We can easily silve it by splitting the middle term or by using the discriminate method *

x 2 +3x -70

x2 + 10x - 7x -70

x(x + 10) -7(x +10)

(x / 7) ( x + 10)

x = 7 or -10

Answer:

x=12

Step-by-step explanation:

1/2x - 5 = 10 - 3/4x ---> move like terms to the same side

1/2x + 3/4x = 10 + 5 ---> calculate

5/4x = 15 ---> multiply both sides by 4/5

x = 12

I factored using the berry method

Answer:

[tex] \frac{10}{53 \times 46 \times 26} [/tex]

Step-by-step explanation:

The probability of matching the number drawn on the gold ball is

[tex] \frac{1}{46} [/tex]

The number of possible pairs of numbers from 1 to 53 is

[tex] \binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26[/tex]

Choosing 5 numbers, you are choosing 10 different pairs:

[tex] \binom{5}{2} = \frac{5 \times 4}{2} = 10[/tex]

Therefore the probability of correctly matching the drawn pair is

[tex] \frac{10}{53 \times 26} [/tex]

Thus, the probability of winning (matching the pair AND the gold ball) is

[tex] \frac{10}{53 \times 46 \times 26} [/tex]

257169554605/657 or about 391430068

Answer:

1844540.13242 or 1844540 R 87

Step-by-step explanation:

(393874112 ) - (1605736979) = -1211862867 ÷ 657 = 1844540.13242

The long division work is in the image.

Answer: A, D

Step-by-step explanation:

For number 7 the answer is A

For number 8 since you are only moving it is the same size, therefore, producing a congruent image for all 3 of those translation. So for 8 the answer is d.

Answer:

Look Below

Step-by-step explanation:

1) The answer is A. It is A because if you want a reflected images across the Y-Axis, you want just the X value to change. Not the Y. So since the Y is positive and the X is positive, if you want a reflected image you want the X to be negative and the Y to be positive.

2) The answer is D. It is D because those are all forms that will produce a Congruent Image.

2)

Okay so because the right side is two times the length and width of the left side, we need to divide 20 and 14 by 2 which gives us 10 and 7. That means x+2 = 10 so we need to subtract 2 from each side which gives you 8. Therefore, x = 8.

20/2 = 10

10 - 2 = 8

x = 8

Answer:

the slope should represent the fee of each class

.

the vertical intercept is the membership fee

Answer:

the y-inyetcept means the starting fee to join

and the slope means fee per class paid by the customers.

Step-by-step explanation:

undefined

because zero slope is side ways  

Answer:

0.5

Step-by-step explanation:

rate of change is just a synonym for slope and the equation for slope is y=mx +b where m is the slope so 0.5=m and if m= slope then 0.5=slope=rate of change :)

Answer:

185

Step-by-step explanation:

Population size = 800

Sample size = 160

Number of blue-eyed rabbit in sample = 37

The proportion of blue-eyed rabbit in the sample is :

p = number of blue eyed rabbit / sample size

p = 37 / 160 = 0.23125

Estimated number of blue eyed rabbit in population :

p * population size

0.23125 * 800

= 185

Answer:

if those measurements are degrees, then yes. If those measurements are the side lengths, then no.

Step-by-step explanation:

all angles on a triangle must had up to 180 degrees.

the two smaller sides of the triangle must add up to be larger than the largest side.

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022

For this case we have that by definition, the volume of a sphere is given by:

Where:

r: It is the radius of the sphere

According to the data we have to:

Substituting we have:

The option that best fits is option B.

Answer:  v=113cm3

The option that best fits is option B.

...............................................................................................................................................

Answer:

V ≈ 904 cm³

Step-by-step explanation:

Let r denotes radius

r = 6cm (given)

As it a sphere of radius 6cm,

Volume of a sphere,

V = 4/3 π r³

V = 4/3 (3.14) (6)³

V = 4/3 (3.14) x 216

V = 4 (3.14) x 72

V = 12.56 x 72

V = 904.32 cm³

Rounding off,

V ≈ 904 cm³

Answer:

2(x – ½)(x + ½)

Step-by-step explanation:

2x² – ½

The above expression can be factorised as follow:

2x² – ½

2 is common to both 2 and ½. Thus,

2x² – ½ = 2[x² – ¼]

Recall

(½)² = ¼

Thus,

2[x² – ¼] = 2[x² – (½)²]

Difference of two squares

2(x – ½)(x + ½)

Therefore,

2x² – ½ = 2(x – ½)(x + ½)
