Find the slope of the line that passes through (7,5) and (4, 9)

Answers

Answer:

-4/3

Step-by-step explanation:

(9-5)/(4-7)

4/-3

-4/3

Write an
equation of the line that passes through each pair of points.
(-3,9), (-3,-5)

Answers

Answer:

since slope(m) = y2 -y1/x2- x1

-5 - 9/ -3 - (-3)= -14/0

m = -14/0 (undefined)

using the formula

y-y1 = m(x -x1)

y - 9 = -14/0(x - (-3)

y-9 = -14/0(x + 3)

0 = -14( x+3). (cross multiplication)

0 = -14x - 42

14x = -42

x = -3( equation of the line)

Find the distance Between points (3,7) and (-3,4).

Answers

Answer:

the distance is 3√5 !

Step-by-step explanation:

Answer:

Since the points form a triangle, you can use Pythagorean theorem to solve this.

Side A is 3 Units, and side B is 6. The letters do not matter when corresponding them to the sides.

So Pyth Theorem = a^2 + b^2 = c^2

And c^2 is the distance we must find

So a^2 = 9

b^2 = 36

So 36 + 9 = 45

To find C, you must root c^2

So sqrt of 45 is 6.7

The distance between points (3,7) and (-3,4) is 6.7 units.

Answer:

  p = 1.2

Step-by-step explanation:

From here, it is a 2-step linear equation.

Step 1:

Identify the constant term on the side of the equation with the variable. Subtract that constant from both sides.

  -10.9p = -13.08

Step 2:

Divide both sides by the coefficient of the variable.

  p = -13.08/-10.9 = 1.2

The solution is p = 1.2.

Step-by-step explanation:

The top is a square 3 cm by 3 cm.

The other 4 sides are rectangles. Each one is 4 cm by 3 cm.

Front: 4 cm * 3 cm = 12 cm^2

Back: 4 cm * 3 cm = 12 cm^2

Right: 4 cm * 3 cm = 12 cm^2

Left: 4 cm * 3 cm = 12 cm^2

Top: 3 cm * 3 cm = 9 cm^2

TOTAL: 12 cm^2 + 12 cm^2 + 12 cm^2 + 12 cm^2 + 9 cm^2

TOTAL: 57 cm^2

Bottom prism (blue):

Front: 5 cm * 6 cm = 30 cm^2

Back: 5 cm * 6 cm = 30 cm^2

Right: 5 cm * 6 cm = 30 cm^2

Left: 5 cm * 6 cm = 30 cm^2

Bottom: 5 cm * 5 cm = 25 cm^2

Top: 5 cm * 5 cm - 3 cm * 3 cm = 25 cm^2 - 9 cm^2 = 16 cm^2

TOTAL: 30 cm^2 + 30 cm^2 + 30 cm^2 + 30 cm^2 + 25 cm^2 + 16 cm^2

TOTAL: 161 cm^2

Explanation for area of top of bottom (blue) prism.

Notice that the entire bottom of the top (yellow) prism is connected to the bottom prism, so there is no area of the bottom of the top prism that adds to the total surface area of the composite solid. With the bottom prism's top surface it is different. Since the top surface of the blue prism is larger than the bottom surface of the yellow prism, there is a bit of top surface of the blue prism that is seen. That area is the area of the top surface of the blue prism minus the area of the bottom surface of the top prism.

5 cm * 5 cm = 3 cm * 3 cm = 25 cm^2 - 9 cm^2 = 16 cm^2

The area of the top surface of the blue prism is 16 cm^2

Total surface area of the composite solid:

57 cm^2 + 161 cm^2 = 218 cm^2

Answer:

57 cm^2

Step-by-step explanation:

4 (4x3) + (3x3) = 48 + 9 = 57 cm^2

Front: 12 cm2

Back: 12 cm^2

Right: 12 cm^2

Left: 12 cm2

Top: 9 cm^2

Answers

9514 1404 393

Answer:

  (d)  51 miles per hour

Step-by-step explanation:

The constant of proportionality can be found by dividing the distance by the time. It is convenient to choose a time that makes this division simple. We choose 30 min = 1/2 hour.

  (25.5 mi)/(1/2 h) = 2(25.5) mi/h = 51 mi/h

The constant of proportionality is 51 miles per hour.

Step-by-step explanation:

The negation of a statement is almost like the opposite, but it needs to cover all cases that the statement does not.

1) x is not equal to 300.

This statement is true for all x except 300 while our original statement is true for all x except 100. These two have overlaps between what values of x could be, meaning that it is not the negation.

2) x is equal to 100.

This statement is true only for the case x equals 100 while our original statement is true for all the cases where x is not 100. These two do not overlap and cover all numbers. This means that it is the negation.

3) It is not the case that x is equal to 400.

This statement is true for all x except 400 while our original statement is true for all x except 100. These two have overlaps between what values of x could be, meaning that it is not the negation.

4) x is equal to 300.

This statement is true only for the case x equals 300 while our original statement is true for all the cases where x is not 100. This two cases have overlaps(300), meaning it is not the negation.

Aaron's car used 3- gallons of gas when
he drove it 60 miles. How many miles
does his car get per gallon?

Answers

We want to find miles per gallon. Another way of saying miles per gallon is miles/gallon. So we will plug the numbers into this equation:

60 miles/3 gallons = 20 miles/gallon

This is because 60/3=20.

I hope this makes sense.

Answer:

His car gets 20 miles per gallon.

Step-by-step explanation:

1. 60 = 3x (divide by 3)

2. 20 = x

Therefore, the car uses 20 miles per gallon.

The answer to this question is -1.75

Answer:

The value of the expression is 0.5.

Step-by-step explanation:

To evaluate, we need to do order of operations.

To solve, we start with the parenthesis because they come first in the order of operations.

-1+3[(10-12)³/(-16)]

-1+3[-2³/-16]

Now we do the second thing in the order of operations, which is to simplify the exponents.

-1+3[-8/-16]

Now we do the third thing left to do, which is to do division and multiplication from left to right.

-1+3[0.5]

-1+1.5

Now we do the last thing left to do, which is to do addition and subtraction from left to right.

0.5

So the value of this expression is 0.5.

Decreasing on the interval(s) [tex]-1\leq y\leq 1[/tex]

Step-by-step explanation:

Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.

The increasing interval of the graph is -3

The decreasing interval of the graph is 0.5

Since the values are in the middle of the interval, it automatically becomes the answer.
