Answer:

1.9x+3.7

Step-by-step explanation:

Subtract 3.6x-1.7x

and 5.9-2.2    

The solution is 1.9x + 3.7

The value of the equation is given as A = 1.9x + 3.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 3.6x + 5.9 - 2.2 - 1.7x   be equation (1)

On simplifying the equation , we get

On grouping the similar terms

The value of A = ( 3.6x - 1.7x ) + ( 5.9 - 2.2 )

The value of A = 1.9x + 3.7

Therefore , the value of A is 1.9x + 3.7

Hence , the equation is A = 1.9x + 3.7

Step-by-step explanation:

Answer:

[tex]y=\frac{-2}{3} x+1[/tex]

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex]. Here's what the variables mean:

y = the y-coordinate

m = the slope

x = the x=coordinate

b = the y-intercept (what y is equal to when the line crosses the y-axis)

First, we need to calculate the slope of the line (m). The slope is the [tex]\frac{rise}{run}[/tex] of the line, or in other words, the change in y over the change in x. We can find this by just looking at the graph, between the two given points. For 3 spaces the line travels to the right, it travels downward 2 spaces. Therefore, the slope of the line is [tex]\frac{-2}{3}[/tex].

We can also calculate this using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] by using two points that fall on the line, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. Here, we can use the points (-3,3) and (0,1).

[tex]\frac{y_2-y_1}{x_2-x_1}\\\frac{1-3}{0-(-3)}[/tex]

Two negatives make a positive

[tex]=\frac{1-3}{0+3}\\=\frac{-2}{3}[/tex]

Then, we need to find the y-intercept of the line (b). We can find this by, again, looking at the graph. The line crosses the y-axis when y is equal to 1, so the y-intercept of the line is 1.

Now, we plug our calculated values back into the original equation:

[tex]y=mx+b\\y=\frac{-2}{3} x+1[/tex]

Use the equation 500x0.04x20 and then 500x20 and add the sums up and get 10,400 i believe is im wrong sorry :/

$900 is the total amount of money she has after 20 years.

Simple interest is, by definition, the amount of interest paid on a specific principal sum of money when an interest rate is applied. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

From the formula of simple interest A = P(1 + rt)

Where A = amount earned

P = principal amount

r = rate of interest

t = time

In our case

P = 500

r = 4%

t = 20

Thus,

Amount earned after 20 years = 500(1 + 4*20/100)

Amount earned after 20 years = 500(1 + 4/5)

Amount earned after 20 years = 900

therefore, the total amount of money she has after 20 years is $900.

Answer:

y= 3/2 x -2

Step-by-step explanation:

I guess you want to find the y=mx+b form

So you do +3x on both sides which will gave you: 2y= 3x-4

Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2

So 3/2 is the fraction like the answer above and -4/2 = -2

Answer:

y = x-3 is the equation

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

The general equation form of a straight line is;

y = mx + b

Fro the equation;

y = -1x + 2

The slope is -1

So the equation of the perpendicular line is as follows;

-1 * m = -1

m = 1

so we can use the point-slope equation form

That would be:

y-y1 = m(x-x1)

y-3 = 1(x-6)

y-3 = x-6

y = x-6+3

y = x-3

Given:

Measure of exterior angle = 164°

The measure of opposite interior angles are x° and 53°.

To find:

The value of x.

Solution:

According to the Exterior Angle Theorem, in a triangle the measure of an exterior angles is always equal to the sum of measures of two opposite interior angles.

Using Exterior Angle Theorem, we get

[tex]x^\circ+53^\circ=164^\circ[/tex]

[tex]x^\circ=164^\circ-53^\circ[/tex]

[tex]x^\circ=111^\circ[/tex]

[tex]x=111[/tex]

Therefore, the value of x is 111.

Answer: 23 years

Step-by-step explanation:

From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:

= 364 / 16

= 22.75 years

= 23 years approximately

Answer:

2 or C

Step-by-step explanation:

I'm taking this to mean

4 = 2(x - 1)^2

4 = 2(x^2 - 2x + 1)

4 = 2x^2 - 4x + 2

2x^2 - 4x - 2  =  0

x^2 - 2x - 1 = 0

What you get from here is sqrt(2) as one of the roots.

That is not nearly an answer.

4 = 4(x -1)

4 = 4x - 4

8 = 4x

x = 8/4

x  =  2

That makes C the answer.
