Answer:
Step-by-step explanation:
Suppose we decide to solve for y first. y will then be in terms of x AND a real and an imaginary term:
48-5i=-4x+10yi
The goal here is to solve for y. Adding 4x to both sides yields
48 - 5i + 4x = 10yi
and then we divide both sides by 10i to isolate the variable y:
48 - 5i + 4x
----------------- = y This result is "y in terms of the constant 48, the
10i imaginary terms 5i and 10i, and the expression 4x.
We solve the original equation for x in a similar manner:
48-5i=-4x+10yi becomes 48 - 5i - 10yi = -4x, so that:
-(48 - 5i - 10yi)
x = ------------------------
4
Next time, please specify which variable (x or y) you're solving for. Thank you.

A right triangle needs to have all the sides of the same length. Since this obviously does not, it is not a right triangle. Infact, this is a scalene triangle because all of its sides are unequal.

18. You have no more than $60 to spend. You want a drink that costs $1.50 including tax, and you want to buy a
pair of pants, which will have 4% sales tax.
a.) What is the inequality that represents the amount of money you have to spend?
b.) Given that you can spend no more than $60, what is the most a pair of pants could cost?
Answer:
a. pants + tax + drink ≤ 60 b. $56.16
Step-by-step explanation:
60-1.5 = 58.5 = money left for pants+tax
58.5/100 = 0.585 = 1%
0.585x 4= $2.34 = highest possible tax
58.5 - 2.34 = $56.16 most
pants + tax + drink ≤ 60

2. Mary answered 6 questions correctly on her Biology test.
She answered 20% of the questions correctly. In total, how
many questions were on the Biology test?
Answer:
60
Step-by-step explanation:
if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20
Answer:
The Answer is 30 questions in total.
Step-by-step explanation:
1. The first thing you would want to do is to break down this question.
For every 6 questions, this is 20% of the test done.
2. You now would want to divide 100% (the full amount on the test) by 20%.
100%/20% = 5
3. Now, multiply both to get your answer.
6·5= 30
20%x5= 100%.
Therefore, the total amount of questions on the test is 30 questions.
Just identify if this is rational or not :))

Find the surface area and volume of the basketball. Round your answer to the nearest hundredth.
Answer:
Surface area: 277.59 in^2
Volume: 434.89 in^3
Step-by-step explanation:
Radius = C/(2*pi)
29.5/3.14 = 9.39
Radius = 9.39/2 = 4.7 in
A = 4 pi r^2
A = (4) (3.14) (4.7)^2
A = 277.59 in^2
Volume = (4/3) (pi)(r)^3
(4/3)(3.14)(4.7)^3
= 434.89 in^3
Answer:
Surface area: [tex]277.59[/tex] in^[tex]2[/tex]
Volume: [tex]434.89[/tex] in^[tex]3[/tex]
Explanation:
Radius = C/([tex]2[/tex]*[tex]Pi[/tex])
[tex]29.5/3.14[/tex] = [tex]9.39[/tex]
Radius = [tex]9.39/2[/tex] = [tex]4.7[/tex] in
A = [tex]4[/tex] [tex]Pi[/tex] r^[tex]2[/tex]
A = ([tex]4[/tex]) ([tex]3.14[/tex]) ([tex]4.7[/tex])^[tex]2[/tex]

how do i calculate slope?
Answer:
In order to calculate the slope, you'll need 2 ordered pairs (x, y).
The formula for calculating the slope is:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
where m = slope
(x1, y1) = first ordered pair
(x2, y2) = second ordered pair
Regardless of which values for the (x1, y1) and (x2, y2) you choose, you would still end up with the same slope (as long as it's done correctly).
As an example, let's say you have the following set of points:
(2, 4) (8, 1)
Let (x1, y1) = (2, 4)
(x2, y2) = (8, 1)
Plug these values into the slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]m = \frac{1 - 4}{8 - 2} = \frac{-3}{6} = -\frac{1}{2}[/tex]
Therefore, the slope of the line is - 1/2.
To prove that you'll end up with the same value for the slope:
This time, let (x1, y1) = (8, 1)
(x2, y2) = (2, 4)
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]m = \frac{4 - 1}{2 - 8} = \frac{3}{-6} = - \frac{1}{2}[/tex]
Therefore, the value of the slope is still -1/2.

d
y=x+5, (8, 1)
Answer:
y = x - 7
Step-by-step explanation:
Parallel lines have the same gradient in this case 1 is the gradient.
Using the point (8,1) we can form our own equation.
1 will be y, 1 will be m, 8 will be x
All we have to do is find C in order to form the equation y=mx+c
1 = 1(8) + c
1 = 8 + c
C = - 7
Therefore;
y = x - 7
