Answer:
2, 2.5, 3, 3.5
Even thought there are two "2's", you only list one making it 2,2.5,3,3.5 instead of 2,2,2.5,3,3.5
divide £64 in the ratio 3:5
Answer:
64/1 . 5/3
320/3
106.666666?
Answer:
£24 and £40
Step-by-step explanation:
To divide into the ratio of 3:5, we can start by dividing into 8 parts - as 3+5=8, then do 3 parts and 5 parts to achieve the ratio.
£64 / 8 = £8
3 * £8 = £24
5 * £8 = £40

The transformation shown is a rotation.
True or False
Use the linear combination method to solve the system of equations. *Explain each step of your solution.
2x - 3y = 13
x + 2y = 4
Step 1: We have the next system of equations -
[tex]2x - 3y = 13[/tex]
[tex]x + 2y = 4[/tex]
Step 2: Now, we will multiply by -2 the second equation:-
[tex] - 2(x + 2y) = 4[/tex]
[tex]→ - 2x - 4y = - 8[/tex]
Step 3: Then we add it :-
[tex]2x - 3y = 13[/tex]
[tex]( + ) \: - 2x - 4y = - 8[/tex]
Step 4: After finding the sum, we simplify:-
[tex] - 7y = 5[/tex]
[tex]→y = - \frac{5}{7} [/tex]
Then, substitute the above y value to find x's value in any equation of Step 1. Now, I used to second equation in Step 1:-
[tex]x = - 2( \frac{ - 5}{7}) + 4[/tex]
Step 5: Then simplify :-
[tex]y = \frac{38}{7} [/tex]
Therefore, the final answer is :-
[tex]x = \frac{38}{7} [/tex]
and
[tex]y = \frac{5}{7} [/tex]

Answer:
(5,-3)
Step-by-step explanation:
We can substitute the y in the second equation by the first equation:
2x+3(x-8)=1->
2x+3x-24=1 ->
5x-24=1 ->
5x=25 ->
x=5.
Then solve for y in the first equation:
y=5-8 ->
y=-3.
So the first is correct:
(5, -3)
Hope that helps! :)
Answer:
First option: (5,-3)
Step-by-step explanation:
First turn the second equation to slope intercept form (y=mx+b):
Subtract 2x on both sides to get 3y = -2x + 1, then divide 3 on both sides to get y = -2/3 x + 1/3.
Now you can graph both, and the solution would be the point that intercepts both of these lines.
(Here it is graphed above for you⤴⤴⤴)

Bacteria colonies can triple in size every 4 days. If you start with 150 bacteria microorganisms, how large would the colony be after 16 days? First, complete the equation: Future Amount = 150(1+[?]
Answer:
But notice that the colony tripled 4 times in 16 days, or it tripled 16 / 4 = 4 times.
Step-by-step explanation:
150 x 3 x 3 x 3 x 3 = 150 x 34 = 150 x 81 = 12,150.

What I Did:
First I turned them into whole number so I turned 0.6 into 6 and 4.8 into 48
Then I divided 48 by 6 which was 8
You can also add 0.6 as many times until you get to 4.8 but then you're just wasting time.

Which graph represents a linear function? (4 points)
Group of answer choices
A coordinate plane is shown with a line passing through the x-axis at negative 2 and the y-axis at negative 6.
A coordinate plane is shown with a curved line that starts in the bottom left area of the graph, passing through the point -1 comma -5, curving to pass through the y-axis at 2.5, then curving up again to pass through the point 1 comma 5
A coordinate plane is shown with a parabola graphed in an upward U shape. The bottom of the parabola touches the y-axis at -10 and curves upward on both sides
A coordinate plane is shown with a wavy line that sits on the x-axis and moves across the graph in even up and down waves.
A linear function is one of the most simplest form of functions. As the name "linear" indicates, a linear function is simply a line, more precisely a straight line.
So it is in the form of f(x) = ax + b.
Lets now check the possible answers : (second answer :) "a curved line", not correct.
(third answer:) "a parabola", this is not a straight line, so not correct.
(fourth answer:) "a wavy line", not a straight line, so not correct.
The only correct answer is the first one : a line passing through the x axis at negative 2 and the y axis at negative 6.

2. Using 50 for the number of weeks in a year is a(n) exponent
hundredths
overestimate
partial products
power
round
tenths
thousandths
underestimate
which one?
There are 52 weeks in a year.
Using 50 for the number of weeks in a year is a(n) round.
Rounding is a process which we approximate the known number by just scaling it up or down.
In rounding the numbers less than 5 are scaled to one number less than the given integer and numbers such as 5 or above than 5 are scaled a number greater than the given number .
For example if there were 55 or more than weeks in a year we can say there are approximately 60 weeks in a year.
But there are 52 weeks so we round it to 50 weeks as 2 is less than 5.
