(4,7)(0,7)

notice how ur points have the same y values....this means this is a horizontal line with a slope of 0.

equation is : y = 7...or y = 0x + 7...but we need it in standard form...
0x + y = 7 <== standard form

2(h-8) -h=h-16 A. 8 B. -8 C. No solution D. Infinitely many solutions

Grace [21]

Answer:

D. Infinitely many solutions

Step-by-step explanation:

The equation simplifies to ...

2h -16 -h = h -16

h -16 = h -16 . . . . . . a "tautology", true for all values of h.

There are infinitely many solutions.

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

$=\frac{65}{100}*80*100\\\\= 65*80\\= 5200$

Amount paid for next 50 watches = (55% of 80) * 50

$= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200$

Remaining watches = 280 -(100+ 55)

= 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

$= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500$

Amount received by the watch maker = 5200 + 2200 + 4500

= £ 11900

Answer:

First question answer: The limit is 69

Second question answer: The limit is 5

Step-by-step explanation:

For the first limit, plug in $x=8$ in the expression $(9x-3)$ , that's the answer for linear equations and limits.

So we have:

$9x-3\\9(8)-3\\72-3\\69$

The answer is 69

For the second limit, if we do same thing as the first, we will get division by 0. Also indeterminate form, 0 divided by 0. Thus we would think that the limit does not exist. But if we do some algebra, we can easily simplify it and thus plug in the value $x=1$ into the simplified expression to get the correct answer. Shown below:

$\frac{x^2+8x-9}{x^2-1}\\\frac{(x+9)(x-1)}{(x-1)(x+1)}\\\frac{x+9}{x+1}$

Now putting 1 in $x$ gives us the limit:

$\frac{x+9}{x+1}\\\frac{1+9}{1+1}=\frac{10}{2}=5$

So the answer is 5
