hich statement best describes a graph of paired points that form a proportional relationship?
Answer:
A. A straight line can be drawn through all the points and the line passes through the point (0,0) .
Step-by-step explanation:
See comment for options
Given
A graph with proportional relationship
Required
Which of options (a to d) describes the graph
A graph with a proportional relationship is represented as:
[tex]y = kx[/tex] and
[tex](x,y) = (0,0)[/tex] is a paired point on the graph
This implies that options (b) and (c) are not true
Option (d) is also incorrect because if the graph does not pass through all points, then it is not proportional.
Hence, (a) is correct

3(p + 5) and 7p - 4p + 15
Options A and C are the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
3p + 15
Taking out common factors.
3 (p + 5) ____(1)
And,
7p - 4p + 15
3p + 15
3(p + 5) _____(2)
From (1) and (2),
3(p + 5) and 7p - 4p + 15 are equivalent expression.
Thus,
The equivalent expressions are:
3(p + 5) and 7p - 4p + 15

Dominic is going to attend a baseball game on Saturday afternoon. He has a total of $40 he can spend. The ticket cost is $22, and the parking cost is $7. He intends to spend his remaining money on team window decals that cost $4.50 each. What is the greatest number of decals Dominic can buy? A 2 decals B 3 decals C 4 decals D 5 decals
Answer: A. 2 Decals
Step-by-step explanation: time4learning
The requried Dominic can buy a maximum of 2 decals.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Dominic has $40 to spend, and he will spend $22 for the ticket and $7 for the parking. So, he will have:
$40 - $22 - $7 = $11
left to spend on team window decals.
Each decal costs $4.50, so we can divide the amount Dominic has left by the cost of each decal to find the maximum number of decals he can buy:
$11 ÷ $4.50 ≈ 2.44
Since we can't buy a fraction of a decal, we need to round down to the nearest whole number. So, Dominic can buy a maximum of 2 decals.
Therefore, the answer is A, 2 decals.

An equilateral triangle means all sides are the same.
ABCD is a square and triangle DEF is equilateral. Triangle ADE is isosceles with AD=AE calculate size of angle AEF
Answer:
∠AEF = 90°
Step-by-step explanation:
The size of angle AEF is given below:
Given that
ABCD is Square
CDF is a straight line
∠ADF = 90°
And triangle DEF is an Equilateral Triangle
So,
∠FDE = 60°
Now
∠ADE = 90° - 60°
= 30°
AD = AE
∠AED = 30°
∠DEF = 60° because of an equilateral triangle
Now
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°

It used another 1/8 of a tank during the third week. A delivery of ½ tank was made at the end of the third week. The final fuel gauge shows a line between ½ and F. How much fuel did the business start with?
Answer:
The business started with 23/24 of their tank full

What are the y-intercept and axis of symmetry of this quadratic function? 5 Select two answers: one for the y-intercept and one for the axis of symmetry
Answer:
y intercept: (0,1)
Axis of symmetry: x=-2
Step-by-step explanation:
The y intercept is where the curve crosses the y axis.
y intercept: (0,1)
The axis of symmetry is the x value where drawing a vertical line has the left side of the curve a mirror image of the right side of the curve.
Axis of symmetry: x=-2
The required y-intercept is (0, 1) and the axis of symmetry is x = -2. Options A and C are correct.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
From the above definition in the graph locate the value of y when x is zero,
So, in the graph, when x is zero y is 1
There is why the y-intercept of the given function is 1,
Now,
For the axis of symmetry, just draw a line with a vertex that part the function in two equal halves,
So vertex of the given function is (-2, -3), and the line that divides the function in two equal halves is x = -2
Thus, Options A and C are correct.

10 laps around track each day. Each lap around the track is 400 meters. How many day will take kali to run a total 12 kilometers
Answer:
3 days
Step-by-step explanation:
First, let's convert 400 meters to km (kilometers):
To find km from m we divide the meters by 1000:
400/1000 = 0.4
Therefore, there are 0.4 km in 1 meter.
Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:
(10)(0.4) = 4
Kali runs 4 kilometers every day
Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4
12/4 = 3
It will take Kali 3 days to run a total of 12 kilometers.

Find three consecutive even integers such that four times
the first minus the third is six more than twice the second.
Answer:
simple just follow me and mark it brainliest
Step-by-step explanation:
LET THE THREE CONSECUTIVE EVEN INTEGERS BE
(x+2) ,(x+4) ,(x+6)
then
according to the question
4(x+2) – (x+6) = 2(x+4) + 6
4x + 8 – x – 6= 2x + 8+6
3x +2 = 2x + 14
3x – 2x= 14 –2
x= 12
the numbers are
14
16
18
Answer:
The three numbers are 14, 16, 18.
Step-by-step explanation:
Consecutive even integers differ by 2.
You can let the smallest of the three numbers equal x. Then the other two numbers are x + 2 and x + 4.
Now use x, x + 2,and x + 4 to represent the 3 numbers and follow the directions to write an equation. The equation will have only one variable, x, so you can solve for x.
"four times the first" -----> 4x
"minus the third" -------> -(x + 4)
"is" -----> =
"six more than twice the second" ------> 2(x + 2) + 6
Put all the pieces in boldface together to arrive at your equation.
4x - (x + 4) = 2(x + 2) + 6
Simplify the parentheses on both sides by distributing.
4x - x - 4 = 2x + 4 + 6
Combine like terms on both sides.
3x - 4 = 2x + 10
Subtract 2x from both sides.
x - 4 = 10
Add 4 to both sides.
x = 14
The smallest number is 14.
x + 2 = 14 + 2 = 16
x + 4 = 14 + 4 = 18
Answer: The three numbers are 14, 16, 18.

7/8 - 1/12 its a math question
Answer:
19/24 = 0.791666667
Step-by-step explanation:
7/8 - 1/12
Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.
21/24 - 2/24
Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.
21 - 2 / 24
Subtract 2 from 21 to get 19.
19/24
