Find the solution set to this inequality:
[tex]2x - 3 > \frac{2x - 5}{2} [/tex]
a, b, c, or d
Answer:
c
Step-by-step explanation:
2x-3 > 2x-5/2
⇒2x-3/1=2x-5/2
⇒(2x-3)×2=(2x-5)×1
4x-6=2x-5
⇒2x-1>0
⇒2x>1
⇒x>1/2
Answer:
[tex]2x - 3 > \frac{2x - 5}{2} \\ 2(2x - 3) > 2x - 5 \\ 4x - 6 > 2x - 5 \\ 4x - 2x > 6 - 5 \\ 2x >1 \\ \boxed{x > \frac{1}{2} }[/tex]

7 Tacos and 3 burritos cost $22
3 tacos and 1 burrito cost $8
Define x and y:
Write a system (2) equations to model the
situation:
What is the cost of a taco? What is the cost of
a burrito?
Answer:
System of Equations:
let x be the cost of a taco
let y be the cost of a burrito
7x + 3y = 22
3x + y = 8
The cost of a taco is $1
The cost of a burrito is $5
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answers:
Equations: 7x+3y=22
3x+y=8
The cost of tacos is $1 and the cost of burrito is $ 5.
Step-by-step explanation:
Let the cost of tacos be x and the cost of burrito be y.
Equations: 7x+3y=22
3x+y=8
3x+y=8, y=8-3x
sub y=8-3x into 7x+3y=22, 7x+3(8-3x)=22
-2x=-2
x=1
sub x=1 into 3x+y=8, 3(1)+y=8
y=5
∴The cost of tacos is $1 and the cost of burrito is $5.

Answer: x = 8
MN = 52
LK is congruent to LM
LN is congruent to NL
ΔKLN and ΔMLN have:
LN ≅ LN
∠K = ∠M = 90°
∠KLN = ∠MLN
=> ΔKLN ≅ ΔMLN
=> KN = MN
=> 7x -4 = 5x + 12
⇔ 2x = 16
⇔ x = 8
=> KN = MN = 7.8 - 4 = 52

P, Q, and R form the vertices of a triangle. QR = 7.8 RP = 15.7 and PQ = 11.6 Find the angle PRQ rounded to 1 DP
Answer:
45.1°
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Cosine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:
[tex]a^2=b^2+c^2-2bc*cosA\\[/tex]
Given triangle PQR, let ∠PQR = x, to find angle PQR, we use cosine rule:
[tex]PQ^2=QR^2+RP^2-2(QR)(RP)*cos(x)\\\\substituting:\\\\11.6^2=7.8^2+15.7^2-2(7.8)(15.7)cos(x)\\\\134.56=60.84+246.48-244.92cos(x)\\\\244.92cos(x)=60.84+246.48-134.56\\\\244.92cos(x)=172.76\\\\cos(x)=0.7054\\\\x=cos^{-1}(0.7054)\\\\x=45.1^o[/tex]
x = ∠PQR = 45.1°

Answer:
Not a triangle
Step-by-step explanation:
In order for a shape to qualify as a triangle, the interior angles must add up to 180°
These angles only add up to 56°, therefore it is not a triangle.
Answer:
obtuse
Step-by-step explanation:
You have an isosceles triangle. 2 of the sides are equal in length. Since, the third side is longer than than the other 2, it will form an obtuse angle. If the third side was shorter, you would have all acute angles.

Answer:

What is Composition of functions?
Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the equation for the function f ( x ) = x + 3
Let the equation for function g ( x ) = 2x² + 3
Now , the composition of function is calculated by
( f . g ) ( x ) = f ( x ) . g ( x )
So , the equation for the new composed function will be
( f . g ) ( x ) = ( x + 3 ) ( 2x² + 3 )
= 2x³ + 6x² - 4x - 12
Therefore , the value of ( f . g ) ( x ) is 2x³ + 6x² - 4x - 12
Hence , the composition function ( f . g ) ( x ) is 2x³ + 6x² - 4x - 12
