-3
Explanation:
If f(x)=f(-1) then you just fill in -1 where x is.
2*-1-1
-2-1

6 - 15/40 = 0.375 = 37.5%
When looking to convert a decimal to a percent you move the decimal over two places so, 0.375 becomes 37.5
8 - 70*1.2 = 80
You see 100% is equal to 1.00 when multiplying/dividing. So 1.2 = 120%
10 - 48*0.25 = 12 and 12+48 = 60 So, 60.
Here, we use 0.25 because 100% - 75% = 25% or... 1.0 - 0.75 = 0.25
For 11, we start by plugging 1 in, getting 2(1)^2+1-5=-2=y
Plugging 1+m instead, we get 2(1+m)^2+1+m-5=2(1+2m+m^2)+1+m-5
= 2+4m+2m^2+1+m-5= 2m^2+5m-2. We have to find the difference between that and -2, so 2m^2+5m-2 -(-2)=2m^2+5m
Differentiating 12, we use the Power Rule to get -6x^2+14, and plugging x=1 into it, we get -6(1)^2+14=-6+14=18
Answer:
The measure of angle f is 61°
Step-by-step explanation:
A straight line is 180° meaning;
180 - 98 = 82
82 is the angle measure of the unlabeled angle.
All triangles angles add up to 180° meaning;
37 + 82 = 119
180 - 119 = 61°
Answer:
x = -3
Step-by-step explanation:
15 - 2x = -7x
add 2x
15 = -5x
divide by -5
-3 = x
