Identify the equation of the line graphed (I need help can someone explain)
Answer:
D.) 5x - 2y = 2
Step-by-step explanation:
1. Find all of the options and convert them to slope-intercept form by isolating y. If you isolate y on all of them, you should get that A is y =-2/5x - 1, B is y = 2/5x - 1, C is y = -5/2x - 1, and D is y = 5/2x - 1.
2. Use logic. This line cannot be negative, because negative lines go up to down, not down to up. That cancels out the possibility of A.) and C.) being answers. Now, we know that the slope has to be more than 1 because it is more compressed than that of a line with a slope of 1. The only slope that is more than 1 is D, so that makes D the answer (If you didn't understand this step, go to step 3).
3. Find the slope (This step does not need to be done if you understood Step 2). Take 2 points to be able to find the slope. Two random points on this line are (2,4) and (0,-1). Next, plug them into the formula to find slope. 4-(-1)/2-0 = 5/2, so the slope is 5/2. The only equation with a slope of 5/2 is D. D is the answer.
Answer: D.) 5x - 2y = 2

Step-by-step explanation:
If 2 (3t - 10) + t = 40 + 4t, what is the value of 3t?
Answer:
3t = 60
Step-by-step explanation:
2(3t - 10) = 40 + 3t
6t - 20 = 40 + 3t
3t - 20 = 40
3t = 60
If you need to simplify that then the answer would be t = 20.

A driver is 15 feet below the surface of the water 10 seconds after he entered the water and 90 feet below the surface after 40 seconds. What is the rate of change?
Answer:
[tex]\frac{-75ft}{30sec}[/tex] or simplified would be [tex]\frac{-2.5ft}{sec}[/tex]
Step-by-step explanation:
In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...
[tex]\frac{-90ft - (-15ft)}{40sec - 10sec} =[/tex] rate of change
[tex]\frac{-75ft}{30sec} =[/tex] rate of change
[tex]\frac{-2.5ft}{sec}[/tex] = rate of change
Therefore, we can see that the rate of change of the diver is [tex]\frac{-75ft}{30sec}[/tex] or simplified would be [tex]\frac{-2.5ft}{sec}[/tex]

How does anyone know how to prove parallel lines, especially when there are two pairs of them?
Answer:
Step-by-step explanation:
If two lines are cut by a transversal so that any pair of alternate interior angles are congruent, then the lines are parallel. If two lines are cut by a transversal so that any pair of corresponding angles are congruent, then the lines are parallel. You can use these converses to decide whether two lines are parallel.
At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions. If x represents the number of hand soaps and y represents the number of lotions she bought, which inequality best represents her purchase?
x + y 12
x + y ≤ 12
x + y ≥ 12
Answer:
the answer is b
Step-by-step explanation:
edge 2021
The inequality which best represents the purchase is x + y > 12.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions.
Let x represents the number of hand soaps she bought.
Let y represents the number of lotions she bought.
x + y is more than 12.
So the inequality is,
x + y > 12
Hence the correct inequality is x + y > 12.

What is the length of the radius of a circle with center (10, -14) that is tangent to the line
x=13?
Answer:
length of radius of a circle = 3
Step-by-step explanation:
a tangent line touches the circle at one point
if the tangent line is at x=13 (vertical line) and the center of the circle is
(x,y) = (10,-14) with its center x at 10; then take the difference to find the radius;
x(tangent line) - x(center of circle) = radius of circle
length of radius of a circle = 13-10 = 3
you can also graph the circle and draw the tangent line to find the radius
The length of the radius of a circle as described in the question is; 14.32
The center of the circle is at; (10, -14)
The line that is tangent to the circle is; x = 13.
The coordinate of a point on the line is therefore; (13, 0)
The length of the radius of the circle can.be obtained from Pythagoras theorem as;
(Radius)² = (13-10)² + (-14-0)²(Radius)² = (3)² + (-14)²(Radius)² = 9 + 196Radius = √205Radius = 14.32Read more:

Your bike has a wheel diameter of 29 inches. You are traveling and your wheels are rotating at 148 revolutions per minute. What is the bicycle speed in miles per hour. (Round your answer to the nearest 1000th)
Answer:
12.77 miles per hour
Step-by-step explanation:
Step 1
Convert the diameter from inches to feet
Your bike has a wheel diameter of 29 inches.
1 inch = 0.0833 feet
29 inches =
29 × 0.0833 feet
= 2.41667 feet
Step 2
Circumference of the tire = πD
= π × 2.41667 feet
= 7.5921927182 feet
Step 3
The number feet traveled per hour is
148 revolutions per minute × 7.5921927182 feet
= 1123.6445223 feet per minute
60 minutes = 1 hour
Hence,
1123.6445223 × 60 =
67418.671337 feet per hour.
Converting from Feet per hour to Miles per hours
1 mile = 5280 feet
= 67418.671337 feet per hour/5280 feet
= 12.768687753 miles per hour
Approximately = 12.769 miles per hour

Step-by-step explanation:
Aubrey and Charlie are driving to a city that is 120 miles from their house. They have already traveled 20 miles, and they are driving at a constant rate of 50 mi/h. Part A Write the function that models their distance from home as a function of time. f(x) = x + Part B What is a reasonable domain for this situation? ≤ x ≤
their distance from home as a function of time
[tex]f(x)=50x+20[/tex]
The reasonable domain for this situation is
[tex]0\leq x\leq 2[/tex]
Given :
Aubrey and Charlie are driving to a city that is 120 miles from their house. They have already traveled 20 miles, and they are driving at a constant rate of 50 mi/h.
Given driving speed is 50 miles per hour
They already travelled 20 miles. We need to frame linear equation because we are given with constant rate.
Linear equation is [tex]f(x)=mx+b[/tex]
where m is the constant rate and b is the initial miles travelled
m=50 and b=20
the function f(x) is the distance from home
[tex]f(x)= 50x+20[/tex]
Now we find out the domain x. Given that they travelled 120 miles
so f(x) is 120
[tex]120=50x+20\\120-20=50x\\100=5x\\x=2[/tex]
Domain is the number of hours travelled
hours cannot be negative . So the domain x for this situation is
[tex]0\leq x\leq 2[/tex]
