Answer:
£349.35
Step-by-step explanation:
okay so firstly add the % to 100 = 170
then do 170 divided by 100 and multiply by the total ($205.50)
this would give you $349.35 <----- this is your orignal price (before the sale 70% off)
[ (52.65 * 5) + 46.25 - 16.25] * 1/6
[ 263.25 + 46.25 - 16.25] * 1/6
293.25 * 1/6 =
293.25/6 =
48.875
error occurred in step 3....he multiplied by 6 instead of multiplying by 1/6
Answer:
2.16
Step-by-step explanation:
Hey so we know that product means multiplication and “less than” means subtraction
So
5 less than=5-
Product of 6 and a number=6*x
So
6x-5=8
(Since it says 5 less than a product of 6 and a number, we know that we have to subtract 5 from 6x, NOt the other way around)
Add 5 on both sides:
6x=13
Divide by 6
X=2.16
Hope this helps!
Answer:
<h3>Question 1</h3>
<u>Function given:</u>
<u>In the vertex form:</u>
- y = x² + 4x + 4 - 8 = (x + 2)² - 8
Axis of symmetry is the vertical line passing through the vertex.
<u>The vertex is</u>
<u>Axis of symmetry is </u>
<u>y- intercept is </u>
- x = 0 ⇒ y = -4, so the point (0, -4)
<u>Two other points are</u>
- x = 1 ⇒ y = (1 + 2)² - 8 = 9 - 8 = 1, the point is (1, 1)
- x = -1 ⇒ y = (-1 + 2)² - 8 = 1 - 8 = -7, the point is (-1, -7)
<em>See the graph with all the points plotted</em>
<h3>Question 2</h3>
<u>Function given:</u>
<u>In standard form:</u>
<u>In vertex form:</u>
- y = - 2x² + 4x - 2 + 8 = -2(x - 1)² + 8
<u>The vertex:</u>
<u>Axis of symmetry is </u>
<u>y - intercept </u>
- x = 0 ⇒ y = -2(-1)² + 8 = -2 + 8 = 6, the point is (0, 6)
<u>Two other pints:</u>
- x = -1 ⇒ y = -2(-1 - 1)² + 8 = -8 + 8 = 0, the point is (-1, 0)
- x = 2 ⇒ y = -2(2 - 1)² + 8 = -2 + 8 = 6, the point is (2, 6)
