Answer:
16 pair of shoes
Step-by-step explanation:
If Gayle donated x pairs, it means he is left with 30 - x pair of shoes.
Bonnie donated half as many as Gayle as donated.
We know Gayle donated x pairs, so Bonnie must have donated x/2.
Bonnie is left with 22 - (x/2) pairs after donation.
The question says, after donation they have the same number of pair of shoes.
It means, 30 - x = 22-(x/2),
If you will manipulate this equation and make x the subject,
you will get x=16.
I hope it helps.
Gayle donated 16 shoes
Number of shoes Gayle has after the equation can be represented with this equation : 30 - x
Where x = number of shoes she donated
Number of shoes Bonnie donated = 0.5x
Number of shoes Bonnie has after the equation can be represented with this equation : 22 - 0.5x
If Bonnie and Gayle ended with the same amount of shoes after the donation, this can be represented as:
30 - x = 22 - 0.5x
Combine similar terms
30 - 22 = x - 0.5x
8 = 0.5x
Divide both sides of the equation by 0.5
x = 16

The equation of the linear function in slope-intercept form is [tex]f(x) = \frac{1}{2}x - 5[/tex]
The equation of a linear function can be written in the slope intercept form as:
f(x) = mx + b,
where,
m represents the slope of the linear function
b represents the point on the y-axis where the line intercepts the y-axis. (at this point, x = 0)
we need to find the value of m and b to be able to write the equation of the linear function.
Find slope (m):
From the image attached, the red line represents the rise (3 units) while the blue line represents the run (6 units).
Slope (m) = rise/run
Substitute:
Slope (m) = 3/6
m = 1/2
Find the y-intercept (b):
From the graph, the line cuts the y-axis at y = -5.
Therefore,
b = -5
Next is to substitute m = 1/2 and b = -5 into f(x) = mx + b. Thus:
[tex]f(x) = \frac{1}{2}x - 5[/tex]
The equation of the linear function is: [tex]f(x) = \frac{1}{2}x - 5[/tex]

Find the point on y axis which is equidistant from the point (5,-2) and (-3,2)
Answer:
(0, -2)
Step-by-step explanation:
a point on the y-axis. that means x=0.
so, the distance of (5, -2) to (0, y) is the same as the distance from (-3, 2) to (0, y).
the distance between (5, -2) and (0, y) is based on Pythagoras (the differences in x and y directions are the sides of a right-angled triangle, and the distance is its Hypotenuse, its baseline) :
distance² = (5-0)² + (-2 - y)² = 25 + 4 + 4y + y² = 29+4y+y²
but it is also
distance² = (-3-0)² + (2 - y)² = 9 + 4 - 4y + y² = 13 - 4y + y²
so, we get
29 + 4y + y² = 13 - 4y + y²
29 + 4y = 13 - 4y
16 = -8y
y = -16/8 = -2
their, the point on the y-axis being equidistant to both points is (0, -2)

Write the slope intercept form of the equation of each line
Answer:
Equation is y = 5x - 6
Step-by-step explanation:
[tex]y = mx + c[/tex]
m is slope, and c is y-intercept:
[tex]slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
(x1, y1) = (1, -1)
(x2, y2) = (0, -4)
[tex]m = \frac{ - 4 - 1}{0 - 1} \\ \\ m = 5[/tex]
for y-intercept, consider (1, -1):
[tex]y = mx + c \\ - 1 = (5 \times 1) + c \\ - 1 = 5 + c \\ c = - 6[/tex]
substitute in general equation:

ZC and ZD are vertical angles with MZC = –2x + 90 and MZD = x – 30.
What is mZD
Enter your answer in the box.
Answer:
10
Step-by-step explanation:
Vertical angles are equal to each other
-2x + 90 = x - 30
90 + 30 = x + 2x add like terms
120 = 3x divide both sides by 3
40 = x
angle <ZD is x - 30 so the answer is 10

Hello,

Step-by-step explanation:

i^3-i^3=0
Answer D
Answer: D) 0
======================================================
Explanation:
Take note of this pattern
i^0 = 1i^1 = ii^2 = -1i^3 = -ii^4 = 1After this point, we repeat the cycle. The cycle is 4 units long. This means we can divide the exponent over 4 and look at the remainder
99/4 = 24 remainder 3
So i^99 = i^3
which means i^99 - i^3 = i^3 - i^3 = 0
