Solve the equation

3s-4s=28

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

Answer: he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)

Step-by-step explanation:

We know that Tim bought all of the two 3/4 lb packages for a party.

Then he bought 2 packages. Such that each package has  3/4 lb meat.

Then the total amount of meat that Tim has is equal to 2 times the amount of meat in each package, this is:

Total meat = 2*(3/4 lb) = (6/4 lb)

and we can write 6 = 4 + 2

then:

Total meat =  6/4  lb = (4 + 2)/4  lb = (4/4 + 2/4) lb = (1 + 1/2) lb

So he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)

Answer:

C:Acute traingle

Acute traingle

I know this triangle is equilateral and acute, but I'm not sure what the third choice would be.

Answer:

slope is 0

y-(-8)=0(x-(-2))

y+8=0(x+2) no solution

Step-by-step explanation:

[tex]\frac{-8-(-8)}{8-(-2)} =0/10[/tex]

Answer:

1/2 or 0.5

Step-by-step explanation:

so to find the slope of two points you use the slope formula which is rise over run, y2-y1/x2-x1. so that would be -1-0/7-9. leading to -1/-2. so the slope is 1/2 or 0.5.

Answer:

He would need to get a minimum of 28 questions correct.

Step-by-step explanation:

92% of 30 is 27.6 but you cant really get .6 of a question right, so you would need to round. Which makes it 28.

I'll focus on problem 19 and problem 22

============================================================

Problem 19

Answers:

-------------------------------

Explanation:

The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.

Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.

x+15 = 102

x = 102-15

x = 87

Which leads to

x+15 = 87+15 = 102

============================================================

Problem 22

Answer: y = 27

-------------------------------

Explanation:

We have a pair of alternate exterior angles. They are congruent due to the parallel lines.

Let's solve for y.

7y-55 = 3y+53

7y - 3y = 53+55

4y = 108

y = 108/4

y = 27

Answer:

$5193.77

Step-by-step explanation:

You want to figure out what x is.

Since x is the number of years after 1996, you can do 2005 - 1996 = 9 years.

Then, plug x = 9 into the equation:

y = 11,000(0.92)^9

Plug this into a calculator and you get: y = $5193.77

Answer:

m=48

Step-by-step explanation:

m/3=18-2

m/3=16

m=16x3

m=48

Answer:

m=48

Step-by-step explanation:

Subtract 2 from both sides

2+m/3-2=18-2

Simplify

m/3=16

Multiply both sides by 3

3m/3=16*3

simplify

m=48

Answer:

[tex]220[/tex] cm

Step-by-step explanation:

We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be [tex]2(l+w)[/tex], where [tex]l[/tex] is the rectangle's length and [tex]w[/tex] is the rectangle's width. We are given that [tex]l=70[/tex] and [tex]w=40[/tex]. Therefore, [tex]2(70+40)=2*110=220[/tex] cm of ribbon will be needed. Hope this helps!

Answer:

Its red becasue 1/2 is greater than all of them

The most likely color of the marble that will be chosen is red.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Number of red marbles in the bag=1/2

Number of blue marbles in the bag=1/4

Number of green marbles in the bag=1/6

Number of yellow marbles in the bag=1/12

Now,

To determine the most likely color of the marble that will be chosen, we need to calculate the probability of selecting each color. The probability of selecting a red marble is 1/2, the probability of selecting a blue marble is 1/4, the probability of selecting a green marble is 1/6, and the probability of selecting a yellow marble is 1/12.

To compare the probabilities, we need to find a common denominator. The common denominator for 2, 4, 6, and 12 is 12. So, we can rewrite the probabilities as:

Probability of selecting a red marble = 6/12

Probability of selecting a blue marble = 3/12

Probability of selecting a green marble = 2/12

Probability of selecting a yellow marble = 1/12

Since the probability of selecting a red marble is the highest among all the colors, it is the most likely color to be chosen.

Therefore, by probability the answer will be red marble.

Answer:

The 75th term of the arithmetic sequence -17, -13, -9.... is:

[tex]a_{75}=279[/tex]

Step-by-step explanation:

Given the sequence

[tex]-17, -13, -9....[/tex]

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]-13-\left(-17\right)=4,\:\quad \:-9-\left(-13\right)=4[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=4[/tex]

The first element of the sequence is:

[tex]a_1=-17[/tex]

now substitute [tex]d=4[/tex] and [tex]a_1=-17[/tex] in the nth term of the sequence

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=4\left(n-1\right)-17[/tex]

[tex]a_n=4n-21[/tex]

Now, substitute n = 75 in the [tex]a_n=4n-21[/tex] sequence to determine the 75th sequence

[tex]a_n=4n-21[/tex]

[tex]a_{75}=4\left(75\right)-21[/tex]

[tex]a_{75}=300-21[/tex]

[tex]a_{75}=279[/tex]

Therefore,  the 75th term of the arithmetic sequence -17, -13, -9.... is:

[tex]a_{75}=279[/tex]
