Answer:

y = -1/4x - 1

Step-by-step explanation:

The equation of a line is y = slope*x + y-intercept

Find the slope by picking two points shown on the graph and doing (y1-y2)/(x1-x2): (4, -2) & (-8, 1) = (-2-1)/(4-(-8) = -3/12 = -1/4 so the slope is 4.

Find the y-intercept by seeing where the line crosses the y-axis: y= -1

So therefore, y = -1/4x - 1

For an earth day project, Rushdi collected 7 5/8 pounds of recyclables, Lydia collected 9 2/3 pounds of recyclables, and Latrell

Naddik [55]

Answer:

28 1/24 pounds

Step-by-step explanation:

Collected recyclables:

Rushdi = 7 5/8 pounds

Lydia = 9 2/3 pounds

Latrelle = 10 3/4 pounds

Total amount of recyclables collected :

(7 5/8 + 9 2/3 + 10 3/4) pounds

(61/8 + 29/3 + 43/4) pounds

L. C. M = 24

(183 + 232 + 258) / 24

673 / 24

= 28 1/24 pounds of recyclables.

The radius of a circle is 5.1 yards, what's the circles area?

balandron [24]

Answer: 26.01 pi

Step-by-step explanation: The formulae to find the area of a circle is pi times the radius squared. So 5.1 times 5.1=26.01. So the answer would be 26.01pi or (using 3.14 for pi) 81.6714

Write an equation of the line that passes through the given points: (9/2,1), (-7/2,7) please show step by step how to do this. T

Viktor [21]

Explanation:

The easiest way to do this is to make use of the 2-point form of the equation for a line. For points (x₁, y₁) and (x₂, y₂), the equation is ...

$y=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)+y_1$

Filling in your given points, the equation becomes ...

$y=\dfrac{7-1}{\frac{-7}{2}-\frac{9}{2}}(x-\frac{9}{2})+1$

After you fill in the values, it is a matter of simplifying the resulting equation.

$y=\dfrac{6}{\frac{-16}{2}}(x-\frac{9}{2})+1=\dfrac{-12}{16}(x-\frac{9}{2})+1=-\dfrac{3}{4}x+\left(\dfrac{-3}{4}\cdot\dfrac{-9}{2}\right)+1\\\\y=-\dfrac{3}{4}x+\dfrac{27+8}{8}\\\\y=-\dfrac{3}{4}x+\dfrac{35}{8}$

One of the same side angles of two parallel lines is 20° smaller than the other one. Find all angles. Please explain this proble

butalik [34]

When you have parallel lines same side interior angles add up to 180 degrees.
Let the first SSI (same side interior) angle be x, and the other SSI be (x - 20).
Therefore, x + (x - 20) = 180
2x - 20 = 180
add 20 to both side
2x = 200
divide both sides by 2
x = 100
x - 20 = 100 - 20 = 80
