Jack will spend a total of exactly $15 on Redbix movies and games. What equation in standard form can he use to graoh a line sho
alina1380 [7]

Answer:

1.25x+2.5y -15 = 0

Step-by-step explanation:

Total amount to be spent on Redbix movies and games = $15

Money to be paid for each movie = $1.25

Money to be paid for each game = $2.50

To find:

Equation in standard form that can be used to graph the line.

Solution:

First of all, let us learn about the standard form of equation of a line.

Standard form can be represented as:

Ax+By+C =0

Where A,B, C are constants.

Now, let us try to make equation.

Let number of movies bought = x

Amount to be paid for movies = $1.25x

Let number of movies bought = y

Amount to be paid for movies = $2.50y

Total money is $15.

Therefore, we can write the equation as:

1.25x+2.5y = 15

Standard form can be written as:

1.25x+2.5y -15 = 0

which function has real zeros at x = −10 and x = −6? f(x) = x2 16x 60 f(x) = x2 − 16x 60 f(x) = x2 4x 60 f(x) = x2 − 4x 60
LiRa [457]

Answer:

Option A is correct

The function x^2+16x+60 has real zeroes at x =-10 and x =-6

Explanation:

Given: The real zeroes or roots are x = -10, and x = -6

To find the quadratic function of degree 2.

x^2- (\alpha+\beta)x + \alpha\beta =0 where α,β are real roots.   ....[1]

Here, α= -10  and β= -6

Sum of the roots:

α+β =  -10+(-6) = -10-6 = -16

Product of the roots:

αβ = (-10)(-6)= 60

Substitute these value in equation [1] we have;

x^2-(-16)x+60 = x^2+16x+60

Therefore, the quadratic function for the real roots at x =-10 and x =-6 ;

x^2+16x+60

Please solve and show the steps. 2/3z +3 =7
USPshnik [31]
Subtract 3 from both sides:

2/3z=4

divide by 2/3 on both sides (multiple 3/2 on both sides)

z= 6
