There are 30 families. Two families have 4-5 pets. What percent of the families own 4-5 pets?

A video game has 25 levels. At level one, a player has 5 points. Each additional level increases the player's points by 10. If

ozzi

Answer:

B. (3,25)

Step-by-step explanation:

x = level of the video game

y = number of points

At level 1, a player has 5 points.

At level 2, the player has 5 + 10 = 15 points

Therefore, we can use the function notation this way:

f(x) = 5x + 10

The only ordered pair given that is from this function is:

B. (3,25)

f(3) = 5 * 3 + 10

f(3) = 15 + 10 = 25

The remaining three don't represent this function.

Calculate the axis of symmetry in the equation Y = (x+1) (x-4)

algol [13]

Answer:

Every parabola has a turning point called the axis of symmetry,so for this question you just have to find the turning points

x turning point= -b/2a,and the y turning point is gotten by replacing the value of x in the equation

y=(x+1)(x-4)

=x^2-3x-4

a is 1,b is -3 and c is -4

x= -(-3)/2(1)

=1.5

and y=x^2-3x-4

=1.5^2-3(1.5)-4

= -6.25

therefore the axis of symmetry is (1.5,-6.25)

I hope this helps

An instructor makes $15 more per hour than an assistant. If the combined hourly wage of the instructor and assistant is $65, wha

mezya [45]

X= assistant's wage
x+15= instructor's wage

Add their wages set equal to $65

x + (x + 15)= 65
combine like terms

2x + 15= 65
subtract 15 from both sides

2x= 50
divide both sides by 2

x= $25 assistant's wage

x+15= 25 + 15= $40 instructor's wage

ANSWER: (C) $25 hourly wage of assistant

Hope this helps! :)
