Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
x + 3y = - 1 → (1)
- 2x - 3y = 5 → (2)
Adding the 2 equations term by term will eliminate the y- term
- x + 0 = 4
- x = 4 ( multiply both sides by - 1 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
- 4 + 3y = - 1 ( add 4 to both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (- 4, 1 )
Answer:
<P = 56 degrees
Step-by-step explanation:
Given the following
m<R = 90 degrees
QR = 61feet = Adjacent
RP = 90 feet= Opposite
Required
tan<P = opp/adj
Tan<P = 90/61
<P = arc tan (90/61)
<P = arctan 1.4754
<P = 55.9
<P = 56 degrees to the nearest degree
Answer:
70 square inches
Step-by-step explanation:
We have to find the area of the rectangle and this would help us determine how much paint he would need to paint his rectangle
Area of a rectangle = Length × Width
Length = 10 inches
Height = 7 inches
Area of the rectangle = 10inches × 7 inches
= 70 square inches
Therefore, he would be needing 70 square inches of paint in order to paint his rectangel
