To solve this problme you must apply the proccedure shown below:
1. To find the x-intercept y must be zero, so, you have:
<span>−75x − 4y = 7
y=0
</span><span>−75x=7
x=-7/75 (x-intercept)
2. To find the y-intecept x must be zero, then, yo have:
x=0
</span><span>−75x − 4y= 7
-4y=7
y=-7/4 (y-intercept)</span>
Ok so I did the math and I got 9,765,625. But I’m not totally sure about my answer
A proportion is a pair of equal ratios.
In accordance with the function <em>velocity</em>, the car will have a complete stop after 6 seconds.
<h3>When does the car stop?</h3>
Herein we have a function of the velocity of a car (v), in feet per second, in terms of time (t), in seconds. The car stops for t > 0 and v = 0, then we have the following expression:
0.5 · t² - 10.5 · t + 45 = 0
t² - 21 · t + 90 = 0
By the <em>quadratic</em> formula we get the following two roots: t₁ = 15, t₂ = 6. The <em>stopping</em> time is the <em>least</em> root of the <em>quadratic</em> equation, that is, the car will have a complete stop after 6 seconds.
