14 - x = 21
First, subtract 14 from both sides. / Your problem should look like: -x = 21 - 14
Second, simplify 21 - 14 to get 7. / Your problem should look like: -x = 7
Third, multiply both sides by -1. / Your problem should look like: x = -7
Answer: x = -7
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
Answer:
C ) y = -2x
Step-by-step explanation:
(2, -4)
y = -2x
subsitute x for the value of x
y = -2(2)
-2 × 2 = -4
y = -4
so
the equation for the point (2, -4) is
y = -2x
Answer:
Step-by-step explanation:
(-4,-23) , (-2,-11)
slope = (-11 - (-23) / (-2 - (-4) = (-11 +23) / (-2 + 4) = 12/2 = 6
y = mx + b
slope(m) = 6
(-4,-23)...x = -4 and y = -23
now we sub and find b, the y int
-23 = 6(-4) + b
-23 = -24 + b
-23 + 24 = b
1 = b
so ur equation is : y = 6x + 1....with ur slope being 6 and ur y int being 1 or (0,1)
** just so you know, instead of working out the y= mx + b and finding ur y int, u could have just looked at ur points...ur y int is when x = 0...and u have a point (0,1)....meaning ur x is 0....making 1 ur y int.
