The equations of two lines are given. Determine if the lines are parallel, perpendicular, or neither.8x - 7y = 6
8x - y = -8

Answers

Answer 1

Answer:

Answer:

8x-7y=6

or, -7y=-8x+6

or, y=8x/7-6/7

so the slope is 8/7

8x-y=-8

or, -y=-8x-8

or, y=8x+8

So the slope is 8

Both has different slope and they don't satisfy the property of being perpendicular to each others, so they're neither parallel nor perpendicular.

triangle NOP is similar to triangle QRS. Find the measure of Side SQ. Round your answer to the nearest tenth if necessary

Answers

The measure of side SQ from the given similar triangles is 40.9 units.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, triangle NOP is similar to triangle QRS.

Since the triangles are similar,

NP/SQ = NQ/QR

10/SQ = 13/53.2

13SQ=532

SQ=532/13

SQ=40.9 units

Therefore, the measure of side SQ is 40.9 units.

A trapezoid has an area of 975 square meters. The height of the trapezoid is 50 meters, and the length of the longer base is twice that of the shorter base. Find the length of each base of the trapezoid.

Answers

Area of trapezoid(A) =(1/2) (b1 + b2)*h

b1= x - shorter base
b2=2x - longer base
A=975 m²
h=50 m

975 =(1/2) (x + 2x)*50
975 = 25*3x
975 = 75x
x=975/75 = 13 m

x= b1 = 13 m
b2=13*2=26 m

b1=13 m,
b2 = 26 m,

2x+3y=-11, and x=2y+12 solve in substition equations

Answers

The answer would be (2,-5)

Because you know the equation for what x is, you can substitute (2y+12) for x. Your new equation would look like this;

2(2y+12)+3y=-11

Distribute the 2 into 2y+12

4y+24+3y=-11

Add 4y and 3y

7y+24=-11

Subtract 24 from both sides

7y=-35

y=-5

Now, substitute -5 in for y in the 2nd equation.

x= 2(-5)+12
x=-10+12
x=2

x=-5
y=2
