Answer:

f(-2) = 13

Step-by-step explanation:

f(x) = -5x + 3

x = -2, so replace all x's with -2

f(-2) = -5(-2) + 3

f(-2) = 10 + 3

f(-2) = 13

A basketball player has 45 steals, 72 assists, 90 rebounds, and 432 points. What is
aalyn [17]

Answer:

5:24

Step-by-step explanation:

We're provided with the number of rebounds as 90 while the points are 432. Expressing them into ratio of rebounds to steals we have

90:432

Simplification:

Dividing both sides by 2 we obtain

45:216

Dividing both sides of the above ratio by 3 we obtain

15:72

Dividing both sides of the above ratio further by 3 we obtain

5:24

Therefore, rhe simplified ratio of rebounds ro steals is 5:24

Solve the system of linear equations by substitution
Bond [772]

Answer:

(-4, 5)

Step-by-step explanation (work shown in attached picture):

1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.

2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.

Since x = -4 and y = 5, the solution is (-4, 5).

A line is defined by the equation 2x+y -4. Which shows the graph of this line?
Nitella [24]

Answer:

Not sure if you mean 2x+y=-4 or 2x+y=4

either way put it in y=mx + b form (slope intercept)

Step-by-step explanation:

so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis

so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
