7 less than -2 times a number x is greater than or equal to 41.

1 answer:

7 0

-2x-7≥41 is the equation (you have to first multiply then subtract and that's why you can't combine) 41+7=48 divided by -2 equals -24. Any number less than -24 works so your number range would be from -infinity to -24.

Step-by-step explanation:

$1km =1000m \\ x = 0.035m$

$use \: \: cross \: \: multipication$

$0.035 \times 1 = 1000x \\ 0.035 = 1000x \\ \frac{0.035}{1000} = \frac{1000x}{1000} \\ x = 0.000035km$

Which ordered pair is a solution of the equation y= -5x +4......(2,14) (5, -29) (3, -19) (5, -21)

Ratling [72]

1) 2x+4y=10
3x+5y=14 .

find d2, dx2, and dy

2) Solve the system of equations algebraically and show your work.

2x + 3y = 12
2x - y = 4

3) Which of the ordered pairs (5,5),(5,0) and (-3,2) can be found in the shaded solution area for the system of inequalities below? (The ordered pair must be in the double shaded region or it is not a solution of the system.)

x+2y<6
2x+y > or equal too 9 so yea hoped this helped

What is the answer Factorise: 2x² +7x+6.<br><br>

Mila [183]

Answer:

2x + 3 )(x + 2 )

Step-by-step explanation:

2x² + 7x + 6

Find two numbers multiplied together to get 6

and if you multiply one by 2, the answer is 7:

Tested:

6 & 1 but 6 · 2 + 1 = 13 or 6 + 2 · 1 = 8 No

2 & 3 and 2 · 2 + 3 = 7 Yes

2x² = 2x & x

all signs are positive

trinomial factoring ( )( )

( + )( + )

2 and 3 are the numbers to use (2x + 3 )(x + 2 ) or (2x + 2) (x + 3)

The largest number goes with the 2x.

Therefore (2x + 3 )(x + 2 )

Check 2x(x + 2) + 3(x + 2)

2x² + 4x + 3x + 6

2x² + 7x + 6 checked

I am just confused can someone help please...

prohojiy [21]

The answer is B

sin=Opposite/Hypotenuse

sin=28/100

Divide numerator and denominator by 4

sin=7/25

Cosine=adjacent/hypotenuse

cos=96/100

Divide numerator and denominator by 4

cos=24/25

Tangent=opposite/adjacent

tan=28/96

Divide numerator and denominator by 4

tan=7/24
