4x squared plus 4y plus 3x plus 2y squared
Could anyone save my life??
Answer:
Step-by-step explanation:
y -5x = 2
10x -3y =9
substitute x for 3/5 and y for -1
-1 -(5*3/5) = 2
(10*3/5) -3(-1) =9
simplify :
-1 -3 =2
6+3 =9
-4 =2 Not true
9=9 True
Conclusion: the point (3/5, -1) is not a solution to the given system of equations

Look at this graph:
Determine whether the graph represents a function.
Answer:
true
Step-by-step explanation:
here this might help a little Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
Solve algebraically for all values of x:
- 4x^4 + 36x^3 - 80x2 = 0
Given:
The equation is
[tex]-4x^4+36x^3-80x^2=0[/tex]
To find:
The value of x.
Solution:
We have,
[tex]-4x^4+36x^3-80x^2=0[/tex]
It can be written as
[tex]-4x^2(x^2-9x+20)=0[/tex]
Splitting the middle term, we get
[tex]-4x^2(x^2-5x-4x+20)=0[/tex]
[tex]-4x^2(x(x-5)-4(x-5))=0[/tex]
[tex]-4x^2(x-5)(x-4)=0[/tex]
Using zero product property, we get
[tex]x^2=0,x-5=0,x-4=0[/tex]
[tex]x=0,x=5,x=4[/tex]
Therefore, the values of x are 0, 4 and 5.

What are functions?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
Given
f(x) = - x² + 6x -1
g(x)=3x² - 4x - 1
(f-g)(x) = - x² + 6x -1 -(3x² - 4x - 1)
(f-g)(x) = - x² + 6x -1 - 3x² + 4x + 1
(f-g)(x) = - 4x² + 10x
(f-g)(x) = - 4x²+ 10x

The value of x is 42 of three parallel lines intersected by two transversal lines
To solve for x in the given scenario of three parallel lines intersected by two transversal lines, we'll first determine the relationship between the corresponding angles.
According to the properties of parallel lines, corresponding angles are congruent. Thus, if we have an equation involving the corresponding angles, we can solve for x.
In this case, we have the equation:
x/35 = 30/25
To solve for x, we can cross-multiply:
25x = 30 * 35
25x = 1050
Dividing both sides by 25:
x = 1050/25
x = 42
Therefore, in the given scenario, the value of x is 42.

As an estimation we are told £3 is €4
Convert €90.50 to pounds give your answer rounded to 2 DP
Answer: £67.88
Step-by-step explanation:
From the estimation, we are informed that £3 = €4. This means that:
£1 = €4/3
Therefore, to convert €90.50 to pounds will then be:
= 90.50 ÷ 4/3
= 90.50 × 3/4
= 90.50 × 0.75
= 67.875
= £67.88

y=-3x + 10
y = -2x + 6
Substitution method
Answer:
x=4 and y=−2
Step-by-step explanation:
y=−3x+10;y=−2x+6
Step: Solve y=−3x+10for y:
Step: Substitute−3x+10foryiny=−2x+6:
y=−2x+6
−3x+10=−2x+6
−3x+10+2x=−2x+6+2x(Add 2x to both sides)
−x+10=6
−x+10+−10=6+−10(Add -10 to both sides)
−x=−4
-x/-1 = -4/-1 (Divide both sides by -1)
x=4
Step: Substitute4forxiny=−3x+10:
y=−3x+10
y=(−3)(4)+10
y=−2(Simplify both sides of the equation)
Answer:
Solution is the point (4, -2)
Step-by-step explanation:
use the expression for y from the first equation in the second equation:
then the equation y = - 2 x + 6 becomes:
- 3 x + 10 = - 2 x + 6
add 3 x to both sides
10 = 3 x - 2 x + 6
10 = x + 6
subtract 6 from both sides
x = 4
Now replace x with 4 in the first equation to find y:
y = - 3 x + 10 = - 3 (4) + 10 = - 12 + 10 = -2
Therefore this is the point solution to the system:
(4, -2)
how do u do this but in clear
Answer:
Look at the explanation :)
Step-by-step explanation:
Angle 2 and 3 are supplementary angles, which means they are equal.
Therefore, if
Angle 2 = 4x - 26
and
Angles 3 = 3x + 4,
It means that 4x - 26 = 3x + 4
Solve it,
4x = 3x + 30
x = 30
Input x to each angles,
Angle 2,
4(30) - 26 = 120 - 26 = 94
Angle 3,
3(30) + 4 = 90 + 4 = 94

Step-by-step explanation:
after completing the square what are the solutions to the quadratic equation below
x²-5x-6=3
Answer:
x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 5 x - 6 = 3
Hint: | Solve the quadratic equation by completing the square.
Add 6 to both sides:
x^2 - 5 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 61/4
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5/2)^2 = 61/4
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the first equation: Solve for x.
Add 5/2 to both sides:
x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the second equation: Solve for x.
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
