The sign in front of the 2 is "-" meaning negative. So if it is -2, then that means the team lost yards. So, the Smart Blues lost 2 yards.

devlian [24]

Answer:

I'm gonna say maybe 10..... yah 10

here's why

Answer:

In can pick in 10 ways.

Solution:

John has green, red, yellow, purple, orange, and blue paint = total 6 colours

he wants to have 4 different colours in the painting.

But in those 4 colors green is must, it should always be there.

So except green we have total 5 colours (red, yellow, purple, orange, and blue) from which we can pick any 3 colors(as green will be one in four colours).

Then we can choose 3 colours from 5 colours in x ways.

x ways = = \left(\frac{5 !}{3 !(5-3) !}\right)=(3!(5−3)!5!)

=\left(\frac{5 !}{3 ! \times 2 !}\right)=(3!×2!5!)

=\frac{5 \times 4 \times 3 !}{3 ! \times 2 !}=3!×2!5×4×3!

=\frac{5 \times 4}{2}=25×4

=\frac{20}{2} = 10=220=10

Someone please help me!

bija089 [108]

Answer:

A = 58

B =:25

Step-by-step explanation:

C = A + B

83 = 9x + 4 + 4x + 1

83 = 13x + 5

13x = 78

x = 78/13

x = 6

A = 9x + 4 = 9 x 6 + 4 = 58

B = 4x + 1 = 4 x 6 + 1 = 25

Which is the maximum value of the function y=-3x2 - 15x+9?

blagie [28]

Answer:

Step-by-step explanation:

The maximum value of the function is the y- coordinate of the vertex.

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = - 3x² - 15x + 9 ← is in standard form

with a = - 3 and b = - 15, thus

$x_{vertex}$ = - $\frac{-15}{-6}$ = - 2.5

Substitute x = - 2.5 into the equation for y- coordinate of vertex

y = - 3(- 2.5)² - 15(- 2.5) + 9 = - 18.75 + 37.5 + 9 = 27.75 → B
