The value of b that makes the equation b * 4 = 12 true is b = 3. Thus, the correct answer is option (D).
Let's apply each option and see which value of b makes the equation b * 4 = 12 true:
A) b = 48
48 * 4 = 192 (not equal to 12)
B) b = 16
16 * 4 = 64 (not equal to 12)
C) b = 8
8 * 4 = 32 (not equal to 12)
D) b = 3
3 * 4 = 12 (equal to 12)
Therefore, the value of b that makes the equation b * 4 = 12 true is b = 3.
Thus, the correct answer is option (D).

Write a Linear Equation in
Point-Slope Form.
m = -5
(-3, – 7)
==================================
Work Shown:
m = -5 is the slope
(x1,y1) = (-3,-7) is the point the line goes through
Plug this into the point slope form below and simplify.
y - y1 = m(x - x1)
y - (-7) = -5(x - (-3))
y + 7 = -5(x + 3)
Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.

Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.
Answer:
y = 3/5x - 17/5
Step-by-step explanation:
slope formula: (y₂ - y₁) / (x₂ - x₁)
First, plug in these values of the two given points.
(-4 - (-1)) / (-1 - 4)
Simplify within the parentheses.
(-4 + 1) / (-1 - 4)
(-3) / (-5)
3/5
This is your slope. Plug this into a standard slope-intercept equation: y = mx + 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 (-1, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 3/5(-1) + b
Multiply.
-4 = -3/5 + b
Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.
-20/5 = -3/5 + b
-20/5 + 3/5 = b
-17/5 = b
Now, plug this into your standard equation.
y = 3/5x - 17/5
Check this equation by plugging in the other point you did not use (4, -1)
-1 = 3/5(4) - 17/5
-1 = 12/5 - 17/5
-1 = -5/5
-1 = -1
Your answer is correct!
Hope this helps!

Suppose a city with population 300,000 has been growing at a rate of 2% per year. If this rate continues, find the population of this city in 20 years
I need help solving this
Answer:
the answer is 445,784
Step-by-step explanation:
The population y after x years of growth with the growth rate r and the original population C can be found using the exponential growth formula, . Substitute the decimal equivalent for the percent growth rate per year for r.
Last month Albert earned half of what Betty earned, while Betty earned $5000 more than what Calvin earned. If Donna earned twice what Calvin earned and Albert and Betty together earned $900 more than what Calvin and Donna earned together, how much did each person earn?
Answer:
Calving earning = 4400
Betty earning = 9400
Albert earning = 4700
Donna = 8800
Step-by-step explanation:
Given that :
Calving earning = c
Betty earning = c + 5000
Albert earning = (c + 5000) /2
Donna = 2c
c + 5000 + (c + 5000) /2 = 900 + c + 2c
c + 5000 + 0.5c + 2500 = 900 + 3c
1.5c + 7500 = 900 + 3c
7500 - 900 = 3c - 1.5c
6600 = 1.5c
c = 6600 / 1.5
c = 4400
Calving earning = c = 4400
Betty earning = 4400 + 5000 = 9400
Albert earning = (4400 + 5000) /2 = 4700
Donna = 2(4400) = 8800

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2

Convert the equation `5x+2y=-8`into slope-intercept form.
Answer:
y= -2.5x-4
Step-by-step explanation:
we have to isolate our y
subtract 5x from 5x+2y=-8 and move it to the right side
2y= -5x-8
divide everything by 2
y=-2.5x-4

Kwame fills a bird feeder with seeds. As
birds visit the feeder, the height of the
seeds changes from 13.6 cm to 11.1 cm
over a period of 6 1/4 hours. What is the
average change in the height of the seeds
each hour?
Answer:
Step-by-step explanation:
Givens
Time = 6.25 hours
distance = 13.6 cm - 11.1 cm = 2.5 cm
Formula
rate = distance / time
Solution
rate = 2.5 / 6.25
rate = 0.4 cm/hour
