The answer would be the second option, "A household without children would consume about 1 quart of milk in a week."
This is because the y-intercept is the y-value when x = 0. Plug in the value 0 for x and you get the y-intercept. If x is 0, then there are no kids, but y = 1.03, so 1.03 quarts of milk would be consumed if there were no children.

Franco:
3x+2y=19
Caryl:
2x+4y=24

now use elimination

-2(3x+2y=19)
1(2x+4y=24)
=
-6x-4y=-38
2x+4y=24
add them together
which equals -4x=-14
divide both sides by -4
-4x/-4=-14/-4
x=7/2


we found x, so we subsitute it into the the original equation

3x+2y=19
3(7/2)2y=19
2y+21/2=19
-21/2 -21/2
2y=17/2
divide by 2 on both sides
2y/2= 17/2/2
y=17/4

so x= 7/2 and y= 17/4

If there’s a total of 210 fruit trees, and each tree produces 590 pounds a year, you multiply both those numbers and get 123,900 pounds a year.

In the calm waters of an inlet, Manon's boat moves with a velocity (speed and direction) vector \vec{b_1} = (3,4) b 1 ​ ​ =(3,4)
andrew-mc [135]

Answer with Step-by-step explanation:

We are given that

b_1=(3,4)

b_2=(1,1)

We have to find the speed of river's current and the direction of current flowing.

b=b_2-b_1=(1,1)-(3,4)=(-2,-3)

Speed of river's current=\mid b\mid

Speed of river's current=\sqrt{(-2)^2+(-3)^2}

Speed of river's current=\sqrt{13} m/s

By using the formula

\mid r\mid =\sqrt{x^2+y^2}

Direction of current flowing,\theta=tan^{-1}(\frac{y}{x})

\theta=tan^{-1}(\frac{-3}{-2})=56.3^{\circ}

The angle lies in third quadrant therefore

\theta=180+56.3=236.3^{\circ}
