Answer:

[tex]y = -\frac{1}{4}x +2[/tex]

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (-4, 3), (0, 2)

(0, 2) = (x1, y1)

(-4, 3) = (x2, y2)

To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the formula used to find slope:

[tex]\frac{3-2}{-4-0}[/tex]

Simplify:

3 - 2 = 1

-4 - 0 = -4

[tex]\frac{1}{-4}= -\frac{1}{4}[/tex]

The slope is [tex]-\frac{1}{4}[/tex].

To find the y-intercept, input the slope and one of the given points(in this example I'll use point (0, 2)) into the equation and solve for b:

[tex]2 = -\frac{1}{4} (0)+b[/tex]

2 = 0 + b

2 = b

The y-intercept is 2.

Now that we know the slope and the y-intercept, we can write the equation:

[tex]y = -\frac{1}{4}x +2[/tex]

Answer:

No they are not perpendicular.

Step-by-step explanation:

No they are not because they are both line b is still negative.

In order for them to be perpendicular is if the slopes were like this....

-4/3x and 3/4x

or

4/3x and -3/4x

They have to be complete opposites.

Answer:The length of one side would be 11

Step-by-step explanation:

Answer:

11 cm

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( where s is the side length )

Here A = 121 , then

s² = 121 ( take the square root of both sides )

s = [tex]\sqrt{121}[/tex] = 11

Answer:

m = 1/2

Step-by-step explanation:

Slope(m) = (y-y1)/(x-x1)

= (-1 - (-2))/(1 - (-1))

= (-1+2)/(1+1)

= 1/2

Answer:

y=3x-4

Step-by-step explanation:

a slope of 3 means that the equation will definitely start like this

y=3x +/- b

to find b, substitute the coordinates given, so

5=3 x 3 +/- b

5=9 +/- b

5-9=b

-4=b

so the equation would be

y=3x-4

Step-by-step explanation:

Subtraction is just like addition. How much do you need to make 0.18 0.62? then you have your answer. This is just a strategy.

Answer:

B.)

Step-by-step explanation:

A rational number is a number with no repeating decimals or decimals that go on “forever” like pi.  An expample of a rational number is 2 where 2.3333333... is not a rational number.  Pi isn’t a rational number either since forth there is no known end to that.  

So, when solved:

A.) = 1.58113883...  (irrational)

B.) = -8 (rational)

C.) = 8.94427191... (irrational)

D.) = 3.794733192... (irrational)

I hope you see the pattern.  Hope this helps!

Answer:

1) (x - 9)(x + 2)  ==> trinomials

2) (s + z) (3m - 2n)  ==> factorising by parts

3) (x + 2)(5x + 3)  ==> factorising with a leading coefficient

4) 9y²(3y² - 2)  ==> GCF

5) (4m - 12)(4m + 12)  ==> DoPS

Step-by-step explanation:

1). Find multiples of -18 that add up to -7

Multiples of -18 : (only one number can be negative, because positive*negative = negative)

1, 18 or 3, 6 or 2, 9

Only one pair adds up to -7 which is -9 + 2

Hence ==> (x - 9)(x + 2)

2). Find the common things between the terms and factorise it out  

3m(s + z) - 2n(s + z)

Since the terms inside the brackets are the same, you simplify it to:

(s + z) (3m - 2n)

3). Multiply the first coefficient with the last coefficient: 5(6) = 30

Find two numbers that multiply to 30 and add up to the middle coefficient -13.

Multiples of 30 are: 1, 30 or 2, 15 or 3, 10 or 5,6, but only one pair would add to -13 and that is 3 and 10

So the next step is to write it in this form: 5x² + 10x + 3x + 6

Factorise: 5x(x + 2) + 3(x + 2)

(x + 2)(5x + 3)

4). Find the greatest common factor within 27y⁴ and 18y², which is 9y²

9y²(3y² - 2)

5). Square root each number: √16 = 4 and √144 = 12

(4m - 12)(4m + 12)

Answer:

[tex]\frac{7}{8}[/tex]

Step-by-step explanation:

To find the total amount of flour and sugar, you have to find a common denominator for the two fractions and then add them together.

[tex]\frac{1}{2}[/tex] multiplied by 4 equals [tex]\frac{4}{8}[/tex].

Now that the fractions both have a common denominator of 8, we can add them together:

[tex]\frac{3}{8}[/tex] + [tex]\frac{4}{8}[/tex] = [tex]\frac{7}{8}[/tex]

The total amount of flour and sugar is [tex]\frac{7}{8}[/tex]

Answer:

combined feet of shelving = 8.435 feet

Step-by-step explanation:

To find the combined feet of shelving, we simply add the two lengths of the shelvings:

1. white plastic shelf = 6.35 feet long

2. brown plastic shelf = 2.085 feet long

combined feet of shelving = 6.35 + 2.085 = 8.435 feet

Answer:

2x = 12

3. Divide both sides by 22.

x = 12/2

4. Simplify 12/2 to 6

x = 6

Answer:

Step-by-step explanation:

The expression "[tex]y = 4x^2[/tex]" is a vertical stretch of the parent function f(x) = [tex]x^2[/tex].

What is the functions?

Functions are mathematical relations that describe the relationship between inputs (often called "input values" or "arguments") and outputs (often called "function values" or "results").

The vertical stretch of the parent function f(x) =[tex]x^2 \\[/tex] can be identified by the coefficient multiplied with the squared term.

Among the given options:
