. If B is a complement of A, and C is a supplement of B, find these measures. A
equals 40
Answers
so if A and B are complementary....and A = 40, then B = 90 - 40 = 50.
supplementary angles add up to 180
so if B and C are supplementary, and B = 50, then C = 180 - 50 = 130

A function is even if f(x)=f(-x) for every x in the domain.
f(x) is equal to f(-x) if and only if x=0, so the function isn't even.
A function is odd if -f(x)=f(-x) for every x in the domain.
-f(x) is never equal to f(-x), so the function isn't odd.
The function is neither even nor odd.

I have attached an image showing the sketch and the questions to answer.
Answer:
7) $1.28 per brick paver
8) 64 Sq.inches
9) $0.02 per Sq.inches
10) 0.4444 Sq.ft
11) 120 Sq.ft
12) Number of paver to cover patio = 270
Cost of that number = $345.6
Step-by-step explanation:
7) from the image attached, we can see that a box of 12 pavers cost $15.36.
Thus,cost of each brick paver = 15.36/12
>> $1.28 per brick paver
8) we see on the right of the image attached that the dimension of the brick paver is 8 inches length and 8 inches width.
Thus; square inches is the area = 8 × 8 = 64 Sq.inches
9) 1 paver has an area of 64 Sq. Inches. Thus, 12 pavers has an area of;
12 × 64 = 768 Sq.inches
Since cost of 12 pavers is $15.36
Thus coat per Sq inches of the pavers = 15.36/768 = $0.02 per Sq.inches
10) To find the Sq.ft each paver would cover, we will first convert the dimensions of the paver to ft.
Thus;
Length of 8 inches = 8/12 ft
Width of 8 inches = 8/12 ft
Area = (8/12) × (8/12)
Area = 4/9 Sq.ft = 0.4444 Sq.ft
11) The patio measures;
Length = 12 ft
Width = 10 ft.
Thus;
Area = 12 × 10 = 120 Sq.ft
12) Each paver has an area of 4/9 Sq.ft.
Thus;
Number of pavers to cover the patio = area of patio/area of each paver
Number of pavers to cover patio = 120/(4/9) = 270 pavers
12 pavers cost $15.36
Thus, 270 pavers will cost;
270 × 15.36/12 = $345.6

Answer:
The value of a = -2
Step-by-step explanation:
Given the equation: ax + 3y =48 .....[1] and it is passes through the point (-3, 14).
To find the value of a which completes the equation;
Substitute the point (-3 , 14) i.e, x = -3 and y = 14 in [1] to solve for a;
or
-3a + 42 = 48
Subtract 42 from both sides we get;
-3a + 42 -42 =48 -42
Simplify:
-3a = 6
Divide both sides by -3 we get;
a = -2
Substitute this value in [1] to completes the equation:
-2x + 3y =48
therefore, the value of a = -2 accurately completes the equation -2x + 3y =48
