Examine the system of equations.

y = 2x – 3,

y = –3

Which statement about the system of linear equations is true?
The lines have different slopes.
There is no solution to the system.
The lines have the same slope, but different y-intercepts.
The solution is (–3, –9). can someone give me there insta and help me with my work i will pay you.

Answers

Answer:

Step-by-step explanation: Because if you add 2x3 it equals 6 so if u add 2x2 2 times thats ur answer when you add three.

Answer:
The first statement “The lines have different slopes” That’s the only true statement. In the equation y=2x-3 it tells us that the slope is 2, but in the other equation, it has no slope.

Reasoning behind the other statements:
It can’t be statement 2 because there is a solution. And the solution is (0,-3)

It can’t be statement 3 either because both equations DONT have the same slope, if they did, the graphs would be the same and will have infinite solutions. Also it says “different y-Intercepts” BUT they do have the same y- intercepts, and the y-intercept is -3

Now finally, the last statement isn’t true because like I mentioned earlier, the solution is (0,-3) NOT (-3,-9)

The volume of this cone is 3,183.96 cubic meters. What is the height of this cone?

Answers

Answer:

18 m

Step-by-step explanation:

Given,

Volume of the cone = 3183.96 cubic meters

Radius of the cone = 13 m

Therefore, by the problem,

[tex] = > \frac{1}{3} \pi {r}^{2} h = 3183.96[/tex]

[tex] = > h = \frac{3183.96 \times 3}{3.14 \times 13 \times 13 \times 1 } [/tex]

Point T has coordinates (-7, -3). If it's reflected across the line x = 2, what will be the coordinates of its image?

(7, -3)
(11, -3)
(7, 3)
(-7, 7)

Answers

Answer:

The answer would be (7,-3)

Step-by-step explanation:

If you use a graph and place the point (-7,-3) and draw the line x=2, you can see that x = 2 is a vertical line. If it is reflected across, you simply get (7,-3).

Given the proportional steel cost, how much do 200 pounds of steel cost?

Answers

Answer:

Your answer is B, 150

Step-by-step explanation:

If we look at the chart it says 160 pounds of steel is 120, so for example if we start from 40 we will have 30, so every time we add 40 pounds 30$ are added, meaning that 160+40=200, 120+30= 150, Thus B or 150 is our answer.

Answer:

$150

Step-by-step explanation:

Hi,

We know that 160Ibs of steel costs $120. To find the cost of 1Ib of steel, we have to divide both 160Ibs and $120 by 160. Here's what I mean...

Total amount: 160Ibs

Divide by 160...

Total amount: 1Ib

Total cost: $120

Divide by 160...

Total cost: $.75

That means that each pound of steel costs $.75

Now, multiply by 200 to get the total cost if you buy 200Ibs of steel...

200 x .75 = 150

The total cost would be $150

Hope this helps :)

What is distance between two points?

The distance between two points is the length of the line segment joining them.

Given that a coordinate plane, a rectangle has 4 points. Point W is (-5, 3), point X is (0, 3), point Y is (0, -1), and point Z is (-5, 0).

Distance between two points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Therefore,

XY = [tex]\sqrt{(0-0)^2+(-1-3)^2}[/tex]

XY = [tex]\sqrt{4^2}[/tex]

XY = 4

Hence, the length of side XY on the coordinate plane is 4 units.
