Answer:

A = 30m + 35

Step-by-step explanation:

let A be the amount saved and m represent month

Note the difference in the amount saved is constant, that is

185 - 155 = 155 - 125 = 125 - 95 = 95 - 65 = 30

We can express this as

A = 30m + c

To find c use any pair from the table and substitute into the equation

using (3, 125) then

125 = (3 × 30) + c

125 = 90 + c ( subtract 90 from both sides )

c = 125 - 90 = 35, thus

A = 30m + 35 ← linear relationship

As a check

When m = 4, A should be 155

A = (4 × 30) + 35 = 120 + 35 = 155 ← correct

Linear function representing the table is

A(m) = 30m + 35

Enter an inequality that represents the graph in the box.

ANTONII [103]

The inequality that represents the graph in the box is

$y>-3x+6$

Given :

The graph of the linear inequality

Lets pick two points from the graph to frame the linear equation

Slope intercept form of the equation is

$y=mx+b$

Where m is the slope and b is the y intercept

y intercept is (0,6) from the graph

so b=6

Now we find out slope m using formula

Pick two points (0,6) and (2,0)

$slope = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{0-6}{2-0} =-3$

m=-3

So the equation is $y=-3x+6$

Now we check the inequality sign by testing any point on shaded area

lets pick (4,0)

lets plug in 4 for x and 0 for y

$y=-3x+6\\0=-3(4)+6\\\\0=-6\\0>-6$

The inequality for the given graph is

$y>-3x+6$

we cannot use >= sign because we have dotted lines

The heights of two similar parallelograms are 16 inches and 20 inches. Their

Fittoniya [83]

Answer: $x=\dfrac{25}{21}$

Step-by-step explanation:

Area of parallelogram = Base x height

If two parallelograms are similar, then their corresponding sides are proportional.

That means, $\dfrac{\text{Area of first parallleogram}}{\text{Area of second parallleogram}}=\dfrac{\text{height of first parallelogram}}{\text{height of second parallelogram}}$

$\Rightarrow \dfrac{3x+5}{9x}=\dfrac{16}{20}\Rightarrow \dfrac{3x+5}{9x}=\dfrac{4}{5}\\\\\Rightarrow 5(3x+5)=4(9x)\\\\\Rightarrow\ 15x+25 = 36x\\\\\Rightarrow\ 36x-15x=25\\\\\Rightarrow\ 21x = 25\\\\\Rightarrow\ x=\dfrac{25}{21}$

Hence, $x=\dfrac{25}{21}$
