Answer:

x=25

Step-by-step explanation:

Given Equation:

4x-3(x+5)=10

Solving the equation for 'x'

4x-3(x)-3(5)=10\\\\4x-3x-15=10

Solving the like terms:

x-15=10

Adding '15' both sides:

x-15+15=10+15\\\\x=10+15\\\\x=25

The solution of the equation is: x=25

Is quadrilateral UVWX a parallelogram? Why or why not?
Neko [114]

Answer:

C

Step-by-step explanation:

Slope of UV = 0 = Slope of XW

So UV is parallel to XW.

Slope of UX = [6-(-4)]/[-7-(-3)] = -5/2

Slope of VW = [6-(-4)]/(0-4) = -5/2

Slope of UX = Slope of VW i.e. UX is parallel to VW.

It is a parallelogram because opposite sides are parallel.

What is the graph of the function f(x) = the quantity of x squared plus 4 x minus 12, all over x plus 6?
LenaWriter [7]
X^2 + 4x -12 = (x+6)(x-2)

so 
  (x+6)(x-2)
---------------- = x - 2
     x + 6

f(x) = x -2

answer is B.

because
if x = -6
then y = -6 - 2 = -8

(-6,-8) is the order pair

Olivia scored 82 points on the first mathematics test of the year. On the second mathematics test, she scored 78 points. What is
Kryger [21]

The percent of change in the number of points she scored between the first and second tests  = 4.878 %

<h3>What is percentage decrease?</h3>

If the data is decreasing,

Decrease = Original Number - New Number.

Then: divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100.

Given that:

The score of first Math test = 82

The score of second Math test = 78

Changes occurs in marks by=78-82

                                               =-4

So, there is decrease in marks.

We have to find the decrease percentage:

Decrease%= \frac{change \;in \;value}{Original\; value} *100

                   = \frac{4}{82} *100

                   = 0.04878 * 100

                  = 4.878 %

There is 4.88% decrease in Olivia's score.
