4 times 0.8 = 3.2
0.6 times 0.8 = 0.48
Answer:
a. y = -1/4x - 6
Step-by-step explanation:
slope intercept formula is y = mx + b with m being the slope, b being the y-intercept, and y and x being any point on the line
so plug in the slope and coordinates to solve for b
-7 = (-1/4) × 4 + b
solve for b by simplifying
b = -6
we have
we know that
The absolute value has two solutions
Subtract both sides
Step 1
Find the first solution (Case positive)
Subtract both sides
Multiply by both sides
Step 2
Find the second solution (Case negative)
Adds both sides
<u>Statements</u>
<u>case A)</u> The equation will have no solutions
The statement is False
Because the equation has two solutions------> See the procedure
<u>case B)</u> A good first step for solving the equation is to subtract 0.5 from both sides of the equation
The statement is True -----> See the procedure
<u>case C)</u> A good first step for solving the equation is to split it into a positive case and a negative case
The statement is False -----> See the procedure
case D) The positive case of this equation is 0.5 – |x – 12| = 0.25
The statement is False
Because the positive case is -----> see the procedure
case E) The negative case of this equation is x – 12 = –0.75
The statement is True -----> see the procedure
<u>case F)</u> The equation will have only 1 solution
The statement is False
Because The equation has two solutions------> See the procedure
