Looking at the number line, it is visible that the circular marks at the ends of the shaded region are shaded as well, not empty. This indicates that the values that these marks lie on, 55 and 65, must be included in the range. The only option that fits this is A, a temperature range within 5 degrees of 60 degrees Farenheit<span>. This is because 5 degrees less than 60 degrees is 55, while 5 degrees greater than 60 is 65 degrees.</span>

Which of the sets of equations represent the two lines graphed?

Oksi-84 [34.3K]

Answer:

B) y = x + 2 and y = -x - 4

Step-by-step explanation:

Let the equation of a straight line with x-intercept 'a' and y-intercept 'b' be

$\frac{x}{a} + \frac{y}{b} = 1$

The line with positive slope has x-intercept a=-2 and y-intercept b=2.

Its equation is:

$\frac{x}{ - 2} + \frac{y}{2} = 1$

Multiply through by 2

$- x + y = 2$

Solve for y,

$\boxed {y = x + 2}$

For the line with a negative slope,

the x-intercept is a=-4 and the y-intercept is b=-4

Its equation is

$\frac{x}{ - 4} + \frac{y}{ - 4} = 1$

Multiply through by -4

$x + y = - 4$

Solve for y

$\boxed {y = - x - 4}$

For the diagram at right, write and solve an equation to find x

Tomtit [17]

Answer:

x = 24

Step-by-step explanation:

The formula for determining the sum of interior angles is:

$(n-2) * 180$

$4 * 180 = 720$

Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.

$(2x+3) +(3x+12) + (7x+14) + (9x+2) + (4x+8) + (3x+9) = 720\\28x + 48 = 720\\28x = 672\\x = 24$

The equation and answer above shows how to find x, which equals 24.
