Answer:
y=8x+7
Step-by-step explanation:
Use the form y=mx+b
M= the slope
B= the y-intercept
y=8x+?
Since the y coordinate of (0,7) is 7
b=7
So y=8x+7
A box contains 4 red marbles, 3 green marbles and 2 blue marbles. One marble is removed from the box and it is NOT replaced. Another marble is drawn from the box. What is the probability that the first marble is blue and the second marble is green?
The required probability is [tex]\dfrac{1}{12}[/tex].
Important information:
Red marbles = 4Green marbles = 3Blue marbles = 2Probability:Total number of marbles is:
[tex]4+3+2=9[/tex]
The probability of getting a blue marble is [tex]\frac{2}{9}[/tex].
After removing a marble, the number of remaining marbles is 8. So, the probability of getting a green marble is [tex]\frac{3}{8}[/tex].
Now, the probability that the first marble is blue and the second marble is green is:
[tex]P=\dfrac{2}{9}\times \dfrac{3}{8}[/tex]
[tex]P=\dfrac{1}{12}[/tex]
Therefore, the required probability is [tex]\dfrac{1}{12}[/tex].

Which type of angle is Angle A B C?
Angle A B C is a straight angle.
Angle A B C is a vertical angle.
Angle A B C is a right angle.
Angle A B C is a complementary angle.
Answer:
Angle ABC is a right angle. So option C is correct.
What is the right triangle?
A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
The angle of a right angle is always 90 degrees.
IT is given that the Angle A B C is intersected by a line to form angles 25 degrees and 65 degrees.
If we add up 25 and 65 degrees, we get 90 degrees.
25 + 65 = 90
Thus, Angle ABC is a right angle because right angles are 90 degrees.
Therefore Angle ABC is a right angle. So option C is correct.

Abigail tosses a coin off a bridge into the stream below. The distance, in feet, the coin above the water is modeled by the equation y=−16x2+96x+112 When does the coin hit the water?
Answer:
7 seconds
Step-by-step explanation:
Distance of the coin above the water is modeled by the equation
[tex]y=-16x^2+96x+112[/tex]
where [tex]x[/tex] is time taken to cover the distance
Now equating with zero.
[tex]0=-16x^2+96x+112\\\Rightarrow 16x^2-96x-112=0\\\Rightarrow x=\dfrac{-\left(-96\right)\pm \sqrt{\left(-96\right)^2-4\times \:16\left(-112\right)}}{2\times \:16}\\\Rightarrow x=7, -1[/tex]
So, time taken by the coin to hit the water is 7 seconds.

The graph shows the function f(x) = (2.5)x was horizontally translated left by a value of h to get the function g(x) = (2.5)x–h.
On a coordinate plane, 2 exponential functions are shown. f (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. It goes through (negative 1, 0.5) and crosses the y-axis at (0, 1). g (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. It goes through (negative 2, 1) and crosses the y-axis at (0, 6).
What is the value of h?

Answer:
-2
Step-by-step explanation:
Edge2021
Using translation concepts, it is found that the value of h is 5. so option D is correct.
What is a translation?A translation can be represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
When the expression of function is such that it involves the input to be present as exponent of some constant, then such function is called exponential function.
In this problem, function f(x) is defined by:
[tex]f(x) = (2.5)^x[/tex]
Function g(x) is defined by
[tex]g(x) = (2.5)^x-h[/tex]
OR
[tex]g(x) = (2.5)^x + g[/tex]
Since f(x) the y-axis at (0,1), while g(x) crosses it at (0,6), which means that g(x) is f(x) added to 5, hence h = 5.
Using translation concepts, it is found that the value of h is 5. so option D is correct.

Given point A (-9, -9) and B (5, -2) find the coordinates of point P on the directed line segment AB in the ratio 3:4.
Answer:
We have point P(-3,-6).
Step-by-step explanation:
We want to find a point P(x,y).
Since it is on the directed line segment AB in the ratio 3:4, it means that:
[tex]P - A = \frac{3}{3+4}(B - A)[/tex]
So
[tex]P - A = \frac{3}{7}(B-A)[/tex]
We apply this to both the x-coordinate and y-coordinate of P.
x-coordinate:
x-coordinate of A: -9
x-coordinate of B: 5
x-coordinate of P: x
So
[tex]P - A = \frac{3}{7}(B-A)[/tex]
[tex]x - (-9) = \frac{3}{7}(5-(-9))[/tex]
[tex]x + 9 = \frac{3}{7} \times 14[/tex]
[tex]x + 9 = 6[/tex]
[tex]x = -3[/tex]
y-coordinate:
y-coordinate of A: -9
y-coordinate of B: -2
y-coordinate of P: y
So
[tex]P - A = \frac{3}{7}(B-A)[/tex]
[tex]y - (-9) = \frac{3}{7}(-2-(-9))[/tex]
[tex]y + 9 = \frac{3}{7} \times 7[/tex]
[tex]y + 9 = 3[/tex]
[tex]y = -6[/tex]
We have point P(-3,-6).

25 feet in 4 seconds; 80 feet in x seconds write a proportion for each phrase and solve it
Answer:
12.8 seconds
Step-by-step explanation:
Create a proportion where x is the number of seconds for 80 feet
[tex]\frac{25}{4}[/tex] = [tex]\frac{80}{x}[/tex]
Cross multiply and solve for x
25x = 320
x = 12.8
So, the answer is 12.8 seconds
If the average crowdfunding campaign investment is about $90 and the average number of investors is about 80, what is the best approximation of the average amount raised in a crowdfunding campaign?
Answer:
A) $7200
Step-by-step explanation:
The required average amount raised in a crowdfunding campaign is $7200.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
The average crowdfunding campaign investment is about $90 and the average number of investors is about 80 which is given in the question.
To determine the average amount raised in a crowdfunding campaign.
The required average amount raised in a crowdfunding campaign is the product of the average crowdfunding campaign investment and the number of investors.
As per the given information,
The average amount raised = $90 × 80 = $7200
Therefore, the required average amount raised in a crowdfunding campaign is $7200.
