Which points are on the graph of the equation - 3x + 6y + 5 = -7?

ludmilkaskok [199]

Answer:

C and E

Step-by-step explanation:

To solve this problem, let's plug in each coordinates into the equation.

$-3(-3) + 6(6) + 5 = -7$
$9 + 36 + 5 = -7$
$50 = -7$
$50 \neq -7$
A. cannot be the answer, as 50 does not equal -7.

$-3(-2) + 6(0)+5=-7$
$6+0+5=-7$
$11=-7$
$11\neq -7$
B. cannot be the answer, as 11 does not equal -7.

$-3(0) + 6(-2) + 5 = -7$
$0 - 12 + 5 = -7$
$-12 + 5 = -7$
$-7 = -7$
C. can be the answer, as -7 does equal -7.

$-3(6)+6(-3)+5=-7$
$-18-18+5=-7$
$-36+5=-7$
$-31\neq -7$
D. cannot be the answer, as -31 does not equal -7.

$-3(8) + 6(2) + 5 = -7$
$-24 + 12 + 5 = -7$
$-12 + 5 = -7$
$-7 = -7$
E. can be the answer, as -7 does equal -7.

Which statement is true about the function f(x)=-√-x

Harrizon [31]

Answer: D.The domain and range of the function are the same.

Step-by-step explanation: Given function f(x)=-√-x.

The given function is a square root function and we have minus sign in front of x inside square root.

A square root always defined for positive values or 0.

In order to get a positive number or 0 inside square root, let us solve the inequality:

$-x\geq 0$

On dividing both sides by -1, the inequality sign would get flip and we get

<h3>Domain: $x \leq 0.$ </h3>

We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.

<h3>Therefore, range would also be : $x \leq 0.$ .</h3><h3>Therefore, correct option is D option.</h3>
