Answers:

Answer for A is 1

Answer for B is 3

Answer for C is 0.5

Answer for D is Table.

Step by step explanation:

Figure shown graph of a line

Table of x and y value are given as

X    Y

0    3

1     6

2    9

3    12

The equation of a line is given as y=0.5x+1

QA). What is the slope of the line in the graph

Ans.

The slope is given as s=\frac{Y2-Y1}{X2-X1}

In the graph, the line passing through points (0,5)(-5,0)

The slope of a line:

s=\frac{Y2-Y1}{X2-X1}

s=\frac{0-5}{(-5)-0}

s=1

The slope of the line in the graph is 1

QB). What is the slope of the line in the table

Ans.

The slope is given as s=\frac{Y2-Y1}{X2-X1}

In the table, the line passing through points (0,3)(1,6)

The slope of a line:

s=\frac{Y2-Y1}{X2-X1}

s=\frac{6-3}{(1-0}

s=3

The slope of the line in the table is 3

QC). What is the slope of the line in the equation

Ans.

The equation of a line is given as y=mx+c

The equation of a line is y=0.5x+1

Where m= slope

On comparing both the equation we get,

m=0.5

The slope of line in the equation is 0.5

QD). Which has the greatest rate of change

Ans.

The slope of the line in the graph is 1

The slope of the line in the table is 3

The slope of the line in the equation is 0.5

There, Rate of change is also called as the slope and it is greatest in case of the table.

How many liters each of a 35% acid solution and a 80% acid solution must be used to produce 60 liters of a 65% acid solution? (R
serg [7]

Solving a system of equations we will see that we need to use <u>40 liters of the 80% acid solution</u>, and the other <u>20 liters are of the 35% acid solution</u>.

<h3>How many liters of each solution do we need to use?</h3>

First, we need to define the variables:

  • x = liters of the 35% acid used.
  • y = liters of the 80% acid used.

We know that we want to produce 60 liters of 65% acid, then we have the system of equations:

x + y = 60

x*0.35 + y*0.80 = 60*0.65

(in the second equation we wrote the percentages in decimal form).

To solve this we need to isolate one of the variables in one equation and then replace it in other one, isolating x we get:

x = 60 - y

Replacing that in the other equation:

(60 - y)*0.35 + y*0.80 = 60*0.65

y*(0.80 - 0.35) = 60*(0.65 - 0.35)

y*0.45 = 60*0.30

y = 60*0.30/0.45 = 40

So we need to use <u>40 liters of the 80% acid solution</u>, and the other <u>20 liters are of the 35% acid solution</u>.

Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r
Aleks [24]

Answer:

<em>The expression that represents her gross pay each day will be:  (5h+8) dollars.</em>

Step-by-step explanation:

Suppose, Harriet's gross pay each day = x

So, her total gross pay for 7 work days =7*x= 7x

Given that, her gross pay at the end of 7 work days is (35h + 56) dollars.

So, the equation will be.......

7x= 35h+56 \\ \\ x=\frac{35h+56}{7}\\ \\ x=\frac{35h}{7}+\frac{56}{7}\\ \\ x=5h+8

Thus, the expression that represents her gross pay each day will be:  (5h+8) dollars.
