Error Analysis: Isabel says that the equation x-2=-(x-2) has no solution because a number can never be equal to its opposite. Explain the error Isabel made. "MP.3"

Look for Relationship: You are solving an equation with a variable on each side. Does the side on which you choose to isolate the variable affect the solution? Why might you choose one side over the other? "MP.7"

Answer:

1. The factored form of the given expression is (x+7)(x+6).

2. What is the expression in factored form . 9x^2 -4

Step-by-step explanation:

1.  The given expression is,

The degree of the expression is 2, the constant term is 42, and the coefficient of x is 13.

Use factoring by grouping method

To find the factor form, we have to find two numbers whose sum is 13 and whose product is 42.

The factors of 42 are,

From which the sum of 6 and 7 is 13.

So We can write the 13x as 7x+6x.

2. This expression can be factorized using the difference of squares which can be illustrated as follows:

A^2 - B^2 = (A+B)(A-B)

In the given example:

sqrt(9x^2) = 3x

sqrt(4) = 2

and the two squares are separated by a negative sign

Therefore, the difference of squares is applicable

Based on this, factoring the given expression would give us:

9x^2 - 4 = (3x+2)(3x-2)

Answer: The cost of each baseball cap = $15.

Step-by-step explanation:

Let x = cost of each baseball cap

Given; cost of each baseball jersey= $45

Total coast of 3 baseball caps and 1 baseball jersey = $90

i.e. [tex]3x+45=90[/tex]

[tex]\Rightarrow\ 3x=45\\\\\Rightarrow\ x=\dfrac{45}{3}\\\\\Rightarrow\ x= 15[/tex]

Hence, the cost of each baseball cap = $15.

Step-by-step explanation:

Answer:

0.04 or 1/25

Step-by-step explanation:

If x = -2, then the equation is f(-2) = 5^-2

5^-2 is 0.04 so,

f(-2) = 0.04 or 1/25

Answer:

  E.  40 and 33

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the areas of the smaller squares will match the area of the largest square.

The answer choices have sums of ...

  A: 76; B: 73; C: 96; D: 66; E: 73

So, choices with the correct sum are B and E.

If this question asks you to "choose all that apply," then B & E will be your answer choices.

__

We note that the areas of the smaller squares appear to be not much different in size. If their areas were 23 and 50, the smaller square would be less than half the size of the larger one. So, if the figure is drawn approximately to scale, the choice of 40 and 33 is a better choice.

Step-by-step explanation:

H(8) means to replace x with 8 then solve:

2x -3 = 2(8) -3 = 16-3 = 13

H(8) = 13

Answer:

-2

Given:

h(x) = -9

Step-by-step explanation:

h(x) = 4x - 1

-9 = 4x - 1

-9 + 1 = 4x

-8 = 4x

-8/4 = x

x = -2

hope you understood❤

The solution for x when h(x) = -9 is -2

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively

Given;

h(x) = 4x – 1...(1)

h(x) = -9

Substituting the value of h(x) in equation 1

-9=4x-1

-9+1=4x

-8=4x

x=-8/4

x=-2

Therefore, the solution for the equation will be x=-2
