Step-by-step explanation:
Im not sure if its supposed y = -2x + 1 or y = 2x + 1 but I'll solve the problem for both.
First for y = -2x + 1
Since the line has to be parallel to y = -2x + 1
the slopes would be the same.
so, so far the equation would be
y = -2x + b
now we substitute (5,2) into the equation
2 = -2(5) + b
2 = -10 + b (Add 10 to both sides of the equation)
+10 +10
12 = b
Now that we solved for b
The equation would be
y = -2x + 12
^^ This equation is parallel to y = -2x + 1
Now to solve for an equation parallel to y = 2x + 1
Both equations would have the same slope
So far we would have
y = 2x + b
Now we solve for be by substituting the point (5,2)
2 = 2(5) + b
2 = 10 + b (subtract 10 from both sides)
-10 -10
-8 = b
After solving for b
The equation is
y = 2x - 8
This equation is parallel to y = 2x + 1
Answer:
Step-by-step explanation:
The construction of the figure gives us three right triangles, where we can apply Pythagora's Theorem.
I have added two variables to the image in the picture attached.
On the triangle with sides y,h,16 we have:
On the triangle with sides h,z,25 we have:
Equating :
On the bigger triangle with sides y,z,16+25=41 we have:
Adding this last equation with [1]:
Simplifying:
Operating:
Dividing by 2:
Taking square root:
y=20
To enter the number in the required format:
This problem would just be x + (x +7) = 25. It can be simplified to 2x = 18, which can be further simplified to x = 9. 9 is one of your answers. To find the other number, just add 7. Your numbers would be 9 and 16, which do add to 25.
Answer:
8x = 16 x=2
Step-by-step explanation:
You get 75% which is .75, then you get 4/5 which is .80, and then .90
