The answer is 90.
28/2.8 = 10
10 x 9 = 90
Answer:
equation: 6x = -105
answer: x = -17.5
Step-by-step explanation:
the product of 6 and a number (6x) is the same (=) as -105 (-105)
6x = -105
/6 /6
x = -17.5
Y = 4x - 1
// Plug this in for variable y in equation [1]
[1] 20x - 5•(4x-1) = 5
[1] 0 = 0 => Infinitely many solutions
Both together cost $1759.
That means that sum of the two prices is $1759.
The operation that is the opposite of addition is subtraction.
We subtract $469 from $1759 to find the price of the televition.
$1759 - $469 =
1759
- 469
-----------
1290
$1759 - $469 = $1290
Answer: The price of the television is $1290.
y = - 
x - 34
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 68, 0 ) and (x₂, y₂ ) = (0, - 34 )
m = 
= 
= -
the y-intercept = (0, - 34 ) ⇒ c = - 34
y= - x - 34
