<u>Answer:</u>
Below!
<u>Step-by-step explanation:</u>
Let's use the formula to identify the correct slope and y intercept.
We know that:
- Formula = y = mx + b
Option 1: (y = 3x)
Let's compare y = 3x with the formula.
- (y = 3x) = (y = mx + b)
<u>We can clearly see that the slope(m) is 3 and the y-intercept(b) is 0.</u>
Final answer: m = 3, b = 0
__________________________________________________________
Option 2: (y = 1.5x - 7)
Let's compare y = 1.5x - 7 with the formula.
- (y = 1.5x - 7) = (y = mx + b)
<u>We can clearly see that the slope(m) is 1.5 and the y-intercept(b) is -7.</u>
Final answer: m = 1.5, b = -7
<h3>__________________________________________________</h3>Option 3: (y = 7)
Let's compare y = 7 with the formula.
- y = 7 = (y = mx + b)
<u>We can clearly see that the slope(m) is 0 and the y-intercept(b) is 7.</u>
Final answer: m = 0, b = 7
<h3>__________________________________________________</h3>Option 4: (y = -1.5x - 4)
Let's compare y = -1.5x - 4 with the formula.
- (y = -1.5x - 4) = (y = mx + b)
<u>We can clearly see that the slope(m) is -1.5 and the y-intercept(b) is -4.</u>
Final answer: m = -1.5, b = -4
<h3>__________________________________________________</h3>Option 5: (y = -3x + 4)
Let's compare y = -3x + 4 with the formula.
- (y = -3x + 4) = (y = mx + b)
<u>We can clearly see that the slope(m) is -3 and the y-intercept(b) is 4.</u>
Final answer: m = -3, b = 4

Answer:
x = 30 and x = 3 both solve the equation correctly. See work below.
Step-by-step explanation:
The very first step is to realize that p(x) is in hundreds of dollars and that the given number is not. 60000 is not in hundreds of dollars. It is in dollars. 60000 dollars = 60000/100 = 600 hundreds of dollars.
Make the polynomial = 600
-x^3+3x^2+900x-2100 = 600 Subtract 600 from both sides
-x^3+3x^2+900x-2100 - 600 = 0 Combine
-x^3+3x^2+900x- 2700 = 0 Group the first and second term and the Thrid and fourth terms.
(-x^2 + 3x^2) + (900x - 2700) = 0 Bring out the common factors from both groups.
-x^2(x - 3) + 900(x - 3) = 0 Factor out x - 3 on both sides of the plus sign
(- x^2 + 900)(x - 3) = 0 Reverse -x^2 + 900 to 900 - x^2
(900 - x^2)(x - 3) = 0 factor (900 - x^2) using the difference of squares
(30 - x)(30 + x) (x - 3) = 0
The two answers that work are
30 - x = 0 Solve
- x = - 30 Divide by - 1
-x/-1 = -30/-1 Combine
x = 30
============
x - 3 = 0
x = 3
===========
There are two values that will work to give p(x) = 600. There is no way to account for why both values work.
The graph below confirms both answers.
Answer:
1) ven diagram #1
2)160
3) 420
4)16
Step-by-step explanation:
1) lets make a ratio table:
(look at image below, sorry for the horrible writing)
the original ratios are 18 and 17, and 18+17=35 35 is the number of students who play either or both sports. 30 is the number who play either sport:
so 35-30=5
5 students play both sports:
18-5=13(baseball)
17-5=12(basketball)
2) add up all the students who do band or sports and subtract from the total number of students
so
89/464+215/464= 304/464 students play in band or orchestra or both, to find the number of students who dont:
464-304=160
3) 630/1000+420/1000=1050/1000
1050/1000-210/1000=840/1000
840/1000-420/100=420/1000
420 ppl use brand p
4) 15+9=24
40-24=16
16 ppl
hope this helps!
