Answer:

Q. 2)Perimeter =2(l+b)

So,

2(8x-8 +8x)=80cm(Given in Question)

= 2*16x-8=80cm

16x- 8= 80 divided by 2,

16x=40+8=48

x=48 divided by 16

X=3

Q.1) Perimeter=2(l+b)

2(2x+8 +4x)=76cm(Given in Question)

2* 6x +8=76

6x+8= 76 divided by 2, 38

6x= 38-8, 30

x= 30 divided by 6 = 5

X=5

divide by 3 on both sides

n=16

How do you sovle 5x-4+7x=5(2x-4)

Answers

Answer:

x = -8

Step-by-step explanation:

5x - 4 + 7x = 5(2x - 4)

12x - 4 = 10x - 20

    +20          +20

12x + 16 = 10x

-12x          -12x

Which equation has a slope of –52 and a y-intercept of –2?
A. –5x – 2y = –4
B. –5x – 2y = 4
C. 5x + 2y = 4
D. 5x + 2y = –4

Answers

Answer:

I'm sure there might be a typo in the question (AKA the slope is -5/2)

but the answer would be

D

Step-by-step explanation:

y= mx+ b

where m is the slope, and b is the y intercept

y= -52x -2

..........

5x + 2y = –4

2y= -5x -4

y= - 5/2x -2

[tex]y = - \frac{5}{2} x - 2[/tex]

What is the solution to the system of equations? One-fourth x minus one-half y = 8 One-half x + three-fourths y = negative 5 (–8, –12) (–8, 12) (8, 12) (8, –12)

Answers

Answer:

Step-by-step explanation:

x/4-y/2=8, x-2y=32, x=32+2y

x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2

32+2y=(-20-3y)/2

64+4y=-20-3y

7y=-84

y=-12, since x=32+2y

x=32+2(-12), x=32-24=8

So the solution is the point (8, -12)

its (8, -12)
