Answer:

C) Izzy

Step-by-step explanation:

Justin typed 90 words in 2 minute:

work

405/9=45 words a minute

45*2=90

Remmy typed 84 words in 2 minute:

work

420/10=42 words a minute

42*2=84

Izzy typed 98 words in 2 minutes:

work

588/12= 49 words a minute

49*2 = 98

I hope this helps :)

Answer:

Step-by-step explanation:

We need to find how many words each of them can type in 2 minutes.

Justin-

Justin can type 135 words in 3 minutes. First, find how many words he can type in 1 minute:

135/3 = 45 words per minute

Then, multiply by 2 to find how many words he can type in 2 minutes:

45 * 2 = 90

90 < 95, so he is eliminated.

Remmy-

Do the same as we did for Justin. Find the number of words she can type in 1 minute:

168/4 = 42

Multiply by 2:

42 * 2 = 84 words per minute

84 < 95, so she is eliminated.

Izzy-

Find the number of words she can type in 1 minute:

147/3 = 49 words per minute

Multiply by 2:

49 * 2 = 98

98 > 95, so she can type a minimum of 95 words every 2 minutes.

The difference of two numbers is 192, the sum is 3782

LenaWriter [7]

(3782 - 192) : 2 = 1795 (first number)

1795 + 192 = 1987 ( second number)

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

1987 - 1795 = 192

1987 + 1795 = 3782

The linear function graphed below represents the value of a comic book since Lucy purchased it. What was the value of the comic

zhuklara [117]

Answer:

C. $25

Step-by-step explanation:

We will find,

The slope of the function using $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

Taking the points (1,40) and (2,55).

Slope = $\frac{55-40}{2-1}$

i.e. Slope = $\frac{15}{1}$

i.e. Slope = 15

Substituting the slope and point (1,40) in the equation $y=mx+b$ ,

We have, $40=15\times 1+b$

i.e. $b=40-15$

i.e. b= 25

Thus, the equation of the linear function is $y=15x+25$ .

<em>This linear function represents the cost of the comic book since Lucy purchased it, where x= years.</em>

So, the initial value of the comic book is when x= 0.

So, $y=15\times 0+25$ i.e. y= 25

Hence, the cost of the book when Lucy purchased it was $25.

Roblem #7

gtnhenbr [62]

Answer:

no solution.

Step-by-step explanation:

1) in order to explain, the given system should be resolved:
$\left \{ {{2y=6x+4} \atop {y=3x-4}} \right. \ < = > \ \left \{ {{y=3x+2} \atop {y=3x-4}} \right.$

2) the both equations have the same slope (it is 3), it means the given lines are parallel, then no solution.
