Answer:
10x=y.
Step-by-step explanation:
10 represents the amount he earns an hour. X represents the number of hours so 10x. 10 times the amount of hours equals y (total amount of money)
We are given the following function:

We are asked to do the following tranformations:
1. Shift down 5 units and left 77 units.
First, to shift a function down a number "n" of units we follow the next rule:

And, to shift a function "m" units to the left we use the following rule:

Applying both rules simultaneously we get:

2. Reflect about the y-axis.
The rule to reflect a function about the y-axis is the following:

The means that we will change "x" for "-x" in the function we are going to reflect. Applying the rule we get:

3. Compress vertically by a factor of 2.
To compress a function vertically by a factor "m" we multiply the entire function by 1/m, like this:

Applying the rule we get:

And thus we get to the final function.
Answer:
x = -2
Step-by-step explanation:
x^2 - 3x - 10 when we factorize equals
(x + 2) (x - 5)
3x^2 + 5x - 2 when we factorize equals
(3x - 1) (x + 2)
x + 2 is the common term and when we put the 2 on the other side of the equation we get x = -2
Answer:
W times H
Step-by-step explanation:
Answer/Step-by-step explanation:
7x- 4 = -182
<em>Step:</em>
Add 4 to both sides
7x - 4 + 4 = -182 + 4
Simplify
7x = -178
Divide both sides by 7
7x/7 = -178/7
Simplify
x = -178/7
Decimal form = -25.4285714286
