if a = and b = -1 what is the value of ab -b^2
Answer:
-2
Step-by-step explanation:
To solve you need to replace the variables with their numbers.
3(-1) - (-1^2)
-1 x -1 = -1
3 x (-1) = -3
-3 - (-1) =
-2
Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.

Three friends are selling items at a bake sale. May makes $23.25 selling bread. Inez sells gift baskets and makes 100 times as much as May. Carolyn sells pies and makes one tenth of the money Inez makes. How much money does each friend make?
May:
Inez:
Carolyn:
Answer:
May = $23.25 Inez = $2325 Carolyn = $232.50
Step-by-step:
May makes that much because it says it in the problem. Inez makes that much because 23.25 times 100 equals 2325. Finally one tenth of 2325 is 232.5
Answer:
may makes 23.25
inez make 2, 325
Carolyn make 232.5

Step-by-step explanation:
he graph below represents the price of sending video messages using the services of a phone company. What is the constant of proportionality? A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The values on the y axis are 0, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240. Points are shown on ordered pairs 0, 0 and 2, 48 and 4, 96 and 6, 144 and 8, 192. These points are connected by a line. The label on the x axis is Video Messages Sent. The label on the y axis is Price in cents. 12 24 46 48
Answer:
24.
Step-by-step explanation:
Basically constant of proportionality is a ratio.
We take two points, we'll take the order pair (2,48)
It will always be y/x so y is 48 and x is 2
48/2 - now we simplify
answer: 24
hope this helps! :))
Help i need answers asap!! there's only a lot of pictures because i waned you to see what i' doing PART !!!!! GO TO MY ACCOUNT AND LOOK AT MY QUESTIONS FOR THE LAST QUESTION
Answer:
The store for b should be $11
Step-by-step explanation:
I would find A for you too but there is no graph! But for example the slope formula is (y2-y1)/(x2-x1)! You would take any big y number and use it as your y2 go up one use it as your y1 subtract it that’s your numerator. Next take your big x2 across from your y2 and then use the one across from y1 and subtract those that’s your denominator!
HELP ASAP! im really stuck because im dumb and if anyone can help that would be appreciated!
Alicia is solving the equation 2.3 x minus 1.6 = 8.8 minus 2.9 x. Which equations represent possible ways to begin solving for x? Check all that apply.
2.3 x minus 10.4 = negative 2.9 x
5.2 x minus 1.6 = 8.8
Negative 6.5 x minus 1.6 = negative 2.9 x
2.3 x + 1.3 = 8.8
2.3 x = 10.4 minus 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+ 1.6 +1.6
2.3 x = 10.4 - 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
-8.8 - 8.8
2.3 x - 10.4 = 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+2.9 x + 2.9 x
5.2 x -1.6 = 8.8
hope this helped :3

A paper popcorn cone measures 4 inches in diameter and is 9 inches high. What is the volume of popcorn that can be contained within this cone? Use 3.14 for pi. Round your answer to the nearest hundredth.
answer choices
41.90 cubic inches
37.68 cubic inches
39.45 cubic inches
40.23 cubic inches
Answer:
The formula for finding volume of a cone is (in this case),
V=(3.14)(r^2)(h/3)
With this formula in mind, you would simply substitute in.
V=(3.14)(2^2)(9/3)
You could work that out for yourself on your own, but to save you the time, it is 37.68 in. cubed.
