Answer:
x=10
Step-by-step explanation:
set the 2 equations equal to each other
25=2x+5 -> subtract 5
20=2x -> divide by 2
10=x ->answer!
Hope that helps!
Answer:
x = 10
Step-by-step explanation:
f(x) equals both 25 and 2x + 5, so set the equations equal to one another and solve for x.
2x + 5 = 25
2x = 20
x = 10
Plug in what you got for x to check if it is right
2(10) + 5 = 25
20 + 5 = 25
25 = 25

The graph of y=x^2 is the solid black graph below. Which function represents the dotted graph?
Answer:
y=(x-5)^2-4
Step-by-step explanation:
this is because the -4 drops it below the line and then x-5^2 stays where it is so mainly the minus in the domian and range and the -4 moves it over
Find the percent of change from the first value to the second. 72: 81 -
is means "From 72 to 81"*
Answer:
+12.5%
Step-by-step explanation:
This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.
(81 - 72)/72 * 100
Subtract 72 from 81 to get 9
9/72 * 100
Multiply 9 by 100 to get 900
900/72
Simplify the above fraction by cancelling out 9.
100/8
Divide 100 by 8 to get 12.5%
The percent of change is +12.5%

Describe how you know if an equation has NO solutions. Give some examples of an equation that has no solutions.
Answer:
The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur. Use distributive property on the right side first.

The endpoints of a line segment AR are A(8,-2) and R(-4,1). What is the length of the AR?
Answer:
The length of the AR is [tex]3\sqrt{17}[/tex] or [tex]12.4[/tex] units.
Step-by-step explanation:
Given the endpoints of a line segment AR
A(8, -2)R(-4, 1)We can calculate the length of AR using the formula
[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
In our case,
(x₁, y₁) = (8, -2) (x₂, y₂) = (-4, 1)Substituting (x₁, y₁) = (8, -2) and (x₂, y₂) = (-4, 1) in the formula
[tex]L_{AB}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(-4-8\right)^2+\left(1-\left(-2\right)\right)^2}[/tex]
[tex]=\sqrt{\left(-4-8\right)^2+\left(1+2\right)^2}[/tex] ∵ Apply rule: [tex]-\left(-a\right)=a[/tex]
[tex]=\sqrt{12^2+3^2}[/tex]
[tex]=\sqrt{144+9}[/tex]
[tex]=\sqrt{153}[/tex]
[tex]=\sqrt{9\times 17}[/tex]
[tex]=\sqrt{17}\sqrt{3^2}[/tex] Apply radical rule: [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}[/tex]
[tex]=3\sqrt{17}[/tex] Apply radical rule: [tex]\sqrt[n]{a^n}=a[/tex]
[tex]=12.4[/tex]
Therefore, the length of the AR is [tex]3\sqrt{17}[/tex] or [tex]12.4[/tex] units.

2) g(x) = 4x + 1 Find (gºg)(x)
Answer:
Step-by-step explanation:
g circle g (x) has the meaning of putting g(x) on the right wherever you see an x in the original question
gcircle g (x) = 4(g(x)) + 1
g circle g(x) = 4(4x + 1) + 1
g circle g(x) = 16x + 4 + 1
g circle g(x) = 16x+5
The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour. Determine in how many hours the temperature will be 36 degrees Fahrenheit.
The answer is that it would take 8 hours for the temperature to drop down to 36 degrees.
1.5x8=12
1x8=8 and 0.5x8=4
In 8 hours the temperature will be 36°F from 48°F.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, The current temperature is 48 degrees Fahrenheit it is expected to drop 1.5 degrees each hour.
Assuming the no. of hours to be x.
∴ 36 = 48 - 1.5x.
- 1.5x = - 12.
x = 8.

y-intercept 2x-5y=35
Answer:
y=2/5x-7
Step-by-step explanation:
2x−5y=35
Step 1: Add -2x to both sides.
2x−5y+−2x=35+−2x
−5y=−2x+35
Step 2: Divide both sides by -5.
-5y/5=-2x+35/-5
y=2/5x-7

If i'm right, a triangle should add up to 180, so you add 39 and 102 to get 141. Then you subtract 141 from 180 and get 39
Answer:
39
Step-by-step explanation:
Remark
Every triangle has 180 degrees. The three angles must add to 180
Solution
x + 102 + 39 = 180
x + 141 = 180 Subtract 141 from both sides.
x + 141-141 = 180-141
x = 39
