Answer:
y=-3x
Step-by-step explanation:
3>2. It doesn't matter if some or all of the numbers are negative.
Answer: y = -3x has the steeper slope
==========================================
Explanation:
Any linear equation is of the form y = mx+b, where m is the slope.
For y = -2x, the slope is -2. For y = -3x, the slope is -3.
We just look at the number to the left of x to find the slope.
To figure out which slope is steeper, we simply look to see which slope value is furthest from 0 on the number line. A slope of 0 itself is completely horizontal and flat. As the slope value moves away from zero, in either positive or negative direction, then the slope gets steeper and steeper.
In short, a slope of -3 is more steep compared to a slope of -2. Therefore, y = -3x is the answer.
The graph below helps visually confirm that y = -3x is indeed steeper. We drop one extra unit down each time we move to the right one space.
15. A lamp is on sale at £22.05 This is a 10% reduction of the normal price. What was the price of the lamp before the reduction?
Answer:
£24.26 (rounded to 2dp) or full answ £24.255
Step-by-step explanation:
find 1% of 22.05= 0.2205
0.2205*10=2.205(10%)
add this to the 90%(£22.05+2.025)= 24.255
=24.26(rounded to 2dp)
The price of the lamp before the reduction will be £24.5.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The sale price of the lamp = £22.05
This is a 10% reduction of the normal price.
Now,
Let the price of the lamp before the reduction = x
So, We can formulate;
⇒ x - (10% of x) = £22.05
⇒ x - 10x/100 = £22.05
⇒ (100x - 10x)/100 = £22.05
⇒ 90x / 100 = £22.05
⇒ 90x = £22.05 x 100
⇒ 90x = £2205
⇒ x = £2205/90
⇒ x = £24.5
Thus, The price of the lamp before the reduction will be £24.5.

15. 65
Step-by-step explanation:
13.
If the average of two numbers is 1, then the sum of those two numbers is 2. As 2*1 is 2, and the average is found by dividing the sum by the amount of numbers.
Only one number is an integer and has a reciprocal that is an integer, the number being 1.
1/1 = 1
1/1 = 1
Average:
1+1 = 2
2/1 = 1
Therefore the answer is 1.

If we multiply everything by 7x, we'd get
7 + x = 49
subtract 7 on both sides
x = 42
15.
If
pg = 50 and gr = 15
then
pg + gr = 65
factoring that would give you
g(p+r) = 65

Step-by-step explanation:

(a) An angle measures 40°. What is the measure of its complement?
(b) An angle measures 63°. What is the measure of its supplement?
Answer:
see below
Step-by-step explanation:
Complements add to 90 degrees
x+40 = 90
x = 90-40
x = 50
Supplements add to 180
y+63 =180
y = 180-63
y = 117
If the sum of the measures of two angles is 90° they are known as complementary angles.
Let the value of unknown angle be x.According to the question
⇨x + 40° = 90°
⇨x = 90° - 40° [Subtract]
⇨x = 50°
Complement angle is 50°

Darias bought 5 school binders that cost $8.00 per
binder. If a back-to-school discount of 40% was
applied to his purchase, and then a 6% sales tax was
added, what was the total cost of the binders?
Answer:
$25.44
Step-by-step explanation:
First, you multiply, 5*8 = $40.00
Then you subtract the discout, 40-40% = $24.00
Lastly, you must add the sales tax, 24+6% = $25.44

[tex]x^4 \le f(x) \le x^2 \implies \displaystyle\lim_{x\to-1}x^4 \le \lim_{x\to-1}f(x) \le \lim_{x\to-1}x^2 \implies 1 \le \lim_{x\to-1}f(x) \le 1 \\\\ \implies \lim_{x\to-1}f(x)=1[/tex]
Andrew has a coupon for 20 % off of the price of any CD. If he purchases a CD originally priced at $16, what will the discounted price be?
Solve the above problem by using decimals.
Answer:
If you want to turn a percentage into a fraction divide by 100:
20%/100 = 0.2
0.2*16 = 3.2$
and if you want to turn a decimal into a fraction multiply by 100.
His discounted price will be 3.2$.

Percentage is the part of a whole given as a fraction of the hundred. The discounted price of the CD is $12.8.
Given information-
Andrew has a coupon for 20 % off of the price of any CD.
The price of the CD purchased by the Andrew is $16.
PercentagePercentage is the part of a whole given as a fraction of the hundred.
As the Andrew has a coupon of 20 percent, the 20 percent will be off whatever he buys. Now the discount price for the $16 priced CD is equal to the 20 percent of the 16. Thus the discount is,
[tex]d=\dfrac{16\times20}{100} \\ [/tex]
[tex]d=3.2[/tex]
Thus the discount on the CD is 3.2.
Now the discounted price of the CD is equal to the difference of the price of the CD and the discount. Thus the discounted price of the CD is,
[tex]P=16-3.2[/tex]
[tex]P=12.8[/tex]
Thus the discounted price of the CD is $12.8.

Sammy and Hannah are finalists in a cooking competition. For the final round, each of them will randomly select a card without replacement that will reveal what their star ingredient must be. Here are the available cards:
Cabbage
Spinach
Kale
Leeks
Carrots
Turnips
Cabbage
Leeks
Spinach
Carrots
Kale
Turnips
Sammy and Hannah both want to get leeks as their star ingredient. Sammy will draw first, followed by Hannah.
What is the probability that NEITHER contestant draws leeks?
Round your answer to two decimal places.
The probability that neither of them draws the Leeks card is P = 4/6 = 0.667
Here we can assume that all the cards have the same probability of being randomly drawn.
The cards are:
Cabbage Spinach Kale Leeks Carrots TurnipsSo we have 6 cards. We want to find the probability that neither contestant draws the "Leeks" card.
Sammy draws first, the probability of drawing the Leeks card will be equal to the quotient between the number of Leeks cards (one) and the total number of cards (6).
Then the probability of drawing the leeks card is p = 1/6
This means that the probability of NOT drawing the leeks card is:
q = 1 - 1/6 = 5/6.
Now draws Hanna, now there are 5 cards in the deck (because one was already drawn). With the same approach as before, the probability of drawing the Leeks card is p = 1/5, then the probability of NOT drawing the card is:
q = 1 - 1/5 = 4/5.
The joint probability (this is, the probability of both of these events to happen together) is just the product of the individual probabilities.
Then the probability that neither of them draws the Leeks card is:
P = (4/5)*(5/6) = 4/6 = 0.667

The polynomial is,
⇒ x² - x - 3 = 0
Now,
We can solve the equation as;
⇒ x² - x - 3 = 0
