Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

<u>       -7    -7</u>

2x = 8

divide by 2 to isolate x

<u>x = 4</u>

2nd pic) y - 3 <= 6

y - 3 <= 6

<u>   +3      +3</u>

<u>y <= 9</u>

<u />

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

<u>    -0.5         -0.5</u>

x = x + 5.5

NO SOLUTION

4th pic)  5m + 10 <= 130

5m + 10 <= 130

<u>       -10        -10</u>

5m <= 120

divide by 5 to isolate the m

<u>m <= 24</u>

5th pic) 2c - 8 > 0

2c - 8 > 0

<u>      +8   +8</u>

2c > 8

divide by 2 to isolate the c

<u>c > 4</u>

Select the correct answer. Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% ch
GREYUIT [131]

Answer:

Option A 0.1698

Step-by-step explanation:

Given that Jason has a chance for getting oil as 45%

THe kit he buys show accurate result with 80% probability

Let A1- Event that the land has oil

A2 - Event that the land has no oil

B- The test gives negative result

A1 and A2 are mutually exclusive and exhaustive

P(A1) = 0.45 and P(A2) =0.55

Hence we can use Baye theorem

Then P(B) = P(A1B)+P(A2B)=0.45(0.20)+0.55(0,80)\\=0.09+0.0.44\\=0.53

Reqd prob =P(A1/B) =

\frac{P(A1B)}{P(B)}\\ =\frac{0.09}{0.53}\\\\=0.1698

If a building was placed at coordinates (-5,5), what would be the new coordinates if rotated 270° counterclockwise around the or
Brums [2.3K]

The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).

So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).

Hope this Helps!!

2x + y =8 and 4x -2y = 6
irakobra [83]

Answer:

x=1.25 and y=-5.5

Step-by-step explanation:

2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

blsea [12.9K]

Answer:5r2+2

Step-by-step explanation:

Distribute the Negative Sign:

=4r2−3r+2+−1(−r2−3r)

=4r2+−3r+2+−1(−r2)+−1(−3r)

=4r2+−3r+2+r2+3r

Combine Like Terms:

=4r2+−3r+2+r2+3r

=(4r2+r2)+(−3r+3r)+(2)

=5r2+2
