Let's solve for v :
[tex] - 19 = - 14v + 14v[/tex]here, the the terms associated with v, that us -14v and 14v gets cancel out, so there's no solution for v and hence it's value can't be determined.

At the Richard's pound the ratio of cats to dogs is 9 to 6. If there are 45 cats in the pound then
how many dogs are in the pound?
Answer:
30 dogs are in the pound.
Step-by-step explanation:
If the original ratio is 9:6
Then multiply both sides by 5: (9*5) : (6*5)
New ratio: 45:30

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length. The length of a rectangle is 23 feet more than the width. If the perimeter is 70 feet, then what is the length of the rectangle, in feet?
Answer:
Length = 6 + 23 = 29 feet
Step-by-step explanation:
Width = x
Length = x + 23
2x + 2(x+23) = 70
2x + 2x + 46 = 70
4x = 70-46
x = 24/4
x = 6
Kylee is making a cake. The box says for every 1/4 cup of water she needs to use 2/4 of the cake mixture. She uses 3 1/4 cups of water. How much cake mixture does she use? (show your answer as a decimal and as a fraction.)
Answer:
Kylee makes 6 1/2, or 6.5 cups of the cake mixture.
Step-by-step explanation:
She uses double the cake mixture as water. She uses 3 1/4 cups of water, or 13/4 as an improper fraction, so she uses double that of cake mixture, which is 6 1/2, or 26/4 cups of cake mixture.
As a decimal that is 6.5.
Answer the question below
f(x) =2x+1 g(x)= x^2 -7 find (f+g)(x)
Answer:
[tex]f(x) = 2x + 1 \\ g(x) = {x}^{2} - 7 \\ (f + g)(x) = f(x) + g(x) \\ (f + g)(x) = (2x + 1) + ( {x}^{2} - 7) \\ (f + g)(x) = 2x + 1 + {x}^{2} - 7 \\ \boxed{ (f + g)(x) = {x}^{2} + 2x - 6}[/tex]
(f+g)(x) = x²+2x-6 is the right answer.what type of mathematical law is this (6+4)+100=6+(4+100)
Answer:
Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition: when three real numbers are added, it makes no difference which two are added first.
a + (b + c) = (a + b) + c
Therefore, in the given equality statement: (6 + 4) + 100 = 6 + (4 + 100), the sum of the numbers on either side of the equation will have the same results.
(6 + 4) + 100 = 6 + (4 + 100)
(10) + 100 = 6 + (104)
110 = 110

If
f(x) = x - 5
and
g(x) = 4x – 2
-
Find
f(g(x)) = 4x – [?]
-
Answer:
4x - 7
Step-by-step explanation:
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x)
= f(4x - 2)
= 4x - 2 - 5
= 4x - 7

Find the value of x
solving steps
Answer:
x = 8
Step-by-step explanation:
Supplementary angles add up to 180 degrees to make a straight line.
The red square in one of them indicates that it is 90 degrees on their side which means that it is 90 degrees on the other where (6x+2) and 40 degrees are.
(6x+2) + 40 = 90
6x + 42 = 90
6x = 48
x = 8

Determine the coordinates of A(2,3) after a reflection in the line y=2
Answer:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection)

A frog leaps off of a ledge and lands on the ground below. The function
f(x) = -1.6x2 + 2.3x + 3.2 represents the frog's path.
a. How high is the ledge where the frog starts?
b. How high is the frog at its highest point?
c. What is the frog's horizontal distance from the ledge when it
reaches its highest point?
Answer:
-1.6x2 + 2.3x + 3.2 = f(x) to solve this you do -1.6 x 2 = -3.2 + 2.3x = -0.9 + 3.2 = 2.3
Step-by-step explanation:
For A the height of ledge is 3.2
for b - the frogs highest point 2.30x
and c is 12.3x
Below are two parallel lines with a third line intersecting them 107
Answer:
x° = 107°
Step-by-step explanation:
Given that m < 107° and m < x° are alternate interior angles that do not have a common vertex on alternate sides of the transversal, then it means that they have the same measure. It also implies that their supplements will have the same measure, 73°.
Therefore, x° = 107°.

107
Step-by-step explanation:
they r on opposite sides so they are the same.
Given f(x) = x^2+9x+18 and g(x)=x+6
Find f(x)-g(x)
Answer:
x = -6, -2
Step-by-step explanation:
x^2 + 9x + 18 - (x + 6)
x^2 + 9x + 18 -x - 6
x^2 + 8x + 12
(x+6)(x+2)
x = -6, -2
