17
Step-by-step explanation:
bc
In order to answer, you need to sketch the given exponential curves and straight lines and ask yourself if and when do they cross each other:
a) 2ˣ + 1 is an esponential curve with base >1 shifted up by 1;
-3x + 6 is a straight line with negative slope, shifted up by 6;
They cross each others only one time.
b) 3ˣ - 3 is <span>an esponential curve with base >1 shifted down by three, thus it can be negative;
2x - 2 is </span><span> a straight line with positive slope shifted down by 2;
They cross each others twice.
c) -4</span>ˣ - 1 is <span>an esponential curve with base >1 flipped over the x axis and shifted down by 1;
3</span>⁻ˣ - 2 is an esponential curve with base <1 ( 3⁻ˣ = (1/3)ˣ )and shifted down by 2;
They never cross each others.
Therefore the correct rder is:
-4ˣ - 1 = 3⁻<span>ˣ - 2
</span>-3x + 6 = 2<span>ˣ + 1
</span>3<span>ˣ - 3 = 2x - 2</span>
Solution: The venn diagram will be completed as shown in the given figure.
Explanation:
There are many types numbers. The set of numbers are defined below.
Complex Numbers: The complex are the addition of real and imaginative numbers. it is represented as a+bi, where a is a real number and b is an imaginary number.
Imaginary Numbers: The imaginary numbers are those numbers which are not real numbers. For example
.
Real Numbers: All numbers in the number system( fractional, roots, positive, negative, decimal, etc) are real numbers. For example 2.1 and 5 etc. Real numbers are categorized in two parts rational and irrational numbers.
1) Irrational numbers: The number which can't expressed in the form of are called irrational numbers. For example
and
etc.
2) Rational numbers: The number which can be expressed in the form of are called irrational numbers. For example 5 and -5.2 etc. It is categorized in two parts fractional and integer numbers.
3)Integer numbers: The rational number which has no decimal value is called integer numbers. For example-8,-2, 0, 5,7 and 100 etc.
4) Whole Numbers: The set of all positive integers including 0 is called known as the set of whole numbers.
5) Natural Numbers: All Whole numbers except 0 are known as natural number.
Answer:
original price= $150, sale price= $105
Step-by-step explanation:
since it is on sale for 70% of original price, there is 30% off discount.
$45 is 30% of original price (original price is 100%)
1% of original price
= $45 ÷ 30
= $1.50
original price
= $1.50 × 100
=$150
sale price (70% of original price)
= $1.50 × 70
= $105
