ANSWER: 11

Answer:

Step-by-step explanation:

We need to convert function to slope-intrcept form y=mx+b, where:

3x - 5y = 15​           {subtract 3x from both sides by 20}

-5y = -3x + 15                    {divide both sides by (-5)}

y = 3/5x - 5     ⇒   b = -5

Therefore y-intercept of the line is (0, -5)

Answer:

1.75n

Step-by-step explanation:

First we should just ignore the 'n' in '4n' for now.

So we have 7 and 4 left.

Now we would do 7/4=1.75

Now, we just add on the 'n' to 1.75 and we would get 1.75n

Hope this helps! :)

Answer:

Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers. This should help you.

Step-by-step explanation:

The statement describes values of x and y such that could be an irrational numbers, the value of x is the square root of an integer, and the value of y is an integer greater than zero.

We have given that the value of x and y,

such that could be an irrational number.

An irrational number, any real number that cannot be expressed as the quotient of two integers.

Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers.

Therefore we can conclude that

The statement  A, C, or D do not show the irrational numbers

because they all are stated as integers,

which cannot be irrational.

Therefore option B is correct.

The value of x is the square root of an integer, and the value of y is an integer greater than zero.

Answer:

Step-by-step explanation:

Pretty Tall.

Tan(72) = opposite / adjacent

The opposite is the height of the building

The adjacent = 100

Tan 72 = 3.077

Tan (72) = opposite / 100

3.077 = opposite / 100                   Multiply by 100

3.077 * 100 = opposite

opposite = 307.7

opposite rounded = 308

Answer: 33 mph

Step-by-step explanation:

First find out what 40% of 55 is:

= 40% * 55

= 22 mph

This means that the speed reduces by 22 mph inside the city.

The speed inside the city is therefore:

= 55 - 22

= 33 mph

Answer:

x = 88.333

Step-by-step explanation:

Octagon = 1080 degrees

1080 = 2x + x + 143 + 152 + 116 + 125 + 140 + 139 (Clean up the problem)

1080 - 815 = 3x

265 = 3x (Divide each side by 3)

x = 88.333

Answer:

The zeros are the points on the x-axis where the graph intersects.

For factorization, you do (x - the zero) for each zero, and multiply them together.

7. A. The zeros are -2 and 4.

The factorization is (x + 2)(x - 4)

7 B. The zeros are 1 and 3.

The factorization is (x - 1)(x - 3)

y = (x - 2)(x - 3)

Step-by-step explanation:

Step-by-step explanation:

When lines are perpendicular to each other

multiplying their gradients(m) will equal to - 1

so , m1 × m2 = -1

1st:Find m1

5x+6y= -6

make y the subject,

6y= -5x -6

[tex]y = \frac{ - 5x - 6}{6} [/tex]

y= -5/6x - 1

because y = mx + c

m1 = -5/6

2nd:find m2

-5/6 × m2 = -1

m2 = 6/5

3rd: substitute m2 and the coordinates into y=mx+c

y=mx+c

-1= (6/5)(-2)+c

-1 = -12/5 + c

-5 = -12 + c

-5+12= c

c = 7

4th: substitute m2 and c into y= mx+c to find the equation the line

y =6/5x + 7 (Ans)

As per slope-intercept form, the equation of the line through point (−2,−1) and perpendicular to 5x + 6y = -6 is 5y = 6x + 7.

The slope-intercept form of a straight line is y = mx + c.

Here, 'm' is the slope and 'c' ix the y-intercept of the given line.

The given equation is 5x + 6y = - 6

Therefore, in slope-intercept form, this equation will be:

y = - 5x/6 - 1

Therefore, the slope of this line is m = - 5/6 and the y-intercept is c = - 1.

The required line is perpendicular to the given line.

Therefore, the slope of the required line is

= - 1/m

= 6/5

Again, the required line passes through the point (- 2, - 1).

Therefore, - 1 = - 2(6/5) + c

⇒ c = - 1 + 12/5

⇒ c = 7/5

The equation of the required line is

y = (6/5)x + 7/5

⇒ 5y = 6x + 7

Answer:

0 visits

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Rewards for signing up = 80 points

Reward per visit = 2.5 points

Total points needed = 105

Let, number of visits = x

So, we can calculate number of visits by using following formula,

80 + (2.5 × X) = 105

2.5X = 105 - 80

2.5X = 25

X = 25 ÷ 2.5

X = 10 visits.
