Step-by-step explanation:
When a number is tripled, its value increases by 10. What is the original value?
[tex]3x=x+10[/tex]
We tripple something and get 10 more than something.
Put the x-es on the left and non x-es to the right,
[tex]2x=10[/tex]
Divide both sides by 2,
[tex]x=5[/tex]
Et Viòla.
Hope this helps :)
When a number is tripled, its value increases by 10 then the original number is 5.
Let's call the original number "x". According to the problem, when this number is tripled, its value increases by 10. Mathematically, we can represent this as an equation:
3x = x + 10
Now, we can solve for "x" step by step:
1. Subtract "x" from both sides of the equation:
3x - x = 10
2. Simplify the left side:
2x = 10
3. Divide both sides by 2 to solve for "x":
x = 10 / 2
x = 5
So, the original number "x" is 5.
In other words, if you take a number, triple it (multiply by 3), and then increase the result by 10, you would end up with the value 5. This can be verified by checking:
3 * 5 = 15
15 + 10 = 25
The equation 3x = x + 10 represents the relationship between the original number and its tripled value with an increase of 10. Solving this equation helps us find the original value that satisfies the given condition.

A line passes through the point (2, 3) and has a slope of -8. Write an equation for this line.
Answer:
y = -8x+19
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -8x+b
Substitute the point into the equation
3 = -8(2)+b
3 = -16+b
Add 16 to each side
3+16 = b
19 = b
y = -8x+19
Step-by-step explanation:
to find the equation of this line you use the equation of the slope intercept which is y-y1= m (x-x1)
y-3=-8(x-2)
y-3=-8x+16
y=-8x+16+3
y=-8x+19

Step-by-step explanation:
Where AB and CD are parallel lines:
the y-intercept of line AB is -56/5
the equation of line CD is: y = 7/5x - 2
What is the Slope of Parallel Lines?If two lines are parallel, they will have the same slope (m) value in their equation, y = mx + b (slope-intercept form).
Find the slope of AB:
Slope of AB (m) = change in y / change in x = (7 - 0)/(3 - 8) = 7/5
To find the y-intercept (b) of AB, substitute (x, y) = (8, 0) and m = 7/5 into y = mx + b
0 = 7/5(8) + b
0 - 56/5 = b
b = -56/5 (y-intercept of AB)
AB is parallel to CD, so, CD will have the same slope of 7/5.
To find the equation of CD, substitute m = 7/5 and (a, b) = (5, 5) into y - b = m(x - a)
y - 5 = 7/5(x - 5)
y - 5 = 7/5x - 7
y = 7/5x - 7 + 5
y = 7/5x - 2 (equation of line CD)

Let the set A be defined as follows.
A={h,m,s,d,c}
(a) Find the total number of proper subsets of A.
(b) Find the total number of subsets of A.
Answer:
(a) 31
(b) 32
Step-by-step explanation:
We will do (b) first since it will help us do (a).
(b)
There are [tex]n(A)=5[/tex] elements in [tex]A[/tex]. Using the formula for the number of subsets of a given (finite) set, the number of subsets of [tex]A[/tex] is
[tex]2^{n(A)}=2^5=32[/tex]
(a)
A subset of [tex]A[/tex] is called proper if it does not equal [tex]A[/tex]. The only subset of [tex]A[/tex] that is not proper is [tex]A[/tex] itself, so simply subtract 1 from the number of subsets to get the number of proper subsets, which is

Damon can flip 5 pancakes in 20 seconds,
working at a constant rate. Hailey can flip
2 pancakes in 10 seconds, working at her
own constant rate. What is the total number
of pancakes the two of them can flip in 2
minutes?
Answer:
24 + 30 = 54 pancakes flipped in 2 minutes :)
Step-by-step explanation:
damon = 5 pancakes in 20 seconds
we do 20 x 3 and 5 x 3 to find how many pancakes he can flip in a minute
15 pancakes and a minute, we then multiply them by 2 to get the amount for 2 minutes
30 pancakes flipped in 2 minutes
Hailey = 2 pancakes in 10 seconds. to make it an equal amount of pancakes per second with damon, i will multiply them by 2 to have 4 pancakes in 20 seconds
we will then do 4 x 3 and 20 x 3 to find out how many pancakes per minute
then we multiply by 2 for 2 minutes
Answer:
54
Step-by-step explanation:
2 minutes=120 seconds
Damon=120 divide 20=6
6x5=30
Hailey=120 divide 10=12
12x2=24
24+30=54

Parallel means that two lines are lined up in the same directions and will never intersect even if they were extended forever in directions.
Let's look at the first option of AB, and AD. We can see that both lines intersect at point A, so AB and AD are not parallel.
For the next option of CD and BE, we can see that both lines don't intersect and won't ever even if the lines were extended. So, CD and BE are parallel.
For the third option, we have BC and DE. These lines don't intersect and aren't in line to ever do so. Therefore, BC and DE and parallel.
The last option is AD and BC. These two lines will never meet, but, they aren't line up in the same directions. AD is traveling upwards while BC isn't. Think about being able to make a road out of the two lines, it would never work. AD and BC are not parallel.
To sum it up: You should select the 2nd and 3rd options because those lines are parallel.

e.) $24
The cost of one barrel of gasoline given the total amount made from all the barrels sold is $20.
What is the cost of one barrel of gasoline ?A pie chart is a graph that displays information using a circle. The circle is divided into sections which represent a numerical proportion. The sum of percentages in a pie chart is 100%.
The first step is to determine the number of barrel of gasoline.
Number of barrels of gasoline = percentage of gasoline x number of barrels
34% x 60 million
0.34 x 60 million = 20.4 barrels
The second step is to divide the total amount generated from the sales by the number of barrels.
Cost of one barrel of gasoline = 408 million / 20.4 million = $20

Which of the following graphs shows a parabola with a vertex of (1,-9) and solutions of (-2,0) and (4,0)?
Answer:
Hello,
Step-by-step explanation:
Roots are -2 and 4
y=k*(x+2)(x-4)
Vertex = (1,-9) is a point of the parabola
-9=k*(1+2)(1-4) ==> k=1
Equation of the parabola is y=(x+2)(x-4)
But you don' t have given the graphs !!!!
The graph show a parabola with a vertex that has Roots are -2 and 4.
What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
Given that,
The vertex of (1,-9) and solutions of (-2,0) and (4,0).
y = k*(x+2)(x-4)
Vertex = (1,-9) is a point of the parabola
-9 = k*(1+2)(1-4)
Substitute the value of k = 1 in the equation,
The equation of the parabola is y = (x+2)(x-4).

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of
$750. What was the rate charged per hour by each mechanic if the sum of the two rates was $105 per hour?
Step-by-step explanation:
let's convert the statement into equation..
let the charge of 1st mechanic be x and second be y..
by the question..
10x+5y=750...(i)
x+y=105..(ii)
from eqn(ii)..
x+y=105
or, x=105-y...(iii)
substituting the value of x in eqn (i)..
10x+5y=750
or, 10(105-y)+5y=750
or, 1050-10y+5y=750
or, 1050-750=5y
or, y=300/5
•°• y=60
substituting the value of y in eqn(iii).
x=105-y
or, x=105-60
•°• x= 45..
the rate charged by two mechanics per hour was 60$ and 45$

5 = 20e ^2t
in 5 = 2t
Therefore t = in5/ 2
Step 1 was ; Divide by the coefficient of the power

Step 3 was; Divide by the coefficient of t
Another example;

Solution
Analysis
When we plan to use factoring to solve a problem, we always get zero on one side of the equation, because zero has the unique property that when a product is zero, one or both of the factors must be zero. We reject the equation e^x=−7 because a positive number never equals a negative number. The solution ln(−7) is not a real number, and in the real number system this solution is rejected as an extraneous solution.
Another example is;
Solve e^2x=e^x+2 .
Answer
Q&A: Does every logarithmic equation have a solution?
No. Keep in mind that we can only apply the logarithm to a positive number. Always check for extraneous solutions.
