Answer:

x = z = 70°

y = 110°

Step-by-step explanation:

From the diagram, we have 4 angles;

To find y;

110° and y are vertically opposite angles so they are equal.

So, y = 110°

Also, y and x lie on a straight line. Sum of angles on a straight line is 180°;

y + x = 180

110 + x = 180

x = 180-110 = 70°

Also, x and z are vertically opposite angles and they are equal;

x = z = 70°

y = 110°

Find the slope of the line passing through (-7,-8) and (5,-8)

zhenek [66]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (5, - 8)

m = $\frac{-8+8}{5+7}$ = $\frac{0}{12}$ = 0

Please help which of the following statements could be a function?

iragen [17]

Answer:

The first one height vs shoe size.

Step-by-step explanation:

Let's evaluate each choice

1) Generally, it is possible that the taller a person is, that his/her shoe size would generally get bigger also. Hence we can say that it is possible that there is a function correlation between height and shoe size.

2) hair length can be cut down short or left long regardless of the height of a person, so we cannot say for sure that hair length correlates with height. Hence this is probably not a function)

3) hair color has no bearing on a persons age. hence this is probably not a function.

4) student ID number doesn't depend on the name of the student. Hence this is probably not a function.

A woman drives an SUV that gets 12 mi/gal (mph). Her husband drives a hybrid that gets 55 mph.Every week, they travel the same n

a_sh-v [17]

Answer:

Option 2 gives a better combined mileage.

Step-by-step explanation:

Data provided in the question:

Mileage of SUV = 12 mi/gal

Mileage of hybrid = 55 mph or 55 mi/gal

After tuning the SUV, new mileage = 12 + 1 = 13 mi/gal

Now,

For Option 1:

Average mileage of SUV and the Hybrid = $\frac{13+55}{2}$

= 34 mi/gal

For Option 2:

Mileage of new car = 80 mph or 80 mi/gal

Average mileage = $\frac{12+80}{2}$

= 46 mi/gal

Hence,

Option 2 gives a better combined mileage.
