Step-by-step explanation:

An = 7 + (41-1)8 = 327

Answer:

327.

Step-by-step explanation:

T41 = a + (n-1) d.

T41 = 7 + ( 41 - 1) 8.

T41 = 7 + ( 40) 8.

T41 = 7 + 320.

T41 = 327.

Answer:

-6/-11

Step-by-step explanation:

First we find the gradient.

Which is defined by the formula, y2-y1/x2-x1

In the coordinates given, y2= -1   y1= 5      x2= -4     x1=7

-1-5/-4-7 = -6.75 (this is the slope / gradient)

Therefore it is -6/-11

Answer:

14. -x-y=-3

    2x-y=6

=> x=3, y=0

Step-by-step explanation:

Answer:

2(x+7) = 2x+14 / 3(x+1) = 3x+3

Step-by-step explanation:

When you  see equations with parenthesis, that means you must do distributive property. So, whatever number is outside of the parenthesis, you multiply it by all the number inside of the parenthsis.

Answer:

6x² + 48x + 42

Step-by-step explanation:

2(x + 7) 3(x + 1) ← multiply the integers

= 6(x + 7)(x + 1) ← expand factors using FOIL

= 6(x² + 8x + 7) ← distribute parenthesis by 6

= 6x² + 48x + 42

Step-by-step explanation:

Example, i have 1 equation and i want to find x

2x - 1 = 5

2x = 5 + 1

2x = 6

x = 6/2

x = 3

So, value of x is 3

Answer:

A) 25. 5 x 5 or 5^2 = 25

B) -4. -2 x -2 or -2^2 = -4

C) 0.25. 0.5 x 0.5 or 0.5^2 = 0.25

Step-by-step explanation:

Answer:

a) x2=5*5=25

b)y2=(-2)*(-2)=4

c)z2=0.5*0.5=0.25

-2/5x - 9 < 9/10

-2/5x-9+9<9/10+9

-2/5x<99/10

(5/-2)*(-2/5 x)<(5/-2)*(99/10)

x>-99/4

Taxable income is a person's gross income minus allowable deductions.

The correct option is B.

As, Any gross income that is used to determine how much tax you owe is referred to as taxable income.

This is equal to your AGI less the total of either your itemized deductions or the standard deduction, whichever is greater, and, if available, the qualifying business income deduction.

So, Taxable income is a person's gross income minus allowable deductions.

Thus, the ideal solution is B.

Answer:

HCF of 12, 24 and 36 by Euclidean Algorithm

As per the Euclidean Algorithm, HCF(X, Y) = HCF(Y, X mod Y)

where X > Y and mod is the modulo operator.

HCF(12, 24, 36) = HCF(HCF(12, 24), 36)

Steps for HCF(12, 24):

HCF(24, 12) = HCF(12, 24 mod 12) = HCF(12, 0)

HCF(12, 0) = 12 (∵ HCF(X, 0) = |X|, where X ≠ 0)

⇒ HCF(12, 24) = 12

⇒ HCF(HCF(12, 24), 36) = HCF(12, 36)

Steps for HCF(12, 36):

HCF(36, 12) = HCF(12, 36 mod 12) = HCF(12, 0)

HCF(12, 0) = 12 (∵ HCF(X, 0) = |X|, where X ≠ 0)

⇒ HCF(12, 36) = 12

Therefore, the value of HCF of 12, 24, and 36 is 12.

Step-by-step explanation:

factors of 12=1,2,3,4,6,12

factors of 24=1,2,3,4,6,8,12,24

factors of 36=1,2,3,4,6,9,12,18,36

common factors =1,2,3,4,6,12

Therefore factors of 12,24,36=12

Answer:

(2xy)³

Step-by-step explanation:

According to the Power Rule of Exponents:

[tex](ab})^{m} = a^{m}b^{m}[/tex]

We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.

8 is a perfect cube of 2:  ⇒  2 × 2 × 2 = 2³ = 8

The cube of x is x³:   ⇒  x × x × x = x³

The cube of y is y³  ⇒  y × y × y  = y³

Hence, we can take the least common factors, (2xy) and raise them to the third power:

(2xy)³ = 2³x³y³ =  8x³y³

Therefore, the correct answer is: (2xy)³

[tex]\\ \sf\longmapsto 8x^3y^3[/tex]

We know the rule of exponents

[tex]\boxed{\sf (ab)^m=a^mb^m}[/tex]

Now

[tex]\\ \sf\longmapsto 8x^3y^3[/tex]

[tex]\\ \sf\longmapsto 2^3x^3y^3[/tex]

[tex]\\ \sf\longmapsto (2xy)^3[/tex]

[tex]\\ \sf\longmapsto (2xy)(2xy)(2xy)[/tex]

Answer:

15N+15J+60

Step-by-step explanation:

We know that Noah and James each receive $15 per hour. That means that to get the money one of them earned in a week, we multiply the money they earn ($15) by the hours they worked (N or J):

15 × N is what Noah earned.

15 × J is what James earned.

Combining those are just 15N + 15J. Then, we add the bonus Noah received ($60) to get their total combined earnings:

15N+15J+60

Answer:

The submarine would be 900 below the ocean surface after 12 minutes assuming it started its descent at the surface of the ocean.

Step-by-step explanation:

The formula for distance traveled (in this case the distance a submarine descends) over a period of time is:

d

=

r

⋅

t

where

d

is the distance traveled (or descended),

r

is the rate of travel and

t

Answer: x = 45

Step-by-step explanation:

Given information

Tina's age (now) = 15 years old

Carl's age (now) = x years old

Ratio of age (3 years ago) = Tina : Carl = 2 : 7

Set equation according to the given information

(15 - 3) / (x - 3) = 2 / 7

Cross multiply

7 (15 - 3) = 2 (x - 3)

Simplify by subtraction in the parentheses

7 (12) = 2 (x - 3)

Simplify by multiplication

84 = 2 (x - 3)

Divide 2 on both sides

84 / 2 = 2 (x - 3) / 2

42 = x - 3

Add 3 on both sides

42 + 3 = x - 3 + 3

[tex]\boxed{x=45}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Answer:

x = 45

Step-by-step explanation:

Let the present age of Carl be x.

Given Tina's present age is 15 and 3 years ago, the ratio of Tina's and Carl's ages was 2:7

Then 3 years ago, Tina's age will be

[tex] \\ 15 - 3 = 12 \: years[/tex]

and, Carl's age will be x - 3

and they are in the ratio 2:7.

therefore,

[tex] \\ \: \: \: \: \: \: \: \: 12 \ratio(x - 3) = 2 \ratio7[/tex]

[tex] \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \frac{12}{x - 3} = \frac{2}{7} [/tex]

[tex] \\ \sf \: by \: cross \: multiplication[/tex]

[tex] \\ \: \: \: \: \: \: 12 \times 7 = 2(x - 3) [/tex]

[tex] \\ \: \: \: \: \: \: x - 3 = \frac{84}{2} = 42[/tex]

[tex] \\ \: \: \: \: \: \: \: \: \: \: \: \: x = 42 + 3[/tex]

Answer:

Option D) d (t ) = -0.25t + 2

Step-by-step explanation:

Given the water level covering a road after a rainstorm of 2 meters, for which the water level recedes at a rate of 0.25 meters per hour:

We can express the depth, d, of the water as a linear function of the time, t, in hours elapsed from the end of the rainstorm as:

d (t ) = -0.25t + 2

The receding rate has a negative value since it represents how the water level decreases over time.

Therefore, the correct answer is Option D: d (t ) = -0.25t + 2

Answer:

4)

Step-by-step explanation:

I think that you meant slope of 9/4. Number 4 would be correct because slope intercept form would be y=mx+b, where m is the slope and b is y intercept. Since b=0, you don't have to add anything, so it would just be y=9/4x

Answer:

4) [tex]y=\frac{9}{4}x[/tex]

Step-by-step explanation:

This is a linear equation in slope-intercept form:

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

1) [tex]y=\frac{9}{4}y[/tex] --- this is just a false equation that cannot be a line.

2) [tex]y=x+\frac{9}{4}[/tex] --- this is a line with a slope of 1 and a y-intercept of 9/4

3) [tex]x=\frac{9}{4}x[/tex] --- this is also false

4) [tex]y=\frac{9}{4}x[/tex] --- this is a line with a slope of 9/4 and a y-intercept of 0.
