A common denominator, which means having the same number in the denominator (or the bottom) of each fraction, creates equivalent fractions that can be added, subtracted, or compared. Finding a common denominator means finding one number that each denominator can divide into easily.

Solve the inequality -3/4x + 6 > -3.
Use the Remainder Theorem to find the
remainder when dividing f(x) = 4x^3 - 2x^2 + 7x - 1
by x - 1.
Answer:
f(1) = 8
Step-by-step explanation:
x - 1 = 0
x = 1
f(x) = 2x² + 7x - 1
f(1) = 2*1² + 7*1 - 1
= 2 + 7 - 1
= 9 - 1
f(1) = 8

What is the domain of the function y=3/x?
O
-00
O 0
0
1
Answer: Choice A) [tex]-\infty < x < \infty[/tex]
We can plug in any x value we want. The domain is the set of all real numbers. We don't have to worry about applying the square root of a negative value since negative values are allowed in cube roots.
For instance, [tex]\sqrt[3]{-64} = \sqrt[3]{(-4)^3} = -4[/tex]

Answer:
16: y=4x+14 17: 12 18: when you simplify it all individually you get x=3 for both equations. 19: $6.69
Step-by-step explanation:
16:y-2=4(x+3) distribute 4 and get y-2=4x-12. Add 2 to both sides to get y-4x+14.
17:x+2y=4 and 3x+6y=? divide 3x+6y by three and you get x+2y=4. This means you can just multiply the 4 by 3 to get the answer.
18:3x-5=4 and 3x-3=6. For the first one add 5 to both sides to get 3x=9 then divide both side by 3 to get x=3. For the second one add 3 to both sides to get 3x=9. Again divide both sides by three to get x=3.
19: $18-$4.62=13.38 since he wants 2 models divide 13.38 by 2 to get 6.69.

Solve for z. –z + 4= -4
Answer:
-z+4=-4
Step-by-step explanation:
First, you want to move the positive four to the other side to isolate the variable.
-z=-8
You cannot have a negative variable, so divide both sides by 1.
-z/1=-8/1
Your answer would be:
Z=8

Jim’s backyard is rectangular with dimensions of 75 feet by 120 feet. He is planning to designate part of the yard to plant a vegetable garden. The garden will be a similar rectangle, using a scale factor of 2/5. How much fencing will he need if he wants to enclose the garden on all four sides?
Answer:
He will need 99 feet of fence.
Step-by-step explanation:
Jim's back yard has the following dimensions;
Length=120 feet
Width=75 feet
The gardens dimensions can be calculated using the expression;
Length of garden=Length of back yard/scale factor
where;
Length of back yard=120 feet
Scale factor=2/5
replacing;
Length of garden=120/2/5
Length of garden=12 feet
Width of garden=Width of back yard/scale factor
where;
Width of back yard=75 feet
Scale factor=2/5
replacing;
Width of garden=75/2/5
Width of garden=37.5 feet
The gardens dimension are;
Garden width=37.5 feet
Garden length=12 feet
To get the length of the fence that will enclose all four sides, we calculate the perimeter of the garden;
Perimeter=2(length+width)
Perimeter=2(12+37.5)=99 feet
He will need 99 feet of fence
Answer:
he will need 99 feet to fence
Step-by-step explanation:
Jim's back yard has the following dimensions;
Length=120 feet
Width=75 feet
The gardens dimensions can be calculated using the expression;
Length of garden=Length of back yard/scale factor
where;
Length of back yard=120 feet
Scale factor=2/5
replacing;
Length of garden=120/2/5
Length of garden=12 feet
Width of garden=Width of back yard/scale factor
where;
Width of back yard=75 feet
Scale factor=2/5
replacing;
Width of garden=75/2/5
Width of garden=37.5 feet
The gardens dimension are;
Garden width=37.5 feet
Garden length=12 feet
To get the length of the fence that will enclose all four sides, we calculate the perimeter of the garden;
Perimeter=2(length+width)
Perimeter=2(12+37.5)=99 feet
He will need 99 feet of fence

If TUV is isosceles, find the value of X
Answer:
x = 17
Step-by-step explanation:
Since the triangle is isoceles that means angle UTV is also 43 degrees. The sum of all angles in a triangle is 180 degrees. So construct this equation. 43 + 43 + 43 + 8x - 42 = 180. Now solve for x.
