<h3>
Answer: 15</h3>
=======================================================
Work Shown:
Replace every x with 2 and simplify
y = 7x+1
y = 7*2 + 1
y = 14 + 1
y = 15 is the y coordinate
The vertical line x = 2 meets the diagonal line y = 7x+1 at the location (x,y) = (1,15)
Yes they can be greater than one no they can't be grater than 2
Gianna paid less per necklace so she got the better deal
Gianna: 50.75 / 7 = 7.25
So she paid $7.25 per necklace
Winnie: 24.60 / 3 = 8.20
So she paid $8.20 per necklace
Visualize the image in your mind and you can see that it forms a right angled triangle with a base,altitude and hypotenuse
base=2 feet
hypotenuse(ladder)=13 ft
We need to find the altitude,
By applying pythagoras theorem,
base square+altitude square=hypotenuse square
Take altitude as x
2 square+x square=13 square
4+x square=169
x square=169-4
x square=165
x= root of 165
x=12.8 feet(approx.)
Answer:
B) B only
Step-by-step explanation:
An equilateral triangle is a triangle that has all equal sides. Triangle B is the only one that has equal sides.
