Steps:
3x - 2(0) = 6
3x = 6
X = 2

Plug 2 into the equation

3(2) - 2y = 6
6 - 2y = 6
6 = 6 + 2y
0 = y

If this is wrong try doing it the opposite way which is:

3(0) - 2y = 6
-2y = 6
Y = -3

3x - 2(-3) = 6
3x + 6 = 6
3x = 0
X = 0

Answer:

3x= 2y +6

and when we put y = 0

then 3x = 6

x = 6/3

x =2

SECOND one , when we put x = 0

0= 2y +6

-6 = 2y

-6/2= y

-3 = y

Rainbow [258]

Answer: 60 of the patients are boys.

Step-by-step explanation: According to what is described, 5 in 8 patients are girls, then: 8 - 5 = 3, i.e., 3 in 8 are boys.

Mathematically the proportionality is \frac{3}{8}

If 160 patients have appointments per month and \frac{3}{8} are boys:

160.\frac{3}{8} = 60

Per month, 60 boys have appointments at the medical office.

tiny-mole [99]

Ok, so the question is based on geometric progression. Remember, the formula for calculating the nth-term of a geometric progression is: a*r^{n-1}. The a in the expression stands for the 1st term of the sequence, and r is the common ratio of the elements of the sequence. Now let's take a look at the problem.

"A ping pong ball has a 75% rebound ration". We can infer that our common ratio, r, is 75% which is 0.75.

"When you drop it from a height of k feet...", this means the first height you drop it from, a.k.a, the first term.

Now going back to the expression, the nth-term = a*r^{n-1}, we can substitute our common ration, 0.75 with r, and our 1st term, k, with a. This becomes: k * 0.75^{n-1}. This becomes our expression.

a. The highest height achieved by the ball after six bounces. Our nth-term here is 6, so let's use our expression to find the 6th term. n_{6} = 235 * 0.75^{6-1} = 235*0.75^{5} = 235*0.2373 = 55.7655ft

b. The total distance travelled by the ball when it strikes the ground for the 12th time. This involves the use of the sum of elements in the geometric progression. The formula for that is \frac{a(1 - r^{n})}{1-r}, provided that r is less than 1, which it is in this case, since 0.75 is less than one. Our nth-term here is 12, so we substitute.

\frac{235(1-0.75^{12})}{(1-0.75)} = 910.2242ft

You created a scale drawing with the scale 1:8. The client asked you to change it to a scale of 1:10. Will your revised drawing
myrzilka [38]

Answer:

The revised drawing be larger or smaller than your original one

Step-by-step explanation:

The revised drawing be larger or smaller than your original one.

Because   a drawing at a scale of:

  • 1:10 means that the object is 10 times smaller than in real life scale 1:1
  • 1: 8 means that the object is 8 times smaller than in real life scale 1:1

So it means the revised drawing be larger or smaller than your original one
