coefficients for x ory:
45
The solution is
BN
Answer:
x = -2, y = 3
Step-by-step explanation:
Given equations are,
4x + 5y = 7 ---------(1)
3x - 2y = -12 ----------(2)
Multiply equation (1) by 3
12x + 15y = 21 ------(3)
Multiply equation (2) by (-4)
-12x + 8y = 48 --------(4)
Now add equations (3) and (4),
(12x + 15y) + (-12x + 8y) = 21 + 48
(12x - 12x) + (15y + 8y) = 69
23y = 69
y = 3
From equation (2),
3x - 2(3) = -12
3x - 6 = -12
3x = 6 - 12
x = -2
Therefore, x = -2 and y = 3 will be the answer.

Ben has 400 counters in a bag. He gives 35 of the counters to Sonia 130 of the counters to Phil 75 of the counters to Lance What fraction of the 400 counters is left in Ben’s bag? Give your fraction in its simplest form. (With workings out)
Answer:
2/5
Step-by-step explanation:
subtract 130,35,and 74 from 400 you will have 160/400 left then you find the greatest common and divide! and get 2/5
Answer: 2/5
Step-by-step explanation:
Ben gives 35 to Sonia, 130 to Phill, 75 to Lance, in total he gives away 240 counters. the fraction of the counters left in his bag would be 400-240 which is 160 and so his fraction would be 160/400 and this in simplest form would be 8/20 if you divide by 20 and then to simplify that you can divide by 4 to get 2/5

What is the inverse of the function f(x) = 4x + 8?
Answer:
f^-1(x) = (x-8)/4
Step-by-step explanation:
To find an inverse function, simply flip the x and y variables in a equation and then solve in terms of y.
x = 4y + 8
x - 8 = 4y
y = (x-8)/4

Answer : The area of given rectangle is p² - 7p
Step-by-step explanation :
Formula used to calculate the area of rectangle is:
Area of rectangle = length × breadth
Given:
Length = (p-7)
Breadth = p
Area of rectangle = length × breadth
Area of rectangle = (p-7) × p
Area of rectangle = p² - 7p
Therefore, the area of given rectangle is p² - 7p

Dadas as sequências identifique quais são PA e a sua razão (r): Lembre-se: para ser uma PA a diferença entre dois termos consecutivos são sempre os mesmos e é chamada de razão (r). A) (1, 1, 1, 1, ...) B) (-1, 0, 1, 2,...) C) (12, 48, 84, 120,...) D) (101, 202, 303, 404,...)
Answer:
A) 0
B) 1
C) 36
D) 101
Question:
Given the strings, identify which PA are and their reason (r): Remember: to be a PA the difference between two consecutive terms is always the same and is called the (r) ratio. A) (1, 1, 1, 1, ...) B) (-1, 0, 1, 2, ...) C) (12, 48, 84, 120, ...) D) (101 , 202, 303, 404, ...)
Step-by-step explanation:
PA is said to be the difference between two consecutive terms. The PA is always the same for these terms. It is also called the (r) ratio.
A) (1, 1, 1, 1, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = 1
2nd term = 1
PA = 1-1
PA = 0
B) (-1, 0, 1, 2, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = -1
2nd term = 0
PA = 0- (-1) = 0+1
PA = 1
C) (12, 48, 84, 120, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = 12
2nd term = 48
PA = 48 - 12
PA = 36
D) (101 , 202, 303, 404, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = 101
2nd term = 202
PA = 202 -101
PA = 101

Reflected across the x-axis => but then moved up 4 units
this makes it in a way "flipped"
We see a's coordinates = (-3, 3)
b's coordinates = (-1, 1)
c's coordinates = (-2, 3)
Hope this helps!
Answer:
Choice A
Step-by-step explanation:
Step 1 - reflection across x-axis, affects y-coordinate only
(x, y) ⇒ (x, -y)Step 2- 4 units up, affects y-coordinate only
(x, -y) ⇒ (x, -y+4)So for the given points we have:
A(-3, 1) ⇒ A'(-3, -1+4)= A' (-3, 3)B(-1, 3) ⇒ B'(-1, -3+4)= B' (-1, 1)C(-2, 1) ⇒ C'(-2, -1+4)= C' (-2, 3)Choice A is correct

x-1 divided by X^3-3x^2-x+3
Answer:
1 / (x + 1)(x - 3).
Step-by-step explanation:
x^3-3x^2-x+3
= x^2(x - 3) - 1(x - 3
= (x^2 - 1)(x - 3)
= (x - 1)(x + 1)(x - 3)
So x - 1 divided by x^3 - 3x^2 - x + 3
= (x - 1) / (x - 1)(x + 1)(x - 3)
= 1 / (x + 1)(x - 3).

In the Kite Club, there are a total of 17 kids. There are 5 more girls than boys. Write two equations and graph to find the number of girls in the club.
Answer:
6 boys and 11 girls
Step-by-step explanation:
hello,
let 's note x the number of boys and y the number of girls, we can write two equations
"there are a total of 17 kids"
(1) x + y = 17
"There are 5 more girls than boys"
(2) y = x + 5
We can replace (2) in (1) it comes
x + x + 5 = 17
<=> 2x = 17-5 = 12
<=> x = 6
and then y = 11
So, there are 6 boys and 11 girls
graphs below
hope this helps
The number of girls in the club is 6
What is an Equation ?An equation is a mathematical statement formed from two algebraic expression when equated by an equal sign.
It is given that
Total Kids = 17

There are 5 more girls than boys
Let number of girls be y
y = x+5
The number of girls = x +5
x +y = 17
The graph is plotted and is attached with the answer.
The intersection of the graph gives us the total number of girls and boys

The tires of a go-kart are 1 m1 \text{ m}1 m1, start text, space, m, end text in circumference. The tires revolve 15151515 times per second. What is the distance the go-kart travels in 40404040 seconds?
Answer:
600mStep-by-step explanation:
Distance traveled = speed*time taken
The total distance traveled around the tires is the circumference.
If the tire of a go-kart with circumference of 1m revolves 15 times per second, the speed of the go-kart will be 1*15 = 15m/s
Given the time taken by the go-kart to travel round to be 40 seconds;
Distance traveled by the go-kart = 15*40 = 600m

Answer:
75.36
Step-by-step explanation:
3.14 (a2 + ab)
Substitute a = 4 and b = 2 into the equation:
3.14 (4^2 + 4*2)
= 3.14 (16 + 8)
= 3.14 (24)
= 75.36
Answer:

Putting a = 4, b = 2
=> [tex](3.14)[(4)^2+(4)(2)][/tex]
=> [tex](3.14)(16+8)[/tex]

Determine the slope-intercept form of the equation of the line parallel to y = x + 11 that passes through the point (–6, 2). y = x +
Answer:
[tex]y = x+12[/tex]
Step-by-step explanation:
Parallel => This means it has the same slope as this one.
Slope = m = 1
Now,
Point = (x,y) = (-6,2)
So, x = -6, y = 2
Putting this in slope intercept form to get b
[tex]y = mx+b[/tex]
=> 2 = (1)(-6) + b
=> b = 2+6
=> b = 8
Now putting m and b in the slope-intercept form to get the required equation:
=> [tex]y = mx+b[/tex]
=> [tex]y = x+12[/tex]
Answer:
Now, I’m gonna assume that the equation is actually y = -4/3x + 11
The answer would be -4/3x - 6
Step-by-step explanation:
So since the line is parallel to the equation, y = -4/3x + 11, that means they have the same slope, so it’s -4/3x.
Using point-slope form, we can create an equation.
y - 2 = -4/3 (x + 6)
y1 = 2 and x1 = -6, we made it into +6 because subtracting a negative makes it addition.
Now our final equation would be y = -4/3x - 6
U.S. Population can be modeled by the function f(x)=165.6x^1.345, where f(x) is in thousand and x is the number of year after 1800. What is f(50) and what does it mean?
Answer:
f(50) = 31928.24 thousands
Therefore, it means that the US population in year 1850 is 31928.24 thousands
Step-by-step explanation:
Given the function;
f(x)=165.6x^1.345
Where;
f(x) is in thousand and
x is the number of year after 1800
To determine f(50), we will substitute x = 50 into the function of f(x);
f(50)=165.6(50)^1.345
f(50) = 31928.24 thousands
Since f(50) is the US population in year 1800+50 = 1850
Therefore, the US population in year 1850 is 31928.24 thousands
