Answer:

The x and y values of the coordinates satisfy the system of equations.

Step-by-step explanation:

HIJK is a rectangle. Find the value of x and find the length of each diagonals. If hj=19+2x and ik=3x+22
viva [34]
Hj  and ik are  opposite sides of the rectangle so they areequal in length.

19 + 2x = 3x + 22
19-22 = 3x-2x
x = -3 

We can't find the length of the diagonals as we have no information about the width.

Consider the function f(x) = 4x² - x + 3. What is f(1)?
zhannawk [14.2K]

Replace every x you see in the function with 1 and simplify.

Let x be 1.

f(1) = 4(1)^2 -(1) + 3

f(1) = 4(1) - 1 + 3

f(1) = 4 - 1 + 3

f(1) = 3 + 3

f(1) = 6

Done!
