Answer:
(2,-6) and (4,-16)
Step-by-step explanation:
-5x+4 crosses these points
8x - 2x(x+1) = 2(3x-1)
First, expand to remove parenthesis. / Your problem should look like:
8x - 2x - 2 = 6x - 2
Second, subtract 8x - 2x -2 to get 6x - 2. / Your problem should look like:
6x - 2 = 6x - 2
Third, both sides are equal, so there are infinite solutions. The equation is always true, meaning identity
Answer: Infinite solutions

Answer:
k = 4 units
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
k² + 7.5² = 8.5²
k² + 56.25 = 72.25 ( subtract 56.25 from both sides )
k² = 16 ( take the square root of both sides )
k = 
= 4
X/8 - 10 = x/3
bring the values with the variable on one side
x/3 - x/8 = 10
find a common denominator and subtract these fractions
8x/24 - 3x/24 = -10
now subtract fractions
8x - 3x = 5x
5x/24 = -10
multiply both sides by 24
5x = -240
divide both sides by 5
x = -48
the number is -48
Answer:
A. 1200
Step-by-step explanation:
Speed in meter per minute
= (216*1000)/(3*60)
= 216000/180
= 1200
