Answer: Required system
x+y= 30
0.25x+0.05y=5.10
Jude has 18 quarters and 12 nickels.
Step-by-step explanation:
Let x= Number of quarters
y= Number of nickels
As per given,
x+y= 30 (i)
0.25x+0.05y=5.10 (ii) [1 quarter = $0.25 , 1 nickel = $0.05]
Multiply 0.25 on both sides of equation (i)
0.25x+0.25y= 7.5 (iii)
Eliminate (ii) from (iii) , we get
0.20y=2.4
⇒ y = 12 [divide both sides by 0.20]
Put value of y in (i\), we get
x+12=30
⇒ x= 30-12= 18
Hence, Jude has 18 quarters and 12 nickels.

Drag the correct description to tell whether the graph represents a function.
Answer:
1) Not a function 2) function 3) function
Step-by-step explanation:
Use the vertical line test. If you draw a line on every vertical line on the graph and you see two points, it is not a function.
The graph is shown in options B) and C) represents a function and this can be determined by carefully observing the given graph.
Check all the options in order to determine whether the graph represents a function or not.
A) The graph shows in this option that the two lines are intersecting at (x = 2). Therefore, this graph does not represent a function.
B) The graph shows in this option is in the shape of a parabola whose vertex is at (-2,0). Therefore, this graph does represent a function.
C) The graph shows in this option is in the shape of a wave. This graph may represent a trigonometric function. Therefore, this graph does represent a function.

Put 2y= -3x = 5 in standered form
Answer:
3x + 2y = 5
Step-by-step explanation:
Given: 2y= -3x + 5 (assuming the sign before 5 is + instead of =)
for standard form, it has to be in ax + by = c
2y = -3x + 5; add 3x to both sides
3x + 2y = 5
Captain America's circular shield has a diameter of 76.2 centimetres. What is the area of his shield?
Answer:
4560.37
Step-by-step explanation:
A= 1 /4 x π x 76.2²
Brainliest?????
The area of the Captain America's circular shield is 4560.36 cm²
From the question,
We are to determine the area of Captain America's circular shield, which has a diameter of 76.2 cm.
To do this,
We will use the formula for finding the area of a circle.
The formula for the finding the area of a circle is
[tex]A = \pi r^{2}[/tex]
Where, A is the area
and r is the radius of the circle
From the question
Diameter of the circular shield = 76.2 cm
First, we will determine the radius of the circular shield
From
[tex]Radius = \frac{Diameter}{2}[/tex]
∴ Radius of the circular shield = [tex]\frac{76.2}{2}[/tex] cm
Radius of the circular shield = 38.1 cm
Now, for the area of the shield
r = 38.1cm
∴ Area of the shield = [tex]\pi \times 38.1^{2}[/tex]
Area of the shield = 1451.61π
(Take π = 3.14159)
∴ Area of the shield = 1451.61 × 3.14159
Area of the shield = 4560.36 cm²
Hence, the area of the circular shield is 4560.36 cm²

Answer:
Let ΔABC and ΔDEF be two triangles such that ∠A = ∠D and ∠B = ∠E.
∠A + ∠B + ∠C = 180 0 (Sum of all angles in a Δ is 180)
∠D + ∠E + ∠F = 180 0 (Sum of all angles in a Δ is 180)
⇒ ∠A + ∠B + ∠C = ∠D + ∠E + ∠F
⇒ ∠D + ∠E + ∠C = ∠D + ∠E + ∠F (since ∠A = ∠D and ∠B = ∠E)
⇒ ∠C = ∠F
Thus the two triangles are equiangular and hence they are similar by AA.

Which of the following statements are true for this function? Select all that apply.
A. The function is discontinuous at x=-1
B.The function is discontinuous at x=1
C. The value of the function is never negative
D. x=1 is not the domain of the function
E. The value of the function at x=-1 is 0
F. The value of the function at x=1 is 0
Answer:
A, C, and E
Step-by-step explanation:
Given is a graph of a function first a straight line, followed by a semi circle centred at the origin and another piece of straight line not connected to the other graph.
We can see that the funciton is discontinuous at x=1 since
right limit = 1 and left limit =0
x=1 is in the domain .
f(-1) =0 is right
But f(1) =0 is incorrect
Thus correct options are
The function is discontinuous at x = 1.
The value of the function is never negative.
The value of the function at x = -1 is 0
