Hey there!!

Formula - y = mx + b

Where m = slope

Equation given : 2x + 4y = 12

...2x + 4y = 12

...4y = 12 - 2x

... y = 12 - 2x / 4

... y = 12 / 4 - 2x/4

... y = 3 - x / 2

... y = -x/2 + 3

Hence, the slope is -1/2

Hope my answer helps!!

Hello!

To find the slope of the given equation, we would need to convert this equation from standard form into slope-intercept form. Our goal, is to get the variable y, on one side of the equation.

Remember that slope-intercept form is written as y = mx + b. In this form, m is the slope and b is the y-intercept.

2x + 4y = 12 (subtract 2x from both sides)

4y = 12 - 2x (divide both sides by 4)

y = 12/4 - 2/4x → y = -1/2x + 3

Therefore, the slope of this equation is -1/2, which is the final choice listed.

A recipe uses 1 1/4 cups of milk to make 10 servings if the same amount of milk is used for each serving how many servings can b

aev [14]

Answer:

128 servings

Step-by-step explanation:

5/4 cups of milk for 10 servings is equal to 1/8 cup per 1 serving

there are 16 cups in a gallon

let 'n' = # servings in a gallon

so 1/8 : 1 is 16 : n

1/8n = 16

n = 16(8)

n = 128

If (−4, 11) and (−6, 5) are the endpoints of a diameter of a circle, what is the equation of the circle?

lora16 [44]

Answer:

A. $(x+5)^2+(y-8)^2=100$

Step-by-step explanation:

1. The standard form of the equation of a circle is $(x-h)^{2} + (y-k)^2=r^2$

2. To find the center we require the midpoint of the 2 given points

center = $[\frac{1}{2}(-4-6),\frac{1}{2}(11+5)]$

=(-5,8)

3. The radius is the distance from the centre to either of the 2 given points calculate the radius using the distance formula

d= $\sqrt{(x_{2}+x_{1})^{2} +(y_{2}-y_{1})^{2}$

let $(x_{1},y_{1})= (-5,8) \\$ and $(x_2,y_2)=(-4,11)$

r= $\sqrt{(-4+5)^2+(11-8)^2} =\sqrt{81+9}=10$

--> $(x-(-5)^2+(y-8)^2=10^2$

--> $(x+5)^2+(y-8)^2=100$

Find the value of x in similar polygons below

muminat

Answer:

Choice A

Step-by-step explanation:

When you have two shapes that are similar their sides are always proportional. So all we have to do is set up a proportion.

$\frac{18}{4.5}=\frac{x}{1.5}$

Now we cross multiply and solve

$27=4.5x\\x=6$

And that's it x equals 6 feet.
