Answer:
y = 1/2x
Step-by-step explanation:
x - 2y = -4
x = -4 + 2y
x + 4 = 2y
2y = x + 4
y = 1/2x + 2
y = 1/2x
The area formula for rectangles is lxw. To solve, I would divide the figure up into 3 rectangles- top,middle and bottom, then find the areas and add them together.
Top: 4x13=52 cm^2
Middle: 5x8=40 cm^2
Bottom: 21x10=210 cm^2
(5 is the width of the middle piece. You get it from subtracting. 21-8-8=5. 13 is the width of the top piece. 5+8=13)
52+40+210
=302 cm^2
So your answer is 302 square centimetres.
9,000,000,000 + 3,000,000 + 800,000 + 40,000 + 100 + 60 + 5. Give brainliest please.
Answer:
y=−x/2+2.
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=2x−5.
The slope of the perpendicular line is negative inverse: m=−12.
So, the equation of the perpendicular line is y=−x/2+a.
To find a, we use the fact that the line should pass through the given point: 3=(−12)⋅(−2)+a.
Thus, a=2.
Therefore, the equation of the line is y=−x/2+2.
