Step-by-step explanation:

The equation is in slope-intercept form, which is y = mx + b.

To graph the line, first we have to find the slope, m, and the y- intercept, b.

So, the slope is 2 and the y- intercept is 1.

We can graph this, beginning with the y- intercept, 1. The y- intercept is always on the y axis, so the (x) value will always be zero.

Plot a point at (0, 1).

Next, add more points using the slope. The slope is 2, or $\frac{2}{1}$ . Start at the point we have made on the y axis. The slope equals the $\frac{rise}{run}$ . We can rise 2 units, then run one more unit to the right. If the slope is negative, the run goes to the left. However, in this case, the slope is positive, to it slants to the right.

We end on point (1, 3). We can continue this path infinitely, some other points on the graph could be (2, 5), (3, 7), (4, 9) and (5, 11).

Connect these points to make a line.

The finished line is linked below as well.

I hope this helps :] Good luck ^^

3y+9y=192 write the solution set.

nekit [7.7K]

3 y + 9 y = 192

First, start off by adding your two number-variables:

12y = 192

Then, divide 12 by 192:

y = 16
Your answer should be 16.
Hopefully that helped! :)

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the doghouse?

Naya [18.7K]

First we will find the total measure of the second base.

Second base is extended more so that meas it will measure extended part plus the first base.

Second base = 7 + 5 = 12.

Now for the area.

A = 1/2(b1+b2)(h)
A = 1/2(7 + 12)(7)
A = 66.5

The area is 66.5 ft²

Hope this helps :)

In ΔSTU, the measure of ∠U=90°, TU = 3.7 feet, and ST = 5.2 feet. Find the measure of ∠S to the nearest tenth of a degree.

tekilochka [14]

Answer:

45.4°

Step-by-step explanation:

The angle and side lengths in a right triangle are related by ...

Sin = Opposite/Hypotenuse

sin(S) = TU/TS = 3.7/5.2

Using the inverse sine function, we have ...

∠S = arcsin(3.7/52)

∠S ≈ 45.4°

Tess needs to buy sand for her children’s playground. The sand costs $8 per ton, and there is a delivery cost of $50 with each o

Butoxors [25]

Answer:

All positive rational numbers greater than 50

Step-by-step explanation:

Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation

y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58

Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50

A tree 5 feet tall grows an average of 8 inches each year. Write and graph an equation to model the tree's height h after x year

Stolb23 [73]

Okay my example will be for if you watched that tree for like 5 years and I can`t really put in a graph here so sorry about that

The equation is basically the original height, 5 foot, and multiply it by the number of years you`ve been watching it grow for example when you watch it for 6 years then it will be the original height of 5 foot multiplied by the number years it has been since you look at it which is 6 years. 5 * 6 = 30 so after 6 years it will grow 30 inches.
1st year: 5 foot
2nd year: 5 foot * 2 = 10 inch increase in height
3rd year: 5 foot * 3 = 15 inch increase in height
4th year: 5 foot * 4 = 20 inch increase in height
5th year: 5 foot * 5 = 25 inch increase in height
So basically the equation is 5 foot * the number of years its been = total increase in height

I hope this helps
