Answer:
-2x - 7y = -13. X intercepts = (13/2,0)
3x+6y=15. Y intercept = (0,13/7)
Step-by-step explanation:
-2x-7y=-13. To find x intercept substitute 0 for y and solve for x.
3x+6y=15. To find y intercept substitute 0 for x and solve for y.

PLZ HELP WILL GIVE BRANLYIST! Why are the solutions to the proportions StartFraction 40 over 8 EndFraction = StartFraction x over 10 EndFraction and StartFraction x over 40 EndFraction = StartFraction 10 over 8 EndFraction the same? because both result in the equation 8 x = 400, which simplifies to x = 5 because both result in the equation 8 x = 400, which simplifies to x = 50 because both result in the equation 40 x = 80, which simplifies to x = 2 because both result in the equation 40 x = 80, which simplifies to x = 20
Answer:
Because both result in the equation 8x = 400 which simplifies to 50.
Step-by-step explanation:
If you cross multiply both of the pairs, you will get 8x = 400.
divide 400 by 8 to simplify and you get 50

It would be B.

Idk how to solve triangular prisms
Answer:
The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the left) times the height,h.
Step-by-step explanation:
hope that make sense, i tried to find something that explained
Step-by-step explanation:
Surface area is found by adding up all the areas of the different figures. When there are multiple figures of the same dimensions, you can just multiply them by the number of their amount.
The areas you'll be using for the triangular prism are:
[tex]a = \frac{1}{2} bh[/tex]
and
[tex]a = lw[/tex]
since there are both rectangles and triangles in this figure.
Using the prism, then, it's time to make a formula.
[tex]2( \frac{1}{2} bh) + 2(lw) + lw[/tex]
I put a 2 in front of the triangle's area because there are 2 triangles in this prism.
There's a 2 in front of the side of the triangle's area (it's a rectangle) because it has two sides.
That last lw doesn't have a number on it because it's for the base, and this prism only has one base.
Now, use the dimensions that are given to you to substitute.
[tex]2( \frac{1}{2} )(14)(24) + 2(10)(25) + (10)(14) \\ 336 + 500 + 140 \\ 836 + 140 \\ 976[/tex]
So, 976cm^2 is your area.
Answer:
[tex]976 {cm}^{2} [/tex]

Write the linear equation in the slope-intercept form when m=1 and b=-12
Answer:
y = x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = 1 and b = - 12 , thus
y = x - 12 ← equation of line
Felix drew two box-and-whisker plots to compare the same sets of data: In the form of a paragraph, use complete sentences to describe some of the differences in the prices of the two sets of books. Refer to the box and whisker plots to justify your answer.
Answer:
The first set of data shows that the difference in the prices is very small while the second set of data shows a larger variety of prices. The first set represents its prices in equally divided groups making it easier to read and determine than the second set of data.

3m^2-3n^2/6m-6n
ANSWER ASAP
Answer:
3.
Step-by-step explanation:
3m^2-3n^2= 3(m^2-n^2) = 3 (m+n)(m-n)
6m-6n= 6 (m-n)
3(m+n)~(m-n)~/6~(m-n)~ = (m+n)/2

The ratio of the measures of the angles of a triangle is 4:6:8. Find the measure of the largest angle.
Largest angle?
Answer:
80°
Step-by-step explanation:
The angles can be written as 4x, 6x, and 8x. Since the sum of angles in a triangle is 180 degrees we can write:
4x + 6x + 8x = 180
18x = 180
x = 10 which means the largest angle (8x) = 8 * 10 = 80°
Draw an ordered stem and leaf diagram to show this information.
3, 8, 12, 12, 14, 20, 21, 23, 26, 34
Im not really sure how to explain it but the number at the top of the ‘stem’ side has to be the smallest number and the bottom one is the biggest.
You then have to write out the numbers in the ‘leaf’ side by only putting one digit numbers in order from smallest to biggest.

Lucy graphed the equation x+9y=5 and 4x+15y=-1 and saw that they intersected at the point (-4,1) as shown. What can Lucy conclude? A. (-4,1) is a solution to the system of linear equations. B.(-1,4) is a solution to the system of linear equations. C. (1,-4) is a solution to the system of linear equations. D. (4,-1) is a solution to the system of linear equations.
Answer:
Option A.
Step-by-step explanation:
If a system of equations has two equations and the graph of both equations intersect at point, then the intersection point is the solution of the system of equations.
The given equations are
[tex]x+9y=5[/tex]
[tex]4x+15y=-1[/tex]
It is given that the graph of both lines intersect each other at point (-4,1).
It means, (-4,1) is a solution to the system of linear equations.
Therefore, the correct option is A.

which system of linear equations is represented by the graph?
Answer:
y ≥ x - 2, and x + 2y < 4 ; Option C
Step-by-step explanation:
Consider the y - intercept and slope of 1 of these given lines,
[tex]y - intercept = ( 0, - 2 ) / - 2\\slope = 1 / 1 = 1[/tex]
From this we can formulate the equation of 1 line;
[tex]Take Equation In the Form - y = ax + b, a - slope, and , b - y intercept,\\y = ax + b, a = 1, b = - 2,\\Equation of Line 1 - y = x - 2[/tex]
Now consider the y - intercept and slope of the remaining line;
[tex]y - intercept = ( 0, 2 ) / 2\\slope = 1 / - 2 = - \frac{ 1 }{ 2 }[/tex]
This creates a line with the equation as such;
[tex]Take Equation In the Form - y = ax + b, a - slope, and , b - y intercept,\\y = ax + b, a = - 1 / 2, b = 2,\\Equation of Line 1 - y = - \frac{ 1 }{ 2 } x + 2, x + 2y = 4[/tex]
From this we see that the solution of the system is such;
Solution ; y ≥ x - 2, and x + 2y < 4 ; Option C
