Step-by-step explanation:
Let height of a banner be , then we know that this is
of the length
of the banner; so we have
.
Now we can rearrange this equation to solve for the length of the banner given it's height:
So there we have it!
If the banner is 5 ft tall, then it's length will be:
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x + 2y = 7 into this form
Subtract 3x from both sides
2y = - 3x + 7 ( divide all terms by 2 )
y = - x +
← in slope- intercept form
with y- intercept c = → C
|2x + 12| = 18
First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. /
Subtract 12 from both sides. /
Subtract 18 - 16. /
Divide both sides by 2. /
Simplify. /
Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. /
Add 12 to both sides. /
Add 18 + 12. /
Divide both sides by -2. /
Simplify. /
Simplify. /
Fourth, collect the solutions. /
