Answer:

\boxed {f < 4}

Step-by-step explanation:

Solve the following inequality:

3f + 9 < 21

-Subtract 9 on both sides:

3f + 9 - 9 < 21 - 9

3f < 12

-Divide both sides by 3:

\frac{3f}{3} < \frac{12}{3}

\boxed {f < 4}

Tonya is making a scale model of a monument that is 160 feet tall. If she uses a scale of 4 in. = 5 ft., how tall should she mak
olasank [31]

Answer:

<u>It should be 128 inches or 10.67 feet tall</u>

Step-by-step explanation:

Real size of the monument = 160 feet tall

Scale used by Tonya = 4 inches equal to 5 feet

Scale model of the monument = Real size of the monument / Scale used

Proportion between real monument and scale model = 160 / 5 = 32

It means that the proportion between the real monument and the scale model is 32

Scale model height = Proportion * scale used

Scale model height = 32 * 4

<u>Scale model height = 128 inches</u>

<u>Scale model height = 128/12 = 10.67 feet (12 inches = 1 feet)</u>

Mark all the statements that are true.
Artyom0805 [142]

Answer:

Option A

Option C

Step-by-step explanation:

A relationship is defined as a function if and only if each element of the "domain" set is assigned only one element of the "range" set. That is, there is only one output value y assigned to each input value x.

The relation x = 3 is not a function because there are infinite output values y, assigned to the same input element x.

(3, 2), (3, 5) (3, 9) (3,10000)

<u><em>Then the option A is true</em></u>

<em><u>Option C is also true,</u></em> the equation of the line shown is

x = 3

The rest of the options are false because x = 3 is not a function
