Answer:
You can use the midpoint formula.
Method:
MAB = (Ax+Bx)/2 ; (Ay+By)/2
Substitute in what you have:
(2;4) = (Ax+3)/2 ; (Ay+7)/2
Because we know the x coordinate of the midpoint, we can assume that:
2 = (Ax+3)/2
And now solve for Ax:
4 = Ax+3
Ax = 1
Because we know the y coordinate of the midpoint, we can assume that:
4 = (Ay+7)/2
And now solve for Ay:
8 = Ay+7
Ay = 1
Therefore A(1;1)
Answer:
Step-by-step explanation:
58% of 10 pounds = 0.58 × 10 pounds = 5.8 pounds
96.2857143 would be the answer because you add all the numbers together then divided by 7
I looked it up, and after some research, I came across a legitimate answer of approximately 30 gallons.
Answer:
The solution for the system of equations is
x=2,y=−2
Explanation:
4x−3y=14.....equation (1)
y=−3x+4.....equation (2)
Solving by substitution
Substituting equation 2 in equation 1
4x−3⋅(−3x+4)=14
4x+9x−12=14
13x=14+12
13x=26
x=2
Finding y by substituting x in equation 1
4x−3y=14
4⋅2−3y=14
8−3y=14
8−14=3y
3y=−6
y=−2
