Mathematics

Mashutka [201]3 years ago

Answer:

D

Step-by-step explanation:

There are no excluded values of x in the domain of the function.

Thus domain is - ∞ < x < ∞

The range covers the permissible values of y

These are from (- 1, 16 ) downwards to - ∞

Thus range is y ≤ 16

3x - 5y = -35 <br> please solve and show your work
scoray [572]
You use the formula y=mx+b, therefore you have to isolate the y
First you subtract 3x to both sides.
3x - 5y = -35
-3x -3x
Then it would be
-5y = -3x -35
Then you divide -5 on both sides to isolate the y
-5y = -3x -35
/-5 /-5 /-5
Two negatives cancel out and make a positive so it would be
Y = 3/5x + 7

What values of x make the two expression below equal?
nasty-shy [4]
The denominator can't equal 0.
11(x-7) \not= 0 \\ x-7 \not=0 \\ x \not= 7 \\ \\ \\ \frac{(2x+1)(x-7)}{11(x-7)}=\frac{2x+1}{11} \\ \\&#10;(2x+1)(x-7) \cdot 11= 11(x-7) \cdot (2x+1) \\&#10;11(2x+1)(x-7)=11(2x+1)(x-7) \\ \\&#10;x \in R \setminus \{7 \}

The answer is D.
