Answer:

£100.80

Step-by-step explanation:

Lets start with the original price of the tickets.

£12 x 6 = £72

£6 x 3 = £18

£18 + £72 = £90

So now we know the tickets would have cost £90.

We now have to work out how much 10% is.

To do that, we have to divide by 10

90 / 10 = 9

10% = £9

Add that the the ticket cost.

£90 + £9 = £99.

Then we have the 2% for the credit card.

To get 2%, we first have to find 1%, which is found by dividing by 100

90 / 100 = 0.9

1%  = 0.90

0.9 x 2 = 1.8

2% = 1.80

Add that to the previous total and there's your answer.

<u>£99 + £1.80 =  £100.80</u>

Which of these equations are linear functions that go

Answer:

I don't think the answer exist

Step-by-step explanation:

for y=6x

when y=0, x=0 and when x=0, y=0

hence, (x,y)=(0,0)

for y=x+6

when y=0, x+6=0, x=-6 and when x=0, y=6

hence (x,y) = (-6,6)

for y=x^2+6

when x=0, y=6 and when y=0,

x^2+6=0

subtracting 6 from both sides

x^2=-6

take the square root of both sides and get

x=+ or -sqrt(-6)= + or - (2.45i)

i.e. x=+2.45i or x=-2.45i these are complex roots anyway, and its out of point.

for y=2x+6

when x=0, y=6 and when y=0,

2x+6=0,

2x=-6,

x=-3

the coordinates give (x,y)=(-3,6)

conclude....

Answer:

1) x ≤ -2;

2) x > 2;

3) x - 2 < 0

4) 2 ≤ x;

5)-2 < x;

Step-by-step explanation:

≤ means equal to or smaller than;

≥ means equal to or greater than;

< means smaller than;

> means greater than;

In addition, ≤ and ≥ are closed dots in the intervals. < and > are open dots in the intervals.

1) x ≤ -2; By looking at the intervals, the dot is -2, and the arrow is going to the left sides, -4, that the numbers were in a range of smaller than -2. And also because it's a closed dot, it means equal to or smaller than.

2) x > 2; The number starts in 2 with an open dot, and goes to 4, which means x in a range that greater than 2 but not equal to.

3) x - 2 < 0, we get x < 2, by plus 2 in both sides. The number starts in 2 with an open dot and goes to -4, which means x becomes smaller than 2 but not equal to.

4) 2 ≤ x; The number starts in 2 with a closed dot and goes to 4, the x is places in a number range that is equal to or greater than 2.

5)-2 < x; The number starts in -2 with an open dot and goes to 4, which means x becomes bigger than -2 but not equal to.

Andrews [41]
<span>Just draw 24 circles, or sticks, or stars, and then draw 10 little squares in a row twice, and 4 separate square. In the explanation say that there are 24 of whatever shape or thing you decided to draw and, for the regrouped say that 10+10+4=24 </span>
