Step-by-step explanation:

2x + 3y = 2

x + 6y = 4

2(4-6y) + 3y = 2

x= 4- 6y

8-12y + 3y = 2

x= 4- 6y

-9y =-6 =) y = 2/3

x= 4- 6*2/3 = 0

Answer:

1. 135 2. 16.875

Step-by-step explanation:

1. 5 x 4.5 x 6 = 135

2. 2.5 x 2.25 x 3 = 16.875

Answer:

A - 29%

Step-by-step explanation:

Bianca's 1/5 would be converted to 20%

Chelsea's .26 would be 26%

Darnell's is 25%

Adding these together you get 71. To find the remaining votes that Francisco received you would..

Subtract

100 - 71 = 29%

Therefor, your answer is A.

If Darell earned 25% of the vote and Francisco received the remaining votes, Chelsea would have garnered 0.26 percent of the vote. 29% of the votes were cast in favor of Francisco. Option A is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Given that there were four candidates running for office in the school election, Bianca won 1/5 of the vote, Chelsea got 0.26, Darell got 25%, and Francisco got the remaining votes.

Bianca's 1/5 would be converted to 20% and Chelsea's .26 would be 26%, Darnell's is 25%

Adding these together you get 71. To find the remaining votes that Francisco received you would be applying the subtraction operations,

100 - 71 = 29%

Thus, if Darell earned 25% of the vote and Francisco received the remaining votes, Chelsea would have garnered 0.26 percent of the vote. 29% of the votes were cast in favor of Francisco. Option A is correct.

Answer:

[tex]0.00003=3[/tex]×[tex]10^{-5}[/tex]

[tex]2[/tex]×[tex]10^5[/tex] = [tex]200,000[/tex]

Step-by-step explanation:

When working with scientific notation, you are either given a decimal or whole number. The point of scientific notation is to rewrite a number in a more simplified form.You need to change the number so that there is one number on the left side of the decimal. An exponent is used to describe the change in the number. For example:

0.00003

In order to get one number to the left of the decimal, you need to move the decimal to the right 5 spaces. Since the zeros are to the left of the primary number (3), the exponent will be negative. The exponent itself will be the spaces you moved:

[tex]3[/tex]×[tex]10^{-5}[/tex]

The ten is used because of the decimal places you are moving. When you multiply a number by 10, you add a zero. For example:

[tex]2[/tex]×[tex]10^5[/tex]

Since there is a 10, we will be adding in zeros. The exponent determines how many zeros will be added. Since it is a positive number, the numbers will be to the right of the primary number:

200,000

Answer: 2i-11

Step-by-step explanation:

[tex](-2+5i)-(9+3i)\\-2+5i-9-3i\\2i-11[/tex]

Answer:

Step-by-step explanation:

Recognize that this is the exponential function y = e^x with some tweaks:

f(x) = 2e^x + 1, as compared to y = e^x.

y = e^x is a basic function that we all should know well.  Its graph looks much like the graph shown as "Part A."  The graph starts in Quadrant II, crosses the y-axis into Quadrant I, and then continues growing rapidly as x increases.

As x => positive infinity, y => positive infinity.  This is true of f(x) = 2e^x + 1 also.

As x => negative infinity, y => 0 (speaking of y = e^x).

As x => positive infinity, f(x) = 2e^x + 1 => positive infinity, in Quadrant I.

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

Explanation:

The half-life is 35 hours. This means every 35 hours, the amount of the substance is cut in half. If we started with 100 grams, then 35 hours later, we will have 50 grams. Then another 35 hours later we will then have 25 grams, and so on.

In this case, we start with 904 grams and follow this sequence:

904, 452, 226, 113, ...

Each term is cut in half. Going from term to term it takes 35 hours each. The third term 226 is the result of waiting two half-lives, which is 2*35 = 70 hours that have elapsed total.

--------------

If you want to use a formula, then it would be

[tex]y = A*\left(\frac{1}{2}\right)^{x/H}[/tex]

where,

H = half-life duration (in this case, it is 35)

A = starting amount (which is 904 in this case)

x = amount of time that has elapsed (we will plug in x = 70)

y = final amount after x units of time has elapsed

note that x and H must have the same time unit. Both are in terms of hours in this case.

------------

So we will plug A = 904, x = 70, H = 35 into the formula to get...

[tex]y = A*\left(\frac{1}{2}\right)^{x/H}\\\\y = 904*\left(\frac{1}{2}\right)^{70/35}\\\\y = 904*(0.5)^{2}\\\\y = 904*(0.25)\\\\y = 226\\\\[/tex]

We see that x = 70 leads to y = 226. This means after 70 hours, there is 226 grams of the material left.

Step-by-step explanation:

Both are working 40 hours a week, so together they work 80 a week. 80 hours a week for 4 weeks gives you 320 hours a month. $5312 divided by 320 hours gives you $16.60 per hour, Together you would have $33.20

Answer:

the length of the side XY is 4 units

Step-by-step explanation:

To find the length of side XY, what we do is to find the distance between the points X and Y

To find this distance, we employ the use of the formula for finding the distance between two points on a Cartesian plane.

Mathematically, the distance d which represents the length XY is given by;

d = √{(x2-x1)^2 + (y2-y1)^2}

Where point X represents the coordinates (x1,y1) = (10,1) while point Y represents the coordinates (x2,y2) = (10,-3)

Plugging these values into the formula, we have;

d = √{(10-10)^2 + (-3-1)^2}

d = √{(0)^2 + (-4)^2}

d = √(0 + 16)

d = √(16)

d = ± 4

but since distance cannot be negative, we ignore the -4 and thus we choose 4 units as the length between the points XY

Answer:

128

Step-by-step explanation:

The sum of angles in the triangle is 180 degrees

12 + 40 + x = 180

52 + x = 180

x= 180 - 52 = 128 degrees

(x is the third angle of the triangle)

The measure of the third angle of the triangle is 128degrees

The sum of an interior angle of a triangle is 180 degrees.

Let the third angle of the triangle be x, hence;

12 + 40 + x = 180

52 + x = 180

Subtract 52 from both sides

52 + x - 52 = 180 - 52

x = 180- 52

x = 128degrees

Hence the measure of the third angle of the triangle is 128degrees

4x^2 -16

Step-by-step explanation:

(2x + 4)(2x - 4)

FOIL

first:2x*2x = 4x^2

outer: -4 *2x = -8x

inner:  4*2x = 8x

last: -4*4 = -16

Add them together

4x^2 -8x+8x =-16

4x^2 -16

The multiplication of the expression (2x + 4)(2x - 4) is 4x² - 16.

Given the expression in the question:
(2x + 4)(2x - 4)

We can multiply the expression (2x + 4)(2x - 4) using the distributive property and the FOIL method.

(2x + 4)(2x - 4)

Apply the FOIL method:

2x( 2x - 4 ) + 4( 2x - 4 )

Apply distributive property:

2x × 2x + 2x × - 4 + 4 × 2x 4 × - 4

Multiply the terms:

4x² - 8x + 8x - 16

Collect and add like terms:

4x² - 16

Therefore, the simplified form is 4x² - 16.
