So, we see side AB, and side BC.

(Don't look at AB as a straight line like this, imagine it slanted if you want to)

If the slope is -3, and the intersection of AB and BC make a perpendicular, then a slope of [tex]\frac{1}{3}[/tex] would cause the right angle to form.

So, [tex]\frac{1}{3}[/tex] is the slope of BC.

Answer:

4x + 4 or (2x) + (2x+4)

Step-by-step explanation:

Ok so east is the right side. The length of the east side would be (2x) + (2x+4). You can then simplify this to 4x + 4 but I don't know if your teacher wants you to do that. Hope this helps!

Answer:

A. 6.63 centimeters

B. 57.8 gallons

Step-by-step explanation:

26.5/4=6.625

6.625=6.63

6.63 centimeters

37*24*15=13320

13320/230.4

57.8125=57.8

57.8 gallons

Answer:

see below

Step-by-step explanation:

6y = 12x + 26

15y = 45x + 60

First let's simplify these equations.

6y = 12x + 26

Divide each term by 6.

y = 2x + 26/6

Simplify the fraction.

26/6

= 13/3

Your simplified equation is:

y = 2x + 13/3

Let's simplify the other equation.

15y = 45x + 60

Divide each term by 15.

y = 3x + 4

These are your simplified equations.

y = 2x + 13/3

y = 3x + 4

We can see that the slope of the first equation is not equal to the slope of the second equation.

The y-intercept of the first equation is not equal to the y-intercept of the second equation.

Now we want to solve the equations.

Both equations are equal to y, so you can set them equal to each other.

2x + 13/3 = 3x + 4

Combine like terms.

1/3 = x

Plug x = 1/3 into both of the equations separately..

y = 2(1/3) + 13/3

y = 2/3 + 13/3

y = 15/3

y = 5

y = 3(1/3) + 4

y = 3/3 + 4

y = 1 + 4

y = 5

Your solution is (1/3, 5)

The system of equations has one solution.

Answer:

13 days

Step-by-step explanation:

Protein powder in container = 16 oz

Number of containers = 5

Total ounces of protein powder = (16 * 5) = 80 oz

Oz of protein used per shake = 2 oz

Number of times shake is made per day = 3

Total oz used per day = 2 oz * 3 = 6 oz

Number of days hencan make all three shakes from container :

Total ounces / ounces per day

80 oz / 6 oz

= 13. 33 days

Answer:

y=8x+25

y=5x+12

Step-by-step explanation:

To write a system of equations you must write an equation for both plan A and B. For plan A, the 25 dollars is the constant because it is only paid once. The 8 dollars must be multiplied by the variable x because it is paid each month. These added together will equal the total cost or y. In plan B the 12 dollars is the constant and 5 is being multiplied by the variable.

Answer:

C would be your answer

Step-by-step explanation:

The hourly rate for Kira by mowing her neighbor's lawn is $7/hour.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

Kira earned $7 mowing her neighbor's lawn for an hour.

So,

$7 ⇒ 1 hour

So $7/hour will be the hourly rate.

Hence "The hourly rate for Kira by mowing her neighbor's lawn is $7/hour".

Step-by-step explanation:

Let the present age of father = x years

and the present age of son = y years

according to the first condition

x + y =44 ........(i)

according to the second condition

x+8 = 2(y+8)

or x+ 8 = 2y + 16

or x- 2y = 8 ............(ii)

solve the equation (i) & (ii) we get

x + y =44

x- 2y = 8

••••••••••••••••••••••••

3y = 36

or y = 12

put the value of y in equation (i), we get

x + 12 =44

or x = 32

so the present age of father = x =32 years

and the present age of son = y = 12 years.

Answer:

b)

x = 3 hotdogs

y = 7 hamburgers

Step-by-step explanation:

Steve went to the concession stand and bought hamburgers and hot dogs for the kids he brought to watch a baseball game. Each child chose either one hamburger or one hotdog. Hot dogs cost $1.50 each and hamburgers cost $2.75 each. Steve spent a total of $23.75 on 10 kids.

(a) Could Steve have bought an equal amount of hamburgers and hot dogs? Justify your answer.

An

(b) If x represents the number of hotdogs purchased and y represents the number of hamburgers purchased, write a system of equations that models this situation and determine the number of both items bought.

Let:

x = the number of hotdogs purchased y = the number of hamburgers purchased

Since the number of kids = 10

Our system for Equation is given as:

x + y = 10...... Equation 1

x = 10 - y

x × $1.50 + y × $2.75 = $23.75

1.5x + 2.75y = 23.75

Let us substitute 10 - y for x in Equation 2

1.5(10 - y) + 2.75 = 23.75

15 - 1.5y + 2.75y = 23.75

- 1.5y + 2.75y = 23.75 - 15

1.25y = 8.75

y = 8.75/1.25

y = 7 hamburgers

Solving for x

x = 10 - y

x = 10 - 7

x = 3 hotdogs

Therefore,

x = 3 hotdogs

y = 7 hamburgers

Answer:

61°

Step-by-step explanation:

We have many angles and are asked to find angle number 4.

Looking at the picture, if we take a look at the angle across (mirrored) from 4, we see that it lists being 61 degrees, since that angle is a complete mirror of angle 4. Angle number 4 is 61°

Answer:

the answer is 59

Step-by-step explanation:

a circle is 360 degrees, which means half of a circle is 180. This means the angles that are along ray q must add up to 180. if you add the 2 known angles

60+61

you can subtract that from 180

180 - (60+61)= measure angle 4

180 - 121 = measure angle 4

180 - 121 = 59

Answer: B.

Step-by-step explanation:

Quadrants in the Coordinate Plane

The coordinate plane is divided into 4 quadrants named I, II, III, and IV as shown in the image attached below.

The first quadrant (I) has the x positive and the y positive

The second quadrant (II) has the x negative and the y positive

The third quadrant (III) has the x negative and the y negative

The fourth quadrant (IV) has the x positive and the y negative.

A point located in quadrant III must have both coordinates negative. This only corresponds to choice B where both components are negative.
