Answer:

This is a educated guess, but x is 80 and y is 100.

Step-by-step explanation:

My logic here is that the triangles are the same because of all the congruent lines and stuff. But from there, you know that both the right and the left side are 40 degrees. You know the total degree of a triangle is 180 so 180 - 40 - 40 is 100. So the final angle is 100. If you look at x, its on the outside, but on a line. If you can imagine a circle, its half, so its a 180 degrees total. Then its 180 = x + 100. So x is 80. And then by that same logic its y = 100.

Which linear equations has a slope of -3 and a y intercept of 4

Pavlova-9 [17]

This would be represented by the function Y = -3x + 4 C:

just remember that your slope is your X value, and on a graph it is your rise over run. since -3 is your slope, you go down -3(your rise, you go down since it is negative) and over one. its a whole number instead of a fraction because -3/1 is simplified to -3. Your Y intercept is the added number in the end of the equation. Basically they are your values in the linear equation, which is Y = mx + b

The diagonals of a rectangle measure x+5 feet and 2x+1 feet what is the value of x?

vodomira [7]

The value of x is 4.

Given that diagonals of a rectangle measure x+5 feet and 2x+1 feet as shown in the attached figure.

The diagonal of a rectangle is a line or straight line that connects the opposite corners or vertices of the rectangle.

In the given figure ABCD is a rectangle.

OA=2x+1 and OD=x+5 [Given]

AC and BD are diagonals of a rectangle.

As we know that the diagonals of a rectangle are always equal.

So, AC = BD

We can also write it as,

2×OA=2×OD

2×(2x+1) =2×(x+5)

Apply the distributive property a(b+c)=ab+ac, we get

4x+2=2x+10

Subtract 2x from both sides, we get

4x+2-2x=2x+10-2x

2x+2=10

Subtract 2 from both sides, we get

2x+2-2=10-2

2x=8

Divide both sides by 2, we get

2x/x=8/2

x=4

Hence, the value of x=4 when diagonals of a rectangle measure x+5 feet and 2x+1 feet.

Use this h=graph to graph x > 7

HACTEHA [7]

Btw I’m not 100% confident in this answer.

There is a open circle over 7 in the x-axis b cause it is not greater than and less than 7

A.y=-9/4x+47<br> B.y=-7/2x+59<br> C.y=-5x+69<br> D.y=-5x+80

Eduardwww [97]

Answer:

the answer is D

Step-by-step explanation:

just add the x into the equation. example→ -5(16)+80 =0. based on the graph the dot is on the true line so it make sense. i use x=16 based on the graph to get y. if x and y is match with the equation then thats was the answer. sorry if my answer is wrong.
