Answer:
k = - 6
Step-by-step explanation:
Given a function f(x), then a horizontal translation parallel to the x- axis is denoted by
f(x + k)
If k > 0 then shift of k units left
If k < 0 then shift of k units right
Here the shift is 6 units to the left, from 4 to - 2, hence
k = 6
Assuming that the triangle is a right triangle, we can reverse engineer the Pythagorean theorem (a^2+b^2=c^2).
60^2 + x^2 = 61^2
3600 + x^2 = 3721
x^2 = 3600 - 3721
x^2 = 121
x = sqrt121
x = 11
2)The goal is to isolate the variable and get is down to x<?. This is actually a two step inequality problem. 0.7x - 2 < 5.5 +2 +2 0.7x<7.5 This implies: x<10.714 The way to graph this is to place an open circle of the number 10.714 on the number line indicating this number is not included as a solution to the inequality. Then draw the arrow going left from the open circle indicating all numbers from -∞ to 10.714.
Expand (3x)^2
When you see ^2, it means that the term(s) inside the parenthesis should be copied once, and multiplied.
(3x)^2 = (3x)(3x)
(3x)(3x) is your expanded form
