Answer:

Yes

Step-by-step explanation:

substitute the ordered pair into ya equation.

7x + y = y - 7; (-1,7)

7(-1) + 7 = 7 -7

multiply 7 and -1, add 7 and -7

-7 + 7 = 0

add -7 and 7

0 = 0.

So yes, the ordered pair (-1, 7) works in this equation

What is parallel to y=5x-5 ?
larisa [96]
Parallel lines are lines that exist in the same plane and never cross. In order to not cross, their slopes must be the same.

The line given is in slope-intercept form

y = mx + b
Where m is the slope and b is the y-intercept. Therefore the slope of the line y = 5x - 5 is 5.

Any line with a slope of 5 will be parallel.

For example, y = 5x + 1

Can someone explain to me how to solve problem 32?
krok68 [10]
Ok so parallel equations mean they have equal slope, but different y intercepts. Here, we can solve and get the equation:

y=2/5x-7/5

If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Helga [31]
Hello!

To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.

y=4(0)-1
y=-1

So here, an ordered pair could be (0,-1)

We can try this again for different x-values.

y=4(1)-1
y=3

This gives us the ordered pair  (1,3)

y=4(100)-1
y=399

This would give us the ordered pair (100,399)

I hope this helps!

Answer:

\text{1. }\triangle IJH\cong \triangle LKM, \\\text{2. }\triangle RST\cong \triangle YXZ, \\\text{3a. Reflexive Property}, \\\text{3b. ASA (Angle-Side-Angle)}

Step-by-step explanation:

ASA (Angle-Side-Angle) is a proof of congruence that states if two triangles share two angles and the side between those two angles, the triangles are congruent. In problems 1 and 2, the following demonstrate this:

\text{1. }\triangle IJH\cong \triangle LKM, \\\text{2. }\triangle RST\cong \triangle YXZ

In problem 3, \overline{IJ}\cong \overline{IJ} is known in geometry as the Reflexive Property. Because of this, the two triangles in the diagram for problem 3 now share two angles and the side between them, thus they are congruent from ASA (Angle-Side-Angle).
