Let
d = cost of a computer desk
c = cost of an office chair

4d + 3c = 1110
2d + 5c = 940

multiply (2nd) equation by 2

4d + 3c = 1110
4d + 10c = 1880
------------------------subtract
-7c = - 770
 c = 110

2d + 5c = 940
2d + 5(110) = 940
2d = 550 = 940
2d = 390
d = 195


answer
<span>cost of a computer desk = $ 195</span>

Answer:

hi

Step-by-step explanation:

i think so,

(5x-54)⁰=(3x+16)⁰

5x-3x=16+54

2x=70

x=35⁰

3x+16=3×35+16=121

5x-54=5×35-54=121

hope it helps

have a nice day

Write the number in witch the digit 2 is one tenth the value of the digit 2 in 8.524.
spin [16.1K]
Well the 2 in 8.524 would be 0.02 or 2 hundredths. Here's my explanation, the 8 is the whole number because it's before the decimal point, the 5 is the tenth or 0.5 and as you go further the number gets smaller so after the 5 is the 2 and that would be 2 hundredths or 0.02. So basically it's like going from tens, to hundreds, to thousands but only going in reverse order.

Y=8x-3/-4x-10 has a vertical asymptote with equation(enter equation of the vertical asymptote
xz_007 [3.2K]

Answer:

x=-2.5 if the function is f(x)=\frac{8x-3}{-4x-10}

Step-by-step explanation:

y=\frac{8x-3}{-4x-10} has discontinuities when the denominator is 0.

You will either have a hole or a vertical asymptote depending on what happens to the numerator after you find when the bottom is 0.

That is whatever you found that makes the bottom 0, if it makes the top also 0 then you will have a hole at x=the number that made the bottom 0.

If it makes the top anything other than 0, then it is a vertical asymptote at x=the number you found that made the bottom 0.

Let's do this now.

When is -4x-10 equal to 0?

We have to solve the equation:

-4x-10=0

Add 10 on both sides:

-4x=10

Divide both sides by -4:

x=10/-4

Reduce by dividing top and bottom by 2:

x=5/-2

x=-5/2

or

x=-2.5  (if you want decimal form)

Now does it make the top 0? This is the deciding factor on whether you have a hole at x=-2.5 or a vertical asymptote at x=-2.5.

Let's see.

8(-2.5)-3=-23

Since the top is not 0 at x=-2.5 then you have a vertical asymptote at x=-2.5.

If the top were 0, then you would have had a hole at x=-2.5.
