Describe how the graph of y = |x| – 4 is like the graph of y = |x| and how it is different.
A. The graphs are the same shape. The y-intercept of y = |x| is 0 and the x-intercept of y = |x| – 4 is –4.
B. The graphs have the same y-intercept. The graph of y = |x| – 4 is steeper than y = |x|.
C. The graphs are the same shape. The y-intercept of y = |x| is 0 and the y-intercept oof y = |x| – 4 is –4.
D. The graph of y = |x| – 4 is the same as y = |x|.
Answer:
D. The graph of y = |x| – 4 is the same as y = |x|.
Step-by-step explanation:
The graph y=|x|-4 is obtained from the graph y=|x| dy moving down 4 units the graph y=|x| along the y-axis (see, if x=0, then for y=|x|, y=0 and for y=|x|-4, y=-4).
These two graphs have the same form.

Find the width of a rectangle with an area of 13 3/4 square feet and a length of 5 1/2 ft
Answer:
2.6
Step-by-step explanation:
Could you mark this the brainlist
Answer:
2.5 or 2 1/2 ft is the width
Step-by-step explanation:
Area of rectangle = length × width
(13 3/4 can also be written as 13.75)
(5 1/2 can also be written as 5.5)
Area = l × w
13.75 = 5.5 × w
13.75 ÷ 5.5 = w
2.5 = w

This graph represents −3x+y=−4. Which ordered pair is in the solution set of −3x+y≥−4?
Answer: When an inequality shows a multiple of -4 = -8 or -16 then we know it is a parallel line and therefore could be a straight line continuation - we see -3(1) -(5) = -8 and -3(5) -(1) = -16 therefore (1 -5) and (5 -1) are both ordered pairs
-3 (2) + 2 = -4 shows 2 and 2 are an ordered pair of system -3 (0) -4 = -4 shows 0 and -4 is an ordered pair of the system
Step-by-step explanation:
-3x + y = - 4 when we +3x both sides we get y = 3x - 4 so when y intercept starts in -4 we an assume if x is positive and as x is top heavy and not equal to 1 we have a fraction x = (y + 4) / 3 and the only thing we hanged to find this fraction value for x was to eliminate 3 and separate x through dividing by x to see other coordinates see attachment for ordered pairs by seeing each coordinate on the graph

Which best describes the type of triangle?
Answer:
the answer is obtuse. B. I hope this helps you!
Answer:
it is obtuse
Step-by-step explanation:
what is the y intercept of the line that passes through the point 3, 4 and has a slope of 3
(0, -5)
Step-by-step explanation:
Since we are given the slope and a point on the line, we can use these to write the point-slope form of the equation of the line, which looks this this:
[tex]y - y_1 = m(x - x_1)[/tex]
where [tex](x_1, y_1)[/tex] is the point on the line and m is the slope. So the equation has the form
[tex]y - 4 = 3(x - 3)[/tex]
To find the y-intercept, set x = 0 to get
[tex]y - 4 = 3(0 - 3) \Rightarrow y - 4 = -9[/tex]
Solving for y, we get
[tex]y = -5[/tex]
Therefore, the coordinates of the y-intercept is (0, -5).

What is quotient and product rule of logarithm?Logarithm, the exponent or power to which a base must be raised to yield a given number. The quotient rule says that, the logarithm of a quotient is equal to a difference & the product rule says that logarithm of product is equal to the sum of logarithm.
here, we have,
given that,
2 In e^(ln 5x) = 2 In 15
now, we have to solve it for x.
we know that,
e^(ln 5x) = 5x
using the rule of logarithm.
so, we have,
2 In (5x) = 2 In 15
now, for solving,
comparing both sides, we get,
15 = 5x
i.e. x = 15/5
or, x = 3
Hence, The solution is, the value of x = 3.

A paper airplane was thrown from the top of a tall building.The height of the paper airplane above the ground can be found using the function `y=-1.5x+60` , where `x` is the time in seconds the airplane has been in the air.
Jayden made this table to figure out how high the plane was at different times.
0 | 60
10 | 45
20 | 30
30 | 15
40 | 0
How would the equation `y=-1.5x+60` change if the height at 0 seconds was 75?
The new equation will be [tex]y=-1.5x+75[/tex]
Since the height at 0 seconds will be 75, it means that 15 has been added to the height at each time instant.
As a result, the gradient will remain [tex]-1.5[/tex], but the y-intercept will become 75. Therefore the equation will only change at the intercept.
The new equation will be [tex]y=-1.5x+75[/tex]

Answer:
130 degrees
Step-by-step explanation:
A triangles angles have to equal 180 degrees
A right angle = 90 degrees

180-130=50
A straight angle has to equal 180 degrees
180-50=130

1. A sample of bacteria cells in a petri dish increases by 50% every hour. A scientist
starts with a sample of 30 bacteria cells. Write an equation that can be used to
determine the number of cells after x hours.
2. how many bacteria cells will be present in the dish after 3 hours?
3.how many bacteria cells will be present after 12 hours?
The equation is, [tex]\rm y = 30(1+0.50)^x[/tex] 101.25 bacteria cells after 3 hours, and 3892 bacteria cells after 12 hours will be present,
It is given that the sample of bacteria cells in a petri dish increases by 50% every hour, a scientist starts with a sample of 30 bacteria cells.
It is required to find the equation that can be used to determine the number of cells after x hours.
What is Exponential Growth?It is defined as increasing an amount by a definite percentage over the span of a time, the original amount increases exponentially.
We know the Exponential Growth equation written as:
[tex]\rm y= a(1+r)^t[/tex]
Where y = total amount,
a = starting amount
r = the growth rate/exponential decay rate as a decimal
t = number of growth periods.
We have a = 30
r = 50% = 0.50
t = x
Putting these values in the Exponential Growth equation, we get:
[tex]\rm y = 30(1+0.50)^x[/tex] this is the equation for Exponential Growth.
If x = 3 hours, then:
[tex]\rm y = 30(1+0.50)^3 \Rightarrow 30(1.50)^3\Rightarrow 30(3.375)\Rightarrow 101.25\\[/tex]
If x = 12 hours, then:
[tex]\rm y = 30(1+0.50)^1^2 \Rightarrow 30(1.50)^1^2\Rightarrow 30(129.746)\Rightarrow 3892.39\approx 3892[/tex]
Thus, the equation that can be used to determine the number of cells after x hours is, [tex]\rm y = 30(1+0.50)^x[/tex], that 101.25 bacteria cells will be present in the dish after 3 hours, and 3892 bacteria cells will be present after 12 hours.
