Answer:
The correct answer is
Explanation:
We are given the points:
(0, 4)
(1, 5)
(2, 6)
(3, 7)
We can see that for each unit that x-coordinate grows, the y-coordinate also grows one.
This means that the slope of the line is m = 1
The first point given, tell us the y-intercept: (0, 4)
The slope-intercept form of a line is:
Where m is the slope and b the y-intercept.
For the points given:
m = 1
b = 4
Thus:
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex
In this problem we have
(h,k)=(1,-4)
substitute
we have
An x-intercept of (-1,0)
substitute and solve for a
The equation is
<u><em>Verify the y-intercept</em></u>
For x=0
The y-intercept is the point (0,-3) -----> is correct
using a graphing tool
see the attached figure
Simplify the following:
k - 2 (k - (2 - k)) - 2
-(2 - k) = k - 2:
k - 2 (k + k - 2) - 2
Grouping like terms, k + k - 2 = (k + k) - 2:
k - 2 ((k + k) - 2) - 2
k + k = 2 k:
k - 2 (2 k - 2) - 2
-2 (2 k - 2) = 4 - 4 k:
k + 4 - 4 k - 2
Grouping like terms, k - 4 k - 2 + 4 = (4 - 2) + (k - 4 k):
(4 - 2) + (k - 4 k)
k - 4 k = -3 k:
-3 k + (4 - 2)
4 - 2 = 2:
Answer: 2 - 3 k
Answer:
<h3>15%</h3>
Step-by-step explanation:
<h3>First , We will solve their daily Income </h3>
• Income = spends / rate
• Income = 600 / 40%
• Income = 600 / 0 .40%
• Income = 1500
Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .
• Rate = spent / Income
• Rate = 225 / 1500
• Rate = 0.15
• Rate = 15%
Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%
