Answer:

The line is y = (1/2)x + 3

Step-by-step explanation:

We can calculate a slope.  I'll use the two points (-4,1) and (-1,2.5).

Rise = (2.5-1) = 1.5

Run = (-1-(-4)) = 3

Rise/Run = Slope = (1.5/3.0) = 1/2

Find b, the y-intercept, by using point (-4,1) in the equation y = (1/2)x + b

y = (1/2)x + b

1 = (1/2)*(-4) + b

1 = -2 + b

b=3

The line is y = (1/2)x + 3

Albert receives $0.30 per pound for 1 to 49 pounds of glass bottles he recycles. He receives $0.40
Marina86 [1]

Answer:

Yes

Step-by-step explanation:

The amount of money Albert receives is described by the expression

y = \begin{cases}0.30x  & \quad \text{if } 0 \leq x \leq 49 \\0.40x & \quad \text{if } x > 50\\\end{cases}

The graph is shown below.

To determine if the relation is a function,  we can use the vertical line test:  

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

Use your graphing calculator to determine if the equation appears to be an identity or not by graphing the left expression and r
andrezito [222]

Answer:

(sec x)+(cos x)=(tan x)*(sin x)\\identities\\(sec x)= 1/cos x\\(tan x)=sin x/cos x\\\\and\\(cos x)^{2}+(sin x)^{2}=1\\(cos x)^{2}=1-(sin x)^{2}\\\\(1/cos x )+(cos x) = (sin x)*(sin x)/(cos x)\\ [(1/cos x)+(cos x)]*(cos x)=(sin x)^{2}\\\\1+(cos x)^{2}=(sin x)^{2}\\1+1-(sin x)^{2}=(sin x)^{2}\\2=2*(sin x)^{2}\\2/2=(sin x)^{2}\\1=(sin x)^{2}\\\\This is not true ,so\\(sec x)+(cos x)\neq (tan x)*(sin x)
