1. $y=7x-1$

2. $y=3x+b$
 Sub (1, -5) into equation to find 'b'
$-5=3(1)+b$
$-8=b$

$y=3x-8$

3. $x=-7$

4. $y=4$

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving

Zarrin [17]

Answer: The function that models the distance they drive is

f(x) = 50x + 20 where x is the time in hours

reasonable domain: 0 ≤ x ≤ 3

Step-by-step explanation:

examples:

95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.

120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.

There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t

20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.

120 = 5(2.4) The whole trip took 2.4 hours.

Andre says that 5 3/4 + 2 1/4 = 7 1/2 because 7 4/8 = 7 1/2. Identify his mistake. Draw a picture to prove that he is wrong.

MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

The given expression is

$5\frac{3}{4}+2\frac{1}{4} =7\frac{4}{8}=7\frac{1}{2}$

We will rewrite the expression

$\frac{23}{4}+\frac{9}{4} =\frac{60}{8}=7\frac{1}{2}$

When we add the fraction

$\frac{23+9}{4}$ = $\frac{32}{4}$ = 8

While Andre says the answer is $7\frac{1}{2}$

because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.

Andre made mistake in this step
