The slope and y-intercept of the line is 2 and -7/9 respectively

The formula for calculating the slope intercept form of an equation is expressed as:

y = mx + b

where

m is the slope

b is the y-intercept

Given the equation -18x-9y = 7

Write in slope intercept form

-9y = 18x + 7

y = -18/9 x - 7/9

Compare

m = -2

b = -7/9

Hence the slope and y-intercept of the line is 2 and -7/9 respectively

The number is 280

In mathematics, Least Common Multiple is referred to by its entire name, whereas Highest Common Factor is its complete name. The L.C.M. defines the least number that is exactly divisible by two or more numbers, whereas the H.C.F. describes the biggest factor existing between any given pair of two or more numbers. LCM is also known as the Least Common Multiple (LCM), and HCF is also known as the Greatest Common Factor (GCF).

Two key techniques—the division method and the prime factorization approach—can be used to determine H.C.F. and L.C.M.

So we need to find the LCM of 2,5 and 7. Furthermore, we need to find multiply the LCM with a number which can make its sum of digits equal to 10.

LCM of 2,5 and 7 is 70

70 x 4 = 280

Sum of digits of 280 is 10, which is also less than 500

Answer:

2 is the y-int.

Step-by-step explanation:

Becuase the line runs through the y-axis at 2.

.

3(x+5) + 2(x-3) = 6(3(1/6))

3x + 15 + 2x - 6 = 3 X 1

5x + 9 = 3

5x = - 7

x = - 7/5

we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.

We are given a power set:

A = {1, 2, 3, 4, 5, 6}

We are also given another power set:

B = {2, 3, 4, 5}

We need to tell if B is a subset of A or not.

We can see that every element of B is a part of A as well.

So, we can say that B is a subset of A.

B ⊂ A

{2, 3, 4, 5} ⊂ {1, 2, 3, 4, 5, 6}

Therefore, we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.

104.8cm³(1 decimal place)

Step-by-step explanation:

Volume of a cone is given by the formula

V=1/3πr²h

we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7

V=1/3× 22/7×5²×4

V=1/3 × 22/7 ×25 ×4

V=2200/21

V=104.76190476

The speed of Makayla and Nathan are 12 mph and 20 mph respectively.

Let the speed of Makayla is 'x' mph.

and the speed of Nathan is 'y' mph.

The total distance travelled by both is 129 miles.

The time taken by each is 6 hours, same for both.

Speed  = distance / time

Distance =  speed × time

Makayla's covered distance = xt

Nathan's covered distance = yt

Total distance = xt + yt

xt + yt = 192

As, Nathan travels 8 mph faster than makayla.

The,

y = x + 8, t = 6 hours substitute;

xt + (x+ 8)t = 192

2x + 8 = 192/6

On simplification;

x = 12 mph (Makayla's speed)

Y = x + 8

y = 12 + 8

y = 20 mph (Nathan's speed)

Therefore, the speed of Makayla and Nathan are x = 12 mph and y = 20 mph respective;y.

Brief The Question Please, Thank You

Answer:

  852

Step-by-step explanation:

You want the next number in the pattern that starts with 5, 12, 33, 96, 285.

When looking for patterns in sequences, it is often useful to consider first differences and the relations between them.

  12 -5 = 7

  33 -12 = 21

  96 -33 = 63

  285 -96 = 189

We notice that these differences have a common ratio of 3. This suggests the next difference will be 189×3 = 567.

The next number in sequence is 285 +567 = 852.

__

Additional comment

When differences have a common ratio, an exponential sequence is indicated. These differences have a ratio of 3, but are not powers of 3, so the exponential term needs additional components to completely describe the sequence. We expect there are horizontal and vertical offsets involved.

Exponential regression gives the explicit formula as ...

  y = (3 +7·3^(x-1))/2

If you contribute $400 every quarter for 20 years, the amount of  interest you would  earn during the 20 years is $22,447.52

What future value formula is applicable in this case?

The applicable future value formula is that of an ordinary annuity which determines the future worth of $400 quarterly savings for 20 years bearing in mind that the quarterly interest rate is the annual interest rate divided by 4

FV=PMT*(1+r)^N-1/r

FV=worth of the annuity after 20 years=unknown

PMT=quarterly deposit=$400

r=quarterly interest rate=5%/4=1.25%

N=number of quarterly savings in 20 years=20*4=80

FV=$400*(1+0.0125)^80-1/0.0125

FV=$54,447.52

interest=$54,447.52-($400*80)

interest=$ 22,447.52

A  = p +0.2p

We don't know the value of P, so it stays unknown.

The r is the interest rate as a decimal. we know that r = 0.04 because we're told the interest rate is 4%. Note that 4% = 4/100 = 0.04

The time in years is t = 5

So this means...

A = P + P*r*t

A = P + P*0.04*t ... replace r with 0.04

A = P + P*0.04*5 ... replace t with 5

A = P + P*0.2 ... multiply

A = P + 0.2*P ... swap term

A  = p +0.2p
