3-2(k-2)-7(2k-3)

Answers

Answer 1

Answer:

- 16k + 28

Step-by-step explanation:

3 - 2(k - 2) - 7(2k - 3) ← distribute parenthesis

= 3 - 2k + 4 - 14k + 21 ← collect like terms

= - 16k + 28

Answer 2

Answer:28−16k

Step-by-step explanation:

3−2(k−2)−7(2k−3)

Use the distributive property to multiply −2 by k−2.

3−2k+4−7(2k−3)

Add 3 and 4 to get 7.

7−2k−7(2k−3)

Use the distributive property to multiply −7 by 2k−3.

7−2k−14k+21

Combine −2k and −14k to get −16k.

7−16k+21

Add 7 and 21 to get 28.

28−16k

Slope intercept form

Answers

Answer:

y=-3x+1

Step-by-step explanation:

1) the slope-interception form is: y=slope*x+intercept;

2) if A(0;1) and B(2;-5) then it is possible to make up the equation of the required line:

[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}; \ => \ \frac{x}{2}=\frac{y-1}{-6};[/tex]

3) the equation in the item 2 can be written in slope-interception form:

x=(y-1)/(-3); ⇔ y-1= -3x; ⇔ y= -3x+1.

P.S. note, the suggested way of solution is not the shortest one.

What is the solution to the inequality 1 2/3 > r - 7/12

Answers

Answer:

r ≤ 2 1/4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Rewriting Fractions

Step-by-step explanation:

Step 1: Define

1 2/3 ≥ r - 7/12

Step 2: Solve for r

Rewrite: 5/3 ≥ r - 7/12

Isolate r: 9/4 ≥ r

Rewrite: r ≤ 9/4

Reduce: r ≤ 2 1/4

Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.

HELP ASAP PLEASE 100 POINTS GIVEN!!!!!!!!

Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 850 points. The number of two-point field goals that Lindsey made was 57 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 41 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season.

Answers

Given that :

Total point = 867

Let :

number of 3 point goals = p

Number of 2 point goals = 2p - 66

Number of 1 point goals = (2p - 66) - 36 = 2p - 102

Hence,

3p + 2(2p - 66) + 2p - 102 = 867

3p + 4p - 132 + 2p - 102 = 867

3p + 4p + 2p - 234 = 867

9p - 234 = 867

9p = 867 + 234

9p = 1101

p = 122.33

2 pointer = 2p - 66

2(122.33) - 66 = 178.67

1 point = 2p - 102

2(122.33) - 102

= 142.67

Given that :

Total point = 867

Let :

number of 3 point goals = p

Number of 2 point goals = 2p - 66

Number of 1 point goals = (2p - 66) - 36 = 2p - 102

Hence,

3p + 2(2p - 66) + 2p - 102 = 867

3p + 4p - 132 + 2p - 102 = 867

3p + 4p + 2p - 234 = 867

9p - 234 = 867

9p = 867 + 234

9p = 1101

p = 122.33

2 pointer = 2p - 66

2(122.33) - 66 = 178.67

1 point = 2p - 102

2(122.33) - 102

= 142.67

find f(x)=x^2-x^3,find f(-10)

Answers

Answer:

Value of f(-10) is 1100

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

f(-10) = (-10)² - (-10)³

f(-10) = 100 - (-1000)

f(-10) = 100 + 1000

f(-10) = 1100

Value of f(-10) is 1100

The sum of two numbers is 26. The first number is two more than 5 times the second number. What are
the two numbers? Define your variables. Write two equations and then solve. Be sure to write your
answer in a complete sentence!

Answers

Answer:

Let us assume the two numbers be x and y

From the above condition we can write, x + y = 26 equation 1

second condition first no x = 2 more 5 times of the second no. that is 5y + 2

then we can write, x = 5y + 2..... eqation (2)

from equation 1 x + y = 26

subtracting y from each side , x+ y - y = 26 - y

x = 26 - y

plugging this value of x in eqn. no (2 ) we get,

26-y = 5y + 2

subtracting 5y on both sides,

26 - y - 5y = 5y - 5y + 2

26 - 6y = 2

subtracting 26 from both sides,

26 -26 -6y = 2- 26

-6y = -24

eliminating minus sign from both sides,

6y = 24

dividing by 6 on both sides,

y = 24/6 = 4

substituting this value of y in equation 1 we get,

x + 4 = 26

subtracting 4 from both sides,

x = 26- 4 = 22

Step-by-step explanation:

so we solve the 2 eqns we get x = 22 and y = 4

the two numbers will be 22 and 4

pamelia is 9 years younger than jiri. The sum of their ages is 55. What is Jiris age?

Answers

Answer: 32

Step-by-step explanation: since Jiri is 9 years older, you set an equation where x (Pamelia age) + 9. So the equation is 55= x + (x+9). You subtract 9 from both sides, then divide 46 by 2 to find the Pamelia age. To find Jiri’s age, add 9 to 23 (Pamelia age).
