The formula: y = mx + b
m = slope or rise/run
b = y-intercept
So, the y-intercept would be -4 and the slope would be 2.
First, you would need to find the y-intercept, -4.
Next, you would use the slope, 2, to find the coordinate. Remember, 2 = 2/1
You would rise 2 and run 1.
The coordinates to form a line would be (1,-2), (3,2), and (-1,-6). All you would need to do is draw a line through the coordinates.
I hope this helps!
No. 4 squared is 16 and 16 + 79 is 85 not 88
Answer:
x=-3
Step-by-step explanation:
Answer:
small posters cost $2.30 each
large posters cost $4.95 each
Step-by-step explanation:
Let
price of large poster be "l", and
price of small poster be "s"
$16.80 for 2 large and 3 small, we can write:
2l + 3s = 16.80
Then,
$14.15 for 1 large and 4 small, we can write:
l + 4s = 14.15
We can write this as:
l = 14.15 - 4s
Now we substitute this expression for "l" into first equation and solve for s first:
small posters cost $2.30 each
Now, we know l = 14.15 - 4s, so
l = 14.15 -4(2.30)
l = 4.95
large posters cost $4.95 each
<span>c(ad)+x=bd+ad(yz)
step 1:
first we separate x and y , so
x=bd+adyz-cad
Note: i) (yz) can be written as yz
ii) when the term cad comes to right side it becomes -cad, because it is with the addition operation in the left hand side. (it is a general rule of mathematics)
step 2: then we take out the common data from the above equation, so the common term for all terms in the right hand side is 'd',
so, x=d(b+ayz-ca)
step 3: now we need to find d, so
d =x/b+ayz-ca
Note: the term (b+ayz-ca) becomes the divisor of x since it is in the multiplication term on right hand side. so when moving it to left side, it becomes a division operator. (it is also a general rule of mathematics)
so d =x/b+ayz-ca</span>
