Y = x^2 + 11x + 24 = (x + 8)(x + 3)

Answer:

Option a is correct.

Step-by-step explanation:

We have been given the expression:

y=x^2+11x+24

We will factorize the given quadratic equation:

x^2+8x+3x+24

\Rightarrow x(x+8)+3(x+8)

\Rightarrow (x+8)(x+3)

Hence, the given equation is equivalent to (x+8)(x+3)

Hence, the graph will be equivalent to y=(x+8)(x+3)

Therefore, option a is correct.

Complete the equation of the line through (2, -2) and (4,1)
Ann [662]

Answer:

y = 3/2x - 5

Step-by-step explanation:

To find the equation of the line

Step 1: find slope

( 2 , -2) ( 4 , 1)

x_1 = 2

y_1 = -2

x_2 = 4

y_2 = 1

Insert the values into

m = (y_2 - y_1) / (x_2 - x_1)

m = ( 1 - (-2) / (4 - 2)

= ( 1 + 2) / ( 4 -2 )

= 3 / 2

m = 3/2

Step 2: substitute m into the equation

y = mx + c

y = 3/2x + c

Step 3: substitute any of the two points into the equation

Let's pick (4 , 1)

x = 4

y = 1

y = 3/2x + c

1 = 3/2(4) + c

1 = 3*4/2 + c

1 = 12/2 + c

1 = 6 + c

1 - 6 = c

c = 1 - 6

c = -5

Step 4 : substitute c into the equation

y = 3/2x + c

y = 3/2x - 5

The equation of the line is

y = 3/2x - 5

(18) POINTS pLEASE HELP
JulijaS [17]

Answer:

(x-4)(x-3)

Step-by-step explanation:

x^{2} -7x+12\\

multiply 1 and 12= 12

find two numbers that multiply to get twelve AND add together to get -7(the middle number)

the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)

plug in these numbers for -7x

x^{2} -3x-4x+12

x(x-3)-4(x-3)

the bolded is the first binomial and the second binomial is in the parenthesis.

(x-4)(x-3)

I hope this helps!

PLEASE ANSWER ASAP WILL MARK BRAINLIEST
katrin2010 [14]

Answer:

48 hats and 104 shirts

Step-by-step explanation:

These are the equations you build from the problem:

h + s = 152

8.50h + 12s = 1656

This is how I solved them:

s= 152-h

8.5h + 12(152-h) = 1656

8.5h + 1824 - 12h = 1656

Solve for h

h= 48

Put this into first equation (h +s = 152) to get s
