Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster. Which graph represents the set of heights that satisfy this requirement?
A number line going from 50 to 58. An open circle is at 53. Everything to the right of the circle is shaded.
A number line going from 50 to 58. An open circle is at 54. Everything to the right of the circle is shaded.
A number line going from 50 to 58. A closed circle is at 54. Everything to the right of the circle is shaded.
A number line going from 50 to 58. A closed circle is at 55. Everything to the right of the circle is shaded.
Given:
Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.
To find:
The graph that represents the set of heights that satisfy this requirement.
Solution:
Let x be the height required for the ride.
Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.
[tex]x\geq 54[/tex]
So, 54 and all values above 54 are in the solution set.
Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.
Therefore, the correct option is C.

If 6x − 8 = 26 , what is the value of 3x − 4 ?
Answer:
I'm pretty sure it's 32.
Step-by-step explanation:
8+6=14
26-14=12
x=12
If x is equivalent to 12 then your new equation is 3*12-4 which equals 32.
How would u solve this??
Answer:
n=1, m=3, and p=-4
Step-by-step explanation:
Take the fourth root of both sides
so x^n*y^m*z^p=x*y^3*z^-4;
notice z has a negative exponent because it was in the denominator
therefore, n=1, m=3, and p=-4

Look at the following numbers:
-7, 0, 7, 14
Which pair of numbers has a sum of 0?
Group of answer choices
0, 7
-7, 7
7, 14
-7, 14
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
Your answer is B.) -7, 7
Are the ratios 5:3 and 6:4 equivalent?
yes
no
Answer:
nope
Step-by-step explanation:
The given ratios 5:3 and 6:4 are not equivalent.
What are Equivalent ratios?Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.
Two or more ratios can be compared with each other to check whether they are equivalent or not.
The given two ratios are 5:3 and 6:4
We can write them as 5/3 and 6/4
Let us apply subtraction, if we get 0 then these are equivalent.
6/4-5/3
The LCM of 4 and 3 is 12

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2 + 34 = 10x
Answer:
So the intermediate step in question is (x - 10)² = 66
Step-by-step explanation:
Let's find out:
x² + 34 = 10x
x² - 10x = -34
x² - 20x + 100 = 66
(x - 10)² = 66
x - 10 = ± √66
x = 10 ± √66

Write an equation in slope-intercept form of the line that passes through (2,-2) and slope of -4
Answer:
y = - 4x + 6Step-by-step explanation:
Starting with the point-slope form of the equation {y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope}:
m = -4
(2, -2) ⇒ x₀ = 2, y₀ = -2
So, the point-slope form of the equation:
y + 2 = -4(x - 2)
Therefore:
y + 2 = - 4x + 8 {subtract 2 from both sides}
y = - 4x + 6 ← the slope-intercept form of the equation

Answer:
(3, - 2 )
Step-by-step explanation:
Given the 2 equations
4x - 2y = 16 → (1)
y = - 5x + 13 → (2)
Substitute y = - 5x + 13 into (1)
4x - 2(- 5x + 13) = 16 ← distribute and simplify left side
4x + 10x - 26 = 16
14x - 26 = 16 ( add 26 to both sides )
14x = 42 ( divide both sides by 14 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 5(3) + 13 = - 15 + 13 = - 2
solution is (3, - 2 )

A line passes through the point (–6, –3) and has a slope of 2/3 . Which point is on the same line?
Answer:
The point (0, 1) represents the y-intercept.
Hence, the y-intercept (0, 1) is on the same line.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven
The point (-6, -3)The slope m = 2/3Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = 2/3(x₁, y₁) = (-6, -3)substituting the values m = 2/3 and the point (-6, -3) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-3\right)=\frac{2}{3}\left(x-\left(-6\right)\right)[/tex]
[tex]y+3=\frac{2}{3}\left(x+6\right)[/tex]
Subtract 3 from both sides
[tex]y+3-3=\frac{2}{3}\left(x+6\right)-3[/tex]
[tex]y=\frac{2}{3}x+4-3[/tex]
[tex]y=\frac{2}{3}x+1[/tex]
comparing with the slope-intercept form y=mx+b
Here the slope = m = 2/3
Y-intercept b = 1
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
Given the line
[tex]y=\frac{2}{3}x+1[/tex]
at x = 0, y = 1
Thus, the point (0, 1) represents the y-intercept.
Hence, the y-intercept (0, 1) is on the same line.
Write the equation of a line in slope-intercept form that passes through (0, 7) and has a slope of -23.
Answer:
y = -23x + 7
Step-by-step explanation
We are using the equation y = mx + b.
The slope (m) is -23, so it would be y = -23 + b.
b is the y-intercept, and the ordered pair that gives us the y-intercept is (0,7).
Remember that the y-intercept is what the y-coordinate is equal to when the x-coordinate is 0.

What is the answer to this problem? Abby had $6.00 to spend on a treat with his 3 friends. If he spends the same amount on his 3 friends, what is his maximum amount of money he can spend on each person?
Answer:
$2.00
Step-by-step explanation:
Abby had $6.00 to spend on a treat with his 3 friends.
We are told in the question that: If he spends the same amount on his 3 friends
Hence: the maximum amount of money he can spend on each person is calculated as:
$6.00/3 friends
= $2.00
Therefore, the maximum amount of money that he can spend on each friend is $2.00
