The friend is incorrect because 2 translations would just move the shape to a different area, then a reflection would reflect it.

Long story short: if you do to translations that only move in one direction for ex. X+10 y+ 0 then it will be a glide reflection

Explain how to use the order of operations to evaluate numeric expressions.

murzikaleks [220]

U will use the pemdas method which is if u check parentheses, exponents, multiplication, division, addition, subtraction. for ex. say the expression is 5 + 30+ (5x10) u will check if u have any p, e, m, d, a, or s and do those steps in order. sometimes u will read left to right if it’s a divison first and then a multiplication

Two sides of a triangle measure 9 cm and 23 cm what could be the measurement of the third side of the triangle

Vladimir79 [104]

Pythagorean Theorem: a^2+b^2=c^2
(9)^2 + b^2 = (23)^2
81 + b^2 = 529
b^2 = 529 - 81
b^2 = 448
b^2 =
$\sqrt{448}$
b = 21.2

Solve 7log9(x + 8) = 7

Bumek [7]

Remember
$log_a(b)=c$ translates to $a^c=b$

alrighty

so we've got
$7log_9(x+8)=7$
divide both sides by 7
$log_9(x+8)=1$
translate
$9^1=x+8$
9=x+8
minus 8 both sides
1=x
x=1
