What is the solution to the equation 3x + 2(x − 9) = 8x + x − 14? (1 point)

solong [7]

Answer:

B. -1

Step-by-step explanation:

STEP 1: Simplify 3x+2(x−9).

$5x-18=8x+x-14$

STEP 2: Add 8x and x.

$5x-18=9x=-14$

STEP 3: Move all terms containing x to the left side of the equation.

$-4x-18=-14$

STEP 3: Move all terms not containing x to the right side of the equation.

$-4x=4$

STEP 4: Divide each term by −4 and simplify.

$x=-1$

Container a and b hold 11,875 liters of water altogether. Container b holds 2,391 liters more than container a holds. How much w

Viefleur [7K]

Container A holds x liters of water.
Container B holds 2391 liters of water more than container A, so container B holds x+2391 liters of water.
Container A and B hold 11875 liters of water altogether.

$x+x+2391=11875 \\
2x+2391=11875 \\
2x=11875-2391 \\
2x=9484 \\
x=\frac{9484}{2} \\
x=4742$

Container A holds 4742 liters of water.

Which is the graph of y= cos(x-pi)

marshall27 [118]

Answer:

graph attached

Step-by-step explanation:

A graph is a pictorial representation that represent the relationship between two or more things.

Cosine function is periodic with period $2\pi$ . If the point $(x,y)$ lies on the graph, point $(x+2k\pi ,y)$ will also lie on the graph where k is any integer.

Here,

$cos(x-\pi )=cos[-(\pi -x)]=cos(\pi -x)=-cos x$
