Answers

Answer 1

Answer:

f(2) = - 1

Step-by-step explanation:

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing
through the point (5,9). Is either of them correct? Explain your reasoning?
Krista:
9 = 3(5) + b
9 = 15 + b
-6 = b
y = 3x - 6
Emily:
y- 9 = 3(x - 5)
y- 9 = 3x - 15
y = 3x - 24
Answer:
Explanation:

Answers

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

[tex](y - y1) = m1(y - y1)[/tex]

Put the values,

[tex](y - 9) = m1(x - 5)[/tex]

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

(6a - 10) = 12 – (6 - 3a), when b=11
A = ?

Answers

Answer:

a = 5.333..  or 5 1/3

Step-by-step explanation:

I am not sure what your question is but it looks like you need to solve for  a.

Based on that fact:

6a - 10 = 12 - 6 +  3a      you multiply -1  by each term in the parenthesis

Then it is simple algebra

6a -10          =        6+ 3a

     +10               + 10                   add 10 to both sides

6a                =  16  + 3a

-3a                         -3a                 add  -3a to both sides

3a  = 16                     Divide both sides by 3

a = 5.3333

The length of an alligator in a zoo is 14 5/6 feet.The everglades national parks list the longest alligator ever reocord in florida at 17 5/12 feet. Which is the differnce in their lenghth

Answers

Answer:

The difference in the lengths of the two alligators = 3

Step-by-step explanation:

First, let us make the lengths improper fractions, then we will find the difference from there.

Alligator 1:

Length = [tex]14\frac{5}{12} = \frac{173}{12}[/tex]

To convert to improper fraction, multiply the denominator by the whole number, and then add the denominator [(12 × 14) + 5]

Alligator 2:

Length = [tex]17\frac{5}{12} = \frac{209}{12}[/tex]

Now Let us find the difference between the lengths:

[tex]\frac{209}{12} - \frac{173}{12} = \frac{36}{12} =3[/tex]

Therefore the difference in the lengths of the two alligators = 3

The circumference of a quarter is approximately 7.54 mm. What is its diameter to the nearest tenth of a millimeter? (π = 3.14)

Answers

Answer:

2.40mm

Step-by-step explanation:

In this problem. we are required to solve for the diameter of a circle.

Given data

circumference of circle c= 7.54mm

we know that the expression for the circumference is given as

c= 2πr

We can substitute our given data to solve for r

7.54= 2*3.142*r

7.54=6.284*r

divide both sides by 6.284 we have

r= 7.54/6.284

r= 1.199

diameter = 2*r

diameter= 1.199*2

diameter= 2.399

to  the nearest tenth

diameter= 2.40mm

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5

Answers

Answer:

3

Step-by-step explanation:

So we have the function:

[tex]f(x)=3x^2+2x-5[/tex]

To evaluate the value of f(-2), substitute -2 for x. Thus:

[tex]f(-2)=3(-2)^2+2(-2)-5[/tex]

Square first:

[tex]f(-2)=3(4)+2(-2)-5[/tex]

Multiply:

[tex]f(-2)=12-4-5[/tex]

Now, subtract:

[tex]f(-2)=8-5=3[/tex]

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells x x shirts can be found using the function f ( x ) = 8 x − 40. F(x)=8x−40. Find and interpret the given function values and determine an appropriate domain for the function.

Answers

Answer:

Domain = [0, ∞).

Step-by-step explanation:

he profit, in dollars, when the company sells x shirts can be found using the function

[tex]f(x)=8x-40[/tex]

For x=0,

[tex]f(0)=8(0)-40=-40[/tex]

It means, if company sells 0 shirts, then company makes loss (because of negative sign) of $40.

For x=5,

[tex]f(5)=8(5)-40=0[/tex]

It means, if company sells 5 shirts, then company makes profit of $0 means no loss no profit.

For x=10,

[tex]f(10)=8(10)-40=40[/tex]

It means, if company sells 10 shirts, then company makes profit of $40.

Domain is the set of input values.

We know that number of shirts can not be negative, therefore the value of x is always greater than or equal to 0.

Domain = [0, ∞).

Therefore, the domain for the function is [0, ∞).
