Answer:

b-16/25

Step-by-step explanation:

cause 0.64 would be 64/100 but I can be simplified down to 32/50 but that also could be simplified down to 16/25 which would be your answer because it can not be simplified any more

y = - 4/3 x - 20/3

Step-by-step explanation:

x = - 3/4 y - 5   Move Terms

3/4 y = - 5 - x   Divide both sides

y = - 20/3 - 4/3 x     Reorder the terms

y = - 4/3 x - 20/3

Hint :- The slope intercept form of the line is [tex] y = mx + c [/tex] , where m is the slope of the line and c is y intercept .

Solution:-

Given equation to us ,

[tex]\implies x = \dfrac{-3}{4}y -5 [/tex]

Multiply both sides by 4 ,

[tex]\implies 4x = -3y -20 [/tex]

Add 20 to both sides ,

[tex]\implies 4x +20 = -3y [/tex]

Divide both the sides by -3 ,

[tex]\implies \dfrac{-4}{3}x-\dfrac{20}{3}= y [/tex]

Flip the equation ,

[tex]\implies y = \dfrac{-4}{3}x-\dfrac{20}{3} [/tex]

The equation of the line is represented in table number 2. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

From the graph, the y-intercept is 5. Then the equation is given as,

y = mx + 5

From the graph, the equation passes through (-4, -3). Then we have

- 3 = (-4)m + 5

- 8 = - 4m

m = 2

Then the equation is given as,

y = 2x + 5

The equation of the line is represented in table number 2. Then the correct option is B.

($1.75*5 pounds of apples)+($2.35*4 pounds of oranges)+($1.50*3 pounds of bananas) = $8.75+$9.40+$4.50 = $22.65

Overestimation

Answer:. the estimate would be 52 dollars

the actual number would be 48.25 dollars

(1.75*5)+(8.75*4)+(1.50*3)=48.25

Answer:

The answer would be $1.89 in interest.

Step-by-step explanation:

First, change 10.5% into a decimal. To do this, you divide 10.5÷100. This equals 0.105

next, you multiply 0.105 with 12 (12 months in a year)

This equals 1.26

But, Hector still has 6 months left he has to pay for.

So, one way you can do this is divide 1.26 by 2, which equals 0.63.

THEN, you add 0.63 with 1.26, giving you the answer, 1.89

So, the answer for this equation would be 1.89.

The feeders in battling machine are represented in proportions and fractions.

The given parameters are:

[tex]\mathbf{Initial = \frac 16x}[/tex] ------ 1/6 full

[tex]\mathbf{Additional = 15}[/tex] --- baseballs added

[tex]\mathbf{Final = \frac 23x}[/tex] ---- 2/3 full

So, the equation that represents the problem is:

[tex]\mathbf{Initial + Additional = Final}[/tex]

So, we have:

[tex]\mathbf{\frac 16x + 15 = \frac 23x}[/tex]

The number of baseballs it can hold is calculated as follows:

[tex]\mathbf{\frac 16x + 15 = \frac 23x}[/tex]

Multiply through by 6

[tex]\mathbf{x + 90 = 4x}[/tex]

Collect like terms

[tex]\mathbf{4x - x = 90 }[/tex]

[tex]\mathbf{3x = 90 }[/tex]

Divide through by 3

[tex]\mathbf{x = 30 }[/tex]

Hence, the feeder can hold 30 baseballs, when full

Answer: 10.5 small boxes

Step-by-step explanation:

Parallel lines have the same slope

The equation of the line is: [tex]\mathbf{y = \frac 23x + 8}[/tex]

From the question, we have:

[tex]\mathbf{2x - 3y = 5}[/tex]

Make y the subject

[tex]\mathbf{- 3y = 5 - 2x}[/tex]

Divide through by -3

[tex]\mathbf{y = \frac 23 x - 5}[/tex]

Because the required equation is parallel to [tex]\mathbf{2x - 3y = 5}[/tex], then they must have the same slope

A linear equation is represented as:

[tex]\mathbf{y=mx + c}[/tex]

Where:

m represents the slope

So, by comparison:

[tex]\mathbf{m = \frac 23}[/tex]

This means that:

The required equation has a slope of 2/3

The equation of the line is:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

Where:

[tex]\mathbf{m = \frac 23}[/tex]

[tex]\mathbf{(x_1,y_1) = (-9,2)}[/tex]

So, we have:

[tex]\mathbf{y = \frac 23(x + 9) + 2}[/tex]

Open brackets

[tex]\mathbf{y = \frac 23x + 6 + 2}[/tex]

[tex]\mathbf{y = \frac 23x + 8}[/tex]

Hence, the equation of the line is: [tex]\mathbf{y = \frac 23x + 8}[/tex]
