Answer:

y= -7x + 35

Step-by-step explanation:

(y - 7) = -7(x - 4)

y-7 = -7x + 28

y = -7x + 35

Answer:

40 minutes

Step-by-step explanation:

there are 60 min in an hour. 60/3= 20. That Is 1/3 of an hour. 20*2= 40. That is 2/3 of an hour.

Answer: 280 children

Explanation: Each grade has 70 kids. You have 4 total grades (3rd, 4th, 5th, and 6th grade). You have to add the number of kids you have in every grade. In this case, 70 children in 3rd grade, 70 children in 4th grade, 70 children in 5th grade, and 70 children in 6th grade. The problem would look like this:

70 + 70 + 70 + 70

Then your answer is 280 when you add them all together!

Answer:

[tex]\frac{8}{52}[/tex] = 0.15384615384 = 15.38%

Step-by-step explanation:

There are 4 7s and 4 queens so

[tex]\frac{4}{52}[/tex] + [tex]\frac{4}{52}[/tex] = [tex]\frac{8}{52}[/tex]

This expression is not factorable with rational numbers

Answer:

y = -5/3x + 13/3

Step-by-step explanation:

(-1, 6) and (5, -4).

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-4 - 6) / (5 - (-1))

Simplify the parentheses.

= (-10) / (5 + 1)

= (-10) / (6)

Simplify the fraction.

-10/6

= -5/3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -5/3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (5, -4). Plug in the x and y values into the x and y of the standard equation.

-4 = -5/3(5) + b

To find b, multiply the slope and the input of x(5).

-4 = -25/3 + b

Now, add 25/3 to both sides to isolate b.

-4 ⇒ -12/3

-12/3 + 25/3 = 13/3

13/3 = b

Plug this into your standard equation.

y = -5/3x + 13/3

This is your equation.

Check this by plugging in the other point you have not checked yet (-1, 6).

y = -5/3x + 13/3

6 = -5/3(-1) + 13/3

6 = 5/3 + 13/3

6 = 18/3

6 = 6

Your equation is correct.

Hope this helps!

Answer:

This is false.  (1, 10) is not a solution of this inequality

Step-by-step explanation:

Copy down the inequality:

y < 8x + 2

Now substitute 10 for y and 1 for x:

10 < 8(1) + 2  or 10 < 8 + 2

This is false.  (1, 10) is not a solution of this inequality

Answer:

False is the answer.

Answer:

20 students

Step-by-step explanation:

You first have to add the number of students all up and you get 200.Then you do cross multiplication.

40/200 x s/100=

40x100= 4000=

200xs= 200s=

200s/200=

4000/200=

20=

Answer: Part-to-part

Step-by-step explanation:

This is a part-to-part, because they show part of apples, and part of oranges. This ratio when set up is 4:3. If the ratio was part-to-whole, then the apples would be compared to the total amount of oranges and apples. The ratio for part-to-whole would be 4:7.

Hope this helps!

Answer:

y=3x/2 -8

Step-by-step explanation:

2y/2 = 3x/2 + 10/2

y = 3x/2 +5

(y-(-5)) = 3/2 (x-2)

y+5 = 3x/2 - 3

y= 3x/2 - 8

Answer:

40

Step-by-step explanation:

5 × 8 = 40

1 × 40 = 40

2 × 20 = 40

Answer:4/8 or simplified answer 1/2

Step-by-step explanation:

3/4 + 3/8, first you have to find the highest common factor of 4 and 8.

The answer is 9. The denominator of both side will be 8. Now you ask yourself 4 times what gives you 8 and times the numerator by that number. And do the same for the 8.

6/8 + 3/8= 9/8

9/8 - 5/8= 4/8

The simplified answer is 1/2

Answer:

Step-by-step explanation:

Answer:88

Step-by-step explanation:

1.10c+2.35s=294.20

C+S=172

1.10c+2.35s=294.20 if you multiply by 100.

110c+235s=29420

-110 (cones + sundaes =172)

-110c-110s=-18920

125s/125=10500/125

S= 84

C+84=172

-84. -84

C= 88

Answer:

C

Step-by-step explanation:

Answer:

I am not sure but I think it is C

Step-by-step explanation:

This can be MULTIPLE answers but C seems right. Because this is a square, basically all these answers are right, so the question is worded incorrectly

x=17

Skewed Right I think. I'm not sure but try it

Answer:

C. Skewed Left

Step-by-step explanation:

Because the first 2 age group have minimal runners than the next 3 age groups spikes and the last 4 are very low once again. the spike occurs relavity near the beggining so if graphed it would be skewed left.

Answer:

Step-by-step explanation:

Im guessing its telling you to solve using substitution ?

Well your lucky, most of the work is already done :D

you know y=x-7 , so just replace y with (x - 7) in the other equation

4x - 7(x-7) = 10

4x - 7x + 49 = 10

-3x = -39

x = 13

Now just plug X in the original equation to fine Y

y = x - 7

y = 13 - 7

y = 6

so the solution would be

(13,6)
