Answer:

The slope is $\frac{1}{2}$ ; the Y-intercept is $-\frac{4}{3}$

Step-by-step explanation:

You can find the slope and the y intercept by looking at the equation

$y = mx + b$

The $\frac{1}{2}$ is right next to the x and comes right after the y = so that is the slope, and the y intercept is $-\frac{4}{3}$ because it is the number standing alone at the end of the equation.

Quadratic Equation

Step-by-step explanation:

The sum of ages of two friends is 13 years.

The product of their ages is 42.

Let the age of 1st friend and 2nd friend is x, y respectively.

1 st condition= The sum of ages of two friends is 13 yrs.

i.e x+y = 13........ (I)

2nd condition= The product of their ages is 42.

i.e X*y = 42........(ii)

From equation (I)

X+y = 13

or, X = 13-y........ (iii)

Putting the equation (iii) in equation (ii).

X*y= 42

(13-y) * y = 42

13y - y^2 = 42

${y}^{2} - 13y + 42 = 0$

${y}^{2} - (7 + 6)y + 42= 0$

${y}^{2} - 7y - 6y + 42 = 0$

$y(y - 7) - 6(y - 7) = 0$

$(y - 6) (y - 7) = 0$

Either; y-6 = 0

y = 6

Or;

y-7=0

y = 7

Keeping the value of y as "7" in equation (ii)

x*y = 42

7x = 42

X = 42/7

Therefore, the value of X is 6.

Therefore, either 1st friend is 6 years and 2nd is 7 years.

snow_lady [41]

1104 cups per 1 restaurant

There are FOUR boxes EACH containing 1656 cups, MEANING that you will do 1656 x 4, getting 6624.

You divide this by 6, and TADA!

Hope this helps!

Solve by simplifying the problem. There 18 students in Mr. Alvarez's art class . Throughout the year, every student must pair up

let each of these dots represent a student. once the first student has finished a project with everyone, cover it with your finger. then, the next student has to do a project with all the others, but not the one behind him, because the one behind him already did a project with him. Am I making sense?
