Answer:

25xy + 35x

Step-by-step explanation:

Expand by distributing term.

5x \times 5y + 5x \times 7

Simplify 5x × 5y to 25xy.

25xy + 5x  \times 7

Simplify 5x × 7 to 35x.

25xy + 35x

Hence, the answer is 25xy + 35x.

If EF=2x-12, FG= 3x-15, and EG=23, find values of x, EF, and FG
velikii [3]

we have that


*-------------------------*--------------------------------*

E                            F                                     G


EF=2x-12

FG= 3x-15

EG=23


we know that


EF + FG = EG


so

[2x - 12] + [3x - 15] = 23 simplify

5x - 27 = 23 add 27 to both sides

5x = 50 divide both sides by 5

x = 10

EF=2x-12-------> EF=2*10-12-------> EF=8

FG= 3x-15------> FG=3*10-15------> FG=15



therefore


the answer part a) is

the value of x is 10


the answer part b) is

the value of EF is 8


the answer part c) is

the value of FG is 15

Determine the x- and y-intercepts of the graph of y=1/4x−2 .
KATRIN_1 [288]
To find the x-intercept, put in 0 for the y.

0=1/4x-2
2=1/4x
8=x

The x-intercept is 8. The point is (8, 0).

To find the y-intercept, put in 0 for the x.

y=1/4(0)-2
y=0-2
y=-2

The y-intercept is -2. The point is (0, -2).

To graph, find the points on a coordinate plane and draw a straight line through them.

Hope this helps!
