Find the value of x.

Mathematics
1 answer:
Anna [14]4 years ago
6 0

Answer:

x = 5.

Step-by-step explanation:

ZY = 2*2x = 4x.   (Parallel line in a triangle theorem).

XZ = 2 * (4x + 1) = 8x + 2

XY = 2 *(2x + 3) = 4x + 6

So the perimeter 88 = 4x + 8x + 2 + 4x + 6

88 - 8 = 16x

16x = 80

x = 5.

(Sorry but I can't remember the exact name of the theorem).

F(x) = –2x2 + 4x and g(x) = x2 + 18x + 77.<br> What is (f•g)(x) in standard form?
Vikki [24]

Step-by-step explanation:

I take it this is meant to be a multiplication, right ?

not a "function of function", which would be symbolized by a little empty circle.

to multiply 2 function means basically the same as to add, subtract or divide 2 functions : to apply the arithmetic operation in both expressions.

(f×g)(x) = (-2x² + 4x)(x² + 18x + 77) =

= -2x⁴ - 36x³ - 154x² + 4x³ + 72x² + 308x =

= -2x⁴ - 32x³ - 82x² + 308x

Find the slope of the line that passes through the points (1, 3) and (5, -7).
lidiya [134]

The slope of any line is the fraction \frac{\Delta y}{\Delta x}, where \Delta y is the change in y-coordinate and \Delta x is the change in x-coordinate.

To find these changes, we take the <em>difference </em>of the corresponding x and y coordinate for the two points. Here, our y-coordinates are -7 and 3, and our x-coordinates are 5 and 1, so our slope is

\frac{-7-3}{5-1}=\frac{-10}{4}=\frac{-5}{2}
