Question:

A shop is having a sales all items are reduced by 25%. Work out the sale price of an item normally priced at £60?

Answer:

The new price is £45

Step-by-step explanation:

Given

Sales\ price = \pounds 60

Rate = 25\%

First, calculate the reduction

Reduction = Rate * Sales\ price

Reduction = 25\% * \pounds 60

Reduction = \pounds 15

The new price is:

New = Sales\ price - Reduction

New = \pounds 60 - \pounds 15

New = \pounds 45

What is the slope and y intercept of -2x +3y=-9
attashe74 [19]

Answer:

m = 2/3

b = -3

Step-by-step explanation:

Rearrange the equation to slope-intercept form (y = mx + b).

x and y are points on the graph.

m is the slope.

b is the y-intercept.

Isolate "y". This means separating it from the other numbers.

-2x +3y = -9

-2x + 2x +3y = -9 + 2x    Add 2x to both sides

3y = 2x - 9

3y/3 = 2x/3 - 9/3      Divide both sides by 3

y = 2x/3 - 9/3      Simplify

y = (2/3)x - 3

Think about which numbers and "m" and "b" now that the equation is in y = mx + b. Include the plus and minus signs.

m = 2/3

b = -3

How can I solve this?
Mnenie [13.5K]
X-1/3 = y-2/4
4(x-1) = 3(y-2)
4x-4 = 3y-6
4x-3y = -2 --->1
4x +3y =8 ---->2
2-1 ; 6y = 10
y = 10/6 or 5/3
And 4x + 3(10/6) = 8
4x =3
X = 3/4

A parabola can be represented by the equation x2 = 2y. What are the coordinates of the focus and the equation of the directrix?
SOVA2 [1]
The standard equation for a parabola that opens upward parallel to the y-axis is x2=4ay, where a = distance from the vertex to focus. Vertex is at origin(0,0)
4a=2
a=2/4
a=1/2 or 0.5
the coordinate of the focus is (0, 1/2)
the equation of the directrix is y=-1/2
