Answer:

=\left(-\frac{19}{2},\:-2\right)

Step-by-step explanation:

\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-10,\:5\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:-9\right)\\\\=\left(\frac{-9-10}{2},\:\frac{-9+5}{2}\right)\\\\Simplify \\=\left(-\frac{19}{2},\:-2\right)

Match the conditional statement p→q, the converse q→p, the inverse ~p→~q, and the contrapositive ~q→~p in words.
Yuri [45]

For the text answers:

conditional - If 2 lines are supplementary then the measure of the angles sum is 180

converse - If the measure if the angle sum is 180 then the 2 lines are supplementary

inverse - If 2 lines are not supplementary then  the measure if the angle sum is not 180

contrapositive - If  the measure if the angle sum is not 180 then 2 lines are not supplementary.


answer to the picture one:

conditional - If you do all your math homework then you will do well on the test.

converse - If you do well on the test then you do all your math homework

inverse - If you do not do all your math homework then you will not do well on the test.

contrapositive - If you do not well on the test then you did not do all your math homework

statistical models predict that price p( in dollars) of a new smartphone will change according to the function p=900-4t^2. where
Gre4nikov [31]

we are given

p=900-4t^2

where

price p( in dollars) of a new smartphone

t is the number of months since January

now, we can solve for t

step-1:

Add both sides by 4t^2

p+4t^2=900-4t^2+4t^2

p+4t^2=900

step-2:

Subtract both sides by p

p+4t^2-p=900-p

4t^2=900-p

step-3:

divide both sides by 4

\frac{4t^2}{4} =\frac{900-p}{4}

t^2=\frac{900-p}{4}

t^2=225-0.25p

step-4:

Take sqrt both sides

\sqrt{t^2} =\sqrt{225-0.25p}

t=\sqrt{225-0.25p}

so, we get

t=\sqrt{225-0.25p}..............Answer
