You need to reverse the symbol to solve which inequality?

Mathematics

Marina86 [1]2 years ago

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}

Please help<br><br> I need help creating a table of value for this equation
Fed [463]

Answer:

Create the table and choose a set of x values. Substitute each x value (left side column) into the equation. Evaluate the equation (middle column) to arrive at the y value. An Optional step, if you want, you can omit the middle column from your table, since the table of values is really just the x and y pairs.

Step-by-step explanation:

Specify a name for the function.

Specify a name and data type for each input parameter.

Specify the routine attributes.

Specify the RETURNS TABLE keyword.

Specify the BEGIN ATOMIC keyword to introduce the function-body.

Specify the function body.

L=x²*y in
W=x in
H=y² in

[volume of the prism]=(x²*y)*(x)*(y²)-----> x³*y³ in³

the answer is
