The isoscelecs triangle below has a perimeter of 6x+7 if the base is 5 what is the length of each of the unknown sides

1. 22

2. 1

3. 7

4. 18

step-by-step explanation

e2020 got it right

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
