143 is added to twice a number and this sum is multiplied by 2, the result is the same as if the number is multiplied by 0 and 2 is added to the product. What is the
number?

Answers

Answer:

-71

Step-by-step explanation:

let 'n' = a number

2(143 + 2n) = 0n + 2

2(143 + 2n) = 2

143 + 2n = 1

2n = -142

n = -71

Find the fourth degree polynomial function with zeros 6,-6,6i

Answers

Answer:

See below

Step-by-step explanation:

6 is a solution to x-6=0, -6 is a solution to x+6=0, and 6i is a solution to x^2+36=0. So, we can do (x-6)(x+6)(x^2+36) to get (x^2-36)(x^2+36) which gets us x^4-1296. Therefore, the fourth degree polynomial with zeroes 6, -6, 6i is x^4-1296

What is the slope and y-Intercept of the equation 3(y – 2) + 6(x + 1) - 2 = 0?
A. Slope = -2, y-intercept = 2/3
B Slope = 2, y-intercept =2/3
C Slope = -2, y intercept = -2/3
D Slope = 2, y intercept= -2/3
E Slope = -2, y intercept = 3/2

Answers

Answer:

A. Slope = -2, y-intercept = 2/3

Step-by-step explanation:

Convert the given equation into slope-intercept form:

3(y - 2) + 6(x + 1) - 2 = 03y - 6 + 6x + 6 - 2 = 03y + 6x - 2 = 03y = - 6x + 2y = - 2x + 2/3

The slope is -2, the y-intercept is 2/3

Correct choice is A

⇒ 3(y - 2) + 6(x + 1) - 2 = 0

⇒ 3y - 6 + 6x + 6 - 2 = 0

⇒ 3y = -6x + 2

⇒ y = (-6x + 2)/3

⇒ y = -2x + ⅔

FINAL ANSWER :

Slope = -2

Y - intercept = +⅔

Answer :

Option (a) is the correct answer .

ANSWER: $2.00 in all the rounded cost,
$10 for apple, $8 for oranges, $6 for bananas, and $24 total

EXPLANATION:

First let’s round round to the nearest dollar.

Apples cost 1.75 for a pound, that rounded is 2.00

So $2.00 is the estimated amount.

Oranges cost 2.35 per pound. That rounded is 2.00

So the estimated amount is $2.00

Bananas cost 1.50 per pound. That rounded is also 2.00.

So the estimated amount is $2.00

Now we know that rounded amount we just multiply.

If apples cost about 2.00 per pound and she bought 5 pounds just multiply by 5.

2.00 x 5 = $10.00

She paid about $10.00 for apples

If she bought 4 pounds of oranges and one pound of oranges cost about 2.00, multiply 2 by 4.

2.00 x 4 = 8.00

She paid about $8.00 for oranges.

If bananas cost 2.00 per pound and she bout 3 pounds, multiply by 3.

2.00 x 3 = $6.00

She paid $6.00 for bananas.

Now to find the total amount she spent add them all together.


$10.00
$ 8.00
$ 6.00

$24.00

if p(q) = q^2 + 4q − 12,then what is p(−1)?

Answers

Answer: p(-1) = -15

Step-by-step:

Plug -1 into the equation in place of q.

p(-1) = (-1)^2 + 4(-1) - 12

p(-1) = (-1)^2 - 4 - 12

p(-1) = (-1)^2 -16

p(-1) = 1 - 16

p(-1) = -15
1): "q2" was replaced by "q^2".

Step by step solution :

STEP
1
:
Trying to factor by splitting the middle term

1.1 Factoring q2-4q-12

The first term is, q2 its coefficient is 1 .
The middle term is, -4q its coefficient is -4 .
The last term, "the constant", is -12

Step-1 : Multiply the coefficient of the first term by the constant 1 • -12 = -12

Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -4 .

-12 + 1 = -11
-6 + 2 = -4 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 2
q2 - 6q + 2q - 12

Step-4 : Add up the first 2 terms, pulling out like factors :
q • (q-6)
Add up the last 2 terms, pulling out common factors :
2 • (q-6)
Step-5 : Add up the four terms of step 4 :
(q+2) • (q-6)
Which is the desired factorization

Equation at the end of step
1
:

(q + 2) • (q - 6) = 0
STEP
2
:
Theory - Roots of a product

2.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

2.2 Solve : q+2 = 0

Subtract 2 from both sides of the equation :
q = -2

Solving a Single Variable Equation:

2.3 Solve : q-6 = 0

Add 6 to both sides of the equation :
q = 6

Help!!! I'm desperate to find the answer, will give brainliest to first person that answers the question in the photo!

Answers

Answer:

  k = -4

Step-by-step explanation:

The remainder theorem tells you that the remainder from division f(x)/(x -k) is f(k). You want the value of k such that ...

  f(k) = -15

Looking on the given graph, you find that k must be -4. That is, ...

  f(-4) = -15

  k = -4

The divisor with k=-4 is (x -(-4)) = (x +4). The second attachment shows the division of f(x) by (x+4). The remainder is shown on the bottom line.

Janie flips a coin 70 times and records if it comes up heads. If getting heads is a success, what is the probability of a failure? 0. 2 0. 5 0. 7 1. 0.

Answers

The probability of a failure is 0.5

Probability is the likelihood or chance that an event will occur.

Probability  = Expected outcome/Total outcome

Since Janie flips a coin 70 times, then the total outcome is 70

The probability of getting a failure will be 50% of the total times;

Expected outcome  = 50% of 70

Expected outcome = 35

Pr(a failure) = 35/70

Pr(a failure) = 0.5

Hence the probability of a failure is 0.5

What value of n makes the equation TRUE?

Answers

Find and solve the equation for the value of n (by finding the value of n, you are finding which value of n that makes the statement true.)

3.74 = 0.4n + 2.5

3.74 - 2.5 = 0.4n

1.24 = 0.4n

n = 3.1

So the value of n which makes the statement true is 3.1

The value of n for the equation to be true is n = 3,1

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A , 3.74 = 0.4n + 2.5

Now ,

3.74 = 0.4n + 2.5

Subtracting 2.5 on both sides of the equation , we get

0.4n = 3.74 - 2.5

0.4n = 1.24

Divide by 0.4 on both sides of the equation , we get

n = 3.1

Therefore , n = 3.1

Hence , the value of n for the equation to be true is n = 3.1

Harry orders the bouquet with a certain number of roses, the cost will be the same with either
flower shop. How many roses would there be? What would the total cost be?

Answers

The number of roses purchased will be; 12 roses

The total cost of the bouquet is; $51

Let number of roses be x

For Summerfield florists;

At $1 per rose and $39 for the vase, cost is;

C = x + 39

For grayson's flowers;

At $3 per rose and $15 for the vase,total cost is;

C = 3x + 15

We are told when he orders a certain number of roses, the cost will be the same with each flower shop.

Thus;

x + 39 = 3x + 15

3x - x = 39 - 15
