What multiplies to 378 and adds to -51
Oliga [24]
Your answer would be -9 & -42. 

Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.

Hope this makes sense & helps you ! (:

G(x)=2x-2 <br> f(x)=x^2+3x <br> find (g of f)(2+x)
Bumek [7]

Answer:

Step-by-step explanation:

G(f(2+x))=g(2+x)^2+3(2+x)=2(2+x)^2+3(2+x)-2=2(4+4x+x^2)+6+3x=8+8x+2x^2+6+3x=2x^2+11x+14

Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that?
Jobisdone [24]

Answer:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8} x -  \frac{7}{8}

Step-by-step explanation:

The given system is

3x-2y=6

0.4(20y+15)=x

The slope intercept form is y=mx+c.

For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

y =  \frac{3}{2}x - 3

For 0.4(20y+15)=x, we expand to get:

8y  + 7 = x

8y= x - 7

Divide through by 8

y =  \frac{1}{8}x -  \frac{7}{8}

Therefore the system in slope-intercept form is:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8}x -  \frac{7}{8}

Can someone please help me it’s urgent
Evgen [1.6K]

Answer:

8.5 in

Step-by-step explanation:

You are solving for the hypotenuse right? So you would use this formula:

c = square root a^2+b^2

the c is the hypotenuse (long side of a right triangle) and a will be 4 and b will be 7.5. substitute the numbers in, solve, and you get 8.5 inches!

x = square root 4^2 + 7.5^2

x = square root 16 + 56.25

x = square root 72.25

x = 8.5 inches

The chance of picking a almond cookie the first time:
you have 6 cookies, 3 of them are almond
So the chance of taking an almond cookie is
\frac{3}{6}  =  \frac{1}{2}
The second time there are 5 cookies left, 2 of them are almond cookies
The chance of taking an almond cookie is
\frac{2}{5}
To know the probability of picking two almond cookies in a row, multiply the changes:
\frac{1}{2}  \times  \frac{2}{5}  =  \frac{1}{5}
The chance of taking two almond cookies is 1/5
