The equation is y = -2/3x + 6
Answer:3.6
Step-by-step explanation:
Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
To find the vertex, you need to find the axis of symmetry first.
In order to find the axis of symmetry we have to do -b/2a.
In our case, the b is -8 and the a is 1.
Plug it in.
-(-8)/2(1)
8/2 = 4
Our axis of symmetry is 4.
Now, we plug it into the equation to find the rest of the vertex.
y = 4^2 - 8(4) + 1
y = 16 - 32 + 1
y = -16 + 1
y = -15
Put it together.
Our vertex is (4,-15).
Answer: LAST OPTION.
Step-by-step explanation:
To solve this exercise is important to remember the following definitions:
- The sum is the result obtained when we solve an addition.
- The product is the result obtained when we solve a mutiplication.
- Given a multiplication
, "a" and "b" are factors and "c" is the product.
In this case, you have this expression:
Notice that the there is an addition of two terms (
and 
) inside the parentheses.
Outside the parentheses you can notice that the number 
is multiplying the sum of the terms mentioned before.
Therefore, you can conclude that the best description for this expression is:
<em>The product of a constant factor of seven and a factor with the sum of two terms.</em>
