The regression equation y = 8.6sin(0.24x – 1.88) + 62.8 models the Fahrenheit temperature in a room x hours after midnight. What is the maximum temperature in the room during the first 24 hours?

Given:

Jayla says that the equation [tex]y=2x-3[/tex] matched the graph.

To prove:

Jayla is correct

Solution:

We have,

[tex]y=2x-3[/tex]      ...(i)

The ordered pairs are (3,3), (4,5), (5,7).

We need to substitute the ordered pairs into the equation to prove that Jayla is correct.

For point (3,3), put x=3 and y=3 in (i).

[tex]3=2(3)-3[/tex]

[tex]3=6-3[/tex]

[tex]3=3[/tex]

[tex]LHS=RHS[/tex]

So, point (3,3) lies on the line [tex]y=2x-3[/tex].

For point (4,5), put x=4 and y=5 in (i).

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

[tex]5=8-3[/tex]

[tex]5=5[/tex]

[tex]LHS=RHS[/tex]

So, point (4,5) lies on the line [tex]y=2x-3[/tex].

For point (5,7), put x=5 and y=7 in (i).

[tex]7=2(5)-3[/tex]

[tex]7=10-3[/tex]

[tex]7=7[/tex]

[tex]LHS=RHS[/tex]

So, point (5,7) lies on the line [tex]y=2x-3[/tex].

All three point (3,3), (4,5), (5,7) satisfy the given equation.

Therefore, jayla is correct. Hence proved.

Answer:

The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)

Step-by-step explanation:

To find the inverse of a function switch x and y

Example:

If f(x) = {(1, 2), (-4, 5), (0, 0)}

To find its inverse switch x and y in each ordered pair

The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}

Let us do the same with our question

∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}

→ Switch x and y coordinates in all ordered pair

∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}

Look at the answer to find the correct choice

It is (A)

Answer:

The slope is 1/4

Step-by-step explanation:

Use rise over run.

To get to the point (4, -3) from (0,4)

You will have to rise 1, then run over 4.

Thus, slope is 1/4

Step-by-step explanation:

-253-1+352=10x+1

99=10x

99/10=x

9,9 = x

Answer: 1 1/10 or 11/10

Step-by-step explanation: 1/2 x 5/5 = 5/10 and 3/5 x 2/2 = 6/10 so 5/10 + 6/10 = 11/10.

Answer:11.99%

Step-by-step explanation:

The Actual present value is $85.74.

Fees associated with the loan are not included in the interest rate. The cost of borrowing money each year, including fees, is stated as an annual percentage rate (APR).

We have,

Christina is considering buying a new car with a sticker price of $23,599.

Total cost = (107.25 x 79.95)/ 100

                 = $ 85.74

Another method.

The cost is 100%.

After tax = 100% + 7.25%

               = 107.25% of 79.95

               = $85.74

Answer: 1

Step-by-step explanation: 45/50=90/100 which is closer to 1 than 1/2 or 0.

I assume the equation is

[tex]\dfrac6{x^2+2x-15}+\dfrac7{x+5}=\dfrac2{x-3}[/tex]

Notice that

[tex]x^2+2x-15=(x+5)(x-3)[/tex]

so to get each fraction to have a common denominator, we need to rewrite

[tex]\dfrac7{x+5}=\dfrac{7(x-3)}{(x+5)(x-3)}=\dfrac{7x-21}{x^2+2x-15}[/tex]

and

[tex]\dfrac2{x-3}=\dfrac{2(x+5)}{(x+5)(x-3)}=\dfrac{2x+10}{x^2+2x-15}[/tex]

So we have

[tex]\dfrac6{x^2+2x-15}+\dfrac{7x-21}{x^2+2x-15}=\dfrac{2x+10}{x^2+2x-15}[/tex]

Combine the fractions and put them on one side:

[tex]\dfrac{6+(7x-21)-(2x+10)}{x^2+2x-15}=0[/tex]

If x ≠ -5 and x ≠ 3, we can ignore the denominator, leaving us with

[tex]6+(7x-21)-(2x+10)=0[/tex]

[tex](6-21-10)+(7x-2x)=0[/tex]

[tex]-25+5x=0[/tex]

[tex]5x=25[/tex]

[tex]x=\dfrac{25}5=\boxed{5}[/tex]

Answer:

[tex]\displaystyle A+B=-\frac{5}{4}[/tex]

Step-by-step explanation:

The Number Line

Let's call

[tex]\displaystyle A=-4\frac{1}{2}[/tex]

[tex]\displaystyle B=+3\frac{1}{4}[/tex]

Both numbers are given as mixed fractions. Let's convert them to improper fractions:

[tex]\displaystyle A=-4\frac{1}{2}=-(4+\frac{1}{2})=-\frac{8+1}{2}=-\frac{9}{2}[/tex]

[tex]\displaystyle B=3\frac{1}{4}=3+\frac{1}{4}=\frac{12+1}{4}=\frac{13}{4}[/tex]

The decimal values are A = -9/2=-4.5, B=13/4 = 3.25

Now represent the points in the number line. See the image below

Finally, calculate their sum:

[tex]\displaystyle A+B=-\frac{9}{2}+\frac{13}{4}[/tex]

[tex]\displaystyle A+B=-\frac{18}{4}+\frac{13}{4}=\frac{-18+13}{4}[/tex]

[tex]\boxed{\displaystyle A+B=-\frac{5}{4}}[/tex]
