We have that
<span>y-x-4=0------> y=x+4
let
f(x)=y
so
f(x)=x+4-------> this is </span><span>the equation written in function notation, with x as an independent variable

the answer is
f(x)=x+4</span>

Joy is making a fruit salad. For every 2 cups of blueberries that Joy uses in the fruit salad, she uses 3 cups of strawberries.
Igoryamba

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

Step-by-step explanation:

Given,

Cups of blueberries used for 3 cups of strawberry = 2

Ratio of cups of blueberry to strawberry = 2:3

Joy wants to use 6 cups of blueberries.

Let,

x be the cups of strawberry for 6 cups of blueberries.

Ratio of cups of blueberries to strawberries = 6:x

Using proportion;

Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

2:3::6:x

Product of extreme = Product of mean

2*x=3*6\\2x=18

Dividing both sides by 2

\frac{2x}{2}=\frac{18}{2}\\x=9

Joy will need to use 9 cups of strawberries for 6 cups of blueberries.

How do I graph x - 4y &lt; 0
Temka [501]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

x-4y < 0

isolate the variable y

-4y < -x

Divide by -4 both sides

Remember

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

so

y > \frac{x}{4}

The solution of the inequality is the shaded area above the dashed line y=\frac{x}{4}

The slope of the dashed line is positive m=1/4

The y-intercept of the dashed line is (0,0)

The x-intercept of the dashed line is (0,0)

using a graphing tool

The graph in the attached figure

Can anyone help me with this and explain it too?
arlik [135]

Answer:

(6, 3)

Step-by-step explanation:

Midpoint (x_{m},y_{m})=(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2})\\\\=(\frac{3 + 9}{2}, \frac{6 + 0}{2})\\\\=(\frac{12}{2}, \frac{6}{2})\\\\Midpoint of a line segment (x_M, y_M) = (6, 3)

How to Calculate Midpoint?

The x-coordinate of the midpoint M of the segment \overline{AB} is the arithmetic mean of the x-coordinates of the endpoints of the segment  \overline{AB}. Similarly, the y-coordinate of the midpoint M of the segment  \overline{AB} is the arithmetic mean of the y-coordinates of the endpoints of the segment  \overline{AB}.
