Answer:

y = -1/4x - 1

Step-by-step explanation:

The equation of a line is y = slope*x + y-intercept

Find the slope by picking two points shown on the graph and doing (y1-y2)/(x1-x2): (4, -2) & (-8, 1) = (-2-1)/(4-(-8) = -3/12 = -1/4 so the slope is 4.

Find the y-intercept by seeing where the line crosses the y-axis: y= -1

So therefore, y = -1/4x - 1

5. Choose the best answer.
lyudmila [28]

The slope-intercept form: y = mx + b

So we need to "solve" given equation for y

3.3x - 3y = 2.4           {subtracting 3.3x from both sides}

- 3y = 2.4 - 3.3x        {dividing both sides by (-3)}

  y = -0.8 + 1.1x

Therefore:

<h3>Slope:                         m = 1.1</h3><h3>y -intercept :               b = - 0.8</h3><h3>slope-intercept form:   y = 1.1x - 0.8</h3>

What is the approximate area of the shaded sector in the circle shown below
harina [27]

Answer:

Option A. 283 cm²

Step-by-step explanation:

to find the area of the shaded sector, we use the formula:

 \frac{\text{angle given}}{360^\circ}\times \text{area of the circle}

where area of the circle = πr²

∴ for the given circle,

\text{Area of the sector}=\frac{\text{given angle}}{360^\circ} \times \pi r^2

                            =  \frac{100}{360}\times 3.14\times 18\times 18

                            = \frac{100}{360}\times 1017.36

                            = 282.6

                            ≈ 283 cm²

The approximate area of the shaded sector is 283 cm².

Pls help:(((( I don’t understand
marissa [1.9K]

Answer:

x = 32°

Step-by-step explanation:

The main concept is that all the angles in a triangle add up to 180.

(For example, 60° on all three angles make it an equilateral triangle)

Since all the angles add to 180°,

x + 98 + 5 0 = 180

x + 148 = 180

Subtract 148 from both sides:

x = 32

Therefore, the value of x is 32°.
