Answers

Answer 1

Answer:

30

Step-by-step explanation:

Answer 2

infinite solutions cause when you take out the 2 from the bottom equation, you get x + y = 4, which is the exact same equation as the first one, so literally any two values will result in the same for both

The x-coordinate of the vertex of the function y=-x²+bx+3 is 10. Determine the y-coordinate of the vertex.

Answers

Answer:

103

Step-by-step explanation:

Given function:

y = -x² + bx + 3

The x-coordinate of a quadratic function y = ax² + bx + c is determined by:

x = -b/2a

The given function has:

x = 10, and a = -1

Find the value of b:

10 = -b / -2b = 20

The function is:

y = -x² + 20x + 3

The y-coordinate of the vertex is:

y = -(10²) + 20*10 + 3 = -100 + 200 + 3 = 103

Answer:

Solution given:

y = -x² + bx + 3

we have

The x-coordinate of a quadratic function y = ax² + bx + c is determined by:

x = [tex] \frac{ - b}{2a} [/tex]

we have

x = 10, and a = -1

Substituting value of a in -b/2a

we get

b = 20

now

The y-coordinate of the vertex is:

y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

D. The company's chocolate bars weigh 3.2 ounces on average.

Step-by-step explanation:

We are given that  a company claims that its chocolate bars weigh 3.2 ounces on average.

The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.

Thus Option D is correct.

D. The company's chocolate bars weigh 3.2 ounces on average.

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?

Answers

Answer:

$64.89

Step-by-step explanation:

57.68 + 1.25 × 57.68

= 57.68 + 72.1

= 129.78

The original price was $129.78.

129.78 – 0.50 × 129.78

= 129.78 – 64.89

= 64.89

The discount price was $64.89.

y=x/3 - 4

Step-by-step explanation:

add x to get x to the other side

3y= x-12

divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form

Answer:

slope intercept form is y=mx+b

add x to both sides : 3y=x-12

divide by 3 on both sides : y=(1/3)x-4

the volume of a sphere is 4851 cubic cm find its diameter​

Answers

Answer:

The diameter is 21 cm

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter)  V = (4/3)π(d/2)³.  This simplifies to

       4πd³          πd³

V = ----------- = -----------

        3·8               6

Now equate V = (πd³/6) to 4851 cm³.  We must first solve this for d³ and then take the cube root of the result:

πd³ = 4851(6) = 29106.

Dividing this result by π yields 9264.7,

and taking the cube root of this is 21.  The diameter is 21 cm

the formula given for slope (m) calculated from two points is given as (y2-y1)/(x2-x1)

we are given the points (10,3) and (2,3)

label the values of the points to use for the formula:

x1=10

y1=3

x2=2

y2=3

plug into the formula

m=(3-3)/(2-10)

subtract

m=0/-8

divide

m=0

therefore, the slope is 0
