x + 8 = 4
help me to doive this​

The variable x represent the number of months in which he runs.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change (slope) and b is the y intercept.

Given that Sean one-half mile on his first run and adds two miles a month to his run. It is given by the equation f(x)= 0.5 + 2x

The variable x represent the number of months in which he runs.

Answer:

The vertex will be at ( -1,-2)

Step-by-step explanation:

g(x) = |x + 1| - 2.

The vertex of g(x) = |x |  is ( 0,0)

y = f(x) + C C < 0 moves it down  

y = f(x + C) C > 0 moves it left

We shift this  to the left 1 unit and down 2 units

( 0 -1, 0-2)

The vertex will be at ( -1,-2)

Given: g(x) = |x + 1| - 2.

We start at g(x) = |x| at (0, 0)

c < 0 moves it down

y = f(x) + c

2 units down

c > 0 moves it left

y = f(x + c)

1 unit to the left

After the shift, we see the vertex being at (-1, -2).

Best of Luck!

Answer:

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

Step-by-step explanation:

This is for the first question.

Slope-intercept is:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We are given the slope of [tex]-\frac{3}{2}[/tex] and a y-intercept of 2.

Plug in the values:

[tex]y=mx+b\rightarrow\boxed{y=-\frac{3}{2}x+2}[/tex]

Answer:

43,51, 86

Step-by-step explanation:

The sum of the angles of a triangle are 180

x+ x+8+2x = 180

Combine like terms

4x+8 = 180

Subtract 8  from each side

4x+8-8= 180-8

4x= 172

Divide each side by 4

4x/4 = 172/4

x=43

x+8 = 43+8 = 51

2x = 43*2 = 86

I got you, bro!

Answer:

x = 43

The angle measures of the triangle, in order from least to greatest, are 43, 51, and 86.

Step-by-step explanation:

4x + 8 = 180

Subtract 8 from both sides.

4x = 172

Divide.

x = 43

Answer:

The upper bound of the area is 6.69375 cm²

The lower bound of the area is 6.32875 cm²

Step-by-step explanation:

The question relates to measurements and accuracy

The given information are;

The base length of the triangle = 3.1 cm

The height of the triangle = 4.2 cm correct to one decimal place

The lower bound for the base length of the triangle = 3.05 cm

The upper bound for the base length of the triangle = 3.15 cm

Similarly, the lower bound for the height of the triangle = 4.15 cm

The upper bound for the height of the triangle = 4.25 cm

The formula for calculating the area of a triangle is given by the following formula;

Area of a triangle = 1/2 × Base × Height

The upper bound of the area = 1/2 × The upper bound of the base × The upper bound of the height

The upper bound of the area = 1/2 × 3.15 × 4.25 = 6.69375 cm²

The upper bound of the area = 6.69375 cm²

The lower bound of the area = 1/2 × The lower bound of the base × The lower bound of the height

∴ The lower bound of the area = 1/2 × 3.05 × 4.15 = 6.32875 cm²

The lower bound of the area = 6.32875 cm²

Answer:

S = 14.14

Step-by-step explanation:

The area of a square is S*S or S^2.

So, if we know that the area of the square patio is 200, we can say that

S^2 = 200.

S = sqrt(200)

S = 14.14 ft.
