Find the slope of the line that passes through the two points below."
(7,-1) and (9,0)

Answer:

A general line is written as:

y = a*x + b

where:

a is the slope

b is the y-intercept.

a) y-intercept = 2 and slope = 7.

This line is:

y = 7*x + 2

b) y-intercept =  -1 and is parallel to y= 5x - 7.

Now, if two linear equations are parallel if they have the same slope and different y-intercept. Then if we want a line parallel to  y= 5x - 7, this means that the slope of this line must also be equal to 5.

y = 5*x + (-1)

c) y-intercept 2 and is inclined at 45° to the x- axis. ​

When we have an inclination of A degrees from the x-axis, the slope of the equation is given by: a = Tan(A)

In this case, we have A = 45°

Then the slope is a = Tan(45°) =  1

Then the equation of this line is:

y = 1*x + 2

Q

Step-by-step explanation:

X has constant value

x'-x = 0

m =(y'-y)/(x'-x)  --> undefined

Answer:

R

Step-by-step explanation:

A vertical line has a slope that is "undefined". Line R is the vertical line on your graph

___________

The slope of a vertical line is "undefined" because of the way slope is defined. Slope is the vertical change divided by the horizontal change. When the line is vertical, there is no horizontal change, so the computation of slope involves division by zero. The result of division by zero is "undefined."

Answer:

28 gallons.

Step-by-step explanation:

1/5 is 20% of the container's full capatcity.

7/10 is 70% of the container's full capatcity.

20% - 70% = 50%

By adding 14 gallons of water, the container's water went up by 50%.

If we multiply 14 by 2, we will know what the container can hold at 100% capatcity.

14 x 2 = 28

In this exercise we have to use knowledge of direction and congruent lines to identify which objects have these characteristics, so we can say that:

Rectangular Prism

Cube

Cylinder

Triangular pyramid

First we have to remember the definition of congruent lines, such as:

Answer: 20.77%

Step-by-step explanation:

There are 52 cards in a standard deck. Out of these cards, there are 12 face cards. Thus, the probability of drawing a face is 12/52.

On a 20-sided dice, there are 20 options of numbers to roll. Out of these 20 numbers, 18 of the numbers are greater than or equal to 3, making the probability 18/20, or 9/10.

To find the probability of two events, you need to multiply the probabilities together. Thus, you need to multiply 12/52 by 9/10.

(12/52) * (9/10) = 27/130

27/130 is about equal to 0.2077, or a 20.77% probability.

Answer:10000

Step-by-step explanation:

Remember that log x and 10^x are inverse functions.

If you have log x = 4 and want the value of x, write this out:

log x 4

10 = 10

This simplifies to:

x = 10^4, and so the fourth answer choice is the correct one.

Answer:

We are given

We are also given  and , which allows us to rewrite the equation as

(I substituted every "b" with "a" and every "c" with "9").

The solutions to this quadratic equation are -25 and 7. We discard -25 because a side with negative length would make no sense.

The required measure of side a of the rectangular prism is a = 9.3 meters.

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
SA = 2ab + 2bc + 2ac
434 = 2a² + 14a + 14a
434 = 2a² + 28a
2a² + 28a - 434 = 0
a² + 14a - 217 = 0
a² + 14a + 49 - 49 - 217 = 0
(a + 7)² = 266
a = 9.3 or a = -23.3

Since the negative measure of length can be neglected.
a = 9.3 = b

Thus, the required measure of side a of the rectangular prism is a = 9.3 meters.

#SPJ5

Answer:

a) SPAZ is equilateral.

b) Diagonals SA and PZ are perpendicular to each other.

c) Diagonals SA and PZ bisect each other.

Step-by-step explanation:

At first we form the triangle with the help of a graphing tool and whose result is attached below. It seems to be a paralellogram.

a) If figure is equilateral, then SP = PA = AZ = ZS:

[tex]SP = \sqrt{[4-(-4)]^{2}+[(-2)-(-4)]^{2}}[/tex]

[tex]SP \approx 8.246[/tex]

[tex]PA = \sqrt{(6-4)^{2}+[6-(-2)]^{2}}[/tex]

[tex]PA \approx 8.246[/tex]

[tex]AZ =\sqrt{(-2-6)^{2}+(4-6)^{2}}[/tex]

[tex]AZ \approx 8.246[/tex]

[tex]ZS = \sqrt{[-4-(-2)]^{2}+(-4-4)^{2}}[/tex]

[tex]ZS \approx 8.246[/tex]

Therefore, SPAZ is equilateral.

b) We use the slope formula to determine the inclination of diagonals SA and PZ:

[tex]m_{SA} = \frac{6-(-4)}{6-(-4)}[/tex]

[tex]m_{SA} = 1[/tex]

[tex]m_{PZ} = \frac{4-(-2)}{-2-4}[/tex]

[tex]m_{PZ} = -1[/tex]

Since [tex]m_{SA}\cdot m_{PZ} = -1[/tex], diagonals SA and PZ are perpendicular to each other.

c) The diagonals bisect each other if and only if both have the same midpoint. Now we proceed to determine the midpoints of each diagonal:

[tex]M_{SA} = \frac{1}{2}\cdot S(x,y) + \frac{1}{2}\cdot A(x,y)[/tex]

[tex]M_{SA} = \frac{1}{2}\cdot (-4,-4)+\frac{1}{2}\cdot (6,6)[/tex]

[tex]M_{SA} = (-2,-2)+(3,3)[/tex]

[tex]M_{SA} = (1,1)[/tex]

[tex]M_{PZ} = \frac{1}{2}\cdot P(x,y) + \frac{1}{2}\cdot Z(x,y)[/tex]

[tex]M_{PZ} = \frac{1}{2}\cdot (4,-2)+\frac{1}{2}\cdot (-2,4)[/tex]

[tex]M_{PZ} = (2,-1)+(-1,2)[/tex]

[tex]M_{PZ} = (1,1)[/tex]

Then, the diagonals SA and PZ bisect each other.

Answer:

4 dollars a pound

Step-by-step explanation:

4x 10 = 40

Step-by-step explanation:

Use the compound interest formula:

A = P( 1 + r/n)^nt

A is the amount at the end

P is the principal or original amount.

R is annual rate as a decimal (you have to convert)

N is the # of compounding periods in a year (quarterly means 4)

T is time in years

A = 500( 1 + 0.0475/4)^(4×20)

This would be $1285.64 when fully computed.

Answer:

2 Pumpkins / 15 Dollars

5 Pumpkins / 37.5 Dollars

10 Pumpkins / 75 Dollars

Step-by-step explanation:

2 pumpkins for 15 dollars

that is what we have to work with here

the first step would probably be to figure out how much one pumpkin is, so we should divide the amount that we spent by the amount of pumkins that we got, which would look like

15 / 2 = 7.5

so 1 pumpkin = 7.5 dollars

now, to figure out how many pumpkins you can buy with 37.5 dollars, you would divide the amount of money spent by the amount that each pumpkin costs, which turns out to be

37.5 / 7.5 = 5

Now, to figure out how much money you would need for 10 pumpkins, you would multiply the number of pumpkins by the cost of a single pumpkin, which ends up being

10 x 7.5 = 75
