OA A system of two linear inequalities is different from a system of two linear equations. It is not possible to have no solution for a system of two linear
inequalities while a system of two linear equations it is
OB. A system of two linear inequalities is different from a system of two linear equations. A system of two linear inequalities does not have to be equivalent to
have infinitely many solutions while a system of two linear equations does need to be equivalent.
OC. A system of two linear inequalities is different from a system of two linear equations. The solution to a system of two linear inequalities is the point of
intersection while the solution to a system of two linear equations is a shaded region
OD. A system of two linear inequalities is different from a system of two linear equations. A system of two linear inequalities always has more than one solution
while there can only be one solution to a system of two linear equations
Answer:
i would say D two linear inequalities always have more than 1 solution while equations only have 1
Option D is correct. A system of two linear inequalities always has more than one solution while there can only be one solution to a system of two linear equations.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
We need to check How is a system of two linear inequalities in two variables different to a system of two linear equations in two variables
A linear inequality is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality.
A system of linear equations is usually a set of two linear equations with two variables.
A system of two linear inequalities is different from a system of two linear equations. A system of two linear inequalities always has more than one solution while there can only be one solution to a system of two linear equations.
Hence, option D is correct. A system of two linear inequalities always has more than one solution while there can only be one solution to a system of two linear equations.

A forest has 6500 trees.
The trees are beech or maple.
number of beech : number of maple = 1.6:1
(a) What fraction of the trees are beech?
Answer:4000
Step-by-step explanation:
Given
There are a total of 6500 trees
The ratio of beech and maple is [tex]1.6:1[/tex]
So, no of beech are [tex]\frac{1.6}{2.6}\times 6500=4000[/tex]
no of maple are [tex]\frac{1}{2.6}\times 6500=2500[/tex]

Find the equation of the line use exact numbers
Y=_x+_
Answer:
Y = 2x + 4
Step-by-step explanation:
y= mx +b
First, find m (aka the slope)
[tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{1}[/tex] = 2
m = 2
Find b (aka the y-intercept)
The line touches the y-axis at (0,4). Therefore b = 4
Plug m and b into the slope-intercept equation
y = mx +b
y = 2x + 4

-3.03
Step-by-step explanation:
divide -18.18 by 6
Answer:
t= -3.03
Step-by-step explanation:
In order to solve for t, we need to isolate it. We would do this by dividing both sides by 6:

number multiplied by a fraction is not always smaller than the original number. Explain this and give at least two examples to support your thinking.
Answer:
Sometimes, fractions can be written in 'improper' form, meaning that the top number (numerator) is bigger than the bottom number (denominator). So anything multiplied by a fraction like this will give a bigger number.
For example:
5 × 2/1 = 10
10 x 10/1 = 100
Step-by-step explanation:
Answer:
Step-by-step explanation:
There are two cases where this is true. When the fraction has the same numerator and denominator, or when the numerator is much larger than the denominator.

Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Beth will cycle a distance of 85.169 miles in the third week.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.
Beth rides her cycle 56 kilometers each week on average.
For the next three weeks, she will increase her distance by 15% each week.
As per the given condition, the required solution would be as
⇒ 56 / 100 = 0.56
⇒ 0.56 × 15 + 56 = 64.4
If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.
Repeat for the remaining three weeks.
⇒ 64.4 / 100 = 0.644
⇒ 0.644 × 15 + 64.4 = 74.06
⇒ 74.06 / 100 = 0.7406
⇒ 0.7406 × 15 + 74.06 = 85.169
Therefore, she will cycle a distance of 85.169 miles in the third week.

To find:
The value of [tex]b^2[/tex].
Solution:
We have,
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
On cross multiplication, we get
[tex]a\times c=b\times b[/tex]

Calculate 48 x 3/8 choose the numbers to complete the equation
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.
