Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptA hot air balloon is descending at a rate of 287 feet per minute.
Thus, the rate of change m = -287
The negative sign indicates that a hot air balloon is descending.
Let y be elevation.
Let x be the time (in minutes)
As there is no mentioning of the initial height.
Thus, the y-intercept b = 0
now substituting m = -287 and b = 0
y = mx + b
y = -287x + 0
y = -287x
In order to determine the total change in elevation of the balloon in 4 minutes, we need to substitute x = 4 in the equation y = -287x.
Thus, the total change in elevation of the balloon in 4 minutes will be:
y = -287x
y = -287(4)
y = -1148 feet
The negative sign indicates that that the elevation is decreasing.
Question 3(Multiple Choice Worth 1 points)
(05.04 MC)
The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the outlier is included, then the mean is 84. Which statement is always true about the new data when the outlier is removed?
The mean would decrease.
The mean would increase.
The median would decrease.
The median would increase.
Answer:
The mean would increase
Step-by-step explanation:
The mean would increase
78 is lower than the mean so if you take out a value that's lower than the mean it would obviously increase

An athletics club has junior
(i.e. boy or girl) members and adult members.
The ratio of girls to boys to adults is 3:4:9
and there are 16 more adult members than
junior members. In total, how many members
does the club have
Answer:
The total number of members are 128 members
Step-by-step explanation:
From the question, mixing the ratio of children to adult, we have ;
7:9
There are 16 more adult members
So if there are x children, then there are 16 + x adults
Thus, the total number of members will be;
16 + x + x = 2x + 16
Now, we have that;
7/16 * (2x + 16) = x
7(2x + 16) = 16x
14x + 112 = 16x
16x-14x = 112
2x = 112
x = 112/2
x = 56
The total number of members is thus;
2(56) + 16 = 128
The graph of p = 400 and the graph of p = 50s - 200 intersect at the point (12,400). If the equation p = 50s - 200 represents the profit, p, based on s sales, what does the intersection best represent? Show work.
Answer:
This shows that the profit for 12 sales is 400
Step-by-step explanation:
If both graphs intersects then;
p = p
400 = 50s - 200
50s = 400+200
50s = 600
s = 600/50
s = 12
Substitute s =12 into p = 50s-200
p = 50(12) - 200
p = 600-200
p = 400
Hence the intersection (s, p) is (12, 400)
This shows that the profit for 12 sales is 400

Which statement is true about the y-intercept of a quadratic function?
O A. A quadratic function can only have one y-intercept.
OB. A quadratic function can have up to two y-intercepts.
OC. The y-intercept is also called a zero of the function.
OD. The y-intercept is located at the point where the value of yis 0.
Answer: Every quadratic has a (single) y-intercept. The reason for this is that the y-intercept is the function value at x = 0, and we can always substitute x = 0 into the quadratic. Thus, the y-intercept of the quadratic function y = ax2 + bx + c is c.
Step-by-step explanation:
It’s algebra it says find each function value here is a picture of the work sheet
1.
8 > 1 so: a(x) = -4x + 7
a(8) = - 4(8) + 7 = - 32 + 7 = - 25
2.
-6 ≤ 1 ≤ 1 so: a(x) = 2x - x²
a(1) = 2(1) - (1)² = 2 - 1 = 1
3.
-7 ≤ -6 so: a(x) = |x - 8|
a(-7) = |-7 - 8| = |-15| = 15
4.
-6 ≤ -3 ≤ 1 so: a(x) = 2x - x²
a(-3) = 2(-3) - (-3)² = -6 - 9 = - 15
5.
-6 ≤ -¹/₂ ≤ 1 so: a(x) = 2x - x²
a(-¹/₂) = 2(-¹/₂) - (-¹/₂)² = - 1 - ¹/₄ = - 1¹/₄
6.
⁹/₄ > 1 so: a(x) = -4x + 7
a(⁹/₄) = - 4(⁹/₄) + 7 = - 9 + 7 = - 2

Suppose y varies directly with x when x is 4, y is 32. What is y when x is -2
Step-by-step explanation:
Since y varies directly with x,
y = kx, where k is a real constant.
When x = 4, y = 32.
=> (32) = (4)k, k = 8.
Therefore when x = -2,
y = kx = (8)(-2) = -16.
