Step-by-step explanation:
y=-3+5x
substitute y into equation 2
3x-8y=24
3x-8(-3+5x)=24
3x+24-40x=24
x=0
y=-3+5(0)
y=-3
(x,y)=(0,3)
Answer:
The final answer is 11.9
Step-by-step explanation:
14 x 6 = 84
84/5 = 16.8
16.8 - 4.9 = 11.9
Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
Answer:
B (Base surface area) = 16
P (Perimeter of the base) = 16 m
H (Height) = 6 m
L (Not sure what L means. I assume it's the slant height??) = 6.32 m
LA (I assume lateral surface area) =
SA (I assume total surface area) =
V (volume) =

Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.
Answer:
7 = -x^2 +16
x^2 -16 = 7
x^2 -23 = 0
Using quadratic equation
x = -0 +- sqrt (23^2 - 4*1*23) / 2 * 1
x = sqrt (0 - -92) / 2
x = sqrt (92) / 2
x1 = 4.7958
x2 = -4.7958
