Answer:

x=4, x=3

B is correct.

Step-by-step explanation:

Given: x^2-7x+12=0

Using middle term splitting factor the left side equation.

x^2-4x-3x+12=0

(x-4)(x-3)=0

Equate each factor to 0 and solve for x

x-4=0    or     x-3=0

x=4 and x=3

Hence, The solution of the equation is 4 or 3

Bob's Skate Shop had a profit of $3,563 during the month of August. The company models its profit using p=x^2+10x-12 where x is
Elis [28]
I entered the equation into a graphing calculator. clicked table and then scrolled down to the profit of $3,563. 55 skateboards
you could also try this equation. B=the number attached to x so 10, a=the number attached to x^2(or in other equation x^3 etc) so 1 and c is the number, so -12.

The function h is a quadratic function whose graph is a translation 3 units left and 4 units up of the parent
jeka57 [31]

Answer:

D ( if you add +4 to the (x + 3)^2)

Step-by-step explanation:

Parent function is f(x) = x^2

A translation 3 units left gives y = )x + 3)^2

- and 4 up gives y = (x + 3)^2 + 4 - vertex form.

Standard form :

y = x^2 + 6x + 9 + 4

= x^2 + 6x + 13.

Y = 3x − 8
Nana76 [90]

Answer:

A. You would first plot the y intercept.  The first equation would be (0,-8) and the second equation is (0,-11).  Then you would plot the slope.  For the first equation, from (0,-8), you would move up 3 plots and right 1 plot.  For the second equation, from (0,-11), you would move up 9 plots and right 1 plot.

B. The solution to the pair of inequalities is (1/2, -13/2).  That is the intersection and point of the two lines.  You would need to graph the two lines (see part A answer) and then find the intersection.  

Hope this helps!
