The graph of a linear equation contains the points (3,11) and (-2,11). Which point also lies on the graph?(YOU MUST SHOW WORK)

dexar [7]

Y= ax+b

when x=3, y=11 and when x= -2, y=11
3a+b=11
-2a+b=11 | * -1
3a+b=11
2a-b=-11
------------
5a=0, a=0:5, a=0
⇒ b=11
y=11 for every x
So ( 1,11) or (2,11) are also points on the graph

The square below represents one whole. Express the shaded area as a fraction, a decimal, and a percent of the whole. Fraction: D

Igoryamba

Answer:

Fraction = $\frac{19}{50}$

Decimal = 0.38

Percent = 38%

Step-by-step explanation:

Number of shaded rectangles = 38

Total number of rectangles = 100

Fraction represented by the shaded area = $\frac{\text{Number of blocks shaded}}{\text{Total number of blocks}}$

= $\frac{38}{100}$

= $\frac{19\times 2}{50\times 2}$

= $\frac{19}{50}$

Decimal form of the shaded area = $\frac{38}{100}$ = 0.38

Percent of the shaded area = $\frac{38}{100}$ = 38%
