Answer: 3x-4y+7=3y+1
Step-by-step explanation:
Since there is no negative x positive 4 and no negative number up to 7 that is the same, and since there is no negative number up to 3y or negative 1 the number stays the same so the answer is 3x-4y+7=3y+1
Answer:
a = 1/2 (b) (h)
Step-by-step explanation:
Use Pythagorean theorem for sub triangle on the left: 8^2 + h^2 = 22^2
Use Pythagorean again for sub triangle on the right: x^2 + h^2= 31^2
Find your base: 8+x=b
Find entire area: a = 1/2 (b) (h)
Angles on a straight line add up to 180 so take 91 away from 180 to give you 89 i guess ^^; i hope that helps somewhat
Answer:
y = -2x + 4
Step-by-step explanation:
Slope: (4-2)/5-1) = 2/4 = 1/2
Slope of the perpendicular line: -2
y-intercept: 2 - (-2)(1) = 4
