Step-by-step explanation:

I dont have time to explain de but thats the answer

Answer:

y = - 2x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3 ) and (x₂, y₂ ) = (1, 1 )

m = [tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = - 2x + 3 ← equation of line

The option that represents the answers for 6, 8, 10, and 14 is the second option-   31, 41, 51, 71

From the question, we are to determine the option that represents the answer for pictures 6, 8, 10, and 14

In the given diagram,

The first picture requires 6 matches

The 2nd picture requires additional 5 matches

the 3rd  picture requires additional 5 matches

and so on

That is

1 → 6

2 → 6 + 5 = 11

3 → 11 + 5 = 16

4 → 16 + 5 = 21

5 → 21 + 5 = 26

6 → 26 + 5 = 31

7 → 31 + 5 = 36

8 → 36 + 5 = 41

9 → 41 + 5 = 46

10 → 46 + 5 = 51

11 → 51 + 5 = 56

12 → 56 + 5 = 61

13 → 61 + 5 = 66

14 → 66 + 5 = 71

Hence, the option that represents the answers for 6, 8, 10, and 14 is the second option-   31, 41, 51, 71

Answer:

j fingertip was not an easy choice but

Answer:

Step-by-step explanation:

The rectangle's area decreased by 19%.

Length = L

Breadth = B

Original area = L x B

New area = A = L x (1 + 25%) x B x (1 - 25%)

A = L x B x 0.25 x 0.75 = L x B x 1.05

Therefore the area of the rectangle has decreased by 19%.

To find the location of a rectangle, multiply its width by means of its height. If we understand the sides of the rectangle which are different lengths, then we have each the height and the width.

The perimeter P of a rectangle is given through the system, P=2l+2w, wherein l is the period and w is the width of the rectangle. The area A of a rectangle is given by means of the method, A=lw, in which l is the duration and w is the width.

Any questions you may ask.

Answer:

x = 1

Explanation:

[tex]\sf \rightarrow log(3x) + log(x + 4) = log(15)[/tex]

Rule: log(a) + log(b) = log(ab)

[tex]\sf \rightarrow log(3x(x + 4)) = log(15)[/tex]

cancel out log on both sides

[tex]\sf \rightarrow 3x(x + 4) = 15[/tex]

relocate constant variable

[tex]\sf \rightarrow 3x^2 + 12x -15 = 0[/tex]

take 3 as a common factor

[tex]\sf \rightarrow 3(x^2 + 4x -5) = 0[/tex]

divide both sides by 3

[tex]\sf \rightarrow x^2 + 4x -5 = 0[/tex]

middle term split

[tex]\sf \rightarrow x^2 + 5x -x-5 = 0[/tex]

factor common terms

[tex]\sf \rightarrow x(x + 5) -1(x+5)= 0[/tex]

collect into groups

[tex]\sf \rightarrow (x-1)(x+5)= 0[/tex]

set to zero

[tex]\sf \rightarrow x-1 = 0 , \ x+5= 0[/tex]

relocate variables

[tex]\sf \rightarrow x = 1, \ x = -5[/tex]

There must be a positive solution for log, so the solution is only x = 1

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

Given:

[tex]\log (3x)+\log(x+4)=\log (15)[/tex]

As the logs have no base, assume that the base is 10.

[tex]\textsf{Apply log Product law}: \quad \log_ax + \log_ay=\log_axy[/tex]

[tex]\implies \log_{10} (3x)+\log_{10}(x+4)=\log_{10} (15)[/tex]

[tex]\implies \log_{10} \left(3x(x+4)\right)=\log_{10} (15)[/tex]

Expand the brackets:

[tex]\implies \log_{10} \left(3x^2+12x\right)=\log_{10} (15)[/tex]

[tex]\textsf{Apply the log Equality law}: \quad \textsf{if }\: \log_ax=\log_ay\:\textsf{ then }\:x=y[/tex]

[tex]\implies 3x^2+12x=15[/tex]

Subtract 15 from both sides:

[tex]\implies 3x^2+12x-15=0[/tex]

Factor out the common term 3:

[tex]\implies 3(x^2+4x-5)=0[/tex]

Divide both sides by 3:

[tex]\implies x^2+4x-5=0[/tex]

Split the middle term:

[tex]\implies x^2+5x-x-5=0[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies x(x+5)-1(x+5)=0[/tex]

Factor out the common term (x + 5):

[tex]\implies (x-1)(x+5)=0[/tex]

Therefore:

[tex]x-1=0 \implies x=1[/tex]

[tex]x+5=0 \implies x=-5[/tex]

As logs cannot be taken of negative numbers, [tex]x=-5[/tex] is an extraneous solution.  Therefore, the only valid solution is:  [tex]x=1[/tex]

Answer:

[tex]y=\frac{-2}{3} x-15[/tex]

Step-by-step explanation:

First draw a line. I will put it in an attachment so you can see the line.

Now choose to points on the line to use the slope formula.

(0,15) and (3,13).

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Plug in the information needed using the two points chosen.

[tex]\frac{13-15}{3-0}=\frac{-2}{3}[/tex]

The slope is [tex]\frac{-2}{3}[/tex].

Now use point-slope formula.

Point-slope formula: y-y1=m(x-x1)

y-15=[tex]\frac{-2}{3}[/tex](x-0)

y-15=[tex]\frac{-2}{3}[/tex]x-0

Subtract 15 from both sides.

y=[tex]\frac{-2}{3}[/tex]x-15

Using the mid-point concept, the set of points that has midpoint B(-41,23) is: G(10,10) and H(-92,36).

The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.

In this problem, we have that:

Hello !

Answer:

Step-by-step explanation:

Pythagorean Theorem : a² + b² = c² ⇔ b² = c² - a²

Here, we have a = 4 and c = 6 so :

    b² = 6² - 4²

⇔ b² = 36 - 16

⇔b² = 20

⇔ b = √20  (and not b= -√20 because b ≥ 0)

Answer:

b = [tex]\sqrt{20}[/tex]

Step-by-step explanation:

Using the Pythagorean Theorem:

6² = 4² + b²

⇒ b² = 6² - 4²

⇒ b = [tex]\sqrt{6^2 - 4^2}[/tex]

⇒ b = [tex]\sqrt{36 - 16}[/tex]

⇒ b = [tex]\sqrt{20}[/tex]

Step-by-step explanation:

the equation of parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier.

here (h, k ) = (3, 1 ) , then

y = a(x - 3)² + 1

to find a substitute any other point on the graph into the equation.

using (0, 7 )

7 = a(0 - 3)² + 1 ( subtract 1 from both sides )

6 = a(- 3)² = 9a ( divide both sides by 9 )

[tex]\frac{6}{9}[/tex] = [tex]\frac{2}{3}[/tex] = a

y = [tex]\frac{2}{3}[/tex] (x - 3)² + 1 ← in vertex form

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

the equation of a parabola in factored form is

y = a(x - a)(x - b)

where a, b are the zeros and a is a multiplier

here zeros are - 1 and 3 , the factors are

(x - (- 1) ) and (x - 3), that is (x + 1) and (x - 3)

y = a(x + 1)(x - 3)

to find a substitute any other point that lies on the graph into the equation.

using (0, - 3 )

- 3 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )

1 = a

y = (x + 1)(x - 3) ← in factored form
