Solve using substitution x=(3y+1) and x+4y=15

natka813 [3]

The solution is: x= 7 and y = 2

Step-by-step explanation:

Given equations are:

$x = 3y+1\ \ \ \ Eqn\ 1\\x+4y = 15\ \ \ \ Eqn\ 2$

Putting x = 3y+1 in equation 2 from equation 1

$3y+1+4y = 15\\7y+1 = 15\\$

Subtracting 1 from both sides

$7y+1-1 = 15-1\\7y = 14$

Dividing both sides by 7

$\frac{7y}{7} =\frac{14}{7}\\y = 2$

Putting y=2 in equation 1

$x = 3(2) +1\\x = 6+1\\x = 7$

Hence,

The solution is: x= 7 and y = 2

F (x) = -4x² + 10x + 13

Alexus [3.1K]

Answer:

f(7) = -113

Step-by-step explanation:

Hello!

Substitute 7 for x in the equation.

<h3>Evaluate</h3>

f(x) = -4x² + 10x + 13
f(7) = -4(7)² + 10(7) + 13
f(7) = -4(49) + 70 + 13
f(7) = -196 + 70 + 13
f(7) = -113

f(7) is -113.
