Slope-intercept form: y=mx+b, with m being the slope and b being the y-intercept. First, plug in the given slope into the slope form:
y=2x+b
Now, given the coordinates (1,4), you can plug the coordinates into the equation for x and y respectively, to solve for b (the y-intercept).
4=2(1)+b
4=2+b
Subtract 2 from both sides.
2=b
The y-intercept is 2.
Now, plug that into the equation:
y=2x+2
The answer is y=2x+2.
I hope this helps :)
Answer:
11
Step-by-step explanation:
|11| is a module, the numbers inside a module are equal to positive ones so
|11| and |-11| are both equal to 11
<h2>(25) 7th Grade Swimmers</h2><h2>25:80</h2>
The combined payment is 743.75.
The annual amount of insurance is 1560. Dividing this by 12 gives us the monthly amount paid:
1560/12 = 130.
The annual real estate taxes are 1890. Dividing this by 12 gives us the monthly amount paid:
1890/12 = 157.50
We add these to the monthly mortgage payment to find the total amount:
456.25+130+157.50 = 743.75
Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
