- Quadratic Formula:
, with a = x^2 coefficient, b = x coefficient, and c = constant.
Firstly, starting with the y-intercept. To find the y-intercept, set the x variable to zero and solve as such:

<u>Your y-intercept is (0,-51).</u>
Next, using our equation plug the appropriate values into the quadratic formula:

Next, solve the multiplications and exponent:

Next, solve the addition:

Now, simplify the radical using the product rule of radicals as such:
- Product Rule of Radicals: √ab = √a × √b
√1224 = √12 × √102 = √2 × √6 × √6 × √17 = 6 × √2 × √17 = 6√34

Next, divide:

<u>The exact values of your x-intercepts are (-4 + √34, 0) and (-4 - √34, 0).</u>
Now to find the approximate values, solve this twice: once with the + symbol and once with the - symbol:

<u>The approximate values of your x-intercepts (rounded to the hundredths) are (1.83,0) and (-9.83,0).</u>

Step-by-step explanation:
Answer:
y=2.5x+5 or f(x)=2.5x+5
Step-by-step explanation:
We know 2 given points. (-2, 0) and (0,5)
With these two points we can calculate the slope:
0-5/-2-0+
-5/-2=
5/2 = 2.5
Because the y-intercept is given at 5, we can put these numbers into y=mx+b and get y=2.5x+5 or f(x)=2.5x+5
Answer:
the last option, effectively cooling the hot plate down and heating the surrounding up
362/1,000. 362 is the numerator and when you say it out loud and you end it with the word thousandths that is the denominator hoped this help.
