Plug in x = 0 and solve. The answer is 48, C.
#12) Use a graphing calculator or online calculator. I got r = 0.778
#13) The only one that is shaded correctly is H.
