Original points:
X (4,5)
Y (5,3)
Z (1,3)

When a point is reflected over the x-axis, its original coordinate (x,y) becomes (x,-y)

When a point is reflected over the y-axis, its original coordinate (x,y) becomes (-x,y)

I am assuming the triangle is reflected over the x-axis. But we have to consider that the line y = 1.

Point X (4,5) 

all things held constant, x' would have the coordinates (4,-5)

but line y = 1. So, x' (4, -3)

5 - 1 = 4 
1 - 4 = -3

There are 12 coins ; dimes and quarters. The number of dimes is 2 more than the number of quarters.
galben [10]

Answer:

D.  $1.95

F.  $3

Step-by-step explanation:

dimes:  x + 2

quarters:  x

x + 2 + x = 12

2x + 2 = 12

2x = 10

x = 5

dimes:  x + 2 = 5 + 2 = 7

quarters:  x = 5

Total value: (7 * .10) + (5 * .25) = $1.95

_____

dimes:  x

quarters:  2x

x + 2x = 15

3x = 15

x = 5

dimes:  x = 5

quarters:  2x = 2(5) = 10

Total value: (5 * .10) + (10 * .25) = $3

Evaluate.<br><br> [42 ÷ (2 + 3 • 2)] + [4 • (36 – 52)]<br><br> I really need help!!!
juin [17]
Ok so first we do 2 + 3 = 5 * 2 = 10 / by 42 = 4.2

other side 36 - 52 = 16 * 4 = 64 now add     4.2 + 64 = 68.2

Find the product and sum of the roots of the equation: 3x^2-10=0
cluponka [151]

● 3x^2 - 10 = 0

Add 10 to both sides

● 3x^2 - 10 + 10 = 10

● 3x^2 = 10

Divide both sides by 3

● 3x^2/3 = 10/3

● x^2 = 10/3

● x = √( 10/3 ) or x = - √( 10/3 )

● √(10/3) + (-√(10/3)) = 0

● √(10/3) × -√(10/3) = -10/3
