Answer:
You may or may not need to include the units.
A = 18x - 18
P = 6x + 6
Graph is attached below. (2, 18)
Step-by-step explanation:
Substitute the information we need, "l" and "w", into the formulas.
l is for length, 6cm.
w is for width, (3x - 3)cm.
Use the formula for area of a rectangle.
A = lw
A = (6)(3x-3)cm²
A = (18x - 18)cm² or 18x - 18
Use the formula for perimeter of a rectangle.
P = 2(l + w)
P = 2(6 + (3x - 3))cm
P = 2(3x + 3)cm
P = (6x + 6)cm or 6x + 6
Linear equations are written in the form y = mx + b, so we do not need to factor or further simplify the formulas.
To graph, first turn the "m" value into a fraction form.
8 -> 8/1
6 -> 6/1
You need two points to graph each line.
For each equation, the first point is on the y-axis at the "b" value. Then use the "m" in the equation to count the number of units up (numerator) and to the right (denominator).
The solution is (2,18)
Answer:
gallons
Step-by-step explanation:
If gallons fill of a bucket.
Then we can write the ratio;
Let gallons fill the entire bucket which is equivalent to .
Then we can again write the ratio;
We can write the following equation of proportion to solve for .
This implies that;
We simplify to get;
Therefore gallons will fill the entire bucket
Answer:
A. No, because the product of the slopes is not -1
Step-by-step explanation:
The slope of a line that passes through points (x1, y1) and (x2, y2) is computed as follows:
m = (y2 - y1)/(x2 - x1)
Therefore:
Two lines are perpendicular if the product of their slopes is equal to minus one. In this case, m1*m2 = 3*(-0.4) = -1.2 ≠ -1
Answer:
Yes, because the product of the slopes is −1.

Answer:
Scale did the architect use to create the scale of the sports stadium is 1 inch = 15 feet.
Step-by-step explanation:
Given : An architect build a scale model of a sports stadium that was 12 inches. The actual height of the building was 180 feet.
To find : Which scale did the architect use to create the scale of the sports stadium?
Solution :
An architect build a scale model of a sports stadium that was 12 inches.
The actual height of the building was 180 feet.
The scale is determined by number of feet used in 1 inch.
i.e. For 12 inches it is 180 feet
For 1 inch = feet
1 inch = 15 feet
Therefore, scale did the architect use to create the scale of the sports stadium is 1 inch = 15 feet.
