Step-by-step explanation:
Answer: y = 2/3x + 41/3
Step-by-step explanation:
First convert the equation into slope-intercept
3x + 6y = 4y - 4
-4y -4y
3x + 2y = -4
-3x -3x
2y = -3x - 4
y = -3/2x - 2
Perpendicular lines have a negative reciprocal for their slopes.
The negative reciprocal of -3/2 is 2/3
Now using the slope 2/3 you will use the formula y =mx +b and input the slope, and the x and y coordinates of the given point, (-10,7), to solve for the y-intercept.
7 = 2/3(-10) + b
7 = -20/ 3 + b
+ 20/3 + 20/3
b = 20/3 + 21/3 = 41/3
Since the the y-intercept is 41/3 then the equation will be , y = 2/3x + 41/3
Answer:
a.) 61 square feet
b.) $152.50
Step-by-step explanation:
first you find the area for the rectangle
LxW=A
10x4=40
then you find the area for the triangle
(bxh)1/2=a
(6x7)1/2=21
-we get 7 from adding the height that we know (3ft) and using logic, a rectangle has equal parallel lines so the dotted line has to equal 4ft. so 3ft+4ft=7ft
then you add both areas together
40 square feet+21 square feet= 61 square feet
<em>Now</em><em> </em><em>for</em><em> </em><em>B</em><em>.</em><em>)</em>
as we know, the area of the room floor is 61sq feet. so by multiplying 2.5 and 61 you get the cost as $152.50
Answer:
x₍ₙ₎ = x₍₁₎ * (-5)ⁿ⁻¹
Step-by-step explanation:
x₍ₙ₎ = x₍₁₎ * (-5)ⁿ⁻¹
x₍₁₎ = -2
x₍₂₎ = (-2) x (-5)²⁻¹ = (-2) x (-5) = 10
x₍₃₎ = (-2) x (-5)³⁻¹ = (-2) x (-5)² = -50
You will have $5 left because if you spend 1.25 on 12 snacks you will spend $15
