Answer: 15x-14y=22

3x+5y=7

2.5x-y=17

42x+0.4y=15

Step-by-step explanation:

The standard linear equation of two variables x and y is given by :-

Ax +By = C , where A is a positive integers,  and B, and C are integers.

Therefore, from the given options the linear equations that are in standard form are

15x-14y=22

3x+5y=7

2.5x-y=17

42x+0.4y=15

[-2x+8y=14 is not in standard form ∵ -2 is a negative integer.]

Answer:

351

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] p - 3 = 114 ( multiply through by 3 to clear the fraction )

p - 9 = 342 ( add 9 to both sides )

p = 351

Answer:

Graph G

Step-by-step explanation:

The graphs are attached

Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours, hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour

Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per secong

The slope (rate of change) of a line (m) is given by:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:

[tex]Slope\ of\ line\ F=\frac{-20-0}{10-0} =-2\ meters\ per\ second[/tex]

b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:

[tex]Slope\ of\ line\ G=\frac{-70-0}{10-0} =-7\ meters\ per\ second[/tex]

c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:

[tex]Slope\ of\ line\ H=\frac{-35-0}{10-0} =-3.5\ meters\ per\ second[/tex]

d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:

[tex]Slope\ of\ line\ j=\frac{-3.5-(-3.5)}{10-0} =0\ meters\ per\ second[/tex]

Answer:The answer is H , It is the graph where -10 is right below the 0 on the y.

Step-by-step explanation:

Opposite to the angle = Pole

Adjacent to the angle = Shadow

Therefore tan50° = 18ft/x,

x = 18ft / tan50° = 15.1ft.

Answer:

No of white balls = 5

Step-by-step explanation:

Given that,

Total no of red balls = 4

Total no of green balls = 6

The probability of not drawing a white ball in one draw be, [tex]P=\dfrac{2}{3}[/tex]

We need to find the number of white balls. Let there are x balls.

The probability of drawing a white ball = 1 - the probability of not drawing a white ball

= 1 -2/3

= 1/3

Using the formula for solving probability of having a white ball.

[tex]P=\dfrac{\text{favorable outcome}}{\text{total no of outcomes}}\\\\\dfrac{1}{3}=\dfrac{x}{4+6+x}\\\\\dfrac{1}{3}=\dfrac{x}{10+x}\\\\10+x=3x\\\\10=2x\\\\x=5[/tex]

Hence, there are 5 white balls.

Answer:

  6

Step-by-step explanation:

The value of b that makes the two lines identical is the opposite of the y-intercept of the line.

  y = 6x -6 . . . . has y-intercept = -6

The value of b is the number in the term -6, so is 6.

but just do this $27.30

so x is $27.30

Answer:

Height h = 9 cm

Step-by-step explanation:

Given:

Surface area of cuboid = 102 cm²

Length l = 2 cm

Breadth b = 3 cm

Find:

Height h

Computation:

Surface area of cuboid = 2[lb + bh + hl]

102 = 2[(2)(3) + (3)(h) + (h)(2)]

51 = 6 + 3h + 2h

45 = 5h

Height h = 9 cm

Answer: 9 cm

I win and im the brainlest.

Answer:

a. The function is a decay function

b. The function is f(n) = 33500 [tex](0.975)^{n}[/tex]

c. The population in the year 2025 is 31,800 to the nearest hundred

Step-by-step explanation:

The form exponential growth function is y = a [tex](1+r)^{x}[/tex] , where

The form exponential decay function is y = a [tex](1-r)^{x}[/tex] , where

∵ In 1995, the population of a town was 33,500

∴ a = 33,500

∵ It is decreasing at a rate of 2.5% per decade

→ The decrease means, it is a decay function, then use the 2nd form above

∴ f(n) = a [tex](1-r)^{n}[/tex] , where f(n) is the population in n decades

∴ It is a decay function

a. The function is a decay function

∵ The rate is 2.5% per decade ⇒ 2.5% each 10 years

∴ r = 2.5%

→ Divide it by 100 to change it to decimal

∵ 2.5% = 2.5 ÷ 100 = 0.025

∴ r = 0.025

→ Substitute the values of a and r in the f(n)

∴ f(n) = 33500 [tex](1-0.025)^{n}[/tex]

∴ f(n) = 33500 [tex](0.975)^{n}[/tex]

b. The function is f(n) = 33500 [tex](0.975)^{n}[/tex]

∵ We need to find the population in 2025

→ Find how many decades from 1995 to 2025

∵ There are 20 years from 1995 to 2025

∵ 1 decade = 10 years

∵ n is the number of decads

∴ n = 2 ⇒ (20/10 = 2)

→ Substitute n in the function by 2

∵ f(2) = 33500 [tex](0.975)^{2}[/tex]

∴ f(2) = 31845.9375

→ Round it to the nearest hundred

∴ f(2) = 31800

c. The population in the year 2025 is 31,800 to the nearest hundred

Answer:

She needs to have $694,700 in her account

Step-by-step explanation:

Here, we want to know the amount that should be in Sally’s account on that day she turns 64

Firstly, we need to know the difference between the ages of 64 and 83

The difference between these ages are 83-64 = 19

So, she intends receiving $9,500 per month for 19 years

The number of months in 19 years is 19 * 12 = 228 months

So, the total amount of money she needs is 228 * 9,500 = $2,166,000

Now, we have an interest that would be compounded but in this case, we already have the amount needed but what we need is the principal to be compounded in this case

The formula for compound interest here is;

A = P( 1 + r/n)^nt

where A is the amount which is 2,166,000

P is ?

r is the interest rate = 6% = 6/100 = 0.06

n is the number of times we are compounding in a year; since it is monthly, that would be 12 times in a year

t is the number of years which is 19 in this case

Substituting all values, we have that;

2,166,000 = P( 1 + 0.06/12)^(12*19)

2,166,000 = P(1.005)^(228)

P = 2,166,000/(1.005)^228

P = $694,699

This rounded to a whole dollar is P = $694,700

The correct answer is Option A
