Y= -1/3x +5

5 is the y-intercept (where the line touches the y-axis) and -1/3 is the slope (rise over run, but since its negative, you go down 1, over 3 to the right) Hope this helps!!!

What value of a in the equation ax − 4 = 2y would give a line with a slope of 2?

sukhopar [10]

Answer:

a=4

Step-by-step explanation:

ax − 4 = 2y

We need to get the equation is slope intercept form y= mx+b.

Lets solve for y

Divide each side by 2

a/2 x - 4/2 = 2y/2

a/2 x -2 = y

or y=a/2 x -2

The slope is a/2 and the y intercept is -2

We want a slope of 2 so a/2 =2

a/2=2

Multiply each side by 2

a/2 * 2 =2*2

a =4

Wilbur and eugene are selling cheesecakes for a school fundraiser customers can buy french silk cheesecakes and apple cheesecake

elixir [45]

Answer:

one french silk cheesecake = $7

one apple cheescake = $20

Step-by-step explanation:

Let the cost of one french silk cheesecake be represented by a

Let the cost of one apple cheescake be represented by b.

We are told that wilbur sold 13 french silk cheesecakes and 12 apple cheesecakes for a total of $331 . This can be written as:

13a + 12b = 331 .......... equation i

Eugene sold 2 french silk cheesecakes and 3 apple cheesecakes for a total of $74. This can be written as:

2a + 3b = 74 ........ equation ii

13a + 12b = 331 .......... equation i

2a + 3b = 74 ........ equation ii

Multiply equation i by 2

Multiply equation ii by 13

26a + 24b = 662 ......... equation iii

26a + 39b = 962 ......... equation iv

Subtract equation iv from iii

-15b = -300

b = 300/15

b = 20

The cost of one apple cheescake is $20.

From equation ii,

2a + 3b = 74

2a + 3(20) = 74

2a + 60 = 74

2a = 74 - 60

2a = 14

a = 14/2

a = 7

The cost of one french silk cheesecake is $7.

The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .

let's solve for area of rectangle :

$➢ \: \: length \times width$

$\longrightarrow8 \times 3x$

$\longrightarrow24x$

Now, Area of Triangle :

$➢ \: \dfrac{1}{2} \times base \times height$

$\longrightarrow \dfrac{1}{2} \times 4 \times x$

$\longrightarrow2x$

So, the area of the shaded region in terms of x :

$\longrightarrow24x - 2x$

$\longrightarrow22x$

And since, Area of Shaded region = 44 cm²

By equating the area, we get

$\large \boxed{ \boxed{22x = 44}}$

Value of x = 2
