name 3 lines that are not perpendicular to y=2x-3
2.3r-y+6=21
Find r when y=7
Find y when r=4.23
Step-by-step explanation:
2.3r - 7 + 6 = 21
2.3r - 1 = 21
2.3r = 22
r = 22/2.3
r = 9.6
2.3(4.23) - y + 6 = 21
9.73 - y + 6 = 21
15.73 - y = 21
-y = 5.27
y = -5.27

Step-by-step explanation:
4.4 = –13.6 + 3t how would i solve this step by step
Answer:
t = 6
Step-by-step explanation:
First, add 13.6 (inverse operation)
18 = 3t (divide by 3)
6 = t
sub in to check
Answer:
t=6
Step-by-step explanation:
4.4=-13.6+3t [add -13.6 to both sides]
18=3t [divide 3 from 18]
t=6
5(r + 3) = 3r + 35.
What is the answer and please show how you got it
Answer:
r =10
Step-by-step explanation:
5(r + 3) = 3r + 35.
Distribute
5r+15 = 3r+35
Subtract 3r from each side
5r+15-3r = 3r+35-3r
Combine like terms
2r +15 = 35
Subtract 15 from each side
2r+15-15 =35-15
2r = 20
Divide by 2
2r/2 =20/2
r =10
what are the two characteristics we look for when trying to solve a quadratic equation?
A. A positive coefficient for x^2 & the equation set equal to 0
B. Factor and cancel
C. Distribute like terms
D. There is no such thing as a quadratic equation
Answer:
Answer A makes the most sense by far.
Step-by-step explanation:
Answer A makes the most sense by far. However, strictly speaking, the coefficient of x^2 does not have to be positive if we're using the quadratic formula. Using some other approach, such as factoring, obtaining a positive coefficient for x^2 is helpful.
Which expressions have a quotient of 4/5
a. 5/2 ÷ 1/2
b.6/9 ÷ 5/6

PLEASE I'M NOT SURE WHAT TO DO: Write the following equation in point-slope form: 16. The cost to rent a video game at a rental store can be modeled by a linear function. Renting a game for 1 night costs $1.50 and renting a game for 2 nights cost $2.7%. Write a linear equation that models the total cost of renting a game, y, as a function of the number of nights rented, x. Hint: find your ordered pairs then slope, point slope form is y-yı = m(x - x1)

Based on the regression output, which of the following is the predicted time, in minutes, that it took to gather the items if the order has 22 items?
Answer:
The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
Step-by-step explanation:
Regression Output :
Predictor Coefficient
Constant 3.0979
Square root of items 2.7633
R.sq.- 96.7%
So, with this data the regression equation is,
[tex]\hat{y}=3.0979+2.7633x[/tex]
Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items
Substitute x =22 in equation
[tex]\hat{y}=3.0979+2.7633(22)[/tex]
[tex]\hat{y}=63.8905[/tex]
Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

The cost of Marianne's old bracelet is two-thirds
The cost of her new bracelet. The cost of her old
bracelet is $18. Need help what Is this solution
Answer:
the answer is $12
Step-by-step explanation:
to get the answer you would multiply 18 by 2/3 or you can divide by 3 then multiply what you get from dividing by 3 by 2.
version 1: 18(2/3) = ?
12
version 2: 18/3=?
6 you want to multiply by to because that is 1/3 of the original price
6(2) = 12
Either way you get the same answer. Hopes this helps
16x2 - 8x + 1 is an example of a ______
Answer:
the answer would be an equation
2. Write a quadratic equation with roots (-2,0) and (4,0) that has a minimum value
of -36
Answer:
f(x) = 4*(x+2)*(x-4) factorized formula
f(x) = 4x^2 - 8x - 32 polynomical formula
Step-by-step explanation:
Lets assume the factorized formula of a quadratic function:
f(x) = a*(x-x1)^2 * (x-x2)^2
where "a" is a coefficient and x1, x2 are the roots of the function. Then replacing the given roots:
f(x) = a*(x+2)*(x-4)
because its told us that -36 is the minimum value of the function we can say that its concave, then this value is actually the component in the Y axis of the vertex. To find the component in the X axis of the vertex we have to make the adding between the roots and divide this value by 2, this last is because a quadratic function is a symetrical function. Lets call the component at the X axis of the vertex as Xv, then:
Xv=(x1+x2)/2
Xv=(-2+4)/2
Xv=1
Therefore now we have a point of the function and its P=(1,-36) this point is the vertex of the function too.
Now the last thing to do is to find the value of the coefficient "a". We can find it by replacing the point of the vertex obtained before.
-36 = a*(1+2)*(1-4)
-36 = a*(3)*(-3)
-36 = a*(-9)
4 = a
Finally the equation is:
f(x) = 4*(x+2)*(x-4)
if we expand this function we find the polynomical form of this function
f(x) = 4x^2 - 8x - 32
