Answer:
Step-by-step explanation:
we know that
The formula to calculate the coordinates of the midpoint between two points is equal to
we have that
The coordinates of hk
substitute in the formula to calculate the midpoint
Answer:
y = -4x + 2
Step-by-step explanation:
To figure out the slope, plug the coordinates in the formula.
y2 - y1 / x2 - x1
= 6 - (-6) / -1 -2
= -4
Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b
y = -4x + b
-6 = -4(2) +b
-6 = -8 + b
2 = b
In order to find the answer to this question, we need to use the quadratic formula.
-b +- √b² - 4ac
2a
In this equation, 5 is a, 16 is b, and -84 is c. You'll notice that the formula says 'plus or minus', meaning that there are two answers depending on whether you add or subtract. Let's start by adding.
-16 + √16² -(4(5)(-84)
2(5)
Use a calculator to simplify. Remember PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction) when deciding which order to go in.
-16 + 44
10
2.8
One solution is 2.8. Now, let's do the same thing, but subtract this time. Keep in mind that the number under the radical stays the same, so you don't have to recalculate that.
-16 - 44
10
-6
The solutions to the equation are 2.8 and -6.
Hope this helps!
Answer:
The factors are 9, y, 2, 2, y and 2.
Step-by-step explanation:
when you combine a number with another number, then that means you need to multiply. The 2 numbers that are multiplied are the factors.
