m ≤ -20

Step-by-step explanation:

-20and all the numbers less than -20 are a solution.  I know that -20 is included because the point on it is solid.  If the point was hollow the answer would be m < -20

The interest earned is $60 and the balance of the account is $460. The interest and the balance of the account will be both calculated with their given formulas.

An expense or payment for using borrowed money is interest; it is occasionally stated as a percentage of the principal borrowed. It could also be applied to the returns on investments or savings. Interest is the cost that a borrower typically reimburses a lender for the use of their funds.

A. We must use the formula-

Interest = Principal x Rate x Time, to calculate the interest earned.

Here, Interest = $400 divided by 0.03 and multiplied by 5.

Earned interest is $60.

B. We must utilize the formula-

Balance = Principal + Interest, to determine the account's balance.

Balance = $400 + computed interest in this instance.

Balance: $400 + $60.

The account's balance is $460.

74 meters

Step-by-step explanation:

The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.

2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.

Step-by-step explanation:

Answer:Therefore, the percent change from 56 to 77 students is 37.5%.

Step-by-step explanation:

students, we can use the following formula:

percent change = ((new number - old number) / old number) x 100%

Plugging in the values given in the problem, we get:

percent change = ((77 - 56) / 56) x 100%

percent change = (21 / 56) x 100%

percent change = 0.375 x 100%

percent change = 37.5%

Therefore, the percent change from 56 to 77 students is 37.5%.

C. -6.1, -6 4/9, 6.3..., 630%

Step-by-step explanation:

-6.1 in mixed number form is -6 1/10, making it greater than -6 4/9. This is because, if the numbers were positive, -6 4/9 would be greater than -6.1, but since the numbers are negative, it's opposite.

Therefore, the answer is:

C. -6.1, -6 4/9, 6.3..., 630%

Answer:

x = 47

Step-by-step explanation:

We need to solve for the interior angle measure x. To get x, we know that the sum of the triangles angle measures are 180, so lets write an equation to find x.

[tex]x+102+31=180[/tex]

Add like terms

[tex]x+133=180[/tex]

Subtract 133 on both sides

[tex]x=47[/tex]

To check our work, we can add the angle measures together so we know we got it right.

[tex]47+102+31=180[/tex]

Answer:

x=48

Step-by-step explanation:

add 102 and 31 then subtract it by 180

Answer:

2: (2, 0)

Step-by-step explanation:

Since 2 is x and 0 is y, you would put those numbers in the equation. These 2 numbers work for both equations so it is the correct answer.

Answer: Option 2 - (2,0)

Step-by-step explanation:

By substituting the values of x and y only option 2 is appropriate for the equation to be true.

Answer:

y = -4x + 13

Step-by-step explanation:

y = mx + b

We need the slope (m) which was given to us: -4

We need to find the y-intercept (b)

We will use the point given (2,5) and the slope to find b.

y = 5   from the point (2,5)

x = 2   from the point (2,5)

m = -4  given

substitute these into the equation

y =mx + b

5 = (-4)2 + b

5 = -8 + b   Add 8 to both sides

5 + 8 = -8 + 8 + b

13 = b

We now know that m is -4 and b is 13.  Write the equation

y = mx + b

y = -4x + 13

Answer:

M = 2

Step-by-step explanation:

Equivalence means to be same, whether it be value, temperature, size, etc.

If equivalence means to be the same, we can use this equation to figure out what M is equal to.

So, in order to solve for M, we need to divide 6.5 by 3.25.

Therefore, M = 2.

Answer:

A. y = 2x + 0 B. The slope of the equation is 2, which means that for every 2 eggs, you need 4 cups of flour. C. For 8 eggs, you would need 16 cups of flour.

Answer: 16 cups of flour

Step-by-step explanation:

As amount of flour is directly proportional to number of eggs,

2/4 = 8/y

y = 8*4/2 = 16

Answer:

152 grams of zinc

Step-by-step explanation:

You can always first create some ratios to clean it up

[tex] \frac{zinc}{copper} = \frac{4}{19} = \frac{x}{722} [/tex]

x being zinc, what we need to find

Next we can cross multiply

[tex]19x = (722)(4)[/tex]

[tex]19x = 2888[/tex]

Lastly, we will divide both sides by 19 to get X alone.

[tex]x = 152[/tex]

Answer:

Step-by-step explanation:

the answer would be D

we can rewrite the function as F(y) = y^2. notice that this function is written as F(y) rather than F(x). if this were a function of y we would write it as F(x)= squareroot(x)

the difference between a function of x and a function of Y is that in a Function of x the x value will be isolated and in a function of y the y value will be isolated.

Answer: 1. 432

2. 36              3.136

Step-by-step explanation:

The linear regression equation that represents this set of data is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is given as follows:

39.46.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points for this problem are given as follows:

(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).

Inserting these points into a calculator, the equation is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:

31 = 1.05x - 10.43

x = 41.43/1.05

x = 39.46.
