Answer:
answer is:

Step-by-step explanation:
we are asked to find which system of equations can we use to find the roots of the equation:

since the system of equation in last part is given as:

so, on equating both the equations i.e. on equating both the values of 'y' we get the desired equation as:
.
Answer:
EF=22
C=70°
B=110°
Step-by-step explanation:
Trapezoids have to have a total of 360° and there are complementary angles.
150 lbs on Earth is equal to 50 pounds on Mars
60 lbs on Earth is equal to _____
Set up a proportion.

Cross multiply.


The person would weigh 20 lbs on Mars.
The equation of line perpendicular to given line through (-6,7) is:

Further explanation:
Given equation of line is:

The co-efficient of x is the slope of given line.
Let m1 be the slope of given line
and
m2 be the slope of line perpendicular to given line
Then

Product of slopes of perpendicular lines is -1

The equation of new line can be written as:

Putting m2

To find the value of b, we will put (-6,7) in equation

Putting the values of b and m in general equation
