Answer:
y= -x+5
Step-by-step explanation:
→first you need to identify 2 points. I'm using (5,0) and (0,5)
→second you need to find the slope using y2-y1/x2-x1 as your formula
5-0/0-5= 5/-5=-1
→then you need to use y-y1=m(x-x1) formula
y-0=-1(x-5)
(distribute the -1)
y-0= -1x+5 (+5 because a negative times a negative is a positive)
(combine like terms)
y= -1x+5
→once you solve you get y= -x+5
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.
Answer:
x = 1°
Step-by-step explanation:
Bisection means splitting the angle in to 2
So that means 4x-1 = 2x+1
4x-1 = 2x +1
4x = 2x + 2
2x = 2
x = 1°

Answer:
4 - 4x³ + 20x² - 20x
Step-by-step explanation:
(g × f)(x) = g(x) × f(x) = (x³ + 5x)(4x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x³(4x - 4) + 5x(4x - 4) ← distribute both parenthesis
= 4 - 4x³ + 20x² - 20x
This can also be done using FOIL, that is
(x³ + 5x)(4x - 4)
= 4 - 4x³ + 20x² - 20x
<h2>Answer:</h2>
m<1=130°[alternate angle are equal again]
m<1+m<2180°[linear pair]
m<2=180°-130°
