what graph passes the vertical line test?
Students taking an achievement test receive separate scores for the math and verbal sections of the test. The linear model below can be used to predict a student's verbal score, y, based on the student's math score, x.
y = 0.4433x + 307.68
What does the slope of this equation mean in terms of the context of the problem?
Given:
Student's verbal score, y, based on the student's math score, x is
[tex]y=0.4433x+307.68[/tex]
To find:
The meaning of slope of this equation in terms of the context of the problem.
Solution:
Slope intercept form of a linear equation is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
The given equation is
[tex]y=0.4433x+307.68[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=0.4433[/tex]
Therefore, the slope of the linear equation is 0.4433. It means, student's verbal score, y increased by 0.4433 if the student's math score, x increased by 1.
One meaning of the word rigid is "not bendable", and another is "unable to be changed". How do those meanings correspond to the definition of rigid motion?
Answer:
The meaning of rigid corresponds with rigid motion
Step-by-step explanation:
Rigid motion in geometry occurs when a point or object is moved, but the size and shape remain the same. It is also referred to as RIGID TRANSFORMATION.
Therefore, the meaning of the word rigid, which means "not bendable", and another is "unable to be changed" corresponds to the definition of rigid motion.
Rigid means unable to move or remain stagnant.
two thirds plus one fifth
Answer:
0.866666666666666666666666666666666 or 13/15
Step-by-step explanation:
Convert both numbers to fractions and add them together to get 13/15.
The addition of the two-thirds plus one-fifth is 13/15.
What is the addition?The addition of two or more numbers possesses some important properties.
The list of properties of addition given below will help in predicting the sign of the result obtained in the addition process.
The given expression is;
[tex]\rm \dfrac{2}{3}+\dfrac{1}{5}[/tex]
The addition of the expression is determined in the following steps given below.
[tex]\rm = \dfrac{2}{3}+\dfrac{1}{5}\\\\=\dfrac{2 \times 5+3\times 1}{15}\\\\ =\dfrac{10+3}{15}\\\\=\dfrac{13}{15}[/tex]
Hence, the addition of the two-thirds plus one-fifth is 13/15.

Find slope(m) and Y-intercept(b)
Make sure to write in standard form, y = mx + b for each
problem
1. y = 7x + 9
2. y=-5x-2
3. y = 3x + 1
Answer:
1. slope is 7 and y-intercept is 9
2.slope is -5 and y-intercept is -2
3. slope is 3 and y-intercept is 1
Step-by-step explanation:
The standard equation of a line in slope form is;
y=mx + b where m is the slope and b is the y intercept.
In question 1.
y=7x + 9
slope is 7 and y-intercept is 9
In question 2
y= -5x - 2
slope is -5 and y-intercept is -2
In question 3
y= 3x + 1
slope is 3 and y-intercept is 1

A rectangular pool has an area of 5x2 + 23x + 12 and the length of one side is 5x + 3. What is the
length of the other side?
Answer:
x + 4
Step-by-step explanation:
Area of rectangle= length × breadth
In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12
This means that;
5x2 + 23x + 12 = 5x + 3 (b)
Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3
To get the other length, we can factorize the algebraic expression;
5x2 + 23x + 12
Product: 60x^2 (20x × 3x)
Sum: +23x (20x + 3x)
Hence;
= 5x^2 + 20x + 3x + 12
Next, we find factors;
5x (x+4) + 3 (x+4)
Therefore, the factors are (5x + 3) and (x +4)
This means that the other length is (x +4)

Ruth went out to eat with friends. She brought a $50 bill. She bought an appetizer for $8.50, an entree for $13.99, and desert for $6.50. She wants to leave a 20% tip for the good service she received. How much is the tip she will leave? Do not round your answer, but keep in mind that the smallest unit in our financial system is a penny which stops in the hundredths place. *
Answer:
$16.81
Step-by-step explanation:
$50.00 -$8.50 - $13.99 - $6.50 = $21.01
$21.01 * 0.20 = $4.20
$21.01 - $4.20 = $16.81

The rectangle shown is composed of smaller equally-sized squares. The shaded section has an area of 3/16 square inches. Use a unit rate to determine the area of the larger rectangle.
Answer:
Area of larger rectangle = 1½ = 1.5 in²
Step-by-step explanation:
The section consists of 3 small squares that has an area = [tex] \frac{3}{16} in^2 [/tex].
Area of 3 small squares = [tex] \frac{3}{16} in^2 [/tex]
Area of 1 small square = [tex] \frac{3}{16} [/tex] ÷ 3
= [tex] \frac{3}{16} * \frac{1}{3} [/tex]
= [tex] \frac{3*1}{16*3} = \frac{1}{16} [/tex]
The larger rectangle has 24 small squares of equal sizes
Area of larger rectangle = area of 1 small square * 24
= [tex] \frac{1}{16} * 24 [/tex]
[tex] = \frac{24}{16} = \frac{3}{2} [/tex]
Area of larger rectangle = 1½ = 1.5 in²

If a business receives an invoice for services purchased on account on December 1st for $8,000, how much should the business write a check for to pay the invoice in full on December 8th if the terms are 1/10, n/15?
Answer:
The amount that should be written on the check is $7920
Step-by-step explanation:
The explanation of the question is given as:
1/10 = 1% discount to be given if paid within 10 days
n/15 = full amount to be paid within 15 days.
From the question, we can see that:
If the check for the invoice is given on December 8th, it is still within the discount time of 10 days.
Discount amount = $8000 × 1%
= $80
$8000 - $80
= $7920
Hence, the amount that should be written on the check is $7920

Barbara bought 5 amusement park tickets at a cost of $30. If she bought 7 tickets, how much would it cost?
It would cost $
.
Answer:
$42
Step-by-step explanation:
5 divided by $30 so each ticket would be $6 then just multiply $6 and 7
Answer:
It would cost $42 because 30 divided by 5 equals 6, so that's saying for each 1 ticket it costs $6. So with the new equation, 7 x $6, we get $42. Which will end up being the cost for 7 tickets.

I need some help with this problem
Answer:
-6
Step-by-step explanation:
First you need to substitute -1 in for x in -2x^2
This makes it (-2)(-1)^2
-2x^2 becomes -2 so this means that the equation is now
-2 + (-1) - 3
-2 + (-1) = -3
-3 - 3 = -6
