Answer:
24
Step-by-step explanation:
8 x 6 = 48 and 48/2 = 24
(Y1-Y2)/(X1-X2)
(2-4)/(-2-3)
-2/-5
2/5
Answer:
-3
Step-by-step explanation:
The line passes through (1,0) and (0,3)
Slope = Change in y ÷ change in x
Slope =
= -3
Use subtitution method to solve the problem.
First, change y to the value of x in order to find the exact value of x.
x + y = 4
y = 4 - x
Second, subtitute y with 4 - x from the first equation
y = -x² + 2x + 4
4 - x = -x² + 2x + 4
move all terms to the left side
x² - 2x - x + 4 - 4 = 0
x² - 3x = 0
x(x - 3) = 0
x = 0 or x = 3
Third, now we have 2 values of x. Find the value of y for each of x
For x = 0
y = 4 - x
y = 4 - 0
y = 4
For x = 3
y = 4 - x
y = 4 - 3
y = 1
The solution is (0,4) and (3,1). The answer is option b
Step-by-step explanation:
this problem seeks to test our knowledge on word problems and algebra
<u>Solution</u>
let the base be x, and
the height h = 2x+4
We know that area of a triangle is given as

substituting our given values we have

re-arranging we have

we can now find two factors that will add up to give 2 and multiply to give -168
they are 14 and -12
The possible base of the triangle is 14 in
and the height is
