Timmy's expression is wrong

If you do this expression 5(x+2) the results are gonna be 5x+10. If Timmy did the expression like 5x+2, the expression is going to stay like this because that is the result, you can't do anymore after that.

5x+2 ≠ 5(x+2)

No es correcto por que en la primera ecuación 5 afecta a X y a 2 , pero en la segunda 5 solo afecta  x

Joaquin and Trisha are playing a game in which the lower median wins the game. Their scores are shown below. Joaquin's scores: 7
alekssr [168]

Answer:

Step-by-step explanation:

Given

Joaquin's score is 75,72,85,62,58,91

and Trisha's score is 92,90,55,76,91,74

Arranging score in order of value we get

Joaquin's : 58,62,72,75,85,91

Trisha's : 55,74,76,90,91,92

as no of values is even therefore their median is

Joaquin's=\frac{72+75}{2}=73.5

Trisha's =\frac{76+90}{2}=83

Therefore median of Joaquin's is lower

Thus Joaquin wins the game

Graph f(x)=−3/4x−4 . Use the line tool and select two points to graph the line.
lions [1.4K]

Answer:

Two points on the line would be (0, -4) and (4, -7)

Step-by-step explanation:

In order to find this, we can start at the y-intercept. The y-intercept is the constant at the end of the equation. In this case it is -4, which gives us the first point of (0, -4).

We can find the second point by using the numerator of the slope to determine how much we go up or down (-3) and the denominator for how much we go left to right (4). So we add the 4 to the x value and add the -3 to the y value.

(4, -7)
