Answer:

[tex] \large \boxed{y = - 0.5x + 5}[/tex]

Step-by-step explanation:

Goal

Given

Step 1

[tex] \large{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]

Substitute the coordinate points in

[tex]m = \frac{3 - 2}{4 - 6} \\ m = \frac{1}{ - 2} \\ m = - \frac{1}{2} \longrightarrow - 0.5 \\ m = - 0.5[/tex]

Step 2

[tex] \large{y = mx + b}[/tex]

Substitute m = -0.5

[tex]y = - 0.5x + b[/tex]

Step 3

Substituting both coordinate points still give the same answer.

Step 3.1

[tex]y = - 0.5x + b \\ 3 = - 0.5(4) + b \\ 3 = - 2.0 + b \\ 3 = - 2 + b \\ 3 + 2 = b \\ 5 = b[/tex]

Step 3.2

[tex]y = - 0.5 x+ b \\ 2 = - 0.5(6) + b \\ 2 = - 3.0 + b \\ 2 = - 3 + b \\ 2 + 3 = b \\ 5 = b[/tex]

Step 4

[tex]y = - 0.5x + b[/tex]

Substitute b = 5 in the equation.

[tex]y = - 0.5x + 5[/tex]

Hence, the equation is y = -0.5x + 5

Answer:

4√2/7

Step-by-step explanation:

Suppose cos(x)=-1/3, where pi/2≤x≤ pi

tan(2x) = sin(2x)/cos(2x)

Since sin2x = 2sinx cosx

cos 2x = 2cos²x-1

Substitute

tan(2x) = 2sinx cosx/ 2cos²x-1

Given cosx = -1/3

adjacent = -1

hyp = 3

opp = √3²-(-1)²

opp = √9-1

opp = √8

sinx = opp/hyp

sinx = √8/3

tan(2x) = 2sinx cosx/ 2cos²x-1

tan(2x) = 2(√8/3)(-1/3)/ 2(-1/3)²-1

tan2x= (-2√8/9 )÷ (2/9 - 1)

tan2x = -4√2/9 * 9/-7

tan 2x = 4√2/7

Answer:

70 degrees

Step-by-step explanation:

The exterior angle in a triangle is equal to the sum of the two opposite interior angles

So,

the two interior angles in the question are U and T while the exterior angle is V.

Using this,

U+T =V

U+50 = 120

(make U the subject of formula)

U = 120 - 50

U = 70 degrees

Step-by-step explanation:

if a rectangle has 4 sides and there are two lengths and two widths

then we could split 80 by 2 and minus 4 from the length and then split that into two.

then your answer would be  and 36 and 44

and the total answer would be half of each so the L=22 and L=22

and the W=18 and W= 18

sorry if this is wrong it least i tried :9

Answer:

C

Step-by-step explanation:

Step 1: Find your legth and width

Length = x + 5

Width = 3

Step 2: Use area formula to find area

l x w = A

(x + 5) x 3 = A

A = 3(x+5)

Step 3: Therefore Statement

Thereforethe answer to the question is C. 3(x+5)

Answer:

C. 3(x + 5)

Step-by-step explanation:

area of rectangle = length * width = width * length

A = area of largest rectangle

a1 = area of left rectangle

a2 = area of right triangle

The largest rectangle is made up of the the two smaller rectangles.

A = a1 + a2

Left rectangle: a1 = WL = 3x

Right rectangle: a2 = WL = 3 * 5

Total area of the two small rectangles:

A = a1 + a2 = 3x + 3 * 5

Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:

A = 3x + 3 * 5 = 3(x + 5)

The area of the largest rectangle is 3(x + 5)

We can also find an expression for the area of the largest rectangle directly by looking at its length and width.

The length of the largest rectangle is x + 5.

The width of the largest rectangle is 3.

A = WL

Substitute 3 for W, the width.

Substitute x + 5 for L, the length.

A = 3(x + 5)

Answer: C. 3(x + 5)

Answer:

1. x(x+8)

2. x(x−4)

3. (x−1)(x+2)

4.(x+3)(x−3)

5. (x+11)(x+11)

6. (x−4)(x−4)

Step-by-step explanation:

Answer:

width= 4

hieght- 5.65

Step-by-step explanation:

so first lets find the diestnce between 0,0 and 4,4

which is 4 root 2

which is approciamitlty 5.65 and this would be the hieght

the width would be 22.64/5.65= approxiamitly 4

Answer:30

Step-by-step explanation:

30 times he can expect to spin a number less than 5.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

A spinner with six section numbered from 1 to 6.

total number of times spins = 150

So, the number of times the number comes less than 5 is

= 150 x 1/5

= 150/5

= 30

Answer:

The Answer is YES

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Use Pythagorean theorem.

The longest side will be the hypotenuse

Hypotenuse² = 17² = 289

base² + altitude² = 15² + 8²

                           = 225 + 64

                          = 289 =Hypotenuse²

b)

Obviously from the first part that the unlimited plan is cheaper when sending 200 messages, but the costs numerically would be.

Unlimited plan costs $30 while the other plan costs
