I’ve been using the elimination method but I keep getting the wrong answer. The answer I’m getting is (-3/2,-7/2). I’m just trying to not get fractions as an answer. Thanks for helping out if you can! (I still need to use elimination method without getting a fraction in the ordered pair)

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
Answers
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

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!

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
Answers
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

Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answers
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.
