Evaluate the following y^2-5y+2

Aleksandr [31]

If y = 3, then you substitute 3 into wherever it says y.

So the original:
y² - 5y + 2

becomes:
3² - 5×3 + 2.

which is:
9 - 15 + 2.

9 - 15 = -6
-6 + 2 = -4.

-4 is the answer.

Two parallel lines are crossed by a transversal.

patriot [66]

Answer:

C. $m=102$

Step-by-step explanation:

We have been given an image of two parallel lines crossed by a transversal. We are asked to find the measure of m.

We can see that angle that measure 78 degrees and angle m are consecutive interior angles.

Since we know that consecutive interior angles are supplementary, so we can set an equation to find the measure of m as:

$78^{\circ}+m^{\circ}=180^{\circ}$

$78^{\circ}-78^{\circ}+m^{\circ}=180^{\circ}-78^{\circ}$

$m^{\circ}=102^{\circ}$

Therefore, the value of m is 102 and option C is the correct choice.
