Answer:

x = -4

Step-by-step explanation:

2(3x + 7) = -49 + 39

6x + 14 = -10

6x = -10 - 14

6x = -24

x = -4

The equation showing the variation of the temperature would be y=(23x) + 68.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that A chef preheats an oven. It starts at room temperature, 68°F, and heats up to 23°F per minute.

The equation will be written as:-

y = 23x + 68

Here x is the time of preheating.

Therefore, the equation showing the variation of the temperature would be y=(23x) + 68.

Answer:

The coordinates of the original point would be (-9,4). This is because, by reflecting over the way y-axis, the point is moving across the x-axis and therefore, makes the x-coordinate negative.

Answer:

4/16 ( 1 + 11) = 3

could be many answers as fractions see below

The last fraction seems more likely out the three or make it harder fraction.

Step-by-step explanation:

1/2 (2 + 4) = 3  as 1/2 of 4 is 2            1+2 = 3  

or

1/4 (4 + 8) = 3   as 1/4 of 8 is 2           1+2 = 3

or

3/4 ( 2 + 2) = 3   as 3/4 of 2 is 1 1/2   1.5 + 1.5 = 3

or harder fraction

4/16 ( 1 + 11) = 3

Answer:

25 - n

Step-by-step explanation:

n is a variable. It can represent any number. For example, 5 years ago, Mario would be 20 years old since 25-5 is 20.

So, if n is 8, you have to do 25 - 8 to find the answer to how old Mario was 8 years ago.

So his age n years ago, is 25 - n.

The point of intersection of y = 2x – 3 and y = 1 is (2,1).

Here, we have,

given that,

the equations are:

y = 2x – 3 ....1

and y = 1 .....2

now, we have to solve them.

so, putting the value of y from 2, in 1,

we get,

2x – 3 = 1

or, 2x = 4

or, x = 2

so, we have,

Answer:

Part A

The Quadratic Function to model the total number of bricks the stack is f(x) = x²

Part B

The number of bricks we will have for 50 rows is 2500 bricks

Step-by-step explanation:

Part A

Let the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = a·x² + b·x + c

We have;

When x = 0, f(x) = 0, therefore, f(0) = a×0² + b×0 + c = 0 + 0 + c = 0

∴ c = 0

When x = 1, f(x) = 1, therefore, f(1) = a×1² + b×1 + 0 = 1

∴ a + b = 1...(1)

When x = 2, f(x) = 4, therefore, f(2) = a×2² + b×2  = 4

∴ 4·a + 2·b = 4...(2)

Multiply equation (1) by 2, and subtract it from equation (2) gives;

4·a + 2·b - 2×(a + b) = 4 - 2 × 1

2·a = 2

a = 1

From equation (1), we have;

b = 1 - a = 1 - 1 = 0

b = 0

∴ f(x) = a·x² + b·x + c = 1·x² + 0·x + 0 = x²

Therefore, the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = x²

Part B

If there are 50 rows in the stack, then we have, x = 50

Therefore;

f(50) = 50² = 2500

The number of bricks we will have for 50 rows is f(50) = 2500 bricks

Answer:

w = 21 feet

Step-by-step explanation:

The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Let's say the length of a rectangle is L while the width is W.

According to the given, L = 3W - 5

The perimeter of the rectangle is given as 2( length + width)..

Perimeter = 2(L + W)

2(3W - 5 + W) = 158

4W - 5 = 79

W = 21 feet.

Hence "The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet".

Answer:

Step-by-step explanation:

f(x) = 2x⁴ - 5x³ + 7x - 3

f(2) = 32 - 40 + 14 - 3

f(2) = 3

Answer:

y = - x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept

y = 4 - x , that is y = - x + 4 ← in slope- intercept form

with slope m = - 1

The slope crosses the y- axis at (0, 1 ) ⇒ c = 1

y = - x + 1 ← equation of parallel line
