Two complementary angles are in the ratio of 1:5. find the measure of the larger angle?
Luden [163]
First you set up an equation using a variable:
x + 5x = 90° (complementary angles = 90°)
6x = 90
x = 15 (also the measure of the smaller angle)

now plug in x to find the larger angle:
5(15) = 75°

If f(x) = (x + 9 and g(x) = --6, which describes the range of (f + g)(x)?
S_A_V [24]

Given:

Consider the below figure attached with this question.

To find:

The value of (f+g)(x).

Solution:

The given functions are:

f(x)=|x|+9

g(x)=-6

Now,

(f+g)(x)=f(x)+g(x)

(f+g)(x)=|x|+9+(-6)

(f+g)(x)=|x|+9-6

(f+g)(x)=|x|+3

We know that,

|x|\geq 0

Adding 3 on both sides, we get

|x|+3\geq 0+3

(f+g)(x)\geq 3

So, (f+g)(x)\geq 3 for all values of x.

Hence, the correct option is A.

If R is the midpoint of QS, QR= 8x-51 and RS = 3x-6, find QS.
sashaice [31]

QS would be 42. So the way i did it was I:

8x-51=3x-6

x=9

Plugged into both equations of QR and RS to then get the answer of 42
