Answer:
4a + 4b - 2
Step-by-step explanation:
To evaluate h(a + b) , substitute x = a + b into h(x), that is
h(a + b) = 4(a + b) - 2 = 4a + 4b - 2

4 (x-1)^2=96
Answer:
2√6 + 1
Step-by-step explanation:
Given expression:
4(x-1)² = 96
Solving by square root;
Square root both sides;
[tex]\sqrt{4(x-1)^{2} }[/tex] = √96
√4(x-1)² = √6x16
√4(x-1)² = 4√6
2(x-1) = 4√6
Divide both sides by 2;
x-1 = 2√6
Add 1 to both sides;
x = 2√6 + 1

What is the measure of Zx in the diagram shown below?
A
23°
B
33°
С
113°
157°
Answer:
Since that is a right angle it is going to equal 90 degrees. Since you know that the first angle is 67 degrees subtract 67 from 90 and get 23 degrees.
Step-by-step explanation:
plz help me on this question
Answer:
[tex]\boxed {129\textdegree}[/tex]
Step-by-step explanation:
Both angles labeled, are actually Supplementary Angles (which two angles that add up to [tex]180\textdegree[/tex]). So, to find the missing measurement of an angle, which is the angle labeled in [tex]x[/tex], you need to take [tex]51\textdegree[/tex] and subtract it from [tex]180\textdegree[/tex] to get the missing angle measurement:
[tex]180\textdegree - 51\textdegree[/tex]
[tex]\boxed {129\textdegree}[/tex] (angle measurement for the angle labeled in [tex]x[/tex])

Steph bought a used bicycle, restored it, and then marked it up 1/4 of the price she paid. Later she sold it for the marked up price $80. How much, in dollars did Steph pay for the bicycle
Price she paid, P = $80 .
She sells the bicycle at 1/4 of the price she paid.
Let, buying price is x.
So, as given in question selling price will be x/4.
Also, selling price is given as $80 .
[tex]\dfrac{x}{4}=80\\\\x = \$320[/tex]
Therefore, Steph pay $320 for the bicycle.
Hence, this is the required solution.
Find three consecutive odd integers such that the sum of 7 times the smallest and twice the largest is -91.
A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.
In that function, which variable is independent? Which one is dependent?
Type your response in the space below.
Answer:
Independent variable = the time. Dependent variable = amount of water per minute
Step-by-step explanation;
The total amount of water depends on how long the hose is left on.
The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
Time is the independent variable.
The amount of water per minute is the dependent variable.
Given
A parent is using a garden hose to fill up a small inflatable pool for her young child.
The pool has a capacity of 90 gallons.
She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.
What is the independent variable?Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable?A change in the independent variable directly causes a change in the dependent variable.
1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
2. Time is the independent variable.
3. Amount of water per minute is the dependent variable.

6y+4−3y−7=3(y−1) How many solutions are for this?
Answer:
Infinite amount of solutions.
General Formulas and Concepts:
Order of Operations: BPEMDASRegular + Equality PropertiesStep-by-step explanation:
Step 1: Define equation
6y + 4 - 3y - 7 = 3(y - 1)
Step 2: Solve for y
Combine like terms: 3y - 3 = 3(y - 1)Distribute 3: 3y - 3 = 3y - 3Subtract 3y on both sides: -3 = -3Here we see that there will be infinite amount of solutions. We can plug in any number y and it will render the equation true.

What's A Angle Bisector And A Bisector?
Answer:
Bisection
In geometry, bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector. The most often considered types of bisectors are the segment bisector and the angle bisector.
Angle Bisector
The (interior) bisector of an angle, also called the internal angle bisector (Kimberling 1998, pp. 11-12), is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.
