Answer:
x=−7
Step-by-step explanation:
(x+4)(2)−3(x+4)−3=0
(x)(2)+(4)(2)+(−3)(x)+(−3)(4)+−3=0(Distribute)
2x+8+−3x+−12+−3=0
(2x+−3x)+(8+−12+−3)=0(Combine Like Terms)
−x+−7=0
To solve for a variable, you need to get it (x) by itself.
x² - 14 + 31 = 63 Add 31 to -14
x² + 17 = 63 Subtract 17 from both sides of the equation
x² = 46 Square root both sides
x =

Check your work by plugging in

for x and then

.

² - 14 + 31 = 63 Square

46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63

² - 14 + 31 = 63 Square

46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
So,
x is
and 
.
Answer
$60+1/4c=$147.50
Step-by-step explanation:
makes $60 a day
1/4 of customer sales= 1/4 c
equal 147.50
so 60+ 1/4 c = 147.50
Answer:
one solution
Step-by-step explanation:
they have different slopes and are linear
Ok, so what this means is if it's negative, leave it. if it's positive, make it negative
so the range would be -5,-3,0,-3,-5
point are
(-5,-5)
(-3,-3)
(0,0)
(3,-3)
(5,-5)
