Answer: Quadrant III

Explanation:

Let's pick example values for m and b

I'll go for m = -2 and b = 5. Anything works as long as m is negative and b is positive.

We go from y = mx+b to y = -2x+5

Plot this graph as shown below. The line passes through quadrants I, II, and IV. Only quadrant III is not touched at all.

At a gig 0.4 of the audience were female. If there were 100 more male audience members than female, how many were there in the a

pickupchik [31]

Number of females = f
Total number of people in audience = n

0.4n = f
f + (f+ 100) = n
2f + 100 = n

Find n:
f = 0.4n --> Replace f with 0.4n in the equation 2f +100 = n

2(0.4n) + 100 = n --> Multiply out the brackets
0.8n + 100 = n --> Subtract 0.8n from both sides
100 = 0.2n --> To get n, multiply both sides by 5
n = 500

There were 500 people in the audience.

Benny gets a job at a law firm with a salary of 70,000$ per year. After the first year, his salary increases to 73,000$. Over th

Morgarella [4.7K]

Hey there!

Part A- The y-intercept would represent Benny's starting salary: b = 70,000.

The slope would represent Benny's annual raise: m = 3,000.

Part B- The y-intercept is b = 70,000.

The slope is m = 3,000.

The equation representing Benny's annual salary at any given year is y = mx + b, or y = 3,000x + 70,000, where x is the number of years since Benny started the job.

I beg of you to please some-one help..I can't figure this out and it's driving me nuts- I will give Brainlist!

Answer:

A = 70

Step-by-step explanation:

CB is equal to EZ and E equals 35, and E and C are the same, therefore, both E equals 35. Since there's 180 degrees in a triangle, and ABY equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that B equals 75. You have to add E and B (35 + 75), since that's in the same triangle as A. When you do that, you get 110. Subtract 180 - 110 to get A, which is 70.
