Answer:

300 can be expected to prefer spaghetti over meatloaf.

Answer:

Step-by-step explanation:

15:21 = x:420 (students that want da spaghetti:overall students)

cross multiply

15   x

21  420

6300=21x

divide by 21 on both sides

300=x

300 students out of the 420 prefer da spaghetti

Answer: I think the answer is b

Step-by-step explanation:

20% off means that there is 80% on which means you pay that 80% so you move the decimal point two spots

80.0% to .80 and multiply store a’s price of 59.99 to get 47.992 round the two in the decimal down making the total price for store a 47.99 and total price for store b 49.99 so store a is the better price by two dollars

6,000

Step-by-step explanation:

1,000*2=2,000

63/21=3

2,000*3=6,000

Answer:

3000

Step-by-step explanation:

21 hours x 3 = 63 hours

if the bacteria doubles every 21 hours, in 63 hours it would have doubled three times. 1,000 bacteria x 3 = 3,000 bacteria

Answer:

The error is the slope is -4 and the correct is, the slope is  [tex]-\frac{1}{4}[/tex]

Step-by-step explanation:

You must put the equation in the form of y = m x + b, where

Let us put the equation n the form above

∵ x = -4y

→ Switch the two sides

∴ -4y = x

→ Make the coefficient of y equal 1 by divide both sides by -4

∵ [tex]\frac{-4y}{-4}[/tex] = [tex]\frac{x}{-4}[/tex]

∴ y = [tex]\frac{x}{-4}[/tex]

→ Write [tex]\frac{x}{-4}[/tex] as [tex]-\frac{1}{4}[/tex] x

∴ y =  [tex]-\frac{1}{4}[/tex] x

→ Compare it by the form above

∴ m =  [tex]-\frac{1}{4}[/tex]  and b = 0

∴ The slope of the is  [tex]-\frac{1}{4}[/tex] , and the y-intercept is 0

∴ The error is the slope is -4 and the correct is the slope is  [tex]-\frac{1}{4}[/tex]

Answer:

C

Step-by-step explanation:

f = [tex]3^{x} + 10x\\[/tex]

g = 4x-2

f + g = [tex]3^{x} + 10x[/tex] + 4x-2

= C: [tex]3^{x} + 14x -2[/tex]

Answer:

3/5x - 21

Step-by-step explanation:

3/5x represents the three fifths of a number, and - 21 represents 21 less :)

The sequence 8, 6, 4, 2, ... diverges. It is a divergent sequence.

Divergent sequence is defined as the sequence whose limit does not exists or is infinite.

Here,

The sequence given is,

8, 6, 4, 2,..

The common difference of the sequence, d = 6 - 8 = -2

nth term of the sequence, aₙ = a + (n - 1)d

aₙ = 8 + (n - 1) x -2

aₙ = 8 + 2n - 2

aₙ = 2n + 6

Taking the limit of the sequence,

L = [tex]\lim_{n \to \infty} a_n[/tex]

L = [tex]\lim_{n \to \infty} (2n + 6)[/tex]

We get the limit of the sequence as infinite. So, the sequence is a divergent sequence.

Hence,

The sequence 8, 6, 4, 2, ... diverges.

Answer:  y = 2x + 14   x is the number of weeks. 14 (b) was his original performance in miles jogged per week. y is the expected performance.

Sketch attached.

Step-by-step explanation:  Given John's current performance, it is likely that he was able to jog some number of miles per week, the "b" in slope-intercept form.  To calculate:

30 = 2(8) + b

30 = 16 + b

30 - 16 = b

14 = b

Substitute into the slope intercept equation:

y = 2x + b

Answer:

f(b)=75%b

Answer:

Step-by-step explanation:

1. An equation is said to be linear if the variables have power not greater than 1.

Thus, the linear equations from the list are:

B. Y = [tex]\frac{2}{3}[/tex]x + 6

C. Y = |x| + 4

D .Y = 2x - 5

2. Comparing the equations with y = mx ± c, the constant rate of change for each linear equation are:

B. [tex]\frac{2}{3}[/tex]

C. 1

D. 2

3. The constant rate of change is the gradient (slope) of a linear equation. It describes the steepness of a line from the plot of points obtained from the linear equation.
