Use the second equation. Replace x with the answer choices and if it equals the y value than that is the answer:
Y = x + 6
-4.5 + 6 = 1.5
The answer would be C. (-4.5,1.5)
Answer:
c(−4.5,1.5) is your answer

The function is defined below g(x)= (x^2+4x-5)/(x^2-7x+12 Find all values of that are NOT in the domain of . If there is more than one value, separate them with commas.
Answer:
3,4.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
In this question:
The function is:
[tex]g(x) = \frac{x^2+4x-5}{x^2-7x+12}[/tex]
In a fraction, the values not in domain are the values for which the denominator is 0.
Find all values of that are NOT in the domain of g.
It will not be in domain if the denominator is 0. So
[tex]x^2 - 7x + 12 = 0[/tex]
That is, a quadratic equation with [tex]a = 1, b = -7, c = 12[/tex]
[tex]\Delta = (-7)^{2} - 4(1)(12) = 49 - 48 = 1[/tex]
[tex]x_{1} = \frac{-(-7) + \sqrt{1}}{2(1)} = 4[/tex]
[tex]x_{2} = \frac{-(7) - \sqrt{1}}{2(1)} = 3[/tex]
The values are 3 and 4, so the answer is 3,4.
In ΔHIJ, the measure of ∠J=90°, the measure of ∠I=72°, and JH = 1.2 feet. Find the length of HI to the nearest tenth of a foot.
Answer:
1.3
Step-by-step explanation:
Looking at the triangle, the first thing we can notice is that it is a right triangle, so we can use trigonometric ratios to solve for missing sides.
The side the problem is asking us to find is leg HI, which happens to be the hypotenuse of triangle HIJ.
We also know one side length: HJ= 1.2 ft, and one angle measure: ∠I=72°.
In these types of problems, there are two trigonometric ratios we can look to:
Sine or sin(x)= opposite/hypotenuseCosecant or csc(x)= hypotenuse/oppositeYou can actually use either of these to solve your problem, but for convenience let's use cosecant.
Cosecant of 72° will be equal to HI (the hypotenuse length) divided by HJ (the length of the opposite leg of angle I) Cosecant of 72° will be equal to HI divided by 1.2 (substitute the given length for HJ)1.05146222424 (plug csc(72°) into a calculator)=HI/1.2 1.05146222424*1.2=HI (multiply each side of the equation by 1.2) HI=1.26175466909 (simplify) HI≈1.3 (round the simplified number to the nearest tenth, as the problem requests)disclaimer: i'm not at all qualified to be teaching trigonometry haha (but i hope this helps you!!)

I don’t understand it’s really confusing. This was due an hour ago please help I’m struggling!
Step-by-step explanation:
What you are dealing with is what we call special right triangles. There are two types of right triangles.
30-60-90 triangle- A special
right triangle with side length ratio as
[tex](a)(a \sqrt{3} )(2a)[/tex]
, where a is any positve number
45-45-90- a special right triangle which side length ratios are
[tex](a)(a)(a \sqrt{2)} [/tex]
where a is any positve number.
45 45 90 triangles is indicated by two congruent side measures( if the legs are congruent and it has a right angle, it is a 45-45-90.
30-60-90 triangles is indicated by a having at least two of the following angles given (30,60, and 90).
Shortcuts:
For a 45 45 triangle,
the legs are equal while the hypotenuse is the sqr root of 2 times than the legs.
Example, look at 1. The legs side length is 12 so our hypotenuse side length will be
[tex]12 \sqrt{2} [/tex]
For a 30-60-90 triangle, the side that is adjacent to the 30 and 90 degree measure sqr root of 3 times more than the horizontal leg.
the slanted side or the side which is adjacent to the 30 and 60 degree angle is twice the length of the horizontal leg or the side that is adjacent to the 60 and 90 degree.
Example, look at 3. We need to find x but we are given the horizontal side so just multiply sqr root of 3 to 12.
[tex]x = 12 \sqrt{3} [/tex]
[tex]1.12 \sqrt{2} [/tex]
2.Both equal
[tex]2.8 \sqrt{2} [/tex]
[tex]3.12 \sqrt{3} [/tex]
4. a=13
[tex]4.13 \sqrt{3} [/tex]
[tex]5.9 \sqrt{4} [/tex]

explain how the following diagram demonstrates the pythagorean theorem?
Answer:
the largest block represents the hypotenuse which would be c² the smallest can either be a or b and the block thats left over will be the letter you didn't use for the small block so in terms the blocks represents a²+b²=c²
[tex]\bold{a^2+b^2=c^2}[/tex] is indeed the Pythagorean theorem. It implies that adding the hypotenuse square as well as the two sides of a right triangle equals the hypotenuse square.
Calculating value by using the Pythagorean theorem:The smallest side of the triangle in this instance contains 36 squares, which equals [tex]\bold{6^2}[/tex]. The triangle's bigger side has 64 (or [tex]\bold{8^2}[/tex]) squares. You get 100 by multiplying 36 and 64, which is the same as [tex]\bold{10^2}[/tex]. Using the formula [tex]\bold{a^2+b^2=c^2}[/tex], you should arrive at [tex]\bold{6^2+8^2=10^2}[/tex].Find out more information about the Pythagorean theorem here:

The ratio of fish to turtles in a pond is
20:3. There are 80 fish in the pond.
How many turtles are in the pond?
A 10
B 14
C 12
D 16
Answer:
12
Step-by-step explanation:
think of the ratio as a fraction. 20/3 if f is 20 and t is 3 then when f is 80 t should be 12 because 20*4 is 80 and 3*4 is 12
=========================================================
Work Shown:
(# of fish)/(# of turtles) = (# of fish)/(# of turtles)
20/3 = 80/x
20x = 3*80 ........ cross multiply
20x = 240
x = 240/20 ....... divide both sides by 20
x = 12
There are 12 turtles in the pond.
Note how the ratio 80:12 reduces fully to 20:3 after dividing both parts by 4.

- HERES A BETTER EXPLANATION: Angle 1 is 140°. You need to find the value of angles, 2, 3, and 4. I’m pretty sure everything should add up to 360°
Answer:
140
Step-by-step explanation:
1 and 3 are vertical angles meaning they are equal. 4 and 3 make a straight angle. A straight angle is 180.
180-140=40
2 and 4 are straight angles so should be equal.
1=140
2=40
3=140
4=40
If AB=4 feet & AD=10 feet & m
What is DC?
What is BD?
What is m
What is m
Answer:
1. DC = AB = 4 ft
2. BD = 10.80 ft
3. m<CED = [tex]90^{0}[/tex]
4. m<EBC = [tex]65^{o}[/tex]
Step-by-step explanation:
From the given quadrilateral,
Given: AB = 4 ft, AD = 10 ft and m<BAE = 65.
1. DC = AB = 4 ft (opposite sides of a parallelogram are equal)
2. Applying the Pythagoras theorem to ΔABD, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]BD^{2}[/tex] = [tex]4^{2}[/tex] + [tex]10^{2}[/tex]
= 16 + 100
= 116
BD = [tex]\sqrt{116}[/tex]
= 10.7703
BD = 10.80 ft
3. m<CED = [tex]90^{0}[/tex] (the diagonals bisects each other at right angle)
4. m<ABC + m<BAC + m<ACB = 180
90 + 65 + m<ACB = 180
m<ACB = 180 - 155
m<ACB = [tex]25^{0}[/tex]
So that,
m<BEC + m<EBC + m<ECB = 180
90 + m<EBC + 25 = 180
m<EBC = 180 - 115
m<EBC = [tex]65^{o}[/tex]

A group of friends wants to go to the amusement park. They have no more than $245 to spend on parking and admission. Parking is $9.25, and tickets cost $25.75 per person, including tax. Which inequality can be used to determine pp, the maximum number of people who can go to the amusement park?
Answer:
25.75x+9.25
Step-by-step explanation:
9.25 is the constant. You multiply the ticket by the amount of people to get ticket cost. Then you add ticket cost 9.25 to get final answer.
Inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We have been given that the group of friends has no more than $245 to spend on parking and admission.
And the parking is $9.25, and tickets cost $25.75 per person, including tax.
Let the number of people would be p who can go to the amusement park,
So the inequality that expresses the relationship is
⇒ 9.25 + 25.75 × p ≤ 245
Therefore, inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

How do I do Angle Measures of Parallel Lines
Answer:
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
