Answer:

1. Second Choice

2. Positive

3. Line B

4. Line D

5. Horizontal

Step-by-step explanation:

First Screenshot

The y-intercept is the value of b —

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.

Basically (0,a) is y-intercept.

Thus, our y-intercept is (0,1)

Second Screenshot

The slope is positive. If the slope is negative, it would face opposite.

For zero slope, the graph will become a horizontal line.

An undefined slope is the vertical line graph.

Third Screenshot

Line B has zero slope. As said, the zero slope will turn the graph into a horizontal line.

Fourth Screenshot

Line D has an undefined slope. Read Third Screenshot.

As said, an undefined slope is the vertical line.

Fifth Screenshot

[tex]y = - 3[/tex]

This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)

FYI,

y = a — horizontal

x = a — vertical

Answer:

-1 -9i, where a = -1 and b = -9

Step-by-step explanation:

1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.

4-i-5-8i

Then we collect like terms.

-1 -9i

This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.

This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.

Answers

Answer:

12%

Step-by-step explanation:

600-528=72. (subtract)

72/600= 3/25. (simplify)

3/25 = 12%. ( convert to percent)

(answer accuracy not garunteed)

Answer:

600-528 = 72

72/600 = 0.12

0.12 X 100 = 12 %

It is reduced by 12 %

find the probability that a number chosen at random from the integers between 5 and 16 inclusive is a multiple of 3 or a mutiple of 2

Answers

Answer: Numbers between 5 and 16 are:-

6, 7, 8, 9, 10, 11, 12, 13, 14 , 15 and 16.

Therefore, total number of outcomes =11

Numbers inclusive between 5 and 16 which are divisible by 2 or 3 are-

6 , 8, 9 ,10 ,12, 14 and 15.

Number of favourable outcomes = 7

Therefore, probability of getting a number which is either a multiple of 2 or 3 is:

p(e) = \frac{7}{11}p(e)=

11

7

HENCE, THE REQUIRED PROBABILITY IS = 7 / 11.

Write an equation of the line that passes through (2,-1) and is parallel to the line y=-3x+8

Answers

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 8 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, then

y = - 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - 3x + 5 ← equation of line

The  statements describe America’s workforce during World War II are:

Hundreds of thousands of women signed up for the US military. Women were hired to do jobs traditionally done by men. New laws ended discrimination in the government and defense industries. More African Americans and other minority workers were able to find jobs.

What happened to the American labour force during World War II?

Labor shortages were caused by military and economic development. To close the gender gap, the government and industry encouraged women to enter the labour force. While the majority of working women continued to work in more traditional jobs such as waitressing and teaching, millions took better-paying jobs in military manufacturers.

By the end of the war, over six million women had entered the labour sector, and by 1945, they accounted for about 37 percent of the workforce, up from only 27 percent in 1940.

Their contributions to the war effort were critical. Women accounted up 65 percent of all employees in the aerospace industry alone.

Answer:

y = 2/3x + 1.5

Step-by-step explanation:

The Formula for that is

y = mx + b

m = slope

b =  y -intercept

so to find the slope I would do y/x or rise over run

So your slope is 2/3 ( it goes up 2 and right 3 times)

Since the line is going up and not down, it is a positive slope

y = 2/3x + b

we need to find where the line crosses the  vertical / y-axis and it's at the point.... (0,1.5)

y = 2/3x + 1.5

Problem 2: y^8/9x^2

Step-by-step explanation:

In the first problem, you first need to multiply the -2 exponent to everything in the parenthesis. This is equal to 1/64x^4*-2, simplified to be 1/64x^-8. Finally you simplify the x to 1/64x^8.

For the second problem, you do the same in the first one, getting x^-2/9y^4*-2. This can be simplified to be 3x^-2/y^-8. Finally you make sure there is no negative exponents, so you do y^8/9x^2.

Ok so you wanna start at the y intercept, which is -4 and make a dot there. The slope is 2/3 which is y over x. So from -4, go up 2 and over to the right 3. You could also go down 2 and to the left 3 because two negatives make a positive.
