Answer:

x = -1/2, 7

Step-by-step explanation:

2x^2 = 13x + 7

bring everything to one side: 2x^2 - 13x - 7 = 0

factor it out: 2x1 = 2 and -7x1 = -7.

-7x2 = -14 and 1x1 = 1

-14 + 1 = -13, so these numbers work

you end up with (2x + 1)(x - 7) = 0

solve each section:

2x + 1 = 0                         x - 7 = 0

2x = -1                              x = 7

x = -1/2

Answer:

m<CAO = 56

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,

(m<DOA) + (m<CAO) = 180

Substitute,

3x + 40 + 2x = 180

Simplify,

5x + 40 = 180

Inverse operations,

5x + 40 = 180

     -40    -40

5x = 140

/5     /5

x = 28

Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.

<CAO = (2x)

= 2(28)

= 56

Answer:

33.83

Answer:

x = 64

Step-by-step explanation:

The 3 angles on the right lie on a straight line and sum to 180° , that is

90 + x + 26 = 180

x + 116 = 180 ( subtract 116 from both sides )

x = 64

Answer:

64

Step-by-step explanation:

You have to do 90 - 26, which will then give you the answer 64

Double check it: 26 + 64 = 90.

Answer:

85,696

Step-by-step explanation:

4 x 104 = 416

2 x 103 = 203

No sign between parentheses means that you have to multiply the two outcomes of the parentheses.

416 x 203 = 85,696

Answer:

x = 4, y = -10

Step-by-step explanation:

if both expressions equal 'y' then you can solve by setting them equal to each other:

-5x + 10 = -2x - 2

-3x + 10 = -2

-3x = -12

x = 4

find 'y':

y = -5(4)+10

y = -20 + 10

y = -10

Answer:

2, 0, -2, -4

Step-by-step explanation:

an = 4 − 2n

a1 = 4 - 2(1) = 2

a2 = 4 - 2(2) = 0

a3 = 4 - 2(3) = -2

a4 = 4 - 2(4) = -4

Answer:

(2, 0, -2, -4)

Step-by-step explanation:

a(1) = 4 - 2(1)

= 4 - 2

= 2

a(2) = 4 - 2(2)

= 4 - 4

= 0

a(3) = 4 - 2(3)

= 4 - 6

= -2

a(4) = 4 - 4(4)

= 4 - 8

= -4

Answer:

789 to nearest whole number.

Step-by-step explanation:

In 4 years its increased from 220 to 350.

350 = 220(e)^4k  where k is some constant.

e^4k = 350/220

4k = ln (350/220) = 0.4643

k = 0.1161

The equation  of growth is therefore

P = 220e^0.1161t)

So  in 2011 ( t = 11 years) the

Population = 220 * e^(11*0.1161)

= 789.

Answer:

y=3x+3

Step-by-step explanation:

Let's solve for y.

2y−6=6x

Step 1: Add 6 to both sides.

2y−6+6=6x+6

2y=6x+6

Step 2: Divide both sides by 2.

2y /2 = 6x+6 /2

y=3x+3

Answer:

y=3x+3

Step-by-step explanation:

add 6 to both sides and then divide both sides by 2
