Which of the following is a solution to the equation: y = 7x + -59? Choose all that apply.
Select all that apply:
O (8,-3)
O (9,8)
O (7,-3)
0 (10,5)

Answers

Answer 1

Answer:

[tex](a)\ (8,-3)[/tex]

Step-by-step explanation:

Given

[tex]y =7x +-59[/tex]

Required

Select all solutions

[tex](a)\ (8,-3)[/tex]

This implies that:

[tex]x = 8; y=-3[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]-3 =7 * 8 + -59[/tex]

[tex]-3 =7 * 8 -59[/tex]

[tex]-3 =56 -59[/tex]

[tex]-3 =-3[/tex]

The above is a solution:

[tex](b)\ (9,8)[/tex]

This implies that:

[tex]x=9\ y =8[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]8 =7 * 9 + -59[/tex]

[tex]8 =7 * 9 -59[/tex]

[tex]8 =63 -59[/tex]

[tex]8 =4[/tex]

The above is not a solution because [tex]8 \ne 4[/tex]

[tex](c)\ (7,-3)[/tex]

This implies that:

[tex]x=7;\ y=-3[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]-3 = 7 * 7 +-59[/tex]

[tex]-3 = 7 * 7 -59[/tex]

[tex]-3 = 49 -59[/tex]

[tex]-3 = -10[/tex]

The above is not a solution because [tex]-3\ne -10[/tex]

[tex](d)\ (10,5)[/tex]

This implies that:

[tex]x =10; y=5[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]5 = 7 * 10 + -59[/tex]

[tex]5 = 7 * 10 -59[/tex]

[tex]5 = 70 -59[/tex]

[tex]5 = 11[/tex]

The above is not a solution because [tex]5 \ne 11[/tex]

Write 3 equivalent ratios for each ratio given.
6.25 to 1.25

Answers

Answer:

3 equivalent ratios are: [tex]\frac{62.5}{12.5}, \frac{625}{125}, 5[/tex]

Step-by-step explanation:

Ratio of a to b:

The ratio of a to b is given by:

[tex]\frac{a}{b}[/tex]

Finding equivalent ratios:

To find equivalent ratios, we multiply or divide both a and b by the same value.

6.25 to 1.25

[tex]\frac{6.25}{1.25}*\frac{10}{10} = \frac{6.25*10}{1.25*10} = \frac{62.5}{12.5}[/tex]

[tex]\frac{6.25}{1.25}*\frac{100}{100} = \frac{6.25*100}{1.25*100} = \frac{625}{125}[/tex]

[tex]\frac{\frac{6.25}{1.25}}{{\frac{1.25}{1.25}}} = 5[/tex]

3 equivalent ratios are: [tex]\frac{62.5}{12.5}, \frac{625}{125}, 5[/tex]

The population of China was about 1.39 billion in the year 2013with an annual growth rate of about 0.6\% . Find an equation P(t) that represents the growth function for China. Write your answer in the form a * (b) ^ 2 in billions Provide your answer below:

Answers

Answer: 1.39(1.006)^t

Step-by-step explanation:

The equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.

What is a Function ?

A statement that relates two unknown parameters such that one is dependent on the other is called a function.

It is given that

Initial population = 1.39 billion in 2013

Growth Rate = 0.6%

Let a represent the initial population

b is the growth rate

and 2 be the elapsed year from 2013

and let the population at any given year is P(t)

Then the equation formed is

P(t) = a * bⁿ

P(t) = 1.39 * ( 1.006)ⁿ

Therefore the equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.

Juan has four ties, three shirts and four pairs of pants. How many different outfits can he wear if he chooses one Tie, one shirt, one pair of pants of each outfit?

Answers

Answer:

48 outfits

Step-by-step explanation:

Using Fundamental Principal of counting

number of outfits that Juan can wear

=number of ties * number of pants * numberof pants

=4*3*4

=48 outfits

The number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.

What is the combination?

The arrangement of different things or numbers in a number of ways is called a combination.

A permutation is an orderly arrangement of things or numbers. Combinations are a way to choose items or numbers from a collection or group of items without worrying about the items' chronological order.

Given that Juan has four ties, three shirts, and four pairs of pants.

Using the Fundamental Principle of counting,

Number of outfits that Juan can wear

N =number of ties x number of pants x number of pants

N =4 x 3 x 4

N =48 outfits

Therefore, the number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.

-2x - 9y = -3
--7x - 9y = -33

Answers

Answer:

x = 6 and y = -1

Step-by-step explanation:

hope this helps

Answer:

x= 6 and y= -1

Step-by-step explanation:

-2x - 9y = -3

-7x - 9y = -33

I'm going to be solving by elimination. However, you can solve using substitution as well.

So the first step is to eliminate one of the variables. In my opinion, what's easiest is eliminating the y variables. To eliminate you want to variables (that are the same) to equal 0 and cancel out. To do this, all I have to do is subtract. When I subtract I get 0 as shown below. I will also subtract the other variables and numbers in the equations because that's how elimination works.

-2x - 9y = -3

-7x - 9y = -33

5x = 30

-2 - (-7)=5 and -3 - (-33)= 30

There's no solution for the y variable because -9 - (-9)=0, which cancels out so it doesn't have to be written.

after that you get x=6 because you divide by 5 on both sides.

All that's left is to plug in 6 to one of the equations:

-2(6) - 9y= -3

-12 - 9y= -3

+12         +12

-9y= 9

Divide both sides by -9 to get y= -1

If a quadrilateral has these known angle degrees: 35, 35 and 145, what are the degrees of the fourth angle?

Step-by-step explanation:

The total sum of all the angles is 360 degrees. If we add up 35, 35, and 145 we get 215. 360-215=145.

A positive angle less than 360 that is coterminal with -725 degrees is

Answers

The angles number would be 230

The positive angle is less than 360 which is coterminal with -725 degrees is  85 degrees.

What are Coterminal Angles?

Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.

An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.

To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.

In this case, -725 degrees - (2 x 360) = -725-720= -1445.

So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.
