y = 3x-2x∧2+5x∧3

When we replace x with value 3 we get

y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126

good luck!!!

Math help? 15 Points

Masja [62]

I think the best answer would be F.
When √10 is converted into a decimal it is 3.16, and F is the most close to that.
Hope this helps!

A circle has a diameter with endpoints of (-3, 8) and (7, 4). What is the center of the circle?

Alexeev081 [22]

The center of the circle is expressed as (h,k) in the standard form of equation. In this case, the diameter endpoints are <span>(-3, 8) and (7, 4). Hence the circle center has coordinates which are the midpoints of the two points.

x = (-3 + 7) /2 = 2
y = (8 + 4) /2 = 6

hence the center of the circle is (2,6)</span>

Write an inequality that represents the fact that while making your product

Helga [31]

Answer:

$x \leq 40 / 0.25\\ x \leq 160\\$

Step-by-step explanation:

If the spending limit is $ 40 and making each beads costs $ 0.25, then the amount of accounts you must do multiplied by the manufacturing cost should not exceed $ 40.

Then the inequation that this restriction would represent is:

$0.25x\leq 40\\$

Where x is the number of beads made.

This could also be written more specifically:

$x \leq 40 / 0.25\\ x \leq 160\\$

Therefore the number of beads must be less than or equal to 160
