4(x - 3) + 5 = 1....distribute thru the parenthesis
4x - 12 + 5 = 1....simplify
4x - 7 = 1...add 7 to both sides
4x = 1 + 7...simplify
4x = 8...divide both sides by 4
x = 8/4
x = 2 <===
Hello!
You first have to look and see if there is an outlier
An outlier is something that is away from the rest of the data
All the numbers are with 1 from each other so there is no outliers
The answer is the first one
Hope this helps!
Answer:
5
Step-by-step explanation:
in similar figures the side lengths must be proportional:
4/8 = x/10 cross multiply fractions
40 = 8x divide both sides by 8
5 = x
Answer:
y=2x+5
Step-by-step explanation:
To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)
So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2
Slope = 2, now find b
So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5
Put it all together y = 2x + 5
