2. is 5 + (4 * i) - (9 - i) = -4+5i

3. is (5 * i) - 3 - (7 + (2 * i)) = -10+3i

4. is (9 * i) + 3 - (4 + (3 * i)) = -1+6i

how do you convert x + 5y =-5 into slope intercept form?

Answers

Answer:Convert it to the slope intercept form by solving for y . Add x to both sides. Divide both sides by 5 . y=15x−1 is the slope intercept form of a linear equation, y=mx+b , where m is the slope, 15 and b is the y-intercept, −1

How do I do this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

x = 5

Step-by-step explanation:

39° + 90° + (7x + 16)° = 180°

39 + 90 = 129

180 - 129 = 51

7x + 16 = 51

7x + 16 - 16 = 51 - 16

7x = 35

7x/7 = 35/7

x = 5

Alg. 1 question, I will mark brainliest for the best/first answer!
One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54 inches. What are the dimensions of the rectangle?

Which of the following equations could be used to solve the problem?
A. 2 x + 2( x - 3) = 54
B. 2 x - 3 = 54
C. 2 x + 2 x - 3 = 54

Answers

Answer:

Step-by-step explanation:

Let the two sides of the rectangle be x and y.

Then the perimeter will be:

[tex]2x+2y=P[/tex]

Since the perimeter is 54:

[tex]2x+2y=54[/tex]

We know that one side of the rectangle is 3 inches shorter than the other.

Let y be the shorter side. It is 3 less than x.

Therefore:

[tex]y=x-3[/tex]

Then by substitution, we acquire:

[tex]2x+2(x-3)=54[/tex]

The answer is A.

Jackson and his sister ran a hose from a bucket into their swimming pool. The hose sprays 1/3 of a gallon from the bucket every second. The bucket started with 32 gallons of water. How long will it take to empty the bucket?

Answers

Answer:

96 seconds

Step-by-step explanation:

In order to find how long it will take to empty the bucket, you must multiply the number of gallons by the reciprocal of the fraction.

1. Reciprocal of [tex]\frac{1}{3}[/tex] is [tex]\frac{3}{1}[/tex] which is 3

2. multiply 32 by 3 to get your answer, 96.

what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?

Answers

Answer: The other point is (17, -6).

Step-by-step explanation:

Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-

[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]

Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).

Let other point be (a,b), then

[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]

hence, the other point is (17, -6).

Which is the graph of y= 3/4x - 3?

Answers

The answer is Graph A.

The equation is written in slope-intercept form y=mx+b, so the slope m is 3/4, and the y-intercept is -3.

You can immediately eliminate graph B because its y-intercept is 3, not -3.

Then, you can count the rise/run for the other two graphs to see which one has a rise/run of 3/4. That’s graph A (graph C has a rise/run of 3/2, so it’s wrong).
