How to tell if an ordered pair is a solution to a function

Mathematics
1 answer:
Evgen [1.6K]3 years ago
5 0
A) yes
B) yes
C) no

For each of these, substitute the value of x in the ordered pair into x in the function.

For A, x = -5; -5<2, so the piece of the function we want is f(x) = 3.  In our ordered pair, y=f(x)=3, so yes, it is a solution.

For B, x = 2; 2≤2<6, so the piece of the function we want is f(x) = -x+1.  In our ordered pair, y=f(x)=-1; -2+1=-1, so yes, it is a solution.

For C, x = 8; 8≥6, so the piece of the function we want is f(x) = x.  In our ordered pair, y=f(x)=-7; -7≠8, so no, it is not a solution.

The diameter of a grain of sand is estimated to be about .0024 inches. Write the estimated diameter of a grain of sand in scient
Orlov [11]

Answer:

2.4 x 10-₃

Step-by-step explanation:

the numbers with NO zeros should be first and the first number should be turned to a whole so like "2.4". Since there are 3 zeros (including the zero in the whole number place) you would write the 3 as the number in the right corner. And there is a minus sign beside the 3 because the Zeros are first. :)

What is the average rate of change for ƒ(x) = −2x + 70 over the interval 2 ≤ x ≤ 6?
Anvisha [2.4K]

Answer:

The average rate of change is -2

Step-by-step explanation:

we know that

To find out the average rate of change, we divide the change in the output value by the change in the input value.

In a linear function the average rate of change is a constant and is equal to the slope of the function

The linear function in slope intercept form is equal to

f(x)=mx+b

where

m is the slope or unit rate of the linear function

b is the y-intercept or initial value of the linear function

In this problem we have

f(x)=-2x+70

so

m=-2\\b=70

therefore

The average rate of change is -2

To mix weed killer with water correctly it is necessary to mix 6 teaspoons of weed killer with 2 gallons of water. Find how many
igomit [66]

The correct proportion for mixing weedkiller with water is;

6\text{tsp:}2\text{gal}

When the entire box contains 12 teaspoons of weedkiller, we would now have;

\begin{gathered} \frac{6}{2}=\frac{12}{x} \\ \text{Where;} \\ x=\text{gallons of water} \\ \text{Cross multiply and we'll have;} \\ x=\frac{12\times2}{6} \\ x=4 \end{gathered}

ANSWER:

To mix 12 teaspoons of weedkiller, 4 gallons of water is needed.

The area of the base of a rectangular juice box is 4 1/2 sq.in. If the volume of the box is 18 cubic inches, how tall is the box
Ksju [112]
Volume = Area x Height. We are given Volume and Area, so plug in and solve for Height (Height = Volume/Area)

18in^3 = 4.5 in^2 x Height (divide both sides by 4.5) -> 4in = Height
