Step-by-step explanation:
-3y=12+3x
-y=4+x
y=-4-x and m which is the gradient is the coefficient of x which is -1, therefore m=-1
Step-by-step explanation:
![\frac{y_2-y_1}{x_2-x_1}=\frac{15-(-13)}{28-(-28)}\\=\frac{28}{2(28)}\\\therefore\ m=\frac{1}{2}\\\frac{y-y_1}{xl-x_1}=m]\\\frac{y+13}{x+28}=\frac{1}{2}\\2y+26=x+28\\2y=x+2\\ y=\frac{1}{2}x+1](https://tex.z-dn.net/?f=%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B15-%28-13%29%7D%7B28-%28-28%29%7D%5C%5C%3D%5Cfrac%7B28%7D%7B2%2828%29%7D%5C%5C%5Ctherefore%5C%20m%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C%5Cfrac%7By-y_1%7D%7Bxl-x_1%7D%3Dm%5D%5C%5C%5Cfrac%7By%2B13%7D%7Bx%2B28%7D%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C2y%2B26%3Dx%2B28%5C%5C2y%3Dx%2B2%5C%5C%20y%3D%5Cfrac%7B1%7D%7B2%7Dx%2B1)
In order to find y for point C on AB, substitute point C in line equation if AB.
Answer:
if its an arc and center angle is given it could be double the size. IF it is a triangle measure you would use Pythagoras for triangle and trig for given angle, if two triangles are shown and they are scale of each other alternative measures given divide into each measure by the correct line and check this with the matching angles. when found as a division this is the ratio so then you just multiply to find the larger measure but divide to find the smaller measure. AC could also be a junction or vector, if its a type of vector then you just follow the arrows and count how many arrows fit the line pick a direction and ie) if its x2 a then you show a+a.

Answer: x = 0 y = –3
Step-by-step explanation:
We can solve this system by substitution.
use the second equation as a value for x.
Then substitute that value in place of x in the first equation and solve for y.
6x - 5y = 15 becomes
6(y + 3) - 5y = 15 Distribute 6 × parentheses
6y + 18 - 5y = 15 combine like terms
6y -5y + 18 = 15
y + 18 = 15 Subtract 18 from both sides.
y =15 -18
y = –3
Use this value for y in either equation to solve for x
6x - 5(-3) = 15
6x + 15 = 15 Subtract 15 from both sides, divide by 6 (seems silly!)
x = 0
OR in he second equation,
x = -3 + 3
Again, x = 0
Answer:
192 cakes. This is because the average cakes per minute is 4.8, you the multiply 4.8 by 40 to get 192.
