Graph parallelogram ABCD on the graph
Anvisha [2.4K]

Answer: 25 square units

Step-by-step explanation:

We mark the points, A(2,0), B(7,0), C(10,3), D (5,3). on a graph and then joined them to make parallelogram ABCD as provided in the attachment.

Area of parallelogram  = Base x corresponding height

From the figure, base AB = 7 - 2 units = 5 units

corresponding height: h= 5 units

Now , Area of parallelogram  ABCD = base AB x corresponding height

= 5 x 5 square units

= 25 square units

Hence,  the area of parallelogram  ABCD is 25 square units .

marshall27 [118]

Answer:

(a)6 feet

(b)24 sections

Step-by-step explanation:

(a)We are required to find the length of the Giant Sub.

If each section is 1/3 of a foot long and there are 18 equal parts.

Length of the Giant Sub =

Length per Section X Number of Sections

= 1/3 X 18 = 6 feet

(b)If each section is 1/4 of a feet long

Length of the Giant Sub =

Length per Section X Number of Sections

6= 1/4 X Number of Sections

Number of Sections =6 X 4 =24 sections

the slope of line PQ is m= 1/4. find the equation of the line that is parallel to line PQ and that has the y intercept b= -3
nevsk [136]
For this case we have that the generic equation of the line is given by:
 y = mx + b

 Where,
 m: slope of the line
 b: intersection with the y axis.
 Since the line is parallel to PQ, then the slopes are equal.
 We have then:
 m = 1/4.

 On the other hand we have:
 b = -3

 Substituting values we have:
 y = (1/4) x - 3
 Answer:
 The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
 y = (1/4) x - 3
