Answer:

8x-y-1

Step-by-step explanation:

First remove the parentheses

5x-2y+7+3x+y-8

Add 5x and 3x

8x-2y+7+y-8

add -2y and y

8x-y+7-8

Subtract 8 from 7

Answer:

=8x-y-1

Step-by-step explanation:

So we have the expression:

(5x-2y+7)+(3x+y-8)

Combine like terms:

=(5x+3x)+(-2y+y)+(7-8)

Add:

=8x-y-1

And we're done!

In the figure below, CD bisects m∠ACB, AB=BC, m∠BEC=90°, and m∠DCE=42°. Find the measure of ∠A.
vesna_86 [32]

Answer:  ∠A= 24\textdegree

Step-by-step explanation:

Since we have given that

CD bisects m∠ACB,

⇒  m∠ACD= m∠DCB =x (say)

And, AB=BC, m∠BEC=90°, and m∠DCE=42°

So,

m∠CAD=m∠ACD

In ΔDCE,

\angle DCE+\angle CED+\angle CDE=180\textdegree\\\\(\text{Sum of anlges in triangle is }180\textdegree)\\\\42\textdegree+90\textdegree+\angle CDE=180\textdegree\\\\132\textdegree+\angle CDE=180\textdegree\\\\\angle CDE=180\textdegree-132\textdegree\\\\+\angle CDE=48\textdegree

Now, in  ΔACD,

x+x=48\textdegree\\\\2x=48\textdegree\\\\\text{( Sum of interior anlges is equal to exterior angles )}\\\\x=\frac{48}{2}\\\\x=24\textdegree

Hence , ∠A= 24\textdegree

Use the calculator to evaluate the function y = 1 *2 - 2 for the given values of x.
krok68 [10]

Answer:

when x= -4, y= 2

when x= 6, y =7

Step-by-step explanation:

We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2

first we do the exponent

y= 1/4 (16) - 2

Then the multiplication

y= 4-2

then subtraction

y=2

For the second problem, it becomes y= 1/4 (6)^2 -2   We follow the same steps

y = 1/4 (36) - 2

y= 9-2

y= 7
