Answer:

$(2a +1)( 2a + 1)$

Step-by-step explanation:

$1+4a+4a^2$

$=4a^2 +4a +1$

$=4a^2 +2a + 2a + 1$

$=2a(2a +1) +1( 2a + 1)$

$=(2a +1)( 2a + 1)$

Evaluate the expression for a = -1 and b = 5. shiw your work. 5a-7b+b2

Natasha2012 [34]

a = -1 and b = 5
5a-7b+b2
5(-1) - 7(5) + 5^2
-5 - 35 + 25
-40 + 25
-15

-15 would be the result

Solve the following system of equations by graphing.

MrMuchimi

Answer:

<h2>Graph b</h2>

Step-by-step explanation:

The equation of a linear function in slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The graph of linear function is a straight line therefore we need only two points to the plotting the graph.

$-4x+3y=-12\qquad\text{add 4x to both sides}\\\\3y=4x-12\qquad\text{divide both sides by 3}\\\\y=\dfrac{4}{3}x-4\\\\for\ x=0\to y=\dfrac{4}{3}(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=3\to y=\dfrac{4}{3}(3)-4=4-4=0\to(3,\ 0)$

$-2x+3y=-18\qquad\text{add 2x to both sides}\\\\3y=2x-18\qquad\text{divide both sides by 3}\\\\y=\dfrac{2}{3}x-6\\\\for\ x=0\to y=\dfrac{2}{3}(0)-6=0-6=-6\to(0,\ -6)\\\\for\ x=3\to y=\dfrac{2}{3}(3)-6=2-6=-4\to(3,\ -4)$
