What is the graph of the linear function that is represented by the equation y= 1/2x-2
kondor19780726 [428]

Answer:

See picture attached.

Step-by-step explanation:

Start with the y-intercept of -2 and plot that on the graph. Then, use the slope of 1/2x to plot more points to help you draw the line. Remember rise over run. Go up one from the y-intercept and right two. If you need to, you can also go down one and left two.

Hope this makes sense.

The perimeter of the isoceles triangle is 54. The ratio of the leg to the base is 7:4. Find the length of the base
Norma-Jean [14]

9514 1404 393

Answer:

  12 units

Step-by-step explanation:

The ratio of the base to the other sides is ...

  4 : 7 : 7

The perimeter is a total of 4 +7 +7 = 18 ratio units, so each ratio units stands for 54/18 = 3 length units.

The base length is then ...

  (4 ratio units)(3 length units/ratio unit) = 12 length units

attashe74 [19]

Answer: \frac{11}{15}

Step-by-step explanation:

You know that:

- 2/5 of the spice mixture was oregano.

- 1/3 of the spice mixture was basil.

Then, to find the fraction of the total amount of spice mixture that was oregano and basil, you must add both fractions, as following:

- Find the least common multiply of the denominators:

LCM=5*3=15

- Divide the LCM by each original denominator and multiply the result by each numerator.

- Make the addition.

Then, the result is:

\frac{(2*3)+(1*5)}{15}=\frac{6+5}{15}=\frac{11}{15}

Which equation below represents the inverse function B(a) , which takes the trapezoid's area as input and returns as output the
8090 [49]
A(b)  = 12(b + 9) / 2
12(b + 9) = 2 A(b)
b + 9 = 2 A(b) / 12  = A(b) / 6
b = A(b)
      ----- - 9
        6

B(a)   =  a              
             --  -  9
