Answer:
a
Step-by-step explanation:
The equation of the line is 
Explanation:
Given that the line passes through the points (-5,-3)
The slope of the line is 
We need to determine the equation of the line.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Let us substitute the points (-5,-3) and the slope
in the above formula.
Thus, we have;

Simplifying, we get;

Subtracting 3 from both sides of the equation, we get;

Hence, the equation of the line in slope - intercept form is 
F(x)=-5t^2+20t+60
Divide everything by -5
f(x)=t^2-4t-12
(t-6)(t+2)
Set it up to zero
t-6=0. t+2=0
t=6. t=-2
Since you can’t have negative seconds, the answer is 6 seconds
The baker needs to use 100/3 pounds of 90% chocolate to make the cake.
<h3>
Equation </h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the amount of 90% chocolate. Using equation:
100 * 70% + x * 90% = (x + 100) * 75%
100 * 0.7 + 0.9 * x = (x + 100) * 0.75
70 + 0.9x = 0.75x + 75
x = 100/3
The baker needs to use 100/3 pounds of 90% chocolate to make the cake.
