Answer:

The probability that Johnny caught a smallmouth bass is C. 1/4.

Step-by-step explanation:

The amount of largemouth bass is 3 times as many as the smallmouth bass, so, therefore, assuming there is 1 smallmouth bass, there would be 3 largemouth bass. The total number of bass is the number of largemouth bass added to the number of smallmouth bass, which is 4. Therefore, our whole (denominator) would be 4. Since there is 1 smallmouth bass in a group of 4 bass total, the probability is 1/4.

1/2 x + 13 = 9 (x Is Variable)
Elza [17]

Answer:

x= -8

Step-by-step explanation:

1/2x + 13=9

- move 13 to the other side

1/2x= 9-13

-simply 9-13

1/2x= -4

-multiply 2 on both sides

1x=-8

Write the equation of the line passing through the points (-4,-1) and (2,8)
klio [65]
<h3><u>Explanation</u><u>:</u></h3>
  • Calculate the slope with two given coordinate points by using rise over run.

m =  \frac{y_2 - y_1}{x_2 - x_1}

Let these points

\begin{cases}(x_1, y_1) = ( - 4,  - 1) \\ (x_2, y_2) = ( 2,  8) \end{cases}

m =  \frac{8 - ( - 1)}{2 - ( - 4)}  \\ m =  \frac{8 + 1}{2 + 4}  \Longrightarrow \frac{9}{6}  \Longrightarrow \frac{3}{2}  \\ m =  \frac{3}{2}

  • Slope-Intercept

y = mx + b \\ m = slope \\ b = y - intercept

Substitute the value of m in the equation.

y =  \frac{3}{2} x + b

  • Substitute any coordinate points that are given or part of the graph in the equation.

(x_, y) = ( - 4,  - 1)

- 1 =  \frac{3}{2} ( - 4) + b

  • Solve the equation for b-term.

- 1 =  \frac{3}{ \cancel{2}} ( \cancel{ - 4})   + b\\  - 1 = 3( - 2) + b \\  - 1 =  - 6 + b \\  - 1 + 6 = b \\ 5 = b

  • Rewrite the equation by substituting the value of b in the equation.

y =  \frac{3}{2} x + 5

<h3><u>Answer</u></h3>

\large \boxed{y =  \frac{3}{2} x + 5}
