X2+4x+3 solve for x.

mario62 [17]

Answer:

(x+1)(x+3)

Step-by-step explanation:

Let's factor x^2+4x+3

x^2+4x+3

The middle number is 4 and the last number is 3.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 4

Multiply together to get 3

Can you think of the two numbers?

Try 1 and 3:

1+3 = 4

1*3 = 3

Fill in the blanks in

(x+_)(x+_)

with 1 and 3 to get...

(x+1)(x+3)

A veggie wrap at Dylan's Diner is composed of 3 different vegetables and 3 different condiments wrapped up in a tortilla. If the

rosijanka [135]

Answer:

$5C1 (9C3) (5C3)$

And replacing we got:

$\frac{5!}{1! 4!} (\frac{9!}{3! (9-3)!}) (\frac{5!}{3! (5-3)!}) = 5*84*10=4200$

So then we have a total of 4200 possibilities in order to have a veggle wrap

Step-by-step explanation:

For this case we can use the combinatory formula given by:

$nCx= \frac{n!}{x! (n-x)!}$

And for this case we have a total of 9 vegatables and 5 condiments and 5 types of tortilla. Then the total number of possibilities are:

$5C1 (9C3) (5C3)$

And replacing we got:

$\frac{5!}{1! 4!} (\frac{9!}{3! (9-3)!}) (\frac{5!}{3! (5-3)!}) = 5*84*10=4200$

So then we have a total of 4200 possibilities in order to have a veggle wrap

Find the equation of the line.<br> Use exact numbers

klasskru [66]

Answer:

$y=-\frac{1}{3} x+5$

Step-by-step explanation:

This question is asking for slope-intercept form which is y=mx+b, where m is the slope and b is the y-intercept. First, find the slope; this can be done in two ways, counting change in y and x then dividing, or using the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ . Either way for this graph the slope comes out as -1/3. Next, find the y-intercept, this is where the line intersects with the y-axis. In this case, the line touches the axis at 5, therefore 5 is the value of b.
