To solve the system of equations below, Grace isolated the variable y in the
first equation and then substituted into the second equation. What was the
resulting equation?
2y = 10x
x y²
64 36
= 1

Answer:

It depends on the number of charms that your bracelet can have.

here we need to count the number of selections that we have, and the number of options for each one of these selections.

So if we can have only one charm, we have only one selection, and for that selection, we have 9 options, then there are 9 different one-charm bracelets.

If each bracelet can have 2 charms then we have two selections.

For the first selection, we have 9 options,

If each charm can be selected only one time, then for the next selection we will have 8 options, now the total number of combinations is equal to the product between the numbers of options for each selection, so here the total number of combinations is:

C = 9*8 = 72

If we can select 3 charms, then:

first charm = 9 options

second charm = 8 options

third charm = 7 options

Total number of combinations = 9*8*7 = 504 combinations.

Notice that we can not give an exact answer because we do not know the number of charms in each bracelet and we do not know if a charm can be selected multiple times or only one, but here you could see the general way to solve this kind of problems.

Answer:

x = 9

Step-by-step explanation:

If g(x) = 3, that means that the output is three.

Outputs are y values.

Look at the graph. When y=3, the x  = 9.

So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9

Answer:

  a) zeros: -2/3, 6

  b) x < -2/3, signs: -, -; sign of product: +

  -2/3 < x < 6, signs: +, -; sign of product: -

  x > 6, signs: + +; sign of product: +

  c) solution: x < -2/3 ∪ x > 6

Step-by-step explanation:

a) The zeros of the product are the values of x that make either factor zero. (A product is only zero if one of the factors is zero.)

  3x +2 = 0   ⇒   x = -2/3

  x -6 = 0   ⇒   x = 6

The zeros of the quadratic are x = -2/3 and x = 6.

__

b) For values of x left of the left-most zero, both factors are negative. For values of x between the zeros, the left factor is positive and the right factor is negative. For values of x greater than the right-most zero, both factors are positive. That is, for large negative values of x, all factors are negative. Working left-to-right, each time a zero is crossed, one factor changes sign.

__

c) The solution is where the signs of the factors match:

  x < -2/3 or -6 < x

Answer: h -18 =14

Step-by-step explanation:

You need to plug in -18 into the equation. So h(-18)=17+(-18)/6

h(-18)=17-3

h(-18)=14

Answer:

D) 100

Step-by-step explanation:

Solution: After four hours, one car travels 40 x 4 = 160 km, and the other car travels 35 x 4 = 140 km. Therefore, the two cars are 160 + 140 - 200 = 100 km apart

Answer:

y = -3x + 5

Step-by-step explanation:

Since the y-intercept occurs at the point (0,5), you can use that and the point slope equation to find the equation.

This looks like y - 5 = -3 (x - 0);

Solving for y, you get y = -3x + 5;

To graph this equation you would put one point at (0,5), then use the slope to count down three and to the left one to find other points, or you could just plug in numbers for x to find their corresponding y values and plot it like that.

Hopefully this helps- let me know if you have any questions!

Answer: 18 questions

Step-by-step explanation:

First we want to make 60% a decimal so we divide by 100.

This gives us 0.6

Then we multiply 30*0.6=18

Answer:

i think this

Step-by-step explanation:

Let Va = the velocity of the airplane

Let Vw = the velocity of the wind

When flying with the wind:

(Va+Vw)*(4 hours) = 4000

4Va + 4Vw = 4000

4Vw = 4000 - 4Va

Vw = 1000 - Va

When flying against the wind:

(Va-Vw)*(7 hours) = 4200 km

7Va - 7Vw = 4200

Substitute 1000-Va for Vw and solve for Va:

7Va - 7(1000-Va) = 4200

7Va -7000 + 7Va = 4200

14Va = 11200

Va = 800 km/hr

Rate of wind:

Vw = 1000 - Va = 1000 - 800 = 200 km/hour

b. The accessible population

c. The sample

d. The statistic

Step-by-step explanation:

a. All the homeowners in the researchers state = The target population

b. The 879 homeowners whose name were obtained = The sample frame (accessible population)

c. The 64 homeowners who returned the questionnaire = Research participants (the sample), the subjects

d. The 80% who stated that the current home warranty coverage needs to be completely overhauled = The statistic (subset or part of the sample)

Answer:

4x19+4x2  or  4x21

Step-by-step explanation:

If you multiply 4x19, you get  76. And if you multiply 4x2 you get 8. 76+8= 84

If you multiply 4x21 you get 84 also.  Both of these answers are distributive property. (all it is, is different ways of solving the problem.)

Hope this helps!  :)
