Answer:

y = 250x + 1500

Step-by-step explanation:

y = mx + b

y = 3000

m = 250

x = 6

3000 = 250(6) + b

Multiply.

3000 = 1500 + b

Subtract.

1500 = b

Answer: Hence, Mean height of the girls is: 1.48

Step-by-step explanation: It is given that:

in a class of 32 students .

the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.

Since there are 14 boys in a class.

So, number of girls is equal to (32-14)=18.

The mean height of 14 boys is 1.56.

Hence the sum of height of 14 boys is= 1.56×14=21.84

Similarly mean height of 32 students is 1.515.

Hence, sum of height of 32 students=1.515×32=48.48.

Let x denote the mean height of 18 girls.

Hence, sum of height of 18 girls is: 18 x.

Now,

18x+21.84=48.48

( since sum of height of girls and boys is equal to the sum of height of all the students)

so, 18x=48.48-21.84

18 x=26.64

Hence, x=1.48

Hence, Mean height of the girls is: 1.48

Answer:

19

Step-by-step explanation:

Given the polynomial :

x2 + bx + 18 ;

The polynomial Given is if degree 2 ;

The equation can be solved using the quadratic function degree 2 to check which of the options given can be factored :

Here,

a = 1 ; b =? c = 18

Checking each option :

If b = 17

x2 + 17x + 18 = 0

x2 + 17x + x + 18 = 0

(x + 17)(x + 1)

If b = - 19

(x-1)(x-18)=0

Answer: 11/12

Step-by-step explanation:

Answer:

Y=2x+0

Step-by-step explanation:

First you have to find the slope of the graph or the rise over run, which in this case is 2

Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.

To double check our work take a random point on x axis. I chose the point 1,2

fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct

Step-by-step explanation:

Graph y-2x=0

y−2x=0

Add 2x to both sides of the equation.

y=2x

Use the slope-intercept form to find the slope and y-intercept.

Slope: 2y-intercept: 0

Any line can be graphed using two points.

Answer:

Its D

Step-by-step explanation:

The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be 00 or 11. In this case, The degree of f(x)=x5−10f(x)=x5-10 is 11, which makes the function a linear function.

f(x)=x5−10f(x)=x5-10 is a linear function

meaning the reciprocal of 367 is 1 divided by 367 which is: 0.00272479564

Answer:

Distributive property.

Step-by-step explanation:

A distributive property is a rule that states that, multiplying two factors such as a binomial and trinomial would give the same result as multiplying the sum of two addends by the other factor.

Hence, the distributive property is used to simplify the product of a binomial and trinomial.

For example, let's find the product of (2x + 4)(5x² + 3x + 10)

First of all, we would distribute trinomial into each of the term in the binomial.

2x(5x² + 3x + 10) + 4(5x² + 3x + 10)

Distributing the monomial into the trinomial, we have;

2x(5x²) + 2x(3x) + 2(10) + 4(5x²) + 4x(3x) + 4(10)

Expanding the bracket, we have;

10x³ + 6x² + 10 + 20x² + 12x² + 40

Collecting like terms, we have;

10x³ + (6x² + 20x² + 12x²) + 10 + 40

10x³ + 38x² + 50

Therefore, (2x + 4)(5x² + 3x + 10) = 10x³ + 38x² + 50

Answer:

40/100 X 150 = 60

new garden will be 60ft

The length of the new garden is 60 feet.

A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."

Given:

On their farm, Doug and Elizabeth created a garden.

They wish to increase its dimensions by 50% without changing the shape of the garden.

If the length of the garden is now 40 feet long.

Then increased by 50% means,

100 + 50 = 150%.

In decimals,

150% = 1.5

The length of the new garden is,

= 40 x 1.5

= 60 feet.

Therefore, the length is 60 feet.

The centroid is the point of concurrency of gravity in a triangle.

The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians converge.

Since, the center of the gravity of the triangle is a point where a triangle is totally balanced.

The point of concurrency of the center of gravity of a triangle is a point where all three medians meet, and this point is called centroid.

Hence, centroid is the point of concurrency of gravity in a triangle.
