Decimal Question: 15 centimeter and nine millimeter = how much centimeters

Answer:

Step-by-step explanation:

To solve using completing square, we need to write the equation as x2+3x=17.

The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4

The equation then becomes x2+3x+(9/4)=17+(9/4).

Solving it further will get you the final answer

Answer:

7 is the answer

Step-by-step explanation:

.75 * -4 + 10 = -3+10 = 7

Answer:

x=12

y=6

Step-by-step explanation:

Let's first start by moving x and y to one side (I prefer having both variables on the same side and the other number on the other side):

3x-y=30

-3x+7y=6

Add the equations to eliminate x

6y=36

Divide both sides by 6

y=6

3x-30=6

Add 30 to both sides

3x=36

Divide both sides by 3

x=12

(x,y)=(12,6)

Hey there :)

An exact answer cannot be given as it requires to reseach about banks and co-operatives in your locality. However, I can give you a hint.

Research banks or cooperatives in your location that has the greatest percentage in terms of investment or savings.

Let's say, for example, Bank ABC has 5% annual simple interest in their Savings Account.

If you invest your entire money 100,000 pesos at Bank ABC with 5% annual interest for 20 years, you will earn an interest of:

[tex]Interest = Principal \times Rate \times Time[/tex]

[tex] = > Interest =100000 \times 0.05 \times 20yrs[/tex]

[tex] = > Interest = 100000[/tex]

Hence, after investing at Bank ABC for 20 years, you will earn 100,000 pesos on top of your principal/invested amount that is 100,000 pesos. Your money will become 200,000 pesos now.

So, with this, find a bank/cooperative that has the highest return rate in your location. Once you have decided bank/cooperative, research further with regards to the background of the company, other services offered, application requirements, etc.

Answer:

1. has solution x=-2 and goes in the left circle

2. has solutions x=-2 and x=5 and goes in the intersection between the two circles

3. has solution x=-2 and goes in the left circle

4. has solution x=5 and goes in the right circle

Step-by-step explanation:

Solve each equation by factoring

2x^2-12x-32=0

2(x^2-6x-16)=0

2(x+2)(x-8)

x=-2,x=8

Therefore, 1. has solution x=-2 and goes in the left circle

2x^2-6x-20=0

2 (x^2-3x-10) = 0

2(x-5)(x+2)=0

x=-2,x=5

Therefore, 2. has solutions x=-2 and x=5 and goes in the intersection between the two circles

3x^2+2x-8=0

(x+2)(3x-4)=0

x=-2, x=4/3

Therefore, 3. has solution x=-2 and goes in the left circle

3x^2-18x+15=0

3(x^2-6x+5)=0

3(x-1)(x-5)=0

x=1,x=5

Therefore 4. has solution x=5 and goes in the right circle

y = 2x-8

========================================================

Explanation:

Let's find the slope of the line through (2,7) and (4,11).

[tex](x_1,y_1) = (2,7) \text{ and } (x_2,y_2) = (4,11)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{11 - 7}{4 - 2}\\\\m = \frac{4}{2}\\\\m = 2\\\\[/tex]

The slope is 2.

Any line parallel to this current line will have the same slope, but different y intercept.

Choice B has the same slope (2), so this is why it's the final answer.

Sᴏʟᴜᴛɪᴏɴ Fᴏʀ Wᴇɪʀᴅ Tᴇᴇɴʏ ~

[tex] \qquad \sf  \dashrightarrow \: 4(5x - 2) = 2(9x + 3)[/tex]

[tex]\qquad \sf  \dashrightarrow \: 20x - 8 = 18x + 6[/tex]

[tex]\qquad \sf  \dashrightarrow \: 20x - 18x = 6 + 8[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x = 14[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 14 \div 2[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 7[/tex]

Therefore value of x is 7

By solving the linear equation, we will see that the solution is x = 7.

Here we need to solve the equation:

[tex]4*(5x - 2) = 2*(9x + 3)[/tex]

First, we should distribute the two products to get:

[tex]4*5x - 4*2 = 2*9x + 2*3\\\\20x - 8 = 18x + 6[/tex]

Now we move the terms with x to the left, and the terms without x to the right.

[tex]20x - 8 = 18x + 6\\\\20x - 18x = 6 + 8\\\\2x = 14\\\\[/tex]

Now we can divide both sides by 2 to get:

[tex]x = 14/2 = 7\\x = 7[/tex]

So the solution of the linear equation is x = 7.
