For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
Answer:
y = - 7
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (5, - 7) with y- coordinate - 7, thus
y = - 7 ← equation of horizontal line
I should be <span>C. 1 3/4 if I'm not mistaken</span>
Answer:
Option C.
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its perimeter is equal to the scale factor too
step 1
Find the width of the rectangle that has a length of 4 feet and a perimeter of 14 feet
The perimeter of a rectangle is equal to
substitute the values and solve for W
step 2
Find the scale factor
Let
z-----> the scale factor
To find the scale factor divide the width of the larger rectangle by the width of the smaller rectangle
so
step 3
Find the perimeter of the larger rectangle
To find the perimeter of the larger rectangle multiply the perimeter of the smaller rectangle by the scale factor
so
