The graphs show the amount of sugar in two kinds of juice.
gizmo_the_mogwai [7]

Answer:

Pat a) The unit rate of graph at left is 25\ \frac{grams}{cup}

Part b) The unit rate of graph at right is 40\ \frac{grams}{cup}

see the attached figure

Step-by-step explanation:

we know that

The unit rate of a linear equation is the same that the slope of the linear equation

step 1

Find the slope of the graph at left

This graph represent a proportional relationship (because the line passes through the origin)

The slope is equal to the constant of proportionality k

k=\frac{y}{x}

we have the point (1,25)

substitute the values in the formula

k=\frac{25}{1}=25\ \frac{grams}{cup}

step 2

Find the slope of the graph at right

we have the points (2,80) and (3,120)

This graph represent a proportional relationship (because the line passes through the origin)

The slope is equal to the constant of proportionality k

k=\frac{y}{x}

Is necessary only one point to determine the constant of proportionality

take the point (2,80)

substitute the values

k=\frac{80}{2}=40\ \frac{grams}{cup}

<u>Verify</u>

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points (2,80) and (3,120)

substitute the values

m=\frac{120-80}{3-2}

m=\frac{140}{1}=40\ \frac{grams}{cup}

Help! I need help with this math problem
stiks02 [169]

Answer:

h(-1) is -1, h(-0.5) is 0 and h(1) is 1.

Step-by-step explanation:

functions :- an expression, rule or law that defines relationship between one variable and another variable. When a certain condition is fulfilled, then the result is corresponding to that condition.

  • h(-1)

In the function it is given that when x∈(-2,-1] then we get -1. Now here x=-1 satisfies the given condition. So, the answer will be -1.

  • h(-0.5)

In the function it is given that when x∈(-1,0] then we get 0. Now here x=-0.5 lies in the range (-1,0]. So, the answer is 0.

  • h(1)

In the function it is given that when x∈(0,1] then we get 1. Clearly, x=1 satisfies this range of values. So, we get 1.

Hence, the Answer is h(-1) = -1, h(-0.5) = 0 and h(1) = 1.
