Answer:1

Step-by-step explanation:the y is a place holder instead of the digit 1 because there is only one y. Whitch is the same reason why the 2 isn’t 2x because the 2 is a place holder for how many x there are. The problem is showing you how much value each place holders have. (x,y)

Answer:

Step-by-step explanation:

we will use first the distributive property and multiply

45+ 5a<110

subtract 45 from both sides

5a<110-45

5a<65 we divide by 5

a<13

Answer:

-x²+3x-8

Step-by-step explanation:

Given polynomials are :

f(x) = (x+2)²

p(x) = 7x−4

We need to find a simplified polynomial when f(x) is subtracted from p(x) i.e.

p(x) - f(x) = 7x−4 - (x+2)²

We know that, (a+b)² = a²+b²+2ab

So,

p(x) - f(x) = 7x−4 -(x²+2²+2(x)(2))

= 7x−4 -(x²+4+4x)

= 7x−4-x²-4-4x

= -x²+3x-8

Hence, the result will be -x²+3x-8.

Answer:

The system of equations =

25 + 0.05x = 12 + 0.09x

The number of stickers where the cost of both printers to be equal is 325 stickers

Step-by-step explanation:

Let the number of stickers = x

Printer 1

Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.

$25 + $0.05× x

25 + 0.05x

Printer 2

Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.

$12 + $0.09 × x

12 + 0.09x

We equate both equations together

The system of equations =

25 + 0.05x = 12 + 0.09x

Collect like terms

25 - 12 = 0.09x - 0.05x

13 = 0.04x

x = 13/0.04

x = 325 stickers

Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers

Answer:

x = 1

Step-by-step explanation:

x - 2 = -3x + 2

you can do any one of these 4 steps first and still get the same answer:

a) subtract x from each side

b) add 2 to each side

c) add 3x to each side

d) subtract 2 from each side

after doing one of the above you will have a two-step equation and must undo addition or subtraction before undoing multiplication or division

Answer:

c = 40 + 0.79m

Step-by-step explanation:

The base cost is $40.

So we have:

c = 40

Then, since an additional $0.79 is charged for every mile driven, we add:

+ 0.79m

So then our equation is:

c = 40 + 0.79m

where c = total cost

and m = number of miles driven

Answer:

The width of a rectangle is: w = x+3

Step-by-step explanation:

Given

The length of rectangle = l = 4x

The area of rectangle = A = 4x² + 12x

To determine

The width of rectangle = w = ?

We know that the formula of the area of the rectangle is

[tex]A = wl[/tex]

substitute A = 4x² + 12x and l = 4x in the equation to determine the width w of the rectangle

4x² + 12x = w×4x

w = [4x² + 12x] / [4x]

Factor 4x² + 12x:   4x(x+3)

w = [ 4x(x+3) ] /  [4x]

w = x+3

Therefore, the width of a rectangle is: w = x+3

Answer:

10:50

Step-by-step explanation:

Answer:

$10.50 for 10 miles & 0.75m+3 for "m" miles

Step-by-step explanation:

if the taxi charges $3 just for showing up, then in the formula (y=mx+b) 3 would be your "b"

y = mx + 3

if the taxi is charging $0.75 per mile, the mile will be your "x" in the formula, and 0.75 will represent your "m" in the formula

y = 0.75x + 3                 - this is your equation for "m" miles

to find how much for 10 miles, substitute 10 for "x" in your formula

y = 0.75 (10) +3

y = 10.50

so it is $10.50 for 10 miles, including the 3 dollar pick up fee.

Step-by-step explanation:

5x² + kx - 3 = 0 has a root x = 1.

=> 5(1)² + (1)k - 3 = 0

=> 5 + k - 3 = 0

=> k = -2.

Therefore we have 5x² - 2x - 3 = 0.

=> (x - 1)(5x + 3) = 0

=> x = 1 or x = -3/5.

Hence the other root is -3/5.

Answer: 3.5 meters

Step-by-step explanation:

First and foremost, we need to note that 1000 millimeters = 1 meter. Therefore, for us to convert 3500 millimeter to meters, we have to divide it by 1000. This will be:

= 3500/1000

= 3.5 meters

The required reference angle of angle 192 is 12. OPtion C is correct.

Given that,
An angle of 192°
Reference angle to be determined.

The angle can be defined as the one line inclined over another line.
Angel over angle is of 360° and angle over line is 180°

The function in mathematics to operate and diagnose the function to make the function simple or more coherent is called simplifying and the process is called simplification.

Since in the question, An angle is given of 192° its corresponding and relatable angle is to be determined.

Here, a standard measure of an angle is 180, So let the reference angle b x, for reference angle the angle must be more or less than 180. So,

x = 192 - 180
x = 12

Thus, the required reference angle of angle 192 is 12. Option C is correct.

Answer: y = 1

Step-by-step explanation: Lets solve for y, step by step!

6 = 2(y + 2)

6 = ( 2 x y + 2 x 2)

6 = 2y + 4

2y + 4 = 6

2y + 4 - 4 = 6 - 4

2y = 2

Answer:

[tex]\sqrt{57}[/tex] or 7.54983

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

2,400 = 7,500[tex](10)^{x}[/tex]

First of all, you want to isolate the [tex](10)^{x}[/tex] by dividing each side by 7,500.

After doing this, you will get

[tex]\frac{2400}{7500}[/tex] = [tex](10)^{-x}[/tex].

Putting this in the logarithmic form, you get [tex]log_{10}[/tex] [tex]\frac{2400}{7500}[/tex] = - x

To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get  [tex]-log_{10} \frac{2400}{7500}[/tex] = x.

When you simplify 2400/7500, you get 8/25, so the answer is B.

Hope this helps!

Answer:

An equation relating x and y is:

y = 3/4x - 5.5

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given the points

(2, -4), (x, y), A(6, -1), and B(10, 2)

Taking any two points let say A(6, -1), and B(10, 2) to determine the slope

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

[tex]\left(x_1,\:y_1\right)=\left(6,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:2\right)[/tex]

[tex]m=\frac{2-\left(-1\right)}{10-6}[/tex]

Refine

[tex]m=\frac{3}{4}[/tex]

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = -5.5

Thus, the y-intercept b = -5.5

Thus, substituting b = -5.5 and m = 3/4 in the slope-intercept form of the line equation

y = mx+b

y = 3/4x + (-5.5)

y = 3/4x - 5.5

Therefore, an equation relating x and y is:

y = 3/4x - 5.5

Answer:

3.38pi

Step-by-step explanation:

Using simple math and the equation for finding the volume of a sphere, we can see that by taking the height of 10, and the volume of 30, that with that information we can deduce that the radius of the cone would be 1.69pi. With this information, we know the radius is half of the diameter. Therefore, we multiply 1.69 by 2, to get our end result, 3.36pi
