Answer:
Step-by-step explanation:
The equation starts out as 4.8x - 3.7 = 14.7,
Then you have to isolate the x variable to get: 4.8x = 14.7 + 3.7
It is + 3.7 because you have to do the inverse operation
Finally the equation becomes 4.8x = 18.4
So x = 3.833333333 repeating
Answer:
9
Step-by-step explanation:
Square root is to multiply same number to get high number.
Example: square root of 81.
9 x 9 = 81
(5, 0)
(5, 0) and (–5, –80)
no solutions
Answer:
(5, 0 )
Step-by-step explanation:
Given the 2 equations
y = x² - 2x - 15 → (1)
y = 8x - 40 → (2)
Substitute y = x² - 2x - 15 into (2)
x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )
x² - 10x + 25 = 0 ← in standard form
(x - 5)² = 0 ← in factored form, thus
x - 5 = 0 ⇒ x = 5
Substitute x = 5 into (2) for corresponding value of y
y = 8(5) - 40 = 40 - 40 = 0
Solution is (5, 0 )
