The equation in the slope-intercept form is:
y = (1/2)*x + 3
<h3>
How to write the equation?</h3>
A general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
To get the slope, we need two points on the line, by using the graph we can identify the points: (0, 3) and (2,4)
Then the slope is:
And we also can see that the y-intercept is y = 3, because of the point (0,3)
Then the line is:
y = (1/2)*x + 3

Answer:
7. Answer is 1236.25$
8. Answer is 143.75$
9. Answer is 16.485$
10. Answer is 6.825$
11. Answer is 31.25%
12. Answer is 0.125 for the decimal section and 12.5% for the percent section.
Step-by-step explanation:
7. 7.5 percent of 1150 is 86.25 and 86.25 + 1150 is 1236.25.
8. 15 percent of 125 is 18.75 therefore 125 + 18.75 is equal to 143.75.
9. 3.50 + 2.25 + 9.95 + 15.7 and 5 percent of 15.7 is 0.785 and 15.7 + 0.785 is 16.485.
10. 4.25 plus 2.25 is 6.50 and 5% of 6.50 is 0.325 and 6.50 plus 3.25 is 6.825.
11. 63 plus 25 is 88 so 88 is 68.75 percent of 128 and 100 minus 68.75 is 31.25 so 31.25 is the answer.
12. 1/8 is 12.5 percent so for the percent section it is 12.5 and for the decimal section 0.125
Answer:
8 units
Step-by-step explanation:
Since S is the midpoint of RT,
RS+ ST= RT
RS= ST
2RS= RT
Substituting the given information,
2(2x +4)= 8x
Expand:
2(2x) +2(4)= 8x
4x +8= 8x
Bringing x terms to one side of the equation:
8x -4x= 8
Simplify:
4x= 8
Divide both sides by 4:
x= 8 ÷4
x= 2
ST
= RS
= 2x +4
= 2(2) +4
= 4 +4
= 8 units
