The product of -1.24 and 4.25 is -5.27
To find the slope use the formula
Y2-Y1
---------
X2-X1
(-1,-4) (1,4)
4- -4 = 8
-------------
1- -1 = 2
8/2=4 This will be your slope
Y=4x
Now we must figure out the y-intercept using the formula
Y-y1=slope(x-x1)
Y- -4= 4(x- -1)
Y+4= 4x + 4 The 4 distributes to the x and -1
Y=4x +4
-4
Y= 4x
This is your answer in slope intercept form.
P.S if you have a number minus a negative number it makes it a positive number
Answer:
10a^2b^2
Step-by-step explanation:
Formula = 1/2(b)(h)
h = 4a
b = 5ab^2
4a(5ab^2) = 20a^2b^2/2 = 10a^2b^2
The perimeter of any shape is a measure of the length of the peripheral of that shape.
For a triangle, it is an addition of the length of the 3 sides.
P = a + b + c where a, b, c are the lengths of the individual sides.
p = 10x + 5y = (3x + 4y) + (5x - y) + c
Collecting like terms on the RHS, we have
p = 10x + 5y = 8x + 3y + c
Subtracting 8x + 3y from both sides to give c leaves us with
10x + 5y - (8x + 3y) = c
c = 10x - 8x + 5y - 3y
c = 2x + 2y
Answer: 38.185 ft
Hypotenuse side of triangle: 8.25
Length of two sides of rectangle: 18
Circumference of half circle= 2(pi)(r) = 2(3.14)(4)= 25.13
25.13/2= 12.565
8.25+18+12.565=38.185 ft
