Answer:
(1 , 2) and (3 , 6)
Step-by-step explanation:
the point P : (x , y) -> (x , 2x) ... ordinate of P point is twice its abscissa, y = 2x
√10 = √(x-4)² + (2x-3)²
5x² - 20x + 25 = 10
x² - 4x + 3 = 0
(x-1)(x-3) = 0
x = 1 or x = 3
y = 2 or y = 6
Which lines are parallel to y = -4x + 7?
A y-1=4(x+8)
B y=-4x+15
C 16x+4y=9
D y=-4x

Mike and Lilly are working together on a science project. They agreed to
meet halfway between their houses and ride their bikes to the library
together. Approximately how far will Mike and Lilly ride to the library once
they meet each other at the halfway point?
The approximate distance Mike and Lilly will have to travel between halfway point and Library is 7.8 miles.
From the graph :
Mike's coordinate = (-4, 2) Lilly's coordinate = (2, - 2) Library coordinate = (4, 6)Meeting point = Halfway point :
(x1 + x2) /2 ; (y1 + y2) / 2
X - coordinate = (-4 + 2) / 2 = - 2/ 2 = - 1
Y - coordinate = (2 + (-2)) /2 = 0/2 = 0
Hence, meeting point = (-1, 0)
The distance between meeting point and library :
Distance = √[(x2 - x1)² + (y2 - y1)²]
Distance = √[(4 - (-1))² + (6 - 0)²]
Distance = √(25 + 36)
Distance = √61 = 7.8 miles
Therefore, the distance between halfway point and library ls approximately 7.8 miles

Drag expressions to show the steps to create an equivalent expression using only positive exponents. Let g and h be two nonzero numbers. g^-3h
Equivalent expressions are expressions that have the same value.
The equivalent expression of [tex]g^{-3}h[/tex] is: [tex]\frac{h}{g^3}[/tex]
The expression is given as;
[tex]g^{-3}h[/tex]
Apply law of indices to change the exponents
[tex]g^{-3}h = \frac{1}{g^3}h[/tex]
Express as products
[tex]g^{-3}h = \frac{1}{g^3} \times h[/tex]
Rewrite as
[tex]g^{-3}h = \frac{h}{g^3}[/tex]
Hence, the equivalent expression is: [tex]\frac{h}{g^3}[/tex]

5x - 4y = 19
x + 2y = 8
Answer:
x= 5 and y = 1.5
Step-by-step explanation:
5x -4y = 19
x + 2y = 8
let x = 8 - 2y...
5x - 4y = 19.......x = 8 -2y
5(8-2y) - 4y = 19
40 - 10y -4y= 19
40-14y = 19
-14y = 19-40
-14y = -21
y = 1.5
x = 8 - 2(1.5)
x = 8 - 3
x = 5
Thus, x is 5 and y is 1.5

Find the measure of each angle indicated
A) 21°
C) 23°
E) 25°
B) 80°
D) 20°
Answer:
D
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ADE is an exterior angle of the triangle , then
80° + ? = 100° ( subtract 80° from both sides )
? = 20° → D

Find the value of x and then find EF if E is the midpoint of line segment DF.
DE = 15 - 3x
EF = x + 3
Answer:
EF=6
Step-by-step explanation:
E is the midpoint, so DE = EF
DE = 15-3x
EF = x+ 3
Since DE = EF,
15 - 3x = x + 3
-4x = -12
x = 3
If x = 3,
DE = 15 - 3*3, 15 - 9 = 6
EF = x+ 3, so EF = 3 + 3 = 6
