what is the value of y?
A. 56°
B. 68°
C. 44°
D. 112°
Answer:
The answer is option BStep-by-step explanation:
Since the figure above is a triangle all it's interior angles sum up to 180°.
To find y add up all the angles and equate them to 180 and solve for y
That's
y + y - 12 + 56 = 180
2y + 44 = 180
2y = 180 - 44
2y = 136
Divide both sides by 2
We have the final answer as
y = 68°Hope this helps you
Which equation represents the data in the table shown?
A) y = -2x
B) y = 2x + 3
C) y = -2x + 3
D) y = -2x - 3
Answer:
C
Step-by-step explanation:
In order to find the slope, you can use rise over run.
(y₂ - y₁) over (x₂ - x₁)
You can use the points (1, 1) and (2, -1). y₂ can be -1 and y₁ can be 1, but you could do either as long as you make x₁ and x₂ from the corresponding points (so y₁ and x₁ are one coordinate pair and y₂ and x₂ are the other). This way, you get -2 as your slope. Then, the table shows that y = 3 when x is 0, so that's your y-intercept, which is how you get +3. Hope this helps!
y = -2x + 3 will be the equation represents the data in the table shown.
What is Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given, A data Set of the value of x and y that represents a linear equation.
From the slope intercept form of a linear equation,
y = mx + b,
where m is the slope
b is the y-intercept
y- intercept is point in line where the value of x will be 0.
From our data set,
y - intercept = b = 3 (since, at x = 0, y is 3)
And Slope, (m) = (y₂ - y₁)/(x₂ - x₁)
in our case,
m = (1-3)/(1-0)(from first two values of data set)
m = -2
Thus,
Equation of line:
y = -2x + 3
Therefore, The equation of line for the given data set will be y = -2x + 3.

You are in a bike race. When you get to the first checkpoint, you are 25 of the distance to the second checkpoint. When you get to the second checkpoint, you are 14 of the distance to the finish. What is the distance from the start to the first checkpoint?
Question:
You are in a bike race. When you get to the first checkpoint, you are 2/5 of the distance to the second checkpoint. When you get to the second check point, you are 1/4 of the distance to the finish. If the entire race is 40 miles, what is the distance between the start and the first check point?
Answer: 4 miles
Step-by-step explanation:
Let distance between start to first checkpoint = x
First checkpoint to second checkpoint = 2/5 of x
Distance of start to checkpoint 1 = ( 2/5 of start to checkpoint 2)
Distance of start to checkpoint 2 = (1/4 of start to finish)
If start to checkpoint 2 = 1/4 of start to finish
Then,
Distance of start to checkpoint 1 = ( 2/5 * 1/4 of start to finish)
Distance of start to checkpoint 1 = 2/20 of start to finish = 1/10 of start to finish
Entire race = 40 miles = distance from start to finish
1/ 10 of 40
= ( 1/10) × 40
= 4 miles

5. Two trains start from the same station and run in
opposite directions. One runs at an average rate of 40
miles per hour, and the other at 65 miles per hour. In
how many hours will they be 315 miles apart?
Answer:
3 hours
Step-by-step explanation:
40 + 65 = 105
315/105 = 3
The number of hours for both the trains to be at 315 miles apart is 3 hours
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first train be = A
Let the second train be = B
The average speed of train A = 40 miles per hour
The average speed of train B = 65 miles per hour
Since , the two trains are moving in opposite directions , their speed are added
The total average speed of train A and train B =
( average speed of train A + average speed of train B )
The total average speed of train A and train B = 40 + 65
= 105 miles per hour
Total distance = 315 miles
The equation is
So , the time taken for the two trains to be at 315 miles apart is
Time = Distance / Speed
= 315 / 105
= 3 hours
Hence ,
The number of hours for both the trains to be at 315 miles apart is 3 hours

7x + 15 = 2(3x + 8) + X
Answer:There are no solutions
Step-by-step explanation:
Answer:
No solution (or false)
Step-by-step explanation:
First, use the distributive property.
7x + 15 = 6x + 16 + x
Next, combine like terms.
7x + 15 = 7x + 16
Now, get both of the coefficients to the same side by subtracting 7x from both sides.
15 = 16
15 does not equal 16, so the answer to this problem would be no solution

Step-by-step explanation:
when surviving you need basics. first, food. you can last 20-30 days without food but you always need it because lasting at least 5 days will make your stomach feel very bad. Now water, you can last 3-6 days without water or some sort of fluid. So this is a priority.
