QUESTION 1
We want to solve the linear equation,
–12 + 3b – 1 = –5 – b
Group similar terms:
3b+b=-5+1+12
Combine similar terms,
4b=8
Divide both sides by 4
b=2.
QUESTION 2
We want to find the equation of the given line that passes through
(-3,2) and (2,-1)
The slope of this line is
The equation is given by the formula:
We plug in the known values to obtain;
Answer:
18(40/360) + 9( 140/360) -3(90/360) -7(90/360)
=2 + 3.5 - 0.75 - 1.75
= $3
Answer:
The correct option is;
B. The difference of 2 perfect squares
Step-by-step explanation:
Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation
In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.
For example, we have;
x² - 5² = 11
We subtract 11 from both sides to get;
x² - 5² - 11 = 11 - 11
x² - 36 = 0
x² - 6² = 0
(x - 6) × (x + 6) = 0
Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.
Answer:73
Step-by-step explanation:
Answer:
$113.40
Step-by-step explanation:
The dress is $180 subtracted by 30% ($54) and is now $126
$126 - 10% which is $12.60 and is now $113.40
