<h2>Answer:</h2>

The statements which are true about the given lines are:

A. Line 4y = −16 is horizontal.

B. Line 3x = 27 is vertical.

D. For either line, one of the coordinates of all the points is always the same value.

<h2>Step-by-step explanation:</h2>

We have two lines as:

4y = −16 and 3x = 27

i.e. y= -4 and x=9

Now, we know that the first line i.e. y= -4 is a straight horizontal lines and the coordinate of the points on these lines are of the type: (x,-4)

The second line: x=9 is a straight vertical line and the coordinate of the points on these lines are of the type: (9,y)

Hence, we get that for either of these lines one of the coordinate of all the points is always the same.

I need help with this question, pls put step by step

Scrat [10]

Answer:

150 degrees and 30 degrees

Step-by-step explanation:

Let's say the measure of the angle is x. This angle is 5 times that of its supplementary, supplementary angles will add up to 180 degrees. So we have an equation of x = 5(180-x). Solve this equation for x

x = 5(180-x)

x = 900 - 5x

6x = 900

x = 150 degrees, this is the value of one angle

The other angle is 180-x = 180-150 = 30 degrees

A parking attendant charges a different rate for cars than for trucks. It costs $10.75 to park 3 cars and 2 trucks. It costs $12

timurjin [86]

Answer:

$1.25 to park a car and $3.50 to park a truck

Step-by-step explanation:

Set up a system where c is the number of cars parked and t is the number of trucks:

3c + 2t = 10.75

7c + t = 12.25

Solve by elimination by multiplying the bottom equation by -2 to eliminate t:

3c + 2t = 10.75

-14c - 2t = -24.5

Add them together and solve for c:

-11c = -13.75

c = 1.25

Then, plug in 1.25 as c in the equation to solve for t:

3c + 2t = 10.75

3(1.25) + 2t = 10.75

3.75 + 2t = 10.75

2t = 7

t = 3.5

So, it costs $1.25 to park a car and it costs $3.50 to park a truck

6 cm<br> 6 cm<br> What is the area?

AnnyKZ [126]

Answer:

= 18 $cm^{2}$

Step-by-step explanation:

As the triangle is right angled:

formula

= $\frac{1}{2}$ base x height

= $\frac{1}{2}$ 6 x 6

= $\frac{1}{2}$ x 36

= $\frac{36}{2}$

= 18 $cm^{2}$
