9. If f(x) = 5x-4 and f(2a) =156 , then what is the value of a?

Answer:

Mario's unit rate is 5/1

Step-by-step explanation:

We know that Mario walks 5/6 miles per 10 minutes.

We need to find out how many miles Mario walks in 60 minutes (1 hour).

10 * 6 = 60. Which means that we must multiply 5/6 by 6.

[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]

30/6 = 5

Mario walks 5 miles per hour.

To put this in to a unit rate we must put this is a fraction:

[tex]\frac{Miles}{Hour}[/tex]

Substitute:

5/1

Answer:

Mario's unit rate is given by 900 miles/hour

Step-by-step explanation:

We have been given that Mario walked at a rate of 2/3 miles every 10 minutes

We have the relation between speed, time and distance, which is given by

speed = distance/Time

we have,

distance = 2/3 miles

Time = 10 minutes

On substituting these values in above formula, we got

speed 2/3 /10

speed 2/10.3

We have to find the unit rate in mile per hour, so we need to multiply it by 60

Thus, unit rate is given by

1/15 X 60

= 4 miles/hour

Answer:

Swimming

The type of activity that Jeff does at a speed of 4.5 miles per hour is Swimming

Answer:

3i

Step-by-step explanation:

i equals -1, the square root of 9 is 3

-1 times 3 times 3 is -9

Using the slope and intercept formula, the slope and y - intercept values of the graphed data are 3/2 and 3 respectively

Given the data :

Weeks, w ___ Weight in ounces, u

0 __________ 3

3 _________ 7.5

6 __________12

9 _________16.5

The y - intercept :

From the table given, the initial weight of the kitten (weight at week 0) = 3 ounces

Hence, the intercept is 3 ounces.

2.)

The slope :

Rise = y2 - y1 = (16.5 - 3) = 13.5

Run = x2 - x1 = 9 - 0 = 9

Slope = 13.5 / 9 = 1.5

Therefore, the slope is 1.5

Answer: y = -3.5x - 4.5

suppose: the equation of the line is y = ax + b ( a ≠ 0 )

because the line passes through (-2;2.5) => 2.5 = -2a + b

the line passes though (0;-4.5) => -4.5 = b

=> b = -4.5

   2.5 = -2a + b

=> a = -3.5

    b = -4.5

=> the equation of the line is y = -3.5x - 4.5

Step-by-step explanation:

the answer is the same

The value of x is (2w - t)/5.

The value of w is (5x + t)/2.

The value of t is  2w - 5x.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

5x - 2w + t = 0

Solve for x.

5x - 2w + t = 0

5x = 2w - t

x = (2w - t)/5

Solve for w.

5x - 2w + t = 0

5x + t = 2w

w = (5x + t)/2

Solve for t.

5x - 2w + t = 0

t = 2w - 5x

Thus,

The value of x, w, and t is given above.
