The graph of linear function g is shown on the grid. What is the zero of g? (-8,3) (-3,-4.5)
Ratling [72]

Answer:

Zero of the function = (-6, 0)

Step-by-step explanation:

Let the equation of the function given in the graph is,

y = mx + b

where m = slope of the line passing through two points (x_1,y_1) and (x_2,y_2) = \frac{y_2-y_1}{x_2-x_1}

b = y-intercept of the line

From the graph attached,

Slope of the line passing through (-8, 3) and (-3, 4.5) = \frac{-4.5-3}{-3+8} = -1.5

y - intercept 'b' = -9

Therefore, equation of the line will be,

y = -1.5x - 9

Function representing this line will be,

g(x) = -1.5x - 9

Zeros of the given function will be,

g(x) = 0 Or x-intercept

-1.5x - 9 = 0

x = -6

Therefore, zero of the given function is (-6, 0).

How to solve slope intercept form with 4y=x+3
mrs_skeptik [129]
<h3>Answer: y = (1/4)x + 3/4</h3>

m = 1/4 = slope

b = 3/4 = y intercept

===================================================

Explanation:

The goal is to solve for y.

Divide both sides by 4 and simplify like so

4y = x+3

4y/4 = (x+3)/4

y = (x+3)/4

y = x/4 + 3/4

y = (1/4)x + 3/4

This equation is in slope intercept form y = mx+b

m = 1/4 is the slope

b = 3/4 is the y intercept

The graph is a straight line that goes through (1,1) and (5,2)

The cost of coffee is determined by the type of coffee beans that are mixed together. The cost of a local mix of arabica and rob
KatRina [158]

      700a + 1200r = 1,000,000

700(1000) + 1200r = 1,000,000

700,000  + 1200r = 1,000,000

                    1200r = 300,000

                           r = \frac{300,000}{1200} = \frac{3000}{12} = 250

Answer: 250 pounds of robusta beans
