Answer:

[tex]m = - \frac{3}{5}[/tex]

Step-by-step explanation:

The slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2.

Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

Given,

The line passes through the points (-3,1) and (2,-2)

We have,

x₁ = -3, y₁ = 1

x₂ = 2, y₂ = -2

∵ Slope m = (y₂ - y₁)/(x₂ -x₁  )

Substitute the above values in the formula, and we get

The slope of the line = (-2 - 1) / (2 - (-3))

The slope of the line = (-2 - 1) / (2 +3)

The slope of the line = -3/5

Thus, the slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).

Answer:

1. 1.1 times the weight of the puppy

2. 11/10

3. %110

Step-by-step explanation:

11 x 9 = 99

99/90=1.1

1.1 = 11/10 = %110

1.1 = 11/10 = %110

Step-by-step explanation:

Given:

[tex]\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]

To find:

The missing value.

Solution:

Let x be the missing value.

We have,

[tex]\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]

[tex]\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}[/tex]

Subtract [tex]\dfrac{9}{10}[/tex] from both sides.

[tex]\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{15-9}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{6}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{3}{5}[/tex]

Multiplying both sides by 5, we get

[tex]x=3[/tex]

So, the missing value is 3.

Therefore, the correct option is C.

Answer:

The polynomials are:

[tex]\frac{2}{3}[/tex] x² + x + 1 ⇒ C

x³ + 2x +√2 ⇒ E

Step-by-step explanation:

A polynomial: is an expression consisting of variables and coefficients, with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

Let us solve the question

∵ The polynomial never division by a variable

∵ Answer A and B have a division in variable ⇒ ( [tex]\frac{1}{x^{2}+1 }[/tex] , [tex]\frac{2}{x^{3}}[/tex] )

∴ Answers A and B are not polynomials

∵ The polynomial has integer exponents of variables

∵ Answer D has a fraction exponent of x ⇒ [tex]x^{\frac{2}{3}}[/tex]

∴ Answer D is not a polynomial

∵  [tex]\frac{2}{3}[/tex] x² + x + 1 has a non-negative integer exponent of x

∵ There is no division by x

∴  [tex]\frac{2}{3}[/tex] x² + x + 1 is a polynomial

∵ x³ + 2x +√2 has a non-negative integer exponent of x

∵ There is no division by x

∴ x³ + 2x +√2 is a polynomial

∴ The polynomials are [tex]\frac{2}{3}[/tex] x² + x + 1 and x³ + 2x +√2

Answer:

103.125

Step-by-step explanation:

110.00 times 15% = 16.5

16.5 times 6.25% = 103.125

Answer - 103.125

Answer:

With the coupon and sales tax, the bicycle costs $100.38.

Step-by-step explanation:

First, we need to find 6.25% of $110.

110 x 0.0625 = 6.88

Now, let's add this to the total, or $110.

110 + 6.88 = $116.88

After that, we need to find 15% of this total.

116.88 x 0.15 = 17.53

Now, we need to subtract this from the total, which is now $116.88.

116.88 - 16.5 = $100.38

Now, with the coupon and sales tax, the bicycle costs $100.38.

Hope this helps! :D

Answer:

14. -g + 10, 15. 12k + 3

Step-by-step explanation:

I'm assuming you want to simplify the equation. For 14, we distribute -2. This gets us -2g + 10 + g. We can simplify that to -g + 10. We can't simplify that, so our answer is complete. For 15, we combine 8k and 4k to get 12k + 3. That can't be simplified, so we are done.

Answer:

The constant of variation is 2

Step-by-step explanation:

The equation of the direct variation is y = k x, where k is the constant of variation

Let us solve the question

∵ x and y are in the direct variation

→ Use the form of the equation above

∴ The equation of variation is y = k x

∵ x = 3

∵ y = 6

→ Substitute them in the equation above

∴ 6 = k (3)

∴ 6 = 3k

→ To find k divide both sides by 3

∵ [tex]\frac{6}{3}[/tex] = [tex]\frac{3k}{3}[/tex]

∴ 2 = k

∵ k is the constant of variation

∴ The constant of variation is 2

Answer:  [tex]\frac{8x^3}{27y^6}[/tex]

This is the fraction 8x^3 all over 27y^6

On a keyboard, we can write it as (8x^3)/(27y^6)

===========================================================

Explanation:

The exponent tells you how many copies of the base to multiply with itself.

We'll have three copies of [tex]\left(\frac{2x}{3y^2}\right)[/tex] multiplied with itself due to the cube exponent on the outside.

So,

[tex]\left(\frac{2x}{3y^2}\right)^3 = \left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2x*2x*2x}{(3y^2)*(3y^2)*(3y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{(2*2*2)*(x*x*x)}{(3*3*3)*(y^2*y^2*y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{9y^6}\\\\[/tex]

-------------------

Or another approach you could take is to cube each component of the fraction. The rule I'm referring to is [tex]\left(\frac{a}{b}\right)^c = \frac{a^c}{b^c}[/tex]

Applying that rule will lead to:

[tex]\left(\frac{2x}{3y^2}\right)^3 = \frac{(2x)^3}{(3y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2^3*x^3}{3^3*(y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^{2*3}}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^6}\\\\[/tex]

Either way you should get 8x^3 all over 27y^6 as one fraction.

Answer:

5x + 2y = 250 pencils

Step-by-step explanation:

5 represents the amount in each small box.

2 represents the amount in each large box.

Therefore once you multiply by 5 and x, then multiply by 2 and y you should get the total amount of pencils for the pencils in small boxes and the amount for large sepretally. Then you'd add both of the digits to get the total pencils in all

Answer:

[H^+] = Antilog[-6]

Step-by-step explanation:

Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.

pH=−log[logH^+]

-pH = log[H^+]

[H^+] = Antilog[-pH]

Since pH =6

The equation is;

[H^+] = Antilog[-6]

Answer:

logH=−6

Step-by-step explanation:

Substituting the given value into the formula: 6=−logH; −6=logH; 10−6=H; H=0.000001. The equation logH=−6 is a step in the process of finding the H value.
