The (f-g)(x) is- 4x²+ 10x
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

Answer:
Yes, SAS.
Step-by-step explanation:
For my education system, there isn't such thing as SAS, ASA or etc. I just had to search it up what it was.
Congruent angles are angles with the same shape and size. The two triangles are congruent if you look carefully, after that I searched up and saw the different rules of triangles. I think that SAS might be the correct answer.

Given:
A right angle triangle ABC, right angled at C.
To find:
The measure of θ.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
In triangle ABC,
[tex]\tan \theta=\dfrac{AC}{BC}[/tex]
[tex]\tan \theta=\dfrac{2.7}{5}[/tex]
[tex]\tan \theta=0.54[/tex]
It can be written as
[tex]\theta=\tan^{-1}0.54[/tex]
[tex]\theta\approx 28.369[/tex]
Therefore, the measure of θ is 28.369.

If the value of "y" varies directly with "X"
and y = -51 when x = 3, find "y" if x = 2.
Enter the number
Answer:
x : 3 :: y : -1
9 : 3 :: y : -1
3y = -9
y = -3
Answer:
-34
Explanation:
Y varies directly as x then the equation relating them is
y= kx ⬅️k is the constant of variation
To find k use the condition y= -51 when x=3
k= -17
y= -17x⬅️equation of variation
when x=2, then
y= -17*2=-34

please help with matrices
Answer:
(1/2) {ad - cb} both expressions
Step-by-step explanation:
Notice that the area of the triangle in question can be calculated as the area of the larger right angle triangle OSQ MINUS the area of the smaller right angle triangle OPR, and MINUS the area of the trapezoid RSQP.
Given the coordinates of the given points, the formulas for area of triangles and of trapezoid, we have the following area subtractions:
1/2 (a + c) (b +d) - 1/2 a* b - 1/2 c (b + b + d)=
= (1/2) { ab + ad + cb + cd - ab - 2 cb -cd } =
= (1/2) {ad - cb}
On the other hand the matrix expression is giving you 1/2 of the determinant of the given matrix such determinant is: ad - cb
Then we see that the equality is correct since (1/2) of the determinant is also :
(1/2) {ad - cb}

Answer:
Step-by-step explanation:
b
Answer:
C
Step-by-step explanation:
A shows the range of numbers greater than 1, not including 1 (the circle on the number 1 is empty, meaning 1 isn't included - when it's filled in then 1 is included).
B shows the range of numbers less than 1, not including 1.
C shows the range of numbers less than and including 1.
D shows the range of numbers greater than and including 1.
'≤' means 'less than or equal to'
We're looking for the range of numbers less than and including 1: C
is triangle abc ~ triangle def ?
Answer:
Unable to be determined.
Step-by-step explanation:
AA postulate : 2 corresponding angles that are congruent.
SSS theorem : 3 sides of a triangle that are equal to another triangle's 3 sides.
SAS postulate: 2 sides and their included angle are congruent to another triangle's 2 sides and their included angle.
This would seem to follow the SAS postulate at first, but the angle we are provided is not the included angle of the sides. In triangle ABC, we are analyzing lines AB and AC. Their included angle is A, but we are given the measure for angle B.
Same with DEF; we analyze DE and DF, who share angle A, but we are given angle E as a measure.
Therefore, we cannot determine if the triangles are similar or not.
In the diagram, the measure of angle 3 is 105°. A transversal intersects 2 lines to form 8 angles. Clockwise from the top, the angles are 1, 2, 3, 4; 5, 6, 7, 8. Which angle must also measure 105°?

Answer:
[tex]3\sqrt{2}[/tex]/2
Step-by-step explanation:
first we take the square root of the top and bottom:
[tex]\frac{\sqrt{72} }{\sqrt{16} }[/tex]
The denominator is 4. The numerator is harder to solve. To solve, we need to look at the factors of 72.
72= 8 * 9. This means that [tex]\sqrt{72} =\sqrt{8} *\sqrt{9} \\[/tex]
We know that the square root of 9 is 3, so now we have
[tex]\frac{3\sqrt{8} }{4}[/tex]
We're almost done!
Since 8= 2*4, and the square root of 4 is 2,
[tex]\frac{3*2*\sqrt{2}}{4}[/tex]
last, we simplify and get
[tex]\frac{3\sqrt{2}}{2}[/tex]
The average rate of change of f(x)= x^2- x + 4 from x =2 to x= 4

The variable q represents a positive integer. Does 3(59 + 9) + 5q represent a number that is greater than, less than, or equal to 4(59 + 6)? Show your work.
Thank you if you awnser this!
Answer:
Depends on the value of q.
Step-by-step explanation:
3(59+9) + 5q = 3(68) + 5q = 204 + 5q
4(59+6) = 260
The value of the inequality equation is 3(59 + 9) + 5q < 4(59 + 6) , when the value of q < 11.2
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the first number be p = 3(59 + 9) + 5q
Now , the value of a = 204 + 5q
And , let the second number be q = 4(59 + 6)
Now , the value of b = 260
Now , for the value of p and q to be equal ,
Substituting the values in the equation , we get
204 + 5q = 260
Subtracting 204 on both sides of the equation , we get
5q = 56
Divide by 5 on both sides of the equation , we get
q = 11.2
Now , when q < 11.2 , the value of a < b
Hence , the inequality equation is 3(59 + 9) + 5q < 4(59 + 6) , when q < 11.2

Bob has $24 more than twice as much as Susie,
Together they have $150.
using the equations created in
Answer:
150
Step-by-step explanation:
To solve this problem, first start setting up the equation.
Start with bob first - this is the easiest. Let x = bob
To get the part for susie - he has $24 more than twice the amount of bob, so his part of the equation would be set up as: 2x + 24
Combine these parts:
x + (2x + 24)
Combined they have $150, so you would set the equation above equal to 150
x + (2x + 24) = 150
Combine like terms:
3x + 24 = 150
Solve the equation for x
3x + 24 = 150
- 24 -24
3x = 126 isolate x by itself on one side of the equation
divide both sides by 3 to get x by itself
3x = 126
3 3
x = 42
Now that you have solved for x, you know the amount that bob has... $42
With this information you can substitute 42 for x in the equation that was created for susie
2x + 24 would now by (2*42) + 24 which is $108
So, the amount that bob has is $42 and susie has $108
You can double check your work by adding $42 and $108 together to see if you get $150 (which you do)

Which expression is equilvalent to (5g-2h)-(3h+8-4g).
Answer:
9g -5h - 8
