Answer:
Step-by-step explanation:
Remark
The relationship that solves this is
The outside segment * the whole length of the secant = the outside segment of the other secant * the whole length of the second secant.
Put in symbolic (and hence easier language)
GF * EG = HG * SG
Givens
GF = 4
EG = 2x + 4
GH = 5
SG = x + 5
Equation
4*(2x + 4) = 5*(x + 5) Remove the brackets
8x + 16 = 5x + 25 Subtract 5x from both sides
8x - 5x + 16 = 25 Combine
3x + 16 = 25 Subtract 16 from both sides
3x = 25 - 16
3x = 9 Divide by 3
3x/3 = 9/3
x = 3
EF = 2 * 3
EF = 6
Answer:
False
Step-by-step explanation:
That is false
If the pre-image is reflected over any axis, the image will still be congruent to it
Just multiply it and you will get your answer
Answer:
Step-by-step explanation:
Grace paid $4.80/(4 notebooks) = {$4.80/4)/notebook = $1.20 per notebook
Jim paid $3.90/(3 notebooks) = ($3.90/3)/notebook = $1.30 per notebook
Grace found the better buy.
I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
