Answer:
The percentage increase in Spencer’s height is 125 %
Solution:
Initial height of spencer = 28 inches
Increased height of spencer = 5 feet 3 inches
= 5 feet + 3 inches
(5 feet = 5 ×12=60 inches)
= 60 + 3
Answer: 
Step-by-step explanation:
Given: The number of days Jonathan ran = 5
The most he ran in 1 day = 3.5 miles
Therefore, the maximum distance he ran in a week= 
Let x be the distance Jonathan could have rum in a week, such that
Hence, the required inequality is .
Answer:
28/9
Step-by-step explanation:
If the roots are J and K, then:
3 (x − J) (x − K) = 0
3 (x² − (J+K)x + JK) = 0
So if we factor out the leading coefficient:
3x² − 2x − 4 = 0
3(x² − 2/3x − 4/3) = 0
The coefficient of the second term is the sum of the roots:
J + K = 2/3
And the constant is the product of the roots:
JK = -4/3
If we take the sum of the roots and square it:
(J + K)² = (2/3)²
J² + 2JK + K² = 4/9
And subtract twice the product:
J² + K² = 4/9 − 2JK
J² + K² = 4/9 − 2(-4/3)
J² + K² = 4/9 + 8/3
J² + k² = 28/9
Answer:
Step-by-step explanation:
<u>Slope intercept form:</u>
- y = mx + b, where m - slope, b - y-intercept
<u>Take two points from the graph:</u>
<u>Find the slope:</u>
- m = (3 - 1)/(3 - 1) = 2/1 = 2
<u>Find the y-intercept using point (2, 1) and the equation above:</u>
- 1 = 2*2 + b
- b = 1 - 4
- b = -3
<u>The line is:</u>
