One winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F. What is the temperature at its coldest point? Describe how you would find your answer on a number line.

The Answer: x = -2/7

Answer: x = 2/7 or 0.29

Step-by-step explanation:

- 2x - 12 = 5x - 10

- 2x - 5x = 12 - 10

- 7x = 2

x = 2/7 or x = 0.29

The decimal place is rounded up.

Answer:

100

Step-by-step explanation:

Round off each number to 1 significant figure first.

(39×52)/(3.8×4.9) = (40×50)/(4×5)

Evaluate numbers in brackets.

(40×50)/(4×5) = 2000/20

Evaluate.

2000/20 = 100

The value of the expression will be equal to 100.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Round off each number to 1 significant figure first.

(39×52)/(3.8×4.9) = (40×50)/(4×5)

Evaluate numbers in brackets.

(40×50)/(4×5) = 2000/20

(40×50)/(4×5)  = 2000/20 = 100

Therefore, the value of the expression will be equal to 100.

Answer:

A. 24  

Step-by-step explanation:

If we have two digits to multiply together, the multiplication of the individual digit of those number with each other whereby each digit retain its place is known as partial product.

From the given question, by applying the distributive property method, the partial products are:

24 × 69 = 24 × (60 + 9)  

open brackets

= (24 × 60) + (24 × 9)

By factorization

= 60 (20 + 4) + 9(20 + 4)

expanding the brackets, we get:

= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)

= 1200 + 240 + 180 + 36   (These are the partial products)

= 1656

Answer:

60%

Step-by-step explanation:

Let the total number of people polled to vote be 1000

80% said they would vote for him

That is 800

20% said they would not vote for him

That is 200

Out of the 800, 70% actually voted

That will be ;

70/100 * 80 = 560

Also, 20% of the 200 that said they would not vote actually voted

That will be ;

20/100 * 200 = 40

Total is thus;

569 + 40 = 600

% is 600/1000 = 60%

Step-by-step explanation:

The equation y = (x + 2)² + 3 represents the shown parabolic graph. The correct answer is option B.

The vertex of the parabola occurs at the point (-2, 3), which is the point where the parabola reaches its minimum value.

The term (x + 2)² indicates that the parabola is translated horizontally by 2 units to the left from the standard vertex form of a parabola.

The "+3" term indicates that the parabola is translated vertically by 3 units upward.

Hence, the equation y = (x + 2)² + 3 represents the shown parabolic graph.

Thus, the correct answer is option B.

Explanation:

The result of problem 7 is undefined because the matrices are not the same size. Both matrices must have the same number of rows, and they must have the same number of columns. This is so the terms match up when we add them. This applies to question 9 as well because subtraction is a form of addition.

For problem 8, we add the corresponding terms. So for instance, along the top we have -2+(-3) = -5 as the first entry in the top row. So that's why the answer is C for problem 8. Problem 10 and 11 are similar to this. Be careful to distribute the negative through to each term in the second matrix when subtracting matrices.

For problem 12, we multiply the outer 3 by each term inside the matrix. We end up with choice B.

The value of x that makes the equation true 12/x = 8/6 is 9

Two or more expressions with an Equal sign is called as Equation.

We need to find the value of x that makes the equation true 12/x = 8/6

The given equation is 12/x=8/6

Twelve divided by x equal to eight by six

Apply cross multiplication

12(6)=8x

72=8x

Divide both sides by 8

x=9

Hence, the value of x that makes the equation true 12/x = 8/6 is 9

Step-by-step explanation:

Answer:

The value of the coin when Consuelo originally purchased it is $9.74 ⇒ C

Step-by-step explanation:

The form of the linear equation is;

y = m x + b, where

m is the slope of the line (The rate)

b is the y-intercept (initial amount, value y at x = 0)

∵ The value of a collectible coin can be represented by the equation

  y = 2 x + 9.74

→ Compare it with the form of the linear equation above

∴ m = 2

∴ b = 9.74

∵ x represents the number of years that Consuelo has owned the coin

∵ y represents the total value, in dollars, of the coin

→ That means the value of y at x = 0 is the value of the coin when

  Consuelo originally purchased it

∵ b represents the value of y at x = 0

∵ b = 9.74

∴ The value of the coin when Consuelo originally purchased it is $9.74

Answer:

y=2x-10
