Solve the system by graphing. Tell whether the system has one solution, infinitely many solutions, or no solution.

masha68 [24]

Here: 6y = 6x + 12
6y - 6x = 12

Divide by 6,
y - x = 2
Which is nothing but first equation!

In short, Your Answer would be: "Infinitely Many solutions"
[ As L.H.S = R.H.S ]

Hope this helps!

1. Your cereal company wants to make a family size box for your most popular brand. Your current, 17 ounce, box costs $1.50 to f

HACTEHA [7]

Answer:

The cost to fill the new family size box will be $\$2.93$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

we have

$z=1.25$

$z^{3}=1.25^{3}=1.953125$

To find the new cost multiply the original cost by the scale factor elevated to the cube

$\$1.50(1.953125)=\$2.93$

The new volume would be

$17(1.953125)=33.20\ ounces$

Given that f(x)=x-3 and g(x)=x^2-x, find (f+g)(-2)

mario62 [17]

Answer:

(f + g)(- 2) = 1

Step-by-step explanation:

(f + g)(x) = f(x) + g(x) , thus

f(x) + g(x)

= x - 3 + x² - x

= x² - 3

Thus

(f + g)(- 2) = (- 2)² - 3 = 4 - 3 = 1
