Which ordered pairs are solutions to the inequality 2x-y>1?

Mathematics
1 answer:
RideAnS [48]3 years ago
8 0

Answer:

Any points in the shaded region including (2,-2) and (-3,-8)

Step-by-step explanation:

Convert the line into slope intercept form and graph it.

2x-y > 1 becomes -y>1-2x. Divide both sides by -1 and you get y<2x-1. Graph it with the shaded area on the right and a dashed line.

Any point which falls within the shaded red of the graph is a solution. No points on the line since it is not equal to (its dashed) are solutions. Check the location of your points to verify that they fall within this area.

(-3, -8)  ---Yes

(-1, -3)  ---No

(0, 5)  --- No

(1, 6)  --- No

(2, -2) ---Yes

BlackZzzverrR [31]

Answer:

4 2/3  cm

Step-by-step explanation:

When we have area, it is the related to the scale factor by the scale factor squared

Area large/ area of small = 49/9

Take the square root

sqrt(49/9)  = 7/3

The scale factor is 7/3    large to small

The small side is 2 cm

large         7            x cm

--------   =  ------ =  -----------

small           3           2 cm

Using cross products

7*2 = 3x

Divide by 3

14/3 = 3x/3

14/3 = the large side

4 2/3  cm

HELPP describe the mistake made in the work shown
solmaris [256]

Step-by-step explanation:

-2(8m+8) = -16

-16m-16 = -16

-16m = -16+16

-16m= 0

m= 16

Therefore, the value of m is 16.

Sorry but is that below another question? or is it whole a same question?

-16m÷16 = -32÷16

-m = -2

remove those "-" signs from both sides. So, the answer is 2.
