Answer:

The value of x is 12 and the value of y is 23. The given figure wrong because the vertically opposite angles are not same.

Step-by-step explanation:

From the given graph it is clear that lines XY and WZ intersect each other at point A and make 4 angles.

The angle XAZ and angle ZAY are supplementary angles because they lie on a straight line.

\angle XAZ+\angle ZAY=180

6x+35+8x-23=180

14x+12=180

14x=168

x=12

The value of x is 12.

The angle XAW and angle WAY are supplementary angles because they lie on a straight line.

\angle XAW+\angle WAY=180

3y+y+88=180

4y+88=180

4y=92

y=23

The value of y is 23.

The value of x is 12 and the value of y is 23, so the measure of all angles are

\angle XAZ=6x+35=6(12)+35=107

\angle ZAY=8x-23=8(12)-23=73

\angle XAW=3y=3(23)=69

\angle WAY=y+88=23+88=111

If two line intersect each other then the vertically opposite angles are always same. But here vertically opposite angles are not same.

\angle XAZ\neq \angle WAY

\angle ZAY\neq \angle XAW

Therefore the given figure wrong because the vertically opposite angles are not same.

Answer:

undefined

Step-by-step explanation:

since both points have a y value of ten the line is vertical, making the line undefined and therefore having no slope.

Andy joins a social networking site. After day three, he has 25 friends; after day eight, he has 40 friends. Write the equation
Allisa [31]

Answer:

Point slope intercept form: The equation for line is given by; y-y_1=m(x-x_1) ......[1] ; where m is the slope and a point (x_1, y_1) on the line.

Let x represents the number of days and y represents the number of friends.

As per the statement:  After day three, he has 25 friends; after day eight, he has 40 friends.

⇒ We have two points i.e,

(3, 25) and (8, 40)

First calculate slope(m);

m = \frac{y_2-y_1}{x_2-x_1}

Substitute the given values we get;

m = \frac{40-25}{8-3}=\frac{15}{5} = 3

now, substitute the given values of m=3 and a point (3, 25) in [1] we get;

y-25=3(x-3)

Using distributive property; a \cdot(b+c) = a\cdot b + a\cdot c

y-25 = 3x - 9

Add 25 on both sides, we get;

y-25+25 = 3x - 9+25

Simplify:

y =3x + 16

if  x = 18 days, then;

y = 3(18) + 16 = 54+16 = 70

Therefore, he will have on day 18, if he continues to add the same number of friends each day is, 70 friends.
