Answer:
y = 2x + 5
Step-by-step explanation:
REMEMBER:
The new line will be parallel to the line represented by y =2x +2⇒ The equation y = 2x + 2 is written in slope- intercept form (i.e. y=mx + b) where m represents the slope. So the slope of this line is 2. A line parallel to y = 2x + 2 will have the same slope. This means the slope of the new line will also be 2.
To determine the equation of the new line, we can use the given point to find the y intercept of the new line:
⇒ y = 2x + b
Use x = -1 and y =3 to find b (or the y intercept ) of the new line:
⇒ 3 = 2 * (-1) + b
⇒ 3= -2 + b
⇒ b=5
Therefore, the equation of the line passing thru (-1,3) with the same slope as that of y = 2x + 2 will be:
⇒ y = 2x + 5
Answer:
y = 2x + 5
Step-by-step explanation:
Given line equation 2x - y + 2 = 0
Equation of line parallel to this line will be of form
=> 2x - y + k = 0 ( where 'k' is a constant )
Now this line passes through (-1,3)
=> 2(-1) - (3) + k = 0
=> -2 - 3 + k = 0
=> k - 5 = 0
=> k = 5
Therefore the required line equation is 2x - y + 5 = 0 or y = 2x + 5
Hope you've understood the solution.

Find (g•f)(3)
f(x) = |x + 2|
g(x)=-x^2
Answer:
-25
Step-by-step explanation:
This question is asking for a composite function.
Let's take this step-by-step!
[tex]f(x) = |x + 2|\\g(x) = -x^2[/tex]
(g•f)(3) means [tex]g(f(3))[/tex]
In English, this means we put 3 into f(x), and use the result for g(x).
First let's do f(x):
[tex]f(3) = |3 + 2| = |5| = 5[/tex]
The lines mean "modulus"/"absolute value" which makes any number positive
For example,
[tex]|-3| = 3[/tex]
[tex]f(3) = 5\\g(f(3)) = g(5)\\g(5) = -(5)^2 = -25[/tex]

Answer:
m<RUS = 65°
m<UST = 15°
Step-by-step explanation:
Hi there!
We are given circle O, with a diameter of US
The measure of arc RU is 50°, and the measure of arc UT is 30°
We want to find the measure of <RUS and <UST
First, let's start with <RUS
As stated before, we were given the diameter of a circle - that is segment US
Notice how ΔRUS (which contains <RUS) contains the diameter US - this means that the portion of the circle that contains ΔRUS is a semicircle.
If that portion is a semicircle, then that means that m<URS is 90°
Next, we know that the measure of arc RU is 50°
Notice how <RSU is an inscribed angle, meaning that it is created by 2 chords, and that its vertex is on the circle itself
Inscribed angles are half the measure of the arcs they intercept. The arc that <RSU intercepts is arc RU, which means that the measure of <RSU is 25°
Now, to find m<RUS, you can do m<URS - m<RSU, as the acute angles in a right triangle add up to 90°
In that case:
m<RUS = m<URS - m<RSU
via substitution, m<RUS = 90° - 25°
m<RUS = 65°
Now we need to find the measure of <UST
Notice how m<UST is also an inscribed angle
The arc it intercepts is arc UT, which we were given has a measure of 30 degrees
Therefore, m<UST = half of the measure of arc UT
Via substitution,
m<UST = 1/2 * 30
m<UST = 15°
Hope this helps!
the Area of the circles
Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:
[tex]\pi r^{2}[/tex]
Our radius is 9 so we substitute this into the equation:
π(9)² = 81π
81π = 254.4 in²
Answer:
254 cm^2.
Explain:
The area of a circle is given by pi r squared. Pi has a constant value of 3.14. And the radius of the circle is 9 cm. The area equals pi R² equals 3.14 × 9² CM squared. 3.14 × 81 = 2.54.34cm^2 equals 254cm^2.

Find the value of x, if C is on line AE
Answer:
x = 11°
Step-by-step explanation:
Linear Pair
Two angles adjacent to each other that form a straight line.
The sum of angles of a linear pair is always equal to 180°.
⇒ m∠C = 180° - 33° = 147°
Alternate Interior Angle Theorem
When two parallel lines are cut by a transversal, the alternate interior angles are congruent.
From inspection of the diagram, we can see that AB ║ DC.
Therefore, AE is the transversal.
So m∠A = 33°
Sum of interior angles of a triangle is 180°
Therefore, the top angle of the triangle = 180° - m∠A - 2x
= 180° - 33° - 2x
= 147° - 2x
Angles around a point add up to 360°
⇒ 33° + m∠C + 5x + (147° - 2x) = 360°
⇒ 33° + 147° + 5x + 147° - 2x = 360°
⇒ 327° + 3x = 360°
⇒ 3x = 33°
⇒ x = 11°
Answer:
x = 11°
Explanation:
m∠C = m∠A = 33°m∠B = 2(x)m∠I = 180° - 5(x)============ [ total interior angle in a triangle is 180° ]
solve for x
33° + 2(x) + 180° - 5(x) = 180°-3(x) = 180° - 213°-3(x) = -33°x = 11°The side lengths in yards of a triangle and a square are shown in the diagram. The perimeter of the triangle is equal to the perimeter of the square. What is the value of x?
The value of x given the perimeter of the square is 6.
What is the value of x?The first step is to determine the perimeter of the square.
Perimeter of the square = 4 x length
4 x 2.5x = 10x yards
The perimeter of the triangle is equal to the sum of the three side lengths
2x + 4x - 2 + 2x + 14 = 10x
Combine similar terms
14 - 2 = 10x - 2x - 4x - 2x

The function h(t) = -2(t - 3)2 + 23 represents the height, in feet, t seconds after a volleyball is
served. Which of the following statements are correct? Select all that apply.
The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball wag 23 feet.
If the volleyball is not returned by the opposing team, it will hit the ground in 5.5 seconds.
The graph that models the volleyball's height over time is exponential.
The volleyball was served from a height of 5 feet.
Answer:
1,2, and 5
Step-by-step explanation:
The statements about the function that are correct are:
The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball was 23 feet.
We have,
The function h(t) = -2(t - 3)2 + 23 represents the height, in feet, t seconds after a volleyball is served.
Let's analyze each statement:
The volleyball reached its maximum height at 3 seconds.
This statement is correct.
The function h(t) is a quadratic function, and its graph is a parabola that opens downwards.
The vertex of the parabola represents the maximum height of the volleyball.
In this case, the vertex occurs when t = 3 seconds.
The maximum height of the volleyball was 23 feet.
This statement is also correct.
We can see from the function that the maximum height occurs at t = 3 seconds, and substituting t = 3 into the function gives:
h(3) = -2(3 - 3)2 + 23 = 23 feet.
If the volleyball is not returned by the opposing team, it will hit the ground in 5.5 seconds.
This statement is incorrect.
To find when the volleyball hits the ground, we need to find when h(t) = 0. Solving -2(t - 3)2 + 23 = 0 gives t = 3 ± √(23/2).
Since the vertex is at t = 3 seconds, the volleyball will hit the ground at the same height it was served, which is h(0) = -2(0 - 3)2 + 23 = 5 feet.
So the time it takes for the volleyball to hit the ground is when h(t) = 0, which occurs at t = 3 ± √(23/2), not 5.5 seconds.
The graph that models the volleyball's height over time is exponential.
This statement is incorrect.
The function h(t) is a quadratic function, not an exponential function.
The volleyball was served from a height of 5 feet.
This statement is also incorrect.
The function h(t) gives the height of the volleyball above the ground, not above the height it was served.
However, we can see from the function that h(0) = -2(0 - 3)2 + 23 = 5 feet, so the volleyball was served from a height of 5 feet above the ground.
Thus,
The statements about the function that are correct are:
The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball was 23 feet.

Step-by-step explanation:
Given:
[tex]\displaystyle \large{9|x-8| < 36}[/tex]
Divide both sides by 9:
[tex]\displaystyle \large{|x-8| < 4}[/tex]
Theorem:
For [tex]\displaystyle \large{|x-a| < b}[/tex], since absolute is less than a constant, the interval or solution is:
[tex]\displaystyle \large{-b < x-a < b}\\\displaystyle \large{-b+a < x < b+a}[/tex]
Therefore:
[tex]\displaystyle \large{|x-8| < 4 \to -4 < x-8 < 4}\\\displaystyle \large{-4+8 < x < 4+8}\\\displaystyle \large{4 < x < 12}[/tex]
Therefore, the solution is 4 < x < 12
Answer:
4 < x < 12
Step-by-step explanation:
9|x - 8| < 36
Divide both sides by 9:
|x - 8| < 4
Solution 1
(x - 8) < 4
Add 8 to both sides:
x < 12
Solution 2
-(x - 8) < 4
-x + 8 < 4
Subtract 8 from both sides:
-x < -4
Divide both sides by -1 (remembering to change the direction of the sign):
x > 4
Therefore, the solution to the inequality is 4 < x < 12
