Answer:
5y-2xy
6q-6
Step-by-step explanation:
For the first expression, we can multiply 5 by y to get 5y. Thats all we can simplify it though, because xy is not equal to x or y.
For the second equation, we can easily add the variables to simplify. 6q-6
Hope this helps!
The answer is 24. You subtract 40 - 16.
answer:
y = 2x - 5
work:
to write equations, we use the format y = mx + b.
m stands for the slope, and b stands for the y intercept.
this means that you should be able to enter the values for y and x and get a valid equation as a result.
in this equation, we are not given a y intercept value, but we do have a slope and x and y values, so we have to solve by substituting.
so, let's substitute in the values of y and x and the slope,
and solve for b, the y intercept.
1 = 2(3) + b (multiply 2 x 3)
1 = 6 + b (subtract 6 from both sides)
- 5 = b
b has a value of -5. let's place this into the equation.
y = 2x - 5.
the slope is 2, and the y intercept is -5, let's plug in our y and x values to verify that this is true.
1 = 2(3) - 5
1 = 6 - 5
1 = 1
so, this equation is correct. hope this helps and have a great day!
Answer:
y=3x-7
Step-by-step explanation:
we use the equation of the line:
y=mx+b
if the line is parallel, then the slope(m) of the line stays the same:
y=3x+b
we then substitute the ordered pair into the equation and solve for b:
-13 = 3(-2)+b
-13 = -6+b
-13+6 = b
-7 = b
now we substitute the b value into the original equation and the answer:
y=3x-7
Hope this helps :)
