Answer:
y = -2x - 2
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -2
so now the equation is y = -2x + b
from here, what you could do to find b is...
plug (-2, 2) into the equation
1) x = -2, y = 2
2) 2 = -2(-2) + b
3) 2 = 4 + b
4) -2 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -2)
so "b" would be equal to -2
this makes the final equation y = -2x + (-2) or y = -2x - 2
Answer:
a = 5
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle
a² + 12² = 13²
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take the square root of both sides )
a =
= 5

Answer:
The original goal is $25019.154 .
Step by step Explanation:
Let us assume that the origianl goal be x .
As given
Another project on Kickstarter for an iPad stylus raised 1,253% of their goal, raising a total of $313,490 .
1253% is written in the decimal form .
![= \frac{1253}{100}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1253%7D%7B100%7D)
= 12.53
Than the equation becomes
12.53 × x = 313490
12.53x = 313490
![x = \frac{313490}{12.53}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B313490%7D%7B12.53%7D)
x = $ 25019.154
Therefore the original goal is $25019.154 .
