8 0

Answer:

-y = 2.

Step-by-step explanation:

2x + 7y= 4

- 2x – 8y = -2  

Adding we eliminate   x because 2x + -2x = 0:-

0 - y = 4  + -2

-y = 2.

In Rhombus ABCD if BD is 24 ft and AD is 15 ft, then what is the length of AC?
Evgen [1.6K]

Answer:

AC = 24ft

Step by Step Explanation.

Given.

Rhombus.

BD = 24ft

AD = 15ft

Required

Length of AC

A rhombus has 4 equal sides; hence, the given shape will be regarded as a parallelogram and not rhombus (see attachment for diagram)

The opposite sides of a parallelogram are always of equal length

From the attached diagram (not drawn to scale), side AC opposites side BD

Given that BD = 24ft, then

AC = BD = 24ft.

Hence, AC = 24ft

Write an equation of the line that has a slope of 5 and goes through the point (3,3)
professor190 [17]

Answer:

y=5x-12

Step-by-step explanation:

The general equation of a line is <em>y=mx+b</em>.

The equation you currently have is <em>y=5x+b</em>.

Plug in the point (3,3) which will get you <em>3=5(3)+b</em>.

Solve the equation by solving what the y-intercept (b) is to create the new final equation.

3=5(3)+b

3=15+b

b=3-15

b=-12

y=5x-12
