State the equation of the line which has the y-intercept :

aliina [53]

Answer:

A general line is written as:

y = a*x + b

where:

a is the slope

b is the y-intercept.

a) y-intercept = 2 and slope = 7.

This line is:

y = 7*x + 2

b) y-intercept = -1 and is parallel to y= 5x - 7.

Now, if two linear equations are parallel if they have the same slope and different y-intercept. Then if we want a line parallel to y= 5x - 7, this means that the slope of this line must also be equal to 5.

y = 5*x + (-1)

c) y-intercept 2 and is inclined at 45° to the x- axis.

When we have an inclination of A degrees from the x-axis, the slope of the equation is given by: a = Tan(A)

In this case, we have A = 45°

Then the slope is a = Tan(45°) = 1

Then the equation of this line is:

y = 1*x + 2

Katy makes 48 cookies an hour. If she has 24 alr, how long would it take her to make 120?

rosijanka [135]

Question:

Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?

Answer:

It takes 2.5 hours for Katy to make 120 cookies

Step-by-step explanation:

Given:

Time taken to make 48 cookies = 1 hour

To Find:

Time taken to make 120 cookies = ?

Solution:

Time taken to make 48 cookies = i hour

So now time taken to make 1 cookie = $\frac{1}{48} hour$

So time taken to make 120 cookies

= Number of cookies X time taken to make one cookie

=> $120 \times \frac{1}{48}$

=> $\frac{120}{48}$

=> 2.5 hours

What method would be best to use 53=4(x-3)^2-11

Veronika [31]

Answer:

x = 7 , -1

Step-by-step explanation:

<u>SOLUTION :-</u>

$4(x-3)^2-11 = 53$

Add 11 to both the sides.

$=> 4(x-3)^2-11+11=53+11$

$=> 4(x-3)^2 = 64$

Divide both the sides by 4.

$=> \frac{4(x-3)^2}{4} = \frac{64}{4}$

$=> (x-3)^2 = 16$

Root square both the sides.

$=> \sqrt{(x-3)^2} = \sqrt{16}$

$=> x-3 = +4 \; or -4$

Here , x will have two values -

1) $x-3 = 4$

$=> x = 4 + 3 = 7$

2) $x - 3 = -4$

$=> x = -4 + 3 = -1$

<u>VERIFICATION :-</u>

When x = 7 ,

$4(x-3)^2 - 11 = 4(7 - 3)^2 - 11$

$= 4 \times 4^2 - 11$

$= 4 \times 16 - 11$

$= 64 - 11$

$= 53$

When x = -1 ,

$4(x-3)^2 - 11 = 4(-1 - 3)^2 - 11$

$= 4 \times (-4)^2 - 11$

$= 4 \times 16 - 11$

$= 64 - 11$

$= 53$

Given the points below, find XY. Round to the nearest hundredth.<br> X(-8,4) and Y (4, -6)

stepan [7]

Answer:

15.62

Step-by-step explanation:

The length XY is found from the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((4 -(-8))² +(-6 -4)²) = √(12² +(-10)²) = √244

d ≈ 15.62 . . . units

The length of XY is approximately 15.62 units.
