7th grade math help me plzz

Answer:

y=-3x-1

Step-by-step explanation:

The mistake that was made was in the denominator of the work. The second 2 should be the -1. This is what you should get:

[tex]\frac{-7-2}{2-(-1)}[/tex]

[tex]\frac{-9}{3} =-3[/tex]

Hope that clear things up.

Answer:

Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.

5+3−2=6+2−2

This gives us a couple of properties that hold true for all equations.

The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation

ifa−b=c,thena−b+b=c+b,ora=c+b

The same goes with the subtraction property of equality.

ifa+b=c,thena+b−b=c−b,ora=c−b

As well as it goes for the multiplication property of equality. If you multiply each side of an equation with the same nonzero number you produce an equivalent equation.

ifab=c,andb≠0,thenab⋅b=c⋅b,ora=cb

And naturally this goes for the division property of equality as well. You can divide each side of an equation with the same nonzero number to produce an equivalent equation

ifa⋅b=c,andb≠0,thena⋅bb=cb,ora=cb

This gives us a way to change an equation to our own liking. Anything is acceptable as long as you do the same thing on both sides.

so pretty much what I'm tryna say it x=4

Hello your question has some missing part below is the missing part

The Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United States. For 15 restaurants located in Boston, the average price of a dinner, including one drink and tip, was $48.60. You are leaving for a business trip to Boston and will eat dinner at three of these restaurants. Your company will reimburse you for a maximum of $50 per dinner. Business associates familiar with these restaurants have told you that the meal cost at one-third of these restaurants will exceed $50. Suppose that you randomly select three of these restaurants for dinner.

Answer : 0.2637

Step-by-step explanation:

Average price of dinner including one drink and a tip in Boston = $48.60

Number of restaurants = 15

number of restaurants whose meal cost more than $50 = 1/3 * 15 = 5

Probability that None of the meals will exceed the cost covered by your company

ATTACHED BELOW is the solution

P( none ) = 0.2637

Answer:

Equal

Step-by-step explanation:

9.90 = 9.9

The difference is just decimal places

Evaluating the two values, both numbers 9.90 and 9.9 are equal.

Hence, the values 9.90 and 9.9 are equal.

Answer:

  1/8 lb or 2 oz

Step-by-step explanation:

You find the weight per egg by dividing the weight by the number of eggs:

  (3/4 lb)/(6 eggs) = 3/24 lb/egg = 1/8 lb/egg

A pound is 16 ounces, so 1/8 lb is 2 oz.

Each egg weighs 1/8 lb or 2 oz.

Answer:

x(x³ + 2)(3x - 7)

Step-by-step explanation:

I got it right

The solution is Option D.

The equation is simplified as A = x ( 3x⁴ - 7x³ + 6x - 14 )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 3x⁵ - 7x⁴ + 6x² - 14x   be equation (1)

Now , on factorizing the equation , we get

Taking the common factor as x in the equation , we get

A = x ( 3x⁴ - 7x³ + 6x - 14 )

Therefore , the value of A is x ( 3x⁴ - 7x³ + 6x - 14 )

Hence , the equation is A = x ( 3x⁴ - 7x³ + 6x - 14 )

Answer:

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides. For example, if one of the other sides has a length of 3 (when squared, 9) and the other has a length of 4 (when squared, 16), then their squares add up to 25. The length of the hypotenuse is the square root of 25, that is, 5.
