Is the function increasing or decreasing over the interval (-3,-1)? Explain.
Answers
Explanation:
The curve is going downhill as you move from left to right, and as you move from x = -3 to x = -1.
The interval notation of (-3,-1) means -3 < x < -1.
Since the curve is going downhill on this region, this means the function is decreasing on this interval.
Yes, the function is decreasing over the interval (-3,-1).
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given interval is (-3, -1).
The curve is going downhill as you move from left to right, and as you move from x = -3 to x = -1.
The interval notation of (-3,-1) means -3 < x < -1.

A car was bought for £18,000.
It was sold for £15,300.
Express this as a percentage decrease.
Answers
Answer:
15%
Step-by-step explanation:
when 18000 is 100%, 10% is 1800. So to make 15300 we need 8.5 1800s. So 85% of 18000 is 15300 so the rest is 15%. The answer is 15%
Answer:
15%
Step-by-step explanation:
[ (18,000-15,300) / 18,000 ] x 100
= (27,00 / 18,000) x 100
= 0.15 x 100
= 15%

-2x + 8 = y
3x - y = 22
How do I solve it
Answers
answer
x=6, y=-2
explanation
-2x + 8 = y -------equ 1
3x - y = 22 -------equ 2
u can use any of the simultaneous equation method
using elimination method
rearrange first from -------equ 1
-2x+8=y
-y-2x=-8
multiple through by -1
y+2x=8 -------equ 3
rearrange first from -------equ 2
3x-y=22
-y+3=22 ------equ 4
equate 3 and 4, adding them together
y+2x=8 -------equ 3
-y+3=22 ------equ 4
0+5x=30
5x=30
x=6------equ 5
replace 6 for x in any equation
using -------equ 3
y+2x=8
y+2(5)=8
y+10=8
y=8-10

Answer:
(x, y)=(6, -4)
Step-by-step explanation:
-2x+8=y
3x-y=22
Substitute the given value of y into the equation 3x-y=22
3x-(-2x=8)=22
Solve the equation for x
x=6
Substitute the given value of x into the equation 3x-y=22
3x6-y=22
Solve the equation for y
y=-4
The possible solution of the system is the ordered pair (x, y)
(x, y)=(6, -4)
Check if the given ordered pair is the solution of the system of equations
-2x6+8=-4
3x6-(-4)=22
Simplify the equalities
-4=-4
22=22
Since all of the equalities are true, the ordered pair is the solution of the system
(x, y)=(6, -4)

Answers
Answer:
probability of blue =5/20=1/4
Step-by-step explanation:
probability of yellow=4/20=1/5
Probability of selecting a blue colour then a yellow colour is, 1/19.
What is conditional probability?Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
Given, A bowl containing 4 yellow, 6 orange, 3 green, 5 blue, 2 brown colors.
Let P(A) be the probability of selecting a blue colour.
∴ P(A) = N(B)/N(S).
P(A) = 5/20.
P(A) = 1/4.
Let P(B) be the probability selecting a yellow colour is = 4/19.
As we replacement is not allowed.
∴ Probability of selecting a blue colour then a yellow colour is,
= P(B)×P(A).
= 4/19×1/4.
= 1/19.
