Answer:

b, y = 9x + 7

Step-by-step explanation:

Since the graph y = 9x + 10 is being "translated" 3 units down, that means the slope of the equation remains the same, but the y intercept is being moved 3 units down.

y = mx + b

y-intercept = b = 10

10 - 3 = 7

the answer is b, y = 9x + 7

Gary is 25 years old. That is 7 more than
SpyIntel [72]

Answer:

2<em>x </em>+ 7 = 25

<em>x </em>= 7

Step-by-step explanation:

Gary: 25

Sean: <em>x</em>

----------------------------

Let's break down the sentence into mathematical terms

Gary <u>is</u> 25 years old. That <u>is</u> 7 more than twice <u>Sean's age.</u>

In math, is means equal to. It is represented with an equal sign (=)

Gary = 25. 25 = 7 more than twice <u>Sean's age.</u>

7 more is represented by 7 +

Gary = 25. 25 = 7 + than twice <u>Sean's age.</u>

Twice means double which is 2 ·

Gary = 25. 25 = 7 + 2 · <u>Sean's Age</u>

<u>Sean's Age</u> will be represented by <em>x</em>

Gary = 25. 25 = 7 + 2<em>x</em>

We don't need it to say<em> "Gary = 25" </em>in our equation.

25 = 7 + 2<em>x</em>

Let's rewrite it with the associative property.

2<em>x </em>+ 7 = 25

---------------------

Now, solve

2<em>x </em>+ 7 = 25

<em>-7           -7</em>

2<em>x</em> = 18

<em>÷</em><em>2  </em><em>÷</em><em>2</em>

<em>x </em>= 7

----------------------

Sean is 7 years old.
