Answer:
Total cost = $111
Step-by-step explanation:
Given:
Total number of oak tree = 3
Total number of elm tree = 1
Each oak tree cost = $23
Each elm tree cost = $42
Find:
Total cost
Computation:
Total cost = 3[Each oak tree cost] + 1[Each elm tree cost]
Total cost = 3[23] + 1[42]
Total cost = 69 + 42
Total cost = $111
Answer:
(c) or 10 is the answer
Step-by-step explanation:
In order to find slope you have to follow the formula
(y2-y1) / (x2-x1)
That would give you the slope which in this case is 10.
- It will be option A.
- x - coordinate is 1. If we multiply 3 with 1, it will be 3. And if we multiply 3 with 3, it will be 9.
- y- coordinate is 1. If we add 3 with 1, it will be 4. And adding 3 with 4, we get 7.
<u>Answer:</u>
<u>a- (1,1) (3,4) (9,7)</u>
Hope you could get an idea from here.
Doubt clarification - use comment section.
You have a line:
y=mx+b (slope-intercepted form)
m=slope of this line.
The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.
For example:
y=8x+3
m=8
The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
