Answer: The product of x and 5 is 5x

Answer:

m> 55 (you only flip the direction of the sign when you divide by a negative number)

Step-by-step explanation:

Answer:

m > 55

Step-by-step explanation:

simplify both sides of the inequality

m - 19 > 36

Add 19 to both sides

36+19

m>55

Answer: y^3 - 6y^2 + 5y

Step-by-step explanation: You start by rewriting the expression y^3- 5y^2/y +(y-1)

Then you factor out y(y^2-5y)/y *(y-1)

Then you reduce the fraction which cancels the 2 y’s out (y^2-5y)(y-1)

Then you multiple the 2 parentheses which equals y^3-y^2-5y^2+5y

Then you simply the answer you got which comes out to y^3-6y^2+5y

P.s. ^2, ^3, etc. are the exponents.

Answer:

Yes, they have the same slope

Step-by-step explanation:

Both y=2 and y=-4 have the same slope, a slope of zero, because when they are graphed, both of them form a straight horizontal line. And since they both form a straight horizontal line, they are parallel because they have the same slope.

Answer:

8

Step-by-step explanation:

Given the expression

4t^6-r^10 we are to factorize in the form;

(2t^x+r^y)(2t^x-r^y)

First we need to factorize (2t^x+r^y)(2t^x-r^y)

[tex]= (2t^x+r^y)(2t^x-r^y)\\= 4t^{2x}-2t^xr^y + 2t^xr^y - r^{2y}\\= 4t^{2x}-r^{2y}[/tex]

Compare [tex]4t^{2x}-r^{2y} \ with \ 4t^6-r^{10}[/tex]

[tex]4t^{2x} = 4t^6\\t^{2x} = t^6\\equate \ the \ powers\\2x = 6\\x = 3\\[/tex]

Get y;

[tex]r^{2y} = r^{10}\\2y = 10\\y = 5\\Hence \ x + y = 3+5 = 8[/tex]

Hence the sum of x and y is 8

Answer:

(2,0) or 2

Step-by-step explanation:

The x-intercept is the point where the line intercepts or goes through the x-axis. The x-axis is the horizontal line that is labeled x.

Another way to find the x-intercept is to find the x value when the y value or f(x) equals zero.  

Answer: 461.6 ft^3

Step-by-step explanation:

Substitute r and h into the volume formula. In this case, the height is 12, so h = 12. The diameter is 7, so the radius is half that, or 3.5. Substitute into the formula and simplify:  V=π(3.5)2(12)V=π(12.25)(12)V=147π

So the exact volume of the cylinder is 147π ft3

.

To find the approximate volume, substitute 3.14 for π

and simplify:V≈147(3.14)≈461.58

. Rounded to the nearest tenth, the approximate volume of the cylinder is 461.6 ft3

.

Answer:

The input (x) = 4

Step-by-step explanation:

Since we know what the output (y) is, you can substitute it into the equation to get:

5 = 3x - 7  

Then, solve for x, and you’ll get x = 4. The image below shows step-by-step on how to solve for x.

Answer:

If y = 290, x = 30

Step-by-step explanation:

y = 200 + 3x   If y = 290

290 = 200 + 3x

290 - 200 = 3x

90 = 3x

90/3 = x

30 = x

Answer:

Option (C)

Step-by-step explanation:

Let the relation between amount of money (m) and Time (t) is represented by the equation,

m = ct + b

Where c = Investment per week

b = Ben already had the amount before investment

From the question,

c = $5 per week

b = $100

Therefore, equation will be,

m = 5t + 100

If duration of the investment 't' = 8 weeks

Amount in the account after 8 weeks,

m = 5(8) + 100

m = $140

Option (C) is the correct option.

Answer:

7 cups + 3 litres = 9.8 pints

⇒ Equation 1

5 litres - 9 cups = 6 pints

⇒ Equation 2

Relationship between cups and

Rearranging equation 1 to make pints the subject

⇒ substitute this into Equation 2

Hence, 1 litre = 2.1 cups

Relationship between cups and pints

Rearrange equation 1 to make litres the subject

⇒ Substituting this into Equation 2

Hence, 1 pint = 2 cups

Relationship between pints and liter

Rearranging equation 1 to make cup the subject

⇒ subsitute this into equation 2

Hence, 1 liter = 2.1 pints
