Arlecino [84]

Answer:

Y = -2X + 7

Step-by-step explanation:

Y = a(x-h)^2 + k

From (h,k) h = 0 k = 7 x = 2 y = 3

3 = a(2-0) + 7

3 = 2a - 0 + 7

Collect like terms

2a = 3 - 7

2a = -4

Divide both sides by 2

2a/2 = -4/2

a = -2

y = a(x-h) + k

y = -2(x-0) + 7

y = -2x + 0 + 7

y = -2x + 7 or

y + 2x - 7 = 0

Solve the following linear system by elimination. Check your solution:

shepuryov [24]

Answer:

(- 1, 1 )

Step-by-step explanation:

x + 5y = 4 → (1)

4x + 12y = 8 → (2)

multiplying (1) by - 4 and adding to (2) will eliminate x

- 4x - 20y = - 16 → (3)

add (2) and (3) term by term to eliminate x

0 - 8y = - 8

- 8y = - 8 ( divide both sides by - 8 )

y = 1

substitute y = 1 into either of the 2 equations and solve for x

substituting into (1)

x + 5(1) = 4

x + 5 = 4 ( subtract 5 from both sides )

x = - 1

As a check

substitute these values into the left side of both equations and if equal to the right side then they are the solution.

- 1 + 5(1) = - 1 + 5 = 4 = right side

4(- 1) + 12(1) = - 4 + 12 = 8 = right side

(- 1, 1 ) is the solution to the system of equations

two decimal numbers have digits to the thousands place if you multiply them how many digits do you expect there to be after the

disa [49]

There will be 6 decimal digits in the product of the numbers and can be fewer than 6.

<h3>What are decimal numbers?</h3>

A decimal number has a whole number and a fractional part.

Given that the two decimal numbers have digits to the thousandth place.

Therefore, there are three digits after the decimal point.

The number of digits after the decimal point in the product of two decimal numbers is the sum of the digits after the decimal point in both numbers.

Let the first number be 0.001 and the second number be 0.002.

Then, the number of decimal digits in the product of 0.001 and 0.002 will be 6.

If the two numbers are 0.005 and 0.002, then surely, there will be less than 6 digits after the decimal as the last 0 can be omitted in counting.

Hence, there will be 6 decimal digits in the product of the numbers and can be fewer than 6.

I need help in this section.

Phoenix [80]

Answer:

$\frac{1}{45}$

Step-by-step explanation:

There are

2 yellow

3 magenta

5 blue

marbles in the bag.

So total of 2 + 3 + 5 = 10 marbles

We have to multiply the probability of yellow on first pick by the probability of yellow on second pick (WITHOUT REPLACEMENT).

We denote P(Y1) as probability of yellow on first draw &

P(Y2) as probability of yellow on second draw

Thus,

P(Y1) = 2/10 = 1/5 [since 2 yellow and 10 total marbles]

Now,

P(Y2) = 1/9 [since now 1 yellow is taken out and NOT replaced, so we have 1 yellow remaining and total 9 marbles]

Now, we multiply:

P(Y1) * P(Y2) = 1/5 * 1/9 = 1/45

The probability is $\frac{1}{45}$
