Answer:
Step-by-step explanation:
To determine the inverse of an equation, simply switch the places of the 'x' and 'y' variables. Therefore:
f(x) = -2x + 3
Use 'y' in place of f(x).
y = -2x + 3
Switch the 'x' and the 'y':
x = -2y + 3
Subtract '3' from both sides:
x - 3 = -2y
Divide both sides by '-2':
Simplify:
First solve the addition part:
5^7 + 5^6 =
78125 + 15625 = 93750
Now divide the total by 6:
93750 / 6 = 15625
Because the answer is a whole number ( no decimal) it is divisible by 6.
Answer:
$8.40
Step-by-step explanation:
A store sells ½ pound of beef for $0.70
We find the unit rate
1/2 pound = $0.70
1 pound =
We cross Multiply
1/2 × x = 1× 0.70
x = 0.70 ÷ 1/2
x = 0.70 × 2/1
x = $1.40
The unit rate for 1 pound of beef is $1.40
If you are having a party and need 6 pounds of beef for hamburgers
Hence, the cost for 6 pounds of beef is:
1 pound = $1.40
6 pounds = y
y = 6 × $1.40
y = $8.40
6 pounds of beef for hamburgers would cost $8.40
<span>As you look at the graph from left to right (increasing x), if the line is going up(increasing y), slope is positive.
.
If it's going down (decreasing y), slope is negative.

Answer:
The answer is C
Step-by-step explanation:
You have to isolate the variable by dividing each side by factors that don't contain the variable.
Hope it helps.
