Answer:
Step-by-step explanation:
To find the x-intercept, substitute 0 for y and solve for x:
Divide both sides by 2:
Add 7 to both sides to isolate x:
The x-intercept for 
is 7 at point 
.
Remove parentheses:
Subtract 2 from both sides:
The x-intercept for 
is -2 at point 
.

Y=mx+b is the equasion of a line.
Answer:
x = -2
y = 1
Step-by-step explanation:
x−2y=6
<em>Multiply both sides by 2</em>
x-4y=12
<em>Subtract x from both sides</em>
-4y=12-x
2x−4y=10
<em>Subtract 2x from both sides</em>
-4y=10-2x
Put the 2 equations together:
12-x=10-2x
<em>Add x to both sides</em>
12=10-x
<em>Subtract 10 from both sides</em>
2= -x
<em>Multiply both sides by -1</em>
x= -2
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
Put the 2 equations together:
12+2y=10+4y
<em>Subtract 10 from both sides</em>
2+2y=4y
<em>Subtract 2y from both sides</em>
2=2y
y=1
Answer:
1.) scatter plot is attached below.
There is no sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals.
Step-by-step explanation:
Given the data :
Overhead width : 7.2 7.5 9.7 9.3 8.7 8.2
Weight : 119 156 243 200 199 188
The linear correlation Coefficient, R = 0.946
Using the Pvalue calculator for R score ;
Pvalue = 0.0149
Since, Pvalue > Α ; WE fail to reject the Null and conclude that there is no sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals.
Answer:
406.98 cm^3
Step-by-step explanation:
volume of the pack = 4.3 * 21 * 21 = 1896.3 cm^3
volume of a cylinder = π * r^2 * h
radius = 3.5/2 = 1.75
π * 1.75^2 * 4.3 = 41.37 cm^3
41.37 * 36 = 1489.32
1896.3 - 1489.32 = 406.98 cm^3
