1.) Given the equation y = 4x + 7, what is the slope of the line?

a.) 7
b.) 4
c.) -7
d.) Not enough information
----------------------------------------------------------------------------------------------------------
2.) Given the equation y = 4x + 7, which of these points is on the line?

a.) (4, 7)
b.) (4, 0)
c.) (0, 7)
d. (0, 4)

Factor 12 × 2+ 4=28

Factor x2-7x+12=(x-3) (x-4)

Answer:

x = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x + 29 (x − 3) = 7x − 6

5x + (29) (x) + (29) (−3) = 7x + −6 (Distribute)

5x + 29x + −87 = 7x + −6

(5x + 29x) + (−87) = 7x − 6 (Combine Like Terms)

34x + −87 = 7x − 6

34x − 87 = 7x − 6

Step 2: Subtract 7x from both sides.

34x − 87 −7x = 7x −6 −7x

27x − 87 = −6

Step 3: Add 87 to both sides.

27x − 87 + 87 = −6 + 87

27x = 81

Step 4: Divide both sides by 27.

27x/27 = 81/27

x = 3

Hope it helps!!

Answer:

x=1

Step-by-step explanation:

subract 4.3 from both sides. add x to both sides. divide by 2.2 from both sides

The solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.

Given is an equation 1.2x + 4.3 = 2.1 - x, we need to solve for x,

To solve the equation 1.2x + 4.3 = 2.1 - x, we can follow these steps:

1. Combine like terms on both sides of the equation:

1.2x + x = 2.1 - 4.3

2. Simplify the equation:

2.2x = -2.2

3. Divide both sides of the equation by 2.2 to isolate x:

x = -2.2 / 2.2

4. Simplify the right side of the equation:

x = -1

Therefore, the solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.

Step-by-step explanation:

1. A = 68

B = 112

c = 68

2. A = 127

3. A = 70

B = 55

C = 25

Answer: 55

Step-by-step explanation:

M + (3n - 5)² = 6 + (3 x 4 – 5)^²

* 6 + (7)²

* 6 + 49 = 55

Sorry if the other answer misleads you. Here is the real answer!

The answer to the expression m +(3n - 5)² is 55.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

m +(3n - 5)²

Now, put the value of m= 6 and n= 4 we get

m +(3n - 5)²

= 6 +(3(4) - 5)²

= 6 +(12 - 5)²

= 6 +(7)²

= 6+ 49

= 55

Hence, the answer is 55.

Step-by-step explanation: How to Convert a Number to Scientific Notation

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

Answer:

The equation representing the relationship between x and y is that;

4y = 3x

Step-by-step explanation:

Here, we want to write a relationship.

From the question, we are told that the amount donated by the family which is x dollars is proportional to what local businesses gave.

From the question, there was an example in which a family gave $12 and local businesses gave $9

So let us establish a relationship using ratio of x to y

Thus;

12/9 = x/y

12y = 9x

4y = 3x

Answer:

y=-3x-10.5

Step-by-step explanation:

Let's use the first set of numbers.

-7.5 and 12

-3.5 and 0

Our rise here is -12 and run is 4.  So, our slope is -3.

Now we just need our intercept.

y = mx + b

y = -3x + b

0 = -3(3.5) + b

b = -10.5

The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

The table represents some points on the graph of a linear function.

 х           у

-7.5        12

-3.5        0

  -1       -7.5

  2       -16.5

3.5       -21

Take two points from the table, then the points are (-7.5, 12) and (-3.5, 0). Then the equation of the line is given as,

y - 0 = [(-3.5 + 7.5) / (0 - 12)](x + 3.5)

y = - (1/3)(x + 3.5)

3y = - x - 3.5

x + 3y + 3.5 = 0

The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.

Answer :

Width : 9

length: 3.6

The perimeter will be 25.2

-----------------------------------------------------------------------------------------------------------------

Show your work : Since the length and width are 3 times bigger have to multiply the old one by 3

so 1.2  times 3 = 3.6

so 3 times 3 = 9

thats the length

to find the perimeter its 2L + 2W

2(3.6) + 2(9)=25.2
