10. The constant of proportionality would be 0.07 because in the equation y=kx 0.07 is substituted for k which stands for the constant of proportionality.
11. The equation is t=45d because for every hour you travel 45 miles (or 90/2, 135/3, etc.)
Answer: 100
Step-by-step explanation: I don't really have a step-by-step explaination, but I do know that the answer is 100.
Answer:
the answer is 1.4809 because you count 4 numbers after the decimal place and the fifth number influences the fourth. remember, if its 4 or below you round down and if its 5 or higher you round up.
Answer:
127 more posters than books.
Step-by-step explanation:
185-58=127
The resulting equation on using the completing the square is y = (x+5)² - 25
<h3>Completing the square method</h3>
The quadratic equation has a leading degree of 2. Given the equation below;
y = x^2+10x
Add the square of the half of coefficient of x to have;
y = x^2+10x + (10/2)²- (10/2)²
y = x^2 + 10x + 5² - 5²
y = x^2 + 10x + 25 - 25
y = (x+5)² - 25
Hence the resulting equation on using the completing the square is y = (x+5)² - 25
