Answer:
1
Step-by-step explanation:
you should remove 8 out of 10 then 2 will remain
then add negative 5 to both sides then we will left with -3x = -3
divide -3 on both sides we find x = 1
Answer:
x=1
Step-by-step explanation:
-3x + 5= -8 + 10
Combine like terms
-3x+5 = 2
Subtract 5 from each side
-3x+5-5 = 2-5
-3x = -3
Divide by -3
-3x/-3 = -3/-3
x =1

Write a function g whose graph represents a translation 3 units down followed by a vertical shrink by a factor of 1/3
of the graph of f(x) = x
If a function 'f' is translated by 'k' units down, image function 'g' will be,
g(x) = h(x) - 3If the function 'g' gets shrink by a factor 'm', the new function 'k' will be,

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]

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.

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

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

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

We need to find the yards of ribbon that Elsa bought with her debit card.
The amount of ribbon that Elsa bought was 31 yards.
Initial amount which is present on the card is [tex]\$15[/tex]
Amount left after spending is [tex]\$12.83[/tex]
Amount spent on ribbon is [tex]15-12.3=\$2.17[/tex]

Cost of one yard of ribbon is [tex]7\ \text{cents}[/tex]
[tex]1\ \text{yd}=7\ \text{cents}\\\Rightarrow 1\ \text{cent}=\dfrac{1}{7}\ \text{yd}\\\Rightarrow 217\ \text{cents}=\dfrac{217}{7}=31\ \text{yd}[/tex]

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.
