3 0

Answer:

Step-by-step explanation:

4x + 11x - 3 = 0

15x = 3

x = 5

strojnjashka [21]

Answer:

A ≈ 158.37km²

<u>Using the formulas</u>

A=πr2

d=2r

<u>Solving forA</u>

A = 1 /4πd 2

= 1 /4·π·

14.22 ≈ 158.36769km²

Therefore, the are of the circle in nearest hundredth is A ≈ 158.37km²

You need to reverse the symbol to solve which inequality?
Marina86 [1]

When you multiply/divide by a negative number while solving the inequality, you reverse the symbol.

A.)  4(5 - y) ≥ 80       To solve this, isolate/get the variable "y" by itself in the inequality. Divide 4 on both sides

\frac{4(5-y)}{4} \geq \frac{80}{4}

5 - y ≥ 20       Subtract 5 on both sides

5 - 5 - y ≥ 20 - 5

-y ≥ 15     Divide -1 on both sides to get "y" by itself

\frac{-y}{-1} \geq \frac{15}{-1}       Because you are dividing by a negative number, you need to reverse the sign

y ≤ -15

B.) 2(y - 3) ≥ 8      Isolate "y", divide 2 on both sides

y - 3 ≥ 4      Add 3 on both sides to get "y" by itself

y ≥ 7

C.) 3y - 4 > 1       Add 4 on both sides

3y > 1       Divide 3 on both sides to get "y" by itself

y>\frac{1}{3}

D.) -\frac{3}{4} +6y > \frac{1}{4}       Isolate "y", add 3/4 on both sides

6y > 1     Divide 6 on both sides to get "y" by itseld

y>\frac{1}{6}
