50 POINTS: The graph of a system of equations with the same slope will have no solutions. WITH EXPLINATION PLEASE

1 answer:

8 0

A system of two linear equations can be graphed as two lines.
The solution of the system of equations is a point that is part of both lines.
As a graph, you see two intersecting lines. The only point on both lines is the intersection of the lines. This is the solution of the system of equations.

Now think of two parallel lines. They never intersect. Parallel lines have the same slope. Since there is no point that is part of both lines, there is no solution to the system of equations.

How can you multiply positive and negative fractions?

Ivan

Step-by-step explanation:

When you multiply a fraction by another fraction or a fraction by a whole number, the rules of fractions dictate the form of the answer. If at least one of the values is negative, you also use the rules for positive and negative signs to determine if the result is positive or negative.

Answer:

Both Brittany and Sid are correct.

Step-by-step explanation:

Since both heights drawn would be equal to each other because they are the same triangle (but in different locations), the heights would equal each other.

In triangle RST, SQ=8 and QT=12. Find SW and UQ

Doss [256]

Given:

In triangle RST, SQ=8 and QT=12.

To find:

The measure of sides SW and UQ.

Solution:

We know that centroid of a triangle is the intersection point of the medians and it divides each median in 2:1.

In the given figure SW and TU are medians and Q is the centroid. So,

$\dfrac{SQ}{QW}=\dfrac{2}{1}$

$\dfrac{8}{QW}=\dfrac{2}{1}$

$\dfrac{8}{2}=QW$

$4=QW$

Now,

$SW=SQ+QW$

$SW=8+4$

$SW=12$

TU is a median. So,

$\dfrac{QT}{UQ}=\dfrac{2}{1}$

$\dfrac{12}{UQ}=\dfrac{2}{1}$

$\dfrac{12}{2}=UQ$

$6=UQ$

Therefore, the measure of SW is 12 units and the measure of UQ is 6 units.

Find the perimeter of -3x+4 2x+7

Alex787 [66]

Assuming that (-3x + 4) and (2x + 7) are two legs of a rectangle, you can find the perimeter like this: P = 2*length + 2*width.

P = 2*(-3x + 4) + 2*(2x + 7)
P = -6x + 8 + 4x + 14
P = -2x + 22

Hope this helps! :)

Answer: The answer is B.

Step-by-step explanation:

Angle ABC is a straight angle, which is 180 degrees, so you can rule out answers C and D.

For angle EBG, simply count the measures of the angle on the protractor. From the right, you start at 55. You end at 100. Subtract 55 from 100 to get a measure of 45 degrees.
