What is the measure in each angle? A? B? C?
Answers
Answer:
∠A = 48°, ∠B = 48°, and ∠C = 84°
Step-by-step explanation:
AB = CB Given
m ∠A = m ∠C If opposite sides are =, then those opposite angles are =
6(x - 3) = 4(x + 1)
6x - 18 = 4x + 4
2x - 18 = 4
2x = 22
x = 11
m ∠A = 6(11 - 3) = 6(8) = 48°
m ∠C = 4(11+ 1) = 4(12) = 48°
The sum of the angles in a triangle = 180°
48° + 48° m ∠B = 180°
96°+ m ∠B = 180°
84° = m ∠B

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|.
Answers
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.

This graph represents −3x+y=−4. Which ordered pair is in the solution set of −3x+y≥−4?
Answers
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

A rectangular field has the area equal to that of a square field of side 60m.if the breadth of the rectangular field is 32m, find it's length
Answers
Given -
Area of rectangular field = Area of square field side of square = 60mbreadth of the rectangular field = 32mTo find -
length of the rectangular fieldSolution -
Area of square = side × side = (60 × 60)m² =
Area of square =3600m²
Hence,
Area of rectangular field = Area of square field = 3600m²
Area of rectangular field = l × b = 3600m²
=> l × 32m = 3600m²
=> l = [tex]\sf{\frac{3600}{32}\:m}[/tex]
=> l = 112.5m
so, the length = 112.5m
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?
Answers
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.

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?
Answers
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]

Answers
(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).
