Given the function f(x) = 5x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.

Debora [2.8K]

$f(x)=5x\\\frac{f(1)-f(0)}{1-0}\\\frac{5-0}{1}\\5\\\\\frac{f(3)-f(2)}{3-2}\\\frac{15-10}{1}\\5$

A: 5; 5

B: 1; they are the same

Solve each system of equations using substitution. x×y=5 4+y=-x

valina [46]

Answer:

Step-by-step explanation:

$\left \{ {{xy=5} \atop {4+y=-x}} \right.\\\\ \left \{ {{xy=5} \atop {x=-4-y}} \right.\\\\=> \left \{ {{(-4-y)y=5} \atop {x=-4-y}} \right. \\\\ \left \{ {{-y^{2}-4y =5} \atop {x=-4-y}} \right. \\\\ \left \{ {{y^{2}+4y+5 =0} \atop {x=-4-y}} \right.$

because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R

=> y² + 4y + 5 = 0 is unreasonable

=> no solutions
