Use the information to find an equation (y=mx+b) for the amount of Sponsorship money (Y) you an make for each day of the trip. Show your work and explain your steps below. Coca Cola 5 days - $134 10 days - $164 15 days - $194 20 days - $224

Answers

Answer:

y = 6x + 104

Step-by-step explanation:

Given the equation in the form:

y = mx + b

m = slope ; b = intercept

Given the data:

5 days - $134 10 days - $164 15 days - $194 20 days - $224

To obtain the slope, Pick the points :

(5, 134) and (20, 224)

Slope = y2 - y1 / x2 - x1

Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6

Plugging into the equation :

We have ;

y = 6x + b

Picking any point from the data and plugging in to solve for b:

(10, 164)

164 = 6(10) + b

164 = 60 + b

b = 164 - 60

b = 104

Equation finally becomes ;

y = 6x + 104

7(x-4)=4x+5 whats X?

Answers

Answer:

x = 11

Step-by-step explanation:

In this question, you would solve for x.

Solve for x:

7(x - 4) = 4x + 5

Use the distributive property.

7x - 28 = 4x + 5

Subtract both sides by 4x.

3x - 28 = 5

Add 28 to both sides.

3x = 33

Divide both sides by 3.

x = 11

Your final answer would be x = 11

Answer:

x=11

Step-by-step explanation:

First, do the parentheses (PEMDAS).

7(x-4)=4x+5 to 7x-28=4x+5

Then, add 28 to either side to get all the numbers on one side.

7x-28=4x+5 to 7x=4x+33

After that, subtract 4x to get all the x's on one side.

7x=4x+33 to 3x=33

Finally, divide by 3 to get your final answer.

3x=33 to x=11

Tell whether the ratios form a proportion. 30/75, 24/60

Answers

Given:

The ratios are  [tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex].

To find:

Whether the ratios form a proportion or not.

Solution:

If two ratios represent the same relationship then they form a proportion.

We have,

[tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex]

Write the given ratios in the simplified forms.

[tex]\dfrac{30}{75}=\dfrac{15\times 2}{15\times 5}[/tex]

[tex]\dfrac{30}{75}=\dfrac{2}{5}[/tex]

And,

[tex]\dfrac{24}{60}=\dfrac{12\times 2}{12\times 5}[/tex]

[tex]\dfrac{24}{60}=\dfrac{2}{5}[/tex]

Since [tex]\dfrac{30}{75}=\dfrac{24}{60}=\dfrac{2}{5}[/tex], therefore the ratios form a proportion.

Solve for r.

–6(r − 98) = 78

Answers

Answer:

r = 85

Step-by-step explanation:

→ -6 ( r - 98 ) = 78→ r - 98 = -13→ r = -13 + 98→ r = 85

conclusion:

so the value of r is 85

Step-by-step explanation:

First, divide both sides of the equation by -6.

-6(r-98)÷6=78÷6

This gives us r-98=-13

Then, add 98 to both sides.

r-98+98=-13+98

The answer is r=85

Tamara says she used the GCF to factor the expression 21x + 56xy as 7(3x + 8xy). Is she correct? Explain.
please write the correct answer

Answers

Answer:

Tamara incorrectly factored the whole expression.

Step-by-step explanation:

Note that

•21x=3·7·x;

•56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

There is a bag with 50 popsicles inside. 5
are red, 15 are orange, 12 are blue, 8 are
yellow and 10 are purple. If you were to
grab one popsicle from the bag, what is
the probability that it is purple?

Answers

Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

Find the measure of angle 1

Answers

Answer:

112 degrees

Step-by-step explanation:

Since the two sides opposite of angle 1 and 2 are congruent, as shown by the double tic marks, the angles are conguent. The total sum of all angles must be 360 degrees, so we know 90 degrees was given, as well as 46 degrees. That's 136 degrees together, subtract that from 360 and you get 224. Angles 1 and 2 are congruent so both add to 224, therefore each angle is 112 degrees.

Please help, thank you.

The question is in the picture

Answers

Answer:

C. a= 4, b= 2

Step-by-step explanation:

In a parallelogram, opposite sides are equal.

So, 4a+1 = 2a+9

On solving, we get, a= 4

Similarly, 6b= 11b-10

On solving, we get, b= 2

Answer:

answer: option C: a=4,b=2

explanation:

opposite sides of a parallelogram are equal so,

QP =RS

6b=11b-10

I. e 6b-11b = -10

I. e. -5b = -10

I. e. - b = -10/2

I. e -b = -2

by removing minus sign from both the sides...

b =2

again opposite sides of a parallelogram are equal so,

QR =PS

4a + 1 = 2a + 9

I. e 4a- 2a = 9 - 1

I. e 2a = 8

I. e a = 8/2

therefore a= 4

so the answer is a=4 and b= 2
