Answer:

x= -674

Step-by-step explanation:

Solve for x and check: x + 5 = 3

Solution

Solve for x and check: - 3x = 12

Dividing each side by -3, we obtain

Another way of solving the equation

3x - 4 = 7x + 8

would be to first subtract 3x from both sides obtaining

-4 = 4x + 8,

then subtract 8 from both sides and get

-12 = 4x.

Now divide both sides by 4 obtaining

- 3 = x or x = - 3

Solve for c: 3(x + c) - 4y = 2x - 5c

First remove parentheses.

Remember, abx is the same as 1abx.

We divide by the coefficient of x, which in this case is ab.

Slope intercept form is y=mx+b
m=slope
b=y intercept

changing 2x+3y=1470 to sloepe intercept form is solving for y
minus 2x both sides and dvide by 3
$y=\frac{-2}{3}x+490$

the slope is -2/3
the y intercept is y=490 or the point (0,490)
to graph it, I would start at the origin and go up 490 units on the y axis and put a point there
then go -2 units up (2 down) and 3 to the right and put a point there
then connect the 2 points with a line

the graph represents the possible x and y values so tha tthe profit is 1470

in function notation, replace y with f(x) to get
$f(x)=\frac{-2}{3}x+490$
graph below
intercepts labeled

2x+3y=1593
they are similar because they have the same slope
the equation is $y=\frac{-2}{3}x+531$

How much interest will $875.00 earn after 3 months at 5.5%?

ZanzabumX [31]

Answer:

I = Prt

Substitute the given information. Remember to write the percent in decimal form. I = (500)(0.06)(3)

Simplify. I = 90

Check your answer. Is $90 a reasonable interest earned on $500 in 3 years? In 3 years the money earned 18%. If we rounded to 20%, the interest would have been 500(0.20) or $100. Yes, $90 is reasonable.

The simple interest is $90.

In 2010, Joe bought 200 shares in the Nikon corporation for $22.07 per share. In 2016 he sold the shares for $15.11each.

slega [8]

Answer: a. $1392

b. 31.5%

Step-by-step explanation:

a. What was Joe's capital loss?

Cost price = $22.07 × 200 = $4414

Selling price = $15.11 × 200 = $3022

Capital loss = $3022 - $4414

= -$1392

b. Express Joe's capital loss as a percent, rounded to the nearest percent.

= Capital loss/Cost price × 100

= 1392/4414 × 100

= 31.5%

The length of a rectangle is 1 more yd than twice the width, and the area of the rectangle is 66 yd squared. Find the dimensions

Salsk061 [2.6K]

Width = 5.5yd

Length = 12yd

Explanation:

Area of rectangle = $66yd^{2}$

Let width of the rectangle = b ,

So, length = 2b+1

Area of rectangle = (length X width) - eqn 1

Putting the value of length and width in above equation 1,

$66yd^{2} = (2b+1) X b\\66yd^{2} = 2b^{2} + b\\2b^{2} +b-66 = 0\\$

On solving the equation we get,

b = 5.5yd

So, width (b) = 5.5yd

and length = 2(5.5) + 1

l = 12yd

Hence,

Width = 5.5yd

Length = 12yd
