(B)

Step-by-step explanation:

Rewrite the equations into their standard forms. The first one can be rewritten as

$10x - 12y = -5$

and the 2nd can be rewritten as

$3x + 5y = -1$

Solving this system either by substitution or elimination, we get

$x = -\dfrac{37}{86}\:\:\text{and}\:\:y= \dfrac{25}{86}$

If you add x + y, you'll get a negative number.

Given f(x) = x^2 – 3x – 2, what is f(5)?

miskamm [114]

Answer:

$f(5)=8$

Step-by-step explanation:

Given function: $f(x)=x^2-3x-2$

To find $f(5)$ , simply input $x=5$ into the function:

$\begin{aligned}\implies f(5) & =5^2-3(5)-2\\& = 25-15-2\\& = 10-2\\& = 8\end{aligned}$

Softa [21]

ANSWER: M(-9,-4) to M’(-5,2)
If (x,y) is to (x+4,y+6)
Then (-9,-4) is to (-9+4,-4+6)
Hence (-9,-4) is to M’(-5,2)
Hopefully it’s correct

Given m∠P = 38° and m∠O = 70°, find m∠1.<br><br><br>38 72 108 142

mote1985 [20]

Answer:

Step-by-step explanation:

We know: The sum of the measures of a triangle is 180°.

Therefore we have the equation:

$m\angle P+m\angle O+m\angle 1=180^o$

We have

$m\angle P=38^o,\ m\angle O=70^o$

Substitute:

$38^o+70^o+m\angle 1=180^o$

$108^o+m\angle1=180^o$ <em>subtract 108° from both sides</em>

$m\angle1=72^o$
