1)

[tex]f(x) = 2x - 5\\f(4) = 2(4) - 5 = 8 - 5 = 3[/tex]

2)

[tex]f(x) = 2x - 5\\f(-6) = 2(-6) - 5 = -12 - 5 = -17[/tex]

3)

[tex]g(x) = x + 3\\g(8) = 8 + 3 = 11[/tex]

4)

[tex]h(x) = 4x\\h(5) = 4 \cdot 5 = 20[/tex]

5)

[tex]k(x) = x^2 + 2x - 5\\k(6) = 6^2 + 2 \cdot 6 - 5 = 36 + 12 - 5 = 43[/tex]

6)

[tex]k(x) = x^2 + 2x - 5\\k(-3) = (-3)^2 + 2(-3) - 5 = 9 - 6 - 5 = -2[/tex]

7)

[tex]g(x) = x + 3\\g(3x) = 3x + 3 = 3(x + 1)[/tex]

8)

Answer:

Time taken to travel at 3 miles = 1.875

Time taken to travel at 5miles = 1.125

Total distance = 11.25

Step-by-step explanation:

D = speed x time

Time = distance/speed

Time at 3 miles per hour and 5 miles per hour

T1 = d/3

T2 = d/5

Total time = 3 hours

T1+t2 = 3 hours

d/3 + d/5 = 3

= d(1/2+1/5) = 3

d(5+3/15) = 3

d(8/15) = 3

We cross multiply

8d = 45

d = 45/8

= 5.625 miles

Total distance = 2d

2x5.625 = 11.25 miles

Since d is now known

T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes

T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes

Total distance 2xd = 11.25

Answer:

the answer is

A. 1.875 hours

C. 5.625 miles

D. 11.25 miles

Answer:

x = -9

Step-by-step explanation:

First, subtract 3 from both sides of the equation and distribute the 3 to the x and -2.

3x - 6 - 2x = -15

Now, add the 6 to both sides of the equation and combine 3x and -2x.

x = -9

The value of x is -9.

Answer:

[tex]2187[/tex]

Step-by-step explanation:

[tex]\frac{3^3}{3^-^4}[/tex]

When attempting to solve this, we have to consider the exponent rule of fractional exponents:

[tex]\frac{x^a}{x^b} =x^a^-^b[/tex]

Therefore, our initial problem would become:

[tex]3^3^-^(^-^4^)\\[/tex]

Two negatives become positive:

[tex]3^3^+^4[/tex]

Add:

[tex]3^7[/tex]

[tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex]

[tex]= 2187[/tex]

Answer:

822.8 Words.

Step-by-step explanation:

First, divide 374 by 5 to find the amount of words "Julla" can type in 1 minute. This should give you 74.8 words. Then multiply this by 11 to find the amount of words "Julla" can type in 11 minutes. By doing this, we can get 822.8 words. You may want to round this up to 823 words.

Hope this helps! Let me know.

Answer:

x=3

Step-by-step explanation:

-1(-6x + 6) + 3 = 3 + 4x

6x - 6 + 3 = 3 + 4x

6x - 3 = 3 + 4x

2x - 3 = 3

2x=6

x=3

Answer:

x=3

Step-by-step explanation:

-(-6x+6)+3=3+4x

6x-6+3=3+4x

6x-3=3+4x

6x-4x=3+3

2x=6

x=6/2

x=3
