Let's solve your system by substitution.
a=−2;b=−3
Step: Solve a=−2for a:
a=−2
Step: Substitute−2for a in b=−3:
b=−3
b=−3
Answer:
a=−2 and b=−3
You just have to plug in each value of x into the equation of 3x^2. Since y is a function, it is also written as f(x)
B Bc it’s a right triangle meaning it’s 90 degrees so 90-10 is 80 and 80 divided by 2 is 40
