Answer:
Step-by-step explanation:Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).
Step 1: Find the slope of the line.
To find the slope of the line passing through these two points we need to use the slope
formula:
( )
( )
So the slope of the slope of the line passing through these two points is 3.
Step 2: Use the slope to find the y-intercept.
Now that we know the slope of the line is 3 we can plug the slope into the equation and
we get:
y = 3x + b
Next choose one of the two point to plug in for the values of x and y. It does not matter
which one of the two points you choose because you should get the same answer in either
case. I generally just choose the first point listed so I don’t have to worry about which
one I should choose.
(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.
–2 = –3 + b Solve for b and you will have the y-intercept.
b = 1
Answer:
1 1/10
Step-by-step explanation:
44/40
How many times can 40 fit evenly into 44? 1
So 44 - 40 (the 1) = 4
There are 4 remaining which will be the numerator.
The denominator stays the same: 40.
Your answer should look like: 1 4/40
Now simplify: 1 1/10
<span>A polygon is a closed figure made by joining line segments, where each line segment intersect exactry two other line segments.
A polygon is said to be a regular polygon if the sides are all of the same length.
Thus, the figures that are polygon are:
</span><span>Figure A which has 6 sides all made of line segments.
Figure B which is a regular hexagon, having 6 sides made all of segments.
</span><span>Figure D has 7 sides which are all segments.</span>
Answer:
For X = 11, the expression is equal to 31
Step-by-step explanation:
Hello
For X = 11 you only have to replaced the value into the expression, so:
3(11) + 4(11-8) - 14
33 + 4(3) - 14
33 + 12 - 14
31
Best regards
5(3x+4y) is equivalent to 15x-20 !
