Answer:
y = 10x - 46
Step-by-step explanation:
slope intercept form: y = mx + b
m is slope and b is y-intercept
given: y - 4 = 10(x-5)
1. distibute 10
y - 4 = 10x - 50
2. we need to get y by itself so bring -4 to other side
y = 10x - 50 + 4
y = 10x - 46
slope-intercept form is [tex]y=mx+b[/tex]
[tex]y=10(x-5)+4[/tex] ↣ We move -4 to another side and become positive number.
[tex]y=(10x-50)+4[/tex] ↣ Distribute 10 inside the brackets.
[tex]y=10x-50+4\\y=10x-46[/tex] ↣ Then we get the slope-intercept form.
Thus, the answer is [tex]y=10x-46[/tex]
A is the center of the circle, and the length of CD is 15 centimeters.
Name a segment that is a radius. How long is it?
AC: 7.5cm
CD: 7.5cm
CD: 15 cm
AC: 15cm
The radius of the circle will be 7.5 cm. Then the correct option is A.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
If the chord is passing through the origin. Then the chord will be the maximum chord and the maximum chord is known as the diameter of the circle.
A is the center of the circle, and the length of the CD is 15 centimeters.
The length CD is the diameter of the circle.
The length of the radius is calculated as,
AC = d / 2
AC = 15 / 2
AC = 7.5 cm
The radius of the circle will be 7.5 cm. Then the correct option is A.

Answer:
no, y does not vary directly with x
Step-by-step explanation:
If there is direct variation, the constant of variation can be found as ...
k = y/x
Here, those ratios are ...
y/x = 6/3 = 2
y/x = 18/6 = 3
y/x = 24/8 = 3
The ratio of y to x is NOT A CONSTANT, so there is no direct variation.

The coordinates of point T are (0,5). The midpoint of is (2,-5). Find the coordinates of point S.
The coordinates of point S is (4, -15)
How to find the coordinates of point S?The given parameters are
T = (0, 5)
Midpoint = (2, -5)
The midpoint of a line is calculated using
Midpoint = 1/2 * (x1 + x2, y1 + y2)
So, we have
(2, -5) = 1/2 * (0 + x, 5 + y)
This gives
(4, -10) = (x, 5 + y)
Solve for x and y
So, we have
x = 4
5 + y = -10
This gives
x = 4
y = -15
Hence, the coordinates of point S is (4, -15)

At the first store, the coach paid $110 for 5 footballs and 14 basketballs. At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs. What was the cost in dollars of each basketball?
Answer:
$6.25
Step-by-step explanation:
Each football costs the same amount, and each basketball costs the same amount.
Let the cost of:
Footballs = f
Basketballs = b
Hence, we have the following system of equations
At the first store, the coach paid $110 for 5 footballs and 14 basketballs.
5f + 14b = 110
At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs.
10f + 6b = 82.50
What was the cost in dollars of each basketball?
5f + 14b = 110..... Equation 1
10f + 6b = 82.50.....Equation 2
We solve using Elimination method.
Multiply Equation 1 by 10 and Equation 2 by 5 to eliminate f
50f + 140b = 1100.... Equation 3
50f +30b = 412.5.......Equation 4
Subtract Equation 4 from Equation 3
110b = 687.5
b= 687.5/110
b = $6.25
Therefore, the cost of one basketball in dollars = $6.25
4 thumb drives and 1 compact disk have a
total capacity of 18 gigabytes. 3 compact
disks and 4 thumb drives have a total
capacity of 22 gigabytes. Find the capacity
of 1 thumb drive (x) and the capacity of 1
compact disk (y).
The capacity of thumb drive disc is 4 gigabytes and the capacity of compact disc is 2 gigabytes.
How to calculate the equation?Let thumb drive = (x)
Let the capacity of 1 compact disk = (y).
Therefore, the appropriate equation will be:
4x + y = 18
4x + 3y = 22
Subtract the equations
2y = 4
y = 4/2
y = 2
The capacity of compact disc is 2 gigabytes.
Since 4x + y = 18
4x + 2 = 18
4x = 18 - 2
4x = 16
x = 16/4
x = 4
The capacity of thumb drive disc is 4 gigabytes.

Answer:
[tex]\displaystyle x=\frac{39}{10}[/tex]
What is the midpoint?The midpoint of a line bisects that line into two congruent line segments - otherwise speaking, they are equivalent to each other.
Due to this, we can set the equations equal and solve for x.
SolveFirst, set the equations equal to one another.

Subtract 7x from both sides of the equation to combine like terms.

At the restaurant, the cost of the meal before tax was $40. The tax is 8.5%, and Sheri wants to leave at least an 18% tip. Explain how to approximate the total cost of the meal.
Solution :-
given that,
→ Cost of meal before tax = $ 40
and,
→ Tax = 8.5%
So,
→ Total tax paid = 8.5% of cost of meal = (40 * 8.5)/100 = $ 3.4
now,
→ Tip = 18% of cost of meal = (18 * 40)/100 = $ 7.2
then,
→ Total cost of the meal = Cost of meal before tax + Total tax paid + Tip = 40 + 3.4 + 7.2 = $50.6 ≈ $51 (Ans.)
Shortcut :-
→ Total cost of the meal = Cost of meal * (100% + 8.5% tax + 18% tip) = 40(1 + 0.085 + 0.18) = 40 * 1.265 = $50.6 ≈ $51 (Ans.)
