Answer:2
Step-by-step explanation:
Ok so you can take this as a substitution problem.
x=-2y-13
then substitute
12(-2y-13)+5y=-4
--24y-13×12+5y=-4
sorry i gotta go
15- 10 divided by 21- -9 should give you your slope
Answer:
well then you fail and thats that
Step-by-step explanation:
Answer: C . 147π / 4 mi²
Concept:
The sector is the part of a circle is enclosed by two radii of a circle and their intercepted arc.
A = (θ / 360) πr²
θ = angle of the sector
π = constant
r = radius
Solve:
<u>Given variable</u>
θ = 270°
r = 7 mi
<u>Given formula</u>
A = (θ / 360) πr²
<u>Substitute values into the formula</u>
A = (270 / 360) π (7)²
<u>Simplify exponents</u>
A = (270 / 360) π 49
<u>Simplify by multiplication</u>
A = (147 / 4) π
A = 147π / 4
Hope this helps!! :)
