Answer:
Equation of the line; y=x+3
Step-by-step explanation:
Graph the line that passes through the points (5,8) and (3,6) and determine the equation of the line.
Equation of a line: y=mx +b
Let's find the slope:
8-6/ 5-3= 2/2 = 1
y=x+b
Substitute the points in.
y= 8
x = 5
8 = 5+b
b= 3
The y-intercept is 3.
y=x+3
Points on the line: (-2,1) (-1,2) (0,3) (1,4) (2,5)

Answer:
At 5% amount invested = $7,500
At 7% amount invested = $3,500
Step-by-step explanation:
We shall create an equation for this.
Let the amount invested with 5 % interest = "x"
Then remaining amount = 11,000 - x, Since total amount invested = $11,000
(x 5%) + ((11,000-x)
7%) = $620
0.05 x + 770 - 0.07 x = 620
770 - 620 = 0.07 x - 0.05 x
150 = 0.02 x
= x
$7,500 = x
Therefore, amount invested at 5% = $7,500
At 7% = $11,000 - $7,500 = $3,500
Answer:
38cm
Step-by-step explanation:
1. The perimeter of a square can be found with the formula
2. Since its length and width are whole numbers, it must be either
1 x 18,
2 x 9 or
3 x 6
3. Using the formula in step 1, we can found that the perimeter in these cases are
38
22
18
respectively
4. Compare those perimeter we found in previous step, it's obvious that the greatest is 38. Solved.
Answer:
is neither significantly low nor significantly high.
Step-by-step explanation:
From the information given, we know that:
The mean is and the standard deviation is
.
The range rule of thumb says that:
Applying these definitions, we get that
We note that is between
and
, which indicates
is neither significantly low nor significantly high.
