Answer:
A. The coefficients of z are the same, but the constant terms are different.
Step By step Explanation:
2(z – 1) = 4(z + 5)
Step 1: Simplify both sides of the equation.
2(z−1)=4(z+5)
(2)(z)+(2)(−1)=(4)(z)+(4)(5)(Distribute)
2z+−2=4z+20
2z−2=4z+20
Step 2: Subtract 4z from both sides.
2z−2−4z=4z+20−4z
−2z−2=20
Step 3: Add 2 to both sides.
−2z−2+2=20+2
−2z=22
Step 4: Divide both sides by -2.
−2z/−2 = 22/−2
z=−11
The coefficients for z are the same, but the constants are different.

There is a population of 1,000 bacteria in a colony. If the number of bacteria doubles every 21 hours, what will the population be 63 hours from now?
Answer:
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

A. Y=x^2+3 B. Y=2/3x+6 C. Y=|x|+4 D .Y=2x-5 1. Identify the linear equations from the list. 2. State the constant rate of change for each linear equation. 3. Briefly describe the relationship between constant rate of change and linear equations.
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.

Out of the 21 students in Terry's class, 15 prefer spaghetti over meatloaf. There are 420 students in Terry's middle school. Based on these survey results, how many students at Terry's school could be expected to prefer spaghetti over meatloaf?
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

Store A is selling clothes for 20% off. Store B advertises low prices without needing to give sales. A coat you want is sold at both places.
Store A's normal price is $59.99 plus 20% off. Store B's price is $49.99. Which store sells the coat the cheapest and by how much?
A.
Store B by $2.
B.
Store A by $2
C.
Store B by $4
D.
Store A by $4
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

Does the sequence 8, 6, 4, 2, ... converge or diverge ?
The sequence 8, 6, 4, 2, ... diverges. It is a divergent sequence.
What is meant by 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.

Describe and correct the error in finding the slope and the y-intercept of the graph of the equation.
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
m is the slope b is the y-interceptLet 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: 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
