Hope I helped. If so, may I get brainliest and a thanks?
Thank you. Have a good day! =)
Answer:
26÷2=13 so if the longer one is 2 cm longer so 13+1 =14. the shorter one is going to be 13-1=12 so 12+14 =26 and the shorter one is 2 cm smaller then the longer one
Answer:
Additive
-2 = 2
18 = -18
-30 = 30
2/5 = -2/5
Multiplicative
8/9 = 9/8
12/15 = 15/12
-6 = -1/6
10 = 1/10
Step-by-step explanation:
an<em> additive inverse</em> is a number you must add to another number to get 0
(think of it as the negative version of the number)
<em>{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}</em>
-2 + 2 = 0
18 - 18 = 0
-30 + 30 = 0
2/5 - 2/5 = 0
a <em>multiplicative inverse</em> is a number that you multiply by another number to get 1.
We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction
(reciprocal of 2 = 1/2 {remember, 2 is the same thing as 2/1 } ; reciprocal of 1 / 8 = 8)
<em>note: reciprocal is being used interchangeably with multiplicative inverse here</em>
<em />
8/9 · 9/8 = 1
12/15 · 15/12 = 1
-6 · -1/6 = 1 {-6 = -6/1}
10 · 1/10 = 1 {10 = 10/1}
hope this helps!! have a lovely day :)
Answer(C)
√(9x^2)= 3x
√(18y^2)=3y/√2= 3y/√2 X √2/√2
=3√2y/2
Lets get this into y-intercept form first, which is y =mx+b:
8(4+x)-3 = 12(x+y)+5
32+8x-3 = 12x+12y+5
-4x+24 = 12y
-1/3x+2 = y or y= -1/3x + 2
X intercept:
0 = -1/3x + 2
-2= -1/3x
6 = x
X intercept is (6,0)
Y intercept:
y = -1/3(0) + 2
y= 2
Y intercept is (0,2)
