Y = 4x - 7 is a line with a slope of 4 and y-intercept of -7.
plug in any X value, for example 1 and you get the following
y = 4(1) - 7
y = -3
(1,-3) is a point that satisfies the equation y = 4x - 7

The formula for the area of a circle is pi(3.14) * r(4)^2
Hope it helps <3 :D
for the first one $5.34 ÷ 6 so if u type that into a calculate it will say $0.89
Hi!
So this is an algebra question. We basically want to know what number minus 2 and 1/2 is going to equal 7 and 1/2. An easy way to check for that first number is adding those two numbers together
So we take 2 and 1/2 + 7 and 1/2 , and because they have the same denominator we can add the two numbers . 2 + 7 = 9 and then 1/2 + 1/2 = 1 so 9+ 1 = 10
10- 2 1/2 = 7 1/2
First you multiply the two equations, equaling 3000000 kg and 60000 kg respectively. Once you have those numbers, you divide the Oakland mass by the Mapleville mass, so 3000000/60000. The answer is 50, to the tree is B, 50 times as big.
