The equation of the line that passes through (5, 15) and (2, 6) is y =3x.


True

False

Answer:

4. y = -1/2x + 5

5. y = -1/3x + 3

6. y = 1

Step-by-step explanation:

For #4:

Because these lines are parallel, we know that they will have the same slope.

To get b, or the y-intercept, I just started at the point (4,4) and used the slope to work backwards to the y-axis. This is really not the best way to do it (especially with big numbers) but it works in a pinch. Also, I forgot the better way :/

For #5:

These lines are perpendicular. That means that the slopes are reciprocals of the other and, when multiplied with each other, the answer will be -1.

The reciprocal of 3 is -1/3.

To get the y-intercept, I did the same as above.

For #6:

x = 2 is a vertical line. To make a line perpendicular to it, that is, to make a line that intersects with it at 90°, the answer line will have to be horizontal.

That means that our answer is y = ?

We know that the line passes through a very specific point (2,1), and the line provided in the question already gives us the x value of this point. All we have to do is set y equal to the y value.

So, y = 1.

I hope this helps!

−70%

Step-by-step explanation:

Hope this helps, If it did, then I would really appreciate it if you gave me Brainliest, I only need one more to rank up and it has taken forever to get to where I am currently. Thanks.

There is -70% change when value change from 10 to 3.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

The original value is 10,

The value is change to 3

The difference of changed value and original value =  3 - 10 = -7

The percentage of change = (-7/10)x100

                                             = -70%

The change in percent is -70%, negative sign shows that value decreases.

Answer:

Step-by-step explanation:

Total out come is 38

Favorable outcome is 1

Probability is 1/38 ≈ 0.026

The probability of winning if you pick the number 30, and it comes up on the wheel, will be 0.026.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00.

Then the total number of the event will be

Total event = 38 {0, 00, 1, 2, …, 36}

Then the probability of winning if you pick the number 30, and it comes up on the wheel will be

Favorable event = 1 {30}

Then the probability will be

P = 1 / 38

P = 0.026

Answer:

The correct answer is D.

Step-by-step explanation:

Option A establishes that 4 dozen bagels and 3 dozen muffins will be prepared, thus spending $ 30 and 3 hours on muffins and $ 60 and 12 hours on bagels. In total, $ 90 and 15 hours will be spent, so this option is not correct.

Option B establishes that 2 dozen bagels and 6 dozen muffins will be prepared, thus spending $ 60 and 6 hours on muffins and $ 30 and 6 hours on bagels. In total, $ 90 and 12 hours will be spent, so this option is not correct either.

Option C states that 3 dozen bagels and 1 dozen muffins will be prepared, which will spend $ 10 and 1 hour on muffins and $ 45 and 9 hours on bagels. In total, $ 55 and 10 hours will be spent, so this option is not correct.

Finally, option D establishes that 1 dozen bagels and 3 dozen muffins will be prepared, thus spending $ 30 and 3 hours on muffins and $ 15 and 3 hours on bagels. In total, $ 45 and 6 hours will be spent, with which this option is within the predetermined parameters, that is, the expense is less than $ 60 and the time is less than 8 hours.

Answer:

Rate of simple interest = 4%

Step-by-step explanation:

Formula for simple interest is;

A = P(1 + rt)

Where;

P is principal

r is rate

t is time

Now, we are told that he borrowed $6,500 from the bank and that 5 years later, he owes the bank $7,800.

This means;

P = 6500

t = 5 years

A = 7800

Thus;

7800 = 6500(1 + 5r)

7800/6500 = 1 + 5r

1.2 = 1 + 5r

Subtract 1 from both sides to get;

1.2 - 1 = 1 - 1 + 5r

0.2 = 5r

r = 0.2/5

r = 0.04 or 4%

6.78ft/sec

Step-by-step explanation:

From the question, dx/dt= 3.9 ft/sec

We are looking for Dy/dt

From geometry,vof this case the relationship between x and y is needed here, there is two similar triangle that exhibited by the man and the lamb

12/y= 5.1/(y-x)

Then ,cross multiply, we have

12(y-x)=5.1y

12y-12x=5.1y

12y-5.1y=12x

6.9y=12x

y=( 12/6.9)x

Differentiating implicitly the bother sides with respect to t, we have

Dy/dt= ( 12/6.9)dx/dt

But dx/dt= 3.9 ft/sec

Then Dy/dt= ( 12/6.9)× 3.9

Dy/dt=6.78ft/sec

Hence, the rate that the tip of the person's shadow moves away from the lamppost when the person is 9 ft away from the lampost is 6.78ft/sec

The value of z/w is, (8 + 2i)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The graph is shown in figure.

And, The point z = (6 + 10i)

The point w = (1 + i)

Now,

We can find the value of z/w is,

⇒ z/w = (6 + 10i) / (1 + i)

         = (6 + 10i) (1 - i) / (1 + i) (1 - i)

          = (6 - 6i + 10i - 10i²) / (1 - i²)

          = (6 + 4i + 10) / (1 + 1)

          = (4i + 16) / 2

          = (8 + 2i)

Answer:

Step-by-step explanation:

i really dont know pls help PAHAHA

The baby's weight at the birth of the baby was 7 pounds.

Given is that a linear model of this situation contains the values (1, 7.3) and (9, 9.7), where [x] represents the number of weeks, and [y] represents the baby's weight, in pounds.

Assume the equation of the line in slope - intercept form is -

y = mx + c

Now -

m = (9.7 - 7.3)/(9 - 1)

m = 2.4/8

m = 0.3

The equation will be -

y = 0.3x + c

For the point - (1, 7.3), we can write -

7.3 = 0.3 x 1 + c

c = 7.3 - 0.3

c = 7

Therefore, the baby's weight at the birth of the baby was 7 pounds.

Step-by-step explanation:

Answer:

The son received 2,615.38.

Step-by-step explanation:

In order to know how much the son received, it is best to use algebraic expressions in finding the children's individual shares.

Let x be the son's share and [tex]\frac{3x}{4}[/tex] be the share of each daughter.

The equation will be: 8,500 = x + [tex]\frac{3x}{4}[/tex] + [tex]\frac{3x}{4}[/tex] + [tex]\frac{3x}{4}[/tex]

Next step is: 8,500 =  [tex]\frac{3x+3x+3x+4x}{4}[/tex]

                      8,500 = [tex]\frac{13x}{4}[/tex]

                      8,500 × 4 = 13x

                      34,000 = 13x

                      [tex]\frac{34,000}{13}[/tex] = x

                      x = 2,615.38

The son received 2,615.38

Let's get the share of each daughter:

[tex]\frac{3x}{4}[/tex] = [tex]\frac{(3)(2,615.38)}{4}[/tex] = 1,961.54

Each daughter will receive 1,961.54

Let's check: 2,615.38 + 1,961.54 + 1,961.54 + 1,961.54 = 8,500

The diagonal length of the square is 4.243 meters.

square, in geometry, a plane figure with four equal sides and four right (90°) angles.

A square is a special kind of rectangle and a special kind of parallelogram.

The side length of square is 3 meters.

The sides of square are 3 meters because all the sides are same length.

We need to find the diagonal length of the square.

d=√2a

Where d is the diagonal length and a is the length of the square.

d=√2×3

d=1.414×3

d=4.243

Hence, the diagonal length of the square is 4.243 meters.
