A negative number divided by a positive number yeilds a negative result
the rule is
if you divide or multiply 2 numbers with different sign (positive or negative), the result is negative
if you divide or multiply 2 numbers with the same sign (+ + or - - ), the result is positive
-42/8=-1 times 42/8=-1 times 21/4=--1 times 5 and 1/4=-5 and 1/4
Answer:
ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
<span> the volume of a sphere can be solve using the following formula:
</span>volume = 4/3 π r∧3
Given: r = 9yards
volume = 4/3 π r³
= 4/3 (3.14) 9³
= 4/3 (3.14) 729
= 4/3 (2289.06)
=9156.24/3
= 3052.08 yard³
<span> =3,052.1 yard³
</span>the volume of a sphere with radius 9 yd then is letter B. 3,052.1 yard³
Answer:
y = x/2 + 1
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Write equation
x - 4 = 2(y - 3)
Step 2: Solve for slope-intercept form
- Distribute 2: x - 4 = 2y - 6
- Add 6 to both sides: x + 2 = 2y
- Divide both sides by 2: x/2 + 1 = y
- Rewrite: y = x/2 + 1
