Hey there!
Let's combine like terms!
First, let's write them together, like so:
-2.8d+2.8d-2.8d+2.8d-1.33+3.4-1.33
And now we can see that -2.8d and 2.8d cancel out:
-2.8d+2.8d-1.33+3.4-1.33
And they cancel out again:
-1.3+3.4-1.33
Now all we have to do is add the numbers together:
0.77
Hope it helps!
Answer:
-6+x
Step-by-step explanation:
Let the number=n
x-n=6
-n=6-x
n=-6+x
H = -16t² + 64t + 80 (:16)
H = -t² + 4t + 5
/\ = b²-4ac
/\ = 4²-4.(-1).5
/\ = 16+20
/\ = 36
Yv = -/\ / 4a
Yv = -36/4.(-1)
Yv = -36/-4
Yv = 9
F(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4
Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4
Answer: -4
Answer:
Slope= -5
y-intercept=8
Step-by-step explanation:
In the formula y=mx+b
The m is the slope and the b is the y-intercept.
