How to solve mp-5p when m=-4 and p=2

Answers

Answer 1

Answer: You can substitute in the values. So m=-4 so put that in instead of m. And p=2 so put that in instead of p.
The problem is then (-4)(2)-5(2). Simplify to -8-10 And your final answer is -18. Wasnt aware you could edit these after you made them haha. I did correct my math in my comments riaght after the post. Sorry about that guys ^.^

Answer 2

Answer: so everyone knows, xy means x times y, not the digits themselves

so mp-5p
subsitute -4 for m and 2 for p
(-4)(2)-[(5)(2)]
-8-[10]
-18

According to the given information, quadrilateral RECT is a rectangle. By the definition of a rectangle, all four angles measure 90°. Segment ER is parallel to segment CT and ______________ by the Converse of the Same-Side Interior Angles Theorem. Quadrilateral RECT is then a parallelogram by definition of a parallelogram. Now, construct diagonals ET and CR. Because RECT is a parallelogram, opposite sides are congruent. Therefore, one can say that segment ER is congruent to segment CT. Segment TR is congruent to itself by the Reflexive Property of Equality. The Side-Angle-Side (SAS) Theorem says triangle ERT is congruent to triangle CTR. And because corresponding parts of congruent triangles are congruent (CPCTC), diagonals ET and CR are congruent.

What is the correct answer ? Please explain !

Answer:

The correct answer is B. 10x - 12y

Step-by-step explanation:

To find this, we focus on just the like terms. So we break it down by the variable each time.

5x + 5x = 10x

-6y + -6y = -12y

z + -z = 0

So we put those answers all together to get 10 - 12y + 0 or just 10x - 12y

What is the area of this trapezoid?A) 108 in²
B) 139.5 in²
C) 166 in²
D) 171 in²

Answers

Answer:

B)139.5

Step-by-step explanation:

Right-angled triangle formula A=ab/2 so find the area of both triangles left side: 2*9/2=9 right side 5*9/2= now find the area of the rectangle 9*12= add all them together 9+22.5+108=139.5

a hang glider flew to an altitude of 10,000 feet. fifteen minutes later, its altitude was 7,000 feet. what was the average change in elevation per minute?

Answers

you can use slope formula
think of it as a graph initially you start at point (0,10,000)
then you move to (15 , 7,000)
10,000 -7,000 =3,000
15 - 0 = 15
so 3,000/15 is...
200 ft per minute
since you are moving down it is a negative slope -200ft per min

10. The equation t 0.07c represents the tax, t, based on the cost, c, of an item. Which part of the equation represents the constant of proportionality? Ot 0.07

Answers

The constant of proportionality stays the same no matter what values the variables take, so in our example independently of the cost of the item (and of the tax value, which is dependent on the cost value).

Here the only value that does not change is the 0.007, the rate! - this is the correct answer.
