Solve ax + b = cx + d for x.
(Hint: Use the distributive property, where ax + bx = x(a + b).)
Answer: X = (d-b) / (a-c)
This way this worded is weird but I think I got it
Step-by-step explanation:
Subtract B from both sides
ax = cx +d -b
Then subtract CX from both sides
ax -cx =d-b
Distributive Property
x(a-c) =d-b
Divide both sides by a-c
X = (d-b) / (a-c)
Let f(x) = StartFraction x squared minus 5 x + 4 Over x minus 1 EndFraction and g(x) = 2 Superscript x minus 3. For which value of x does f(g(x)) have a discontinuity?
9514 1404 393
Answer:
x=1
Step-by-step explanation:
The function f(x) is undefined where its denominator (x+1) is zero. That will be the case for x=-1.
The composition f(g(x)) will give f(x) an argument of -1 when g(x) = -1. That will be the case when ...
2^x -3 = -1
2^x = 2 . . . . . add 3
x = 1 . . . . . . match exponents
f(g(x)) will have a discontinuity at x = 1.
Answer:
x=1

Answer:
1/7 km long
Step-by-step explanation:
The area of a square is any given one of the sides, squared. We can take this information and apply it to this problem. If the area is 1/49 km squared, we can take the square root of this to find the length of each side.
The square root of 1 is 1, and the square root of 49 is 7, so the answer is 1/7 km for each side.
If you have any further questions, let me know!

Answer:
false
Step-by-step explanation:
the variable x is used in slope intercept
Answer:
False
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )

Answer:
b= 47°
Step-by-step explanation:
the value of a straight line is 180°. so create an equation that sets the angle values to equal 180°, then solve for b:
(3b-6)+(b-2)=180
3b-6+b-2=180
4b-8=180
4b=188
b=47
The Super Bowl half time show lasts 30 minutes. If the half time show is 1/7 of the total game time, how many hours is the Super Bowl from start to finish? Write your answer as a mixed number.
Answer:
3 1/2 hours.
Step-by-step explanation:
If the Half Time show is one-seventh of the show and lasts for 30 minutes, we can multiply that by 7 to get the total amount of minutes.
30 x 7 = 210
To convert the number of minutes to hours, 210 can be divided by 60 to result in a total of 3.5, therefore, the Super Bowl lasts for 3 1/2 hours.

Solving Two Step Equations
r/3 - 6 = -3
Answer:
r = 9
Step-by-step explanation:
r/3 - 6 = -6
First, you need to add 6 on both sides to isolate r/3:
r/3 = 3
Then, you need to multiply both sides by 3 to get r alone:
r = 9
r is 9
-8/11=12/v (solve for v)
Answer:
-8/11=12/v
-8v / 11 = 12
-96v / 11 = 12
-96v = 132
v = 132 / -96
v = 1.375 OR
v = 1 3/8

A cube has a volume of 216cm/3.what is the area of the base of the cube
Answer: 36 cm^2
Step-by-step explanation:
Hello!
We can start by finding the cube root of 216, which is 6. This is the length of each side of the cube.
Now, the area of the base of the cube is equal to 6^2=36 cm^2.

Hey! Please help! What is the slope of this line? I can't figure out how to read the graph correctly
Answer:
slope = -3
Step-by-step explanation:
The line is declining, which means that it will have a negative slope.
Using the slope formula:
m = (y2 - y1)/(x2 - x1)
Take two points from the graph:
Let (x1, y1) = (0, 2)
(x2, y2) = (2, -4)
m = (y2 - y1)/(x2 - x1)
m = (-4 - 2)/(2 - 0)
m = -6/2
m = -3
Therefore, the slope of the line is -3.
For your reference, attached is an edited screenshot of your given graph where it shows where I got the two points for solving the slope.
which of the following are the coordinatesof point f the image of point f after a rotation of 90 degrees about the origin
Answer:
It should be (3,0)
Step-by-step explanation:
a perpindicular line creates a 90º angle so following those lines makes the 0 on the x axis and since coordinates are x,y it should be (0,3)
