You have to use PEMDAS.

$8-1*0+2/2 \\ \\ 8-0+2/2 \\ \\ 8-0+1 \\ \\ 8+1 \\ \\ 9$

$8 - (1 X 0 ) + ( \frac{2}{2} ) = 8 - 0 + 1 = 9$

Mimi sells super-sized cookies for $1.50 each and estimates she has expenses of $10 to make one batch of cookies. If the inequal

Jobisdone [24]

Answer:

(b) x > 26 cookies

Step-by-step explanation:

The selling price of 1 super-sized cookie, S.P.=$1.50

Let a batch have x cookies.

So, the selling price of x cookies=1.5x

The expences in making one batch of cookies=$10

So, net profit = 1.5x-10

The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.

As she wants to make a profit of at least $30, so for this condition, the value of y is 30.

Now, the given inequality become,

$1.5x - 10 >30$

$\Rightarrow 1.5x>30+10$

$\Rightarrow x>\frac{40}{1.5}$

$\Rightarrow x>26\frac{2}{3}$

As x is the number of cookies, so, it can't have a fractional value. This can be written as

$x>26$ or $x\geq27.$

So, she has to sell more than 26 cookies to make a profit of at least $30.

Hence, option (b) is correct.

Consider the following formula used to estimate the height, h, of a seeding after w weeks since planting h=(1/5)w + (8/5)which o

Bogdan [553]

Answer:

w=5h-8

Step-by-step explanation:

Take the original formula h=(1/5)w+(8/5)

Subtract -8/5 on both sides to isolate the w, so h-8/5=(1/5)w

Now you have to get rid of the 1/5, so multiply 5(h-8/5), the 5 in the 8/5 cross each other out. You are left with 5h-8

Rearrange then factorise x^2-5x+19=5x+3

Tema [17]

Answer:

x = ±4i or x = ±√-16

Step-by-step explanation:

x² - 5x + 19 = 5x + 3

x² + 16 = 0

x² = -16

x = ±√-16 (a negative square root is an imaginary number)

The coordinates (-2, -2.5) and (-1, -1) are satisfying the equation so pairs (A) and (B) will be correct.

<h3>What is the equation?</h3>

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

Given the equation,

3x= 2y - 1

To know which coordinate satisfies the equation we need to put one by one all three coordinate,

Coordinate (A) ⇒ A) (-2, -2.5)

3(-2) = 2(-2.5) - 1 ⇒ -6 = -6 so it is satisfying.

Coordinate (B) ⇒ B) (0, -0.5)

3(0) = 2(-0.5) - 1 ⇒ 0 ≠ -2 so it is not satisfying.

Coordinate (C) ⇒C) (-1, -1)

3(-1) = 2(-1) - 1 ⇒ -3 = -3 so it is also satisfying.

Hence "The pair (-2, -2.5) and (-1, -1) are satisfying".
