Answer:

slope = 4

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 )

y = - 5 + 4x, that is

y = 4x - 5 ← is in slope- intercept form

with slope m = 4

HELP, <br> Would I have to subtract 180 from 70 to get the answer for C?? What would the answer be?

Setler79 [48]

Answer:

<em>Angle C is equal to 30.</em>

Step-by-step explanation:

To find angle C, we have to find all the other angles first. They tells us the B ~= BAD ~= ADC. So, if we find ADC, we've found B and BAD as well. ADC is just 180 - 70 (the angle of ADE), which is 110. So, ADC, BAD, and B are equal to 110.

Remember, angles in a quadrilateral add up to 360. So, add all of the values of angles be have now and subtract from 360:

360 - (110 + 110 + 110)

360 - 330 = 30

Angle C should be equal to 30.

Hope this helped!

Find slope for 2x+5y=8?

Nitella [24]

First thing, you need to transform this equation to the form of y = ax + b

So you get:
2x + 5y = 8
5y = -2x + 8
$y = -\frac{2}{5} x + \frac{8}{5}$

In the form of y = ax + b, a is the slope.
In $y = -\frac{2}{5} x + \frac{8}{5}$ , you can see " $- \frac{2}{5} x$ ", and always the number before x is the slope
So, the slope of 2x + 5y = 8 is $- \frac{2}{5}$

Hope this Helps :)

A student studying his classmates' cars' ages reports the 5-number summary as {1, 3, 4, 8, 20}. what is the iqr for his data?

timurjin [86]

IQR for the data {1, 3, 4, 8, 20} is 5.

Interquartile Range(IQR) for a data is defined as the difference between third quartile and first quartile.

denoted by IQR=Q₃-Q₁ (Q₃ is third quartile and Q₁ is first quartile)

The five number summary of a data set is represented as

{minimum, first quartile , second quartile , third quartile , maximum}..…(1)

According to the question

{1, 3, 4, 8, 20}

On comparing it with equation …(1)

minimum=1

Q₁ =3 , Q₂=4 , Q₃=8 , maximum =20

IQR=Q₃-Q₁

Substituting the values we get

IQR=8-3=5.

Therefore , Interquartile Range for the data {1, 3, 4, 8, 20} is 5.
