If three parallel lines are cut by a transversal and one angle is measured to be 90 degrees, what can be said of the remaining?

V125BC [204]

Answer: A. There all 90 degrees

Step-by-step explanation:

Given: Three parallel lines are cut by a transversal and one angle is measured to be 90 degrees.

We know that if two lines cut by transversal the following pairs are equal:

Vertically opposite angles.
Corresponding angles.
Alternate interior angles.
Alternate exterior angles.

If one angles measures 90°, then its supplement would be 90°.

Then by using above properties , we will get measure of all angles as 90°.

Vanessa has scored 45, 32, and 37 on her three math quizzes. She will take one more quiz and she wants a quiz average of at leas

zhenek [66]

45 + 32 + 37 = 114

114÷3 = 38

4 total quizzes,

for a 40 average on 4 quizzes she needs 40*4 = 160 total points

for 3 quizzes she has 45 +32 +37 = 114 points

160-114 = 46, she needs at least a 46 on the 4th quiz

The line above goes through points (-4,0) and (0,1). what is the equation of the line?

mariarad [96]

Answer:

y = $\frac{1}{4}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 1)

m = $\frac{1-0}{0+4}$ = $\frac{1}{4}$

Note the line crosses the y- axis at (0, 1) ⇒ c = 1

y = $\frac{1}{4}$ x + 1 ← equation of line

MAT1033 HELP ! 8x+12y=9

nadya68 [22]

Slope-Intercept form: y = mx + b, with m = slope and b = y-intercept

The easiest method to find the slope and y-intercept is to convert this standard form equation to slope-intercept form. Firstly, subtract 8x on both sides of the equation: $12y=-8x+9$

Next, divide both sides by 12, and your slope-intercept form is: $y=-\frac{2}{3}x+\frac{3}{4}$

Now looking at this slope-intercept form, we can see that the <u>slope is -2/3 and the y-intercept is (0, 3/4).</u>
