Step-by-step explanation:
An ice cream truck driver used the equation Y=KX to show how much money he made selling 9 ice cream bars. He determined he'd make $24.93. How much did he make per bar sold?
Answer:
$2.77 per bar sold
Step-by-step explanation:
Hi there!
We're given that selling 9 ice cream bars could make the truck driver $24.93. To find how much he'd make per bar sold, divide $24.93 by 9 ice cream bars:
24.93 ÷ 9 = 2.77
Therefore, the truck driver would make $2.77 per bar sold.
We could also find this answer using the given equation, y=kx.
y=kx
Let y equal the earnings. Let x equal the number of ice cream bars sold. Let k equal how much the driver would make per bar sold.
24.93=k(9)
24.93=9k
x=2.77
I hope this helps!
4x - y/2y +x
------- x=3 y=3
Answer:
B
Step-by-step explanation:
4x - y = 4*3 - 3 = 12 - 3 = 9
2y + x = 2*3 + 3 = 6 + 3 = 9
(4x - y) / (2y + x ) = 9/9 = 1
f(x) = -x + 1; reflection in the y-axis
Can the sum of two irrational numbers ever be a rational number? Can the quotient of two irrational numbers ever be a rational number
Answer:
Yes and yes
Step-by-step explanation:
Example:
√2, 1 + √2 and 1 - √2 are all irrational.
(1 + √2) + (1 - √2) = 2
The irrational numbers cancel out, leaving you with 1 + 1 = 2, which is rational.
For quotients, we'll use √2 again.
√2/√2 = 1
1 is rational
how would i write The difference of three times a number and 4 is -19 in a equation?
Hi! I'm happy to help!
To solve this, we first have to understand the terms and the way they arrange the equation.
First, we have the difference of ____and_____=. (the "is" after 4 refers to equals)
We will write this as:
_______-_______= ,because difference means subtraction.
For our first blank, we have 3 times a number. Because we do not know this number, we will use a variable.(n) 3 times a number is 3 multiplied by a number. We can just write 3n, because it represent multiplication.
3n-______=
Now, we see the part of the equation after the "and". We just see 4, so we can insert that here:
3n-4=
Now, we see what is shown after the "is".
We just have -19, so we can insert that here:
3n-4=-19
Now, let's solve (not sure if I need to):
To solve for n, we have to isolate it on one side of the equation. To do this, let's cancel out the -4 on the left side of the equation by adding 4 to both sides:
3n=-15
From here, we need to get rid of the 3 next to the n by dividing both sides by 3:
n=-5
So, we write it as 3n-4=-19, and n=-5.
I hope this was helpful, keep learning! :D

The midpoint of UV is (5, -11). The coordinates of one endpoint are U(3,5). Find the coordinates of endpoint V.
The coordinates of endpoint V is (7, -27) if one endpoint is U(3,5) and the midpoint of UV is (5, -11)
Midpoint of a line is a point that divides any line into two equal parts.
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as:
[tex]M(X, Y)= (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )[/tex]
Given the following
midpoint of UV = (5, -11)
U = (3, 5)
Get the other coordinate x2 and y2
Based on the formula above:
[tex]X = \frac{x_1+x_2}{2}\\5=\frac{3+x_2}{2}\\10 = 3 + x_2\\x_2 = 10-3\\x_2 = 7[/tex]
Get the other coordinate x2
[tex]Y = \frac{y_1+y_2}{2}\\-11=\frac{5+y_2}{2}\\-22 = 5 + y_2\\y_2 = -22-5\\y_2 = -27[/tex]
This shows that the coordinates of endpoint V is (7, -27)

Find the measure of JL.[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Given, K is the midpoint of JL. So, JK = KL.
KL = 14x - 1JK = 8x + 11JL = ?________
JL = JK + KL (given that K is the midpoint of JL)
JL = (8x + 11) + (14x - 1)
________
[tex] \large \boxed{\mathfrak{Steps} \downarrow}[/tex]
[tex] \sf( 8 x + 11 ) + ( 14 x - 1 )[/tex]
Combine 8x and 14x to get 22x.
[tex] \sf \: 22x+11-1 [/tex]
Subtract 1 from 11 to get 10.
[tex] \boxed{ \boxed{ \bf22x+10 }}[/tex]
________
Also given that, JK = KL.
So, (8x + 11) = (14x - 1)
⇨ (8x + 11) = (14x - 1)
⇨ 8x + 11 = 14x - 1
⇨ 11 + 1 = 14x - 8x
⇨ 12 = 6x
⇨ x = 12 / 6
⇨ [tex] \boxed{ \boxed{ \bf \: x= 2 }}[/tex]
________
Now, value of JL will be,
JL = 22x + 10
Substitute the value of x.
JL = 22(2) + 10
JL = 44 + 10
[tex] \boxed{ \boxed{ \bf\: JL = 50 }}[/tex]
⇨ So, the value of JL will be 50 units.

Which of the following are the coordinates of the vertex of y = −x2 + 2x + 1? (2, 1) (1, –2) (1, 2) (–2, 1)
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:
[tex]\displaystyle y = -x^2 + 2x + 1[/tex]
Recall that the vertex is given by the formulas:
[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In this case, a = -1, b = 2, and c = 1.
Determine the x-coordinate of the vertex:
[tex]\displaystyle x = -\frac{(2)}{2(-1)} = 1[/tex]
To determine the y-coordinate, evaluate the function at x = 1:
[tex]\displaystyle \begin{aligned} y(1)&= -(1)^2 + 2(1) + 1 \\ &= 2\end{aligned}[/tex]
In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.

Elsa got a prepaid debit card with $15 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 7 cents per yard. If after that purchase there was $12.83 left on the card, how many yards of ribbon did Elsa buy?
Answer:
31 yards
Step-by-step explanation:
If she has $12.83 left, that means she spent $2.17 out of the $15
15 - 12.83 = 2.17
One cent is .01 of a dollar
So that would be $0.07 per yard
To find the number of yards, we need to divide the total amount she spent by the price per yard.
2.17 ÷ 0.07 = 31
