Pachacha [2.7K]3 years ago
4 0

Answer:

5/2

Step-by-step explanation:

the equatino you are using is point slope form which is an equation involving the points and the slope and the origonal equation is y-y1=m(x-x1) m standing for slope, and x1 and y1 standing for the first coordinates, so the slope would be 5/2

If someone can do both I’d appreciate it! I’ve been up for awhile trying to fingers these out.
Lilit [14]

Answer:

3. AGH= 150

4. CHF= 110

Step-by-step explanation:

3. AGH corresponds to CHF, so they equal the same. AGH = 150

4. BGE is vertical to AGH, so they equal the same AGH = 110. AGH corresponds to CHF, so they equal the same. CHF=110.

Which expression shows the distance on the number line between −12 and 8?
makkiz [27]

Answer: The answer for this would be the rise over run. If you know what the rise over run expression is great. If not, here it is. The slope of a non-vertical line is the ratio of the amount it rises over some interval, over the length of that interval.

It is written like this rise/run.

Step-by-step explanation: Start from 8 and RISE (vertically) 4 places, the RUN (horizontally) and count until you get to -12. Then you take your numbers and divide.

How do I express the following as a fractional part of a year?
timama [110]

Answer:

See below.

Step-by-step explanation:

A year has 12 months and 365 days.

3 months: 3/12 year = 1/4 year

55 days: 55/365 year = 11/73 year

1 month: 1/12 year

7 months = 7/12 year

120 days = 120/365 year = 24/73 year

G(x) = x - 2x^2<br><br>g(-1)
Goshia [24]
(-3).
We plug (-1) for x in g(x) and we get:
(-1) - 2(-1)^2.
To simplify, (-1)^2 turns to just 1. since a negative times a negative gives a positive.
Then, we have (-1) - 2(1) or (-1) - 2 or -1 - 2.
This is then -3

10. Polygon WXYZ has vertices W(-1.5, 1.5),
vovikov84 [41]

Answer:

See explanation

Step-by-step explanation:

Polygon WXYZ has vertices W(-1.5, 1.5), X(6, 1.5), Y(6, -4.5), and Z(-1.5, -4.5).

Find the slopes of all sides:

WX:\ \dfrac{1.5-1.5}{6-(-1.5)}=\dfrac{0}{7.5}=0 - horizontal line

XY:\ \dfrac{-4.5-1.5}{6-6}=\dfrac{-6}{0} - slope undefined, so the line is vertical

YZ:\ \dfrac{-4.5-(-4.5)}{-1.5-6}=\dfrac{0}{-7.5}=0 - horizontal line

ZW:\ \dfrac{1.5-(-4.5)}{-1.5-(-1.5)}=\dfrac{6}{0} - slope undefined, so the line is vertical

Vertical and horizontal lines are perpendicular, so all angles W, X, Y and Z are right angles. Hence, quadrilateral WXYZ is a rectangle
