8x + By + 92 = 0
(-4; 12) ⇒ x = -4; y = 12
subtitute
8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12
B = -5
First subtract 4 from both sides
then simplify
add -5 to both sides
since a variable shouldn't be negative the answer should be
(I prefer having the variable on the left side)
Answer:
AC = 18, EB = 5 Step-by-step explanation:In a rhombus, AE = CE, and DE = BE. However, AE or AC ≠ DE or BE.
CE = AE
= 9
AC = CE + AE
= 9 + 9
= 18
DE = BE
= 5
Answer: p = 75 + 250
Equation of the situation, in slope-intercept form is given as .
Where,
b = y-intercept
m = slope
n = number of computers sold
p = total cost
All we need to find is the value of m and b.
Using two pairs from the table of values, (4, 550) and (6, 700):
Substitute n = 4, p = 550, and m = 75 in , and find the value of b.
Subtract 300 from each side
b = 250
Substitute m = 75, and b = 250 in
✅Equation that represents the situation would be:
