Which equation in standard form has a graph that passes through the point (8,29) and has a slope of 5/2
Answer:
The equation is y = (5/2)x + 9
Step-by-step explanation:
We look for an equation with the form y = mx + b, where m is the slope and b the y-intercept.
We're given the slope, (5/2) which we can use for m:
y = (5/2)x + b
We are told the line goes through (8,29). We need a value of b that will move the line to include this point. Do that by substituting the values:
x = 8, and y=29
y = (5/2)x + b
29 = (5/2)*8 + b
29 = (20) + b
9 = b
The equation is y = (5/2)x + 9

2.3.3 congruent triangles
In the congruent triangles both triangle are same . In this triangle 2.3.3 congruent triangle image given below to understand better.
According to the question, given that
2.3.3 congruent triangle under congruence triangle are explain:
Both triangles are said to be congruent if the three angles and three sides of one triangle match the corresponding angles and sides of the other triangle. We can see from the examples PQR and XYZ that PQ = XY, PR = XZ, and QR = YZ, and thus P = X, Q = Y, and R = Z. Then, we can state that XYZ and PQR.
To be congruent, the two triangles must be the same size and shape. It is necessary for both triangles to be superimposed on one another. A triangle appears to be in a different place or have a different look as we rotate, reflect, and/or translate it.
Two triangles must meet five requirements in order to be congruent. The congruence properties are SSS, SAS, ASA, AAS, and RHS.
SSS Congruence Criteria
Side-Side-Side criterion is referred to as the SSS criterion. According to this standard, two triangles are congruent if their respective triangles' three sides are equal to one another.
The three angles of BAC must be identical to the corresponding angles of XYZ if, according to the SSS condition, BAC XYZ.
SAS Congruence Criteria
Side-Angle-Side criterion is referred to as the SAS criterion. According to this standard, two triangles are said to be congruent if their matching sides and included angles are the same on each side of each other.
The third side (AB) and the other two angles of ABC must be identical to the equivalent side (XY) and the angles of XYZ if ABC XYZ under the SAS condition.
ASA Congruence Criteria
Angle-Side-Angle criterion is also known as ASA criterion. According to the ASA criterion, two triangles are congruent if any two of their included sides and related angles are equivalent in size to those of the other triangle.
AAS Congruence Criteria
Angle-Angle-Side criterion is also known as the AAS criterion. Two triangles are said to be congruent according to the AAS criterion if any two angles and the non-included side of one triangle match the corresponding angles and side of the second triangle.
RHS Congruence Criteria
Right angle-hypotenuse-side congruence is referred to as the RHS criterion. If the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, then two triangles are said to be congruent according to this criterion.

5) How can we guarantee that a polynomial is not a perfect square, considering just the constant term? For instance, in 4, the constant term is -121, in 2, the constant term is 36. Which of them cannot be a perfect square and why, based only on the constant term?
Polynomials with a negative constant term are not perfect squares, hence polynomial 4, with constant term of -121, is not a perfect square.
What are perfect square expressions?Perfect square expressions are formed in two ways, either with the square of the sum or the square of the subtraction, as follows:
Square of the sum: (a + b)² = a² + 2ab + b².Square of the subtraction: (a - b)² = a² - 2ab + b².The constant term is the final term. Since this term is squared, it will always be positive for perfect squares, hence if the constant term is negative, it will guarantee that the polynomial is not a perfect square.
For the expressions in this problem, we have that:
The expression with a constant term of 36 can be a perfect square, as 36 is a positive number.The expression with a constant term of -121 cannot be a perfect square, as -121 is a negative number.More can be learned about perfect squares at https://brainly.com/question/14584348

Answer:
v = 61
Step-by-step explanation:
Hello, of course! These are vertical angles, which means they're equal to each other, so let's set up an equation, shall we? (:
Knowing that they're equal to each other, both sides of the equation should be equal to each other as well, so...
2v + 1 = 123
Now, that we have the equation, we must solve for the variable v!
2v + 1 = 123
- 1 - 1
2v = 122
2v = 122
2 2
v = 61
Therefore, v is 61. Once again, vertical angles are equal to each other, so you set up the equation, where both sides are equal. Hope this helped and best of luck with the rest of your work! <3

In any triangle, the segment joining the mid-points of two sides is parallel to the third side and equal to half its length
B is the mid-point of RS
C is the mid-point of RT
BC = 1/2 ST
BC = x + 19
ST = x + 29
x + 19 = 0.5(x + 29)
x + 19 = 0.5(x) + 0.5(29)
x + 19 = 0.5x + 14.5
Subtract 0.5x from both sides
x - 0.5x + 19 = 0.5x - 0.5x + 14.5
0.5x + 19 = 14.5
Subtract 19 from both sides
0.5x + 19 - 19 = 14.5 - 19
0.5x = -4.5
Divide both sides by 0.5

7. Here is an inequality: -7- (3x+2) <-8(x + 1)
Select all the values of x that are solutions to the inequality.
A. x = -0.2
B. x = -0.1
C.x=0
D. x = 0.1
E. x = 0.2
F. x = 0.3
(From Unit 2, Lesson 19.)
Answer:
A,B,C,D
Step-by-step explanation:
-7-(3x+2) <=8(x+1)
-7-3x-2<-8x-8
5x<1
x<1/5
x= -0.2, X=-0.1, X=0, X=0.1
The values of x that are solutions to the inequality are C (x = 0) and D (x = 0.1).
Given inequality: -7 - (3x + 2) < -8(x + 1)
Let's solve the inequality step by step:
Distribute the -8 on the right side:
-7 - 3x - 2 < -8x - 8
Combine like terms on both sides:
-9 - 3x < -8x - 8
Add 8x to both sides to isolate the variable terms on one side:
8x - 3x - 9 < -8
Simplify the left side:
5x - 9 < -8
Add 9 to both sides:
5x < 1
Divide both sides by 5 (since 5 is positive, the direction of the inequality does not change):
x < 0.2
Now, let's compare the solutions to the given options:
A. x = -0.2: Not a solution (not less than 0.2)B. x = -0.1: Not a solution (not less than 0.2)C. x = 0: Solution (0 is less than 0.2)D. x = 0.1: Solution (0.1 is less than 0.2)E. x = 0.2: Not a solution (not less than 0.2)F. x = 0.3: Not a solution (not less than 0.2)So, the values of x that are solutions to the inequality are C (x = 0) and D (x = 0.1).

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
a) Yes; Machine A and Machine B make 77.5 ounces in 10 minutes. 77.5 > 72, so there will be enough popcorn.
b) Yes; Machine A and Machine B make 87.5 ounces in 10 minutes. 87.5 > 72, so there will be enough popcorn.
c) No; Machine A and Machine B make 67.5 ounces in 10 minutes. 67.5 < 72, so there will not be enough popcorn.
d) No; Machine A and Machine B make 30.75 ounces in 10 minutes. 30.75 < 72, so there will not be enough popcorn.
If each machine makes popcorn for 10 minutes, there will be enough popcorn as machine A and machine B make 87.5 ounces in 10 minutes.
According to the question,
We have the following information:
Machine A makes 12.75 ounces of popcorn in 3 minutes.
So, we will find the ounces of popcorn in 1 minute:
3 minutes = 12.75 ounces
1 minute = 12.75/3 ounces
1 minute = 4.25 ounces
So, in 10 minutes machine A will make:
10 minutes = (4.25*10) ounces
10 minutes = 42.5 ounces
Machine B makes 18 ounces of popcorn in 4 minutes.
So, we will find the ounces of popcorn in 1 minute made by machine B:
4 minutes = 18 ounces
1 minute = 18/4 ounces
1 minute = 4.5 ounces
So, in 10 minutes machine B will make:
10 minutes = (4.5*10) ounces
10 minutes = 45 ounces
Now, the total amount of popcorn made by both the machines will be:
Popcorn made by machine A in 10 minutes + Popcorn made by machine B in 10 minutes
42.5 + 45
87.5 ounces
Now, the eight 9-ounce bags mean that there will be 72 ounces of popcorn.
So, we have:
87.5 ounces is greater than 72 ounces.
Hence, the correct option is B.
