Answer:
a) £210
b) £1651.38
Step-by-step explanation:
a)After the reduction, the price is 1 -30% = 0.70 of what it was.
0.7p = £147
p = £147/0.7 = £2.10 . . . price before decrease
__
b)After the increase, the price is 1 +9% = 1.09 of what it was.
p = £1800/1.09 ≈ £1651.38 . . . price before increase

Answer:
[tex]y= 3x+17; y= -\frac13x +\frac{11}3[/tex]
Step-by-step explanation:
First problem. If you want a parallel to a given line, you keep the slope.
Then we use the point-slope form of a line
[tex]y-y_0=m(x-x_0)[/tex] and we plug in there everything we need.
[tex]y-5=3(x+4) \rightarrow y=3x+12+5\\y=3x+17[/tex]
The second is quite similar. This time we want the perpendicular. It means that the product of the slopes has to be -1.
[tex]3\cdot m = -1 \rightarrow m=-\frac13[/tex]
At this point we have everything, let's replace and write down the line in a better looking form
[tex]y-5=-\frac13(x+4) \rightarrow y= -\frac13 x -\frac43 +5\\y= -\frac13x -\frac43 +\frac{15}3 \rightarrow y= -\frac13x +\frac{11}3[/tex]
Split 70 into the ratio 3:4? I don't understand ratio :(
Answer:
30:40
Step-by-step explanation:
Item A: item B : total
3 4 3+4
3 4 7
The total is 70
70/7 = 10
Multiply each item by 10
Item A: item B : total
3*10 4 *10 7*10

What is the slope-intercept form 10x-7y=-8
Answer:
Step-by-step explanation:

through: (5, 4), slope = undefined
write the slope intercept
Answer:
Step-by-step explanation:
An "undefined slope" is a vertical line going through the x axis at 5. The slope is undefined since there is no change in x for all values of y. The means the slope, which is the change in y divided by the change in x, would be a fraction with a zero denominator. This makes it undefined.
One value of x, in this case x=5, will include all possible values of y. There is no y-intercept, but the line has an x-intercept of 5.

A store buys 14 sweaters for $154 and sells them for $448. How much profit does the store make per sweater?
Answer:
Profit = $21
Step-by-step explanation:
14 sweaters = $154
Cost of 1 Sweater = 154 ÷ 14
= $11
New Cost for 14 Sweaters = $448
New Cost of 1 Sweater = 448 ÷ 14
= $32
Profit Per Sweater = 32 - 11
= $21
Full Profit = 448 - 154
= $294
Answer:
21

Find the coordinates of the point(s) of intersection between the following functions: y=x-1 and y=117/x-5
Answer:
(-8.-9) and (14,13).
Step-by-step explanation:
y=x-1
y=117/x-5
As the 2 terms in x are both equal to y:
x-1 = 117/x-5
(x-1)(x-5) = 117
x^2 - 6x + 5 - 117 = 0
x^2 - 6x - 112 = 0
(x + 8)(x - 14) = 0
x = -8, 14.
When x = -8, y = -8-1 = -9
When x = 14, y = 14-1 = 13.
The required coordinate points are (-8.-9) and (14,13).
Functions and valuesGiven the following equations
y=x-1
y=117/x-5
Equating both function will give
x-1 = 117/x-5
(x-1)(x-5) = 117
x^2 - 6x + 5 - 117 = 0
x^2 - 6x - 112 = 0
(x + 8)(x - 14) = 0
x = -8, 14.
When x = -8, y = -8-1 = -9
When x = 14, y = 14-1 = 13.
Hence the required coordinate points are (-8.-9) and (14,13).

What’s the value of x in this equation?
Answer:
20
Step-by-step explanation
trust me
Answer:
x = 20
Step-by-step explanation:
(5x + 35) + 45 = 180
These angles are opposites to each other so you know that together they equal 180.
Start off by adding 35 and 45. This gives you...
5x + 80 = 180
Then subtract by 80 giving you...
5x = 100
Then divide by 5. This gives you...
x = 20

P is the point of intersection of the lines with equations 5x — y = 1 and x + 2y = 9
Write down the coordinates of P.
Answer:
P = (1,4)
Step-by-step explanation:
First turn both equations to slope intercept form (y=mx+b).
5x - y = 1
Subtract 5x on both sides to get -y = -5x + 1, and since we want the y to be positive simply flip all the signs to get
y = 5x - 1.
x + 2y = 9
Subtract x on both sides to get 2y = -x + 9, then divide both sides by 2 to get
y = -1/2x + 9/2.
Now you can graph the two lines and see where they intercept each other. (I graphed them above for you⤴⤴⤴).
