General Formulas and Concepts:
Number lineStep-by-step explanation:
Negative numbers are always going to be the smallest while positive numbers will be the greatest
Answer:
4,0,-3,-6
Step-by-step explanation:
integer means a number which is not a fraction. So 4 is the greatest ,because it is positive.Then 0.Then -3 then -6 'cause there negative.
You are baking a cake, and the recipe calls for 3/8 of a cup of flour and 1/2 of a cup of sugar. What is the total amount of flour and sugar, as a reduced fraction?
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]
Hope this helps :)

if xy=5 and x square +y square =25 ,then (x+y)square
Answer:
(x + y)² = 35
Step-by-step explanation:
The expansion of
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy ← substitute given values
= 25 + 2(5)
= 25 + 10
= 35
Answer:
35
Step-by-step explanation:
[tex]xy = 5 \\ \\ {x}^{2} + {y}^{2} = 25 \\ \\ \because \: {(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy\\ \\ \therefore {(x + y)}^{2} = 25 + 2 \times 5 \\ \\ \therefore {(x + y)}^{2} = 25 + 10 \\ \\ \huge \red{ \boxed{\therefore {(x + y)}^{2} = 35}}[/tex]

F $71.43 G $60.00 H $51.23 J $8.75
Answer:
Option F: $71.43 is the correct answer.
Step-by-step explanation:
By the question we can observe that 35% of regular price is $25 so this information will be used to calculate the original price of the shoes.
Let
P be the price of shoes
and d be the discount
So
[tex]d = \$25\\P=?[/tex]
The discount is 35% of P so
[tex]d = 35\%\ of\ P\\25 = 0.35 * P\\P = \frac{25}{0.35}\\P = 71.42857...[/tex]
Rounding off to the nearest hundredth
The regular price is: $17.43
Hence, option F: $71.43 is the correct answer.

Two people enter a whispering gallery and want to know where they should stand so they can hear the other person's whisper. The gallery is 100 feet wide and the vertical distance from their head to the peak of the ceiling is 30 ft.
Answer:
The two people should stand 40 feet from the center so that they can hear each other whisper
Step-by-step explanation:
From the question
Width of the gallery = 100 feet
Width = 2a
a = Width/2
a = 100/2 = 50 feet
Height of the gallery = b = 30 feet
Hence, the distance is
d² = a² - b²
d = √a² - b²
d = √50² - 30²
d = √2500 - 900
d = √1600
d = 40 feet
Hence, the two people should stand 40 feet from the center so that they can hear each other whisper.

Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 1 + x + 14 + 4x + 5 = 180, that is
8x + 20 = 180 ( subtract 20 from both sides )
8x = 160 ( divide both sides by 8 )
x = 20

write an equation in slope intercept form that passes through the points (-4,3) and (0,2)
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]
Name the type of factoring (DoPS, GCF, Trinomials, factoring by parts, factoring with a leading coefficient)
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)

Which of the following is a vertical stretch of the
parent function f(x)=x^2
y=4x^2
y=1/4+x^2
y=(1/4x)^2
y = x^2-4
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:
y = [tex]4x^2[/tex] - This is a vertical stretch of the parent function f(x) = [tex]x^2[/tex] by a factor of 4, which means the graph of the function is stretched vertically by a factor of 4.y =[tex]1/4 + x^2[/tex] - This is a vertical shift and addition of a constant to the parent function f(x) = [tex]x^2,[/tex] but not a vertical stretch.y = [tex](1/4x)^2[/tex] - This is not a vertical stretch of the parent function f(x) = [tex]x^2[/tex]. It involves a reciprocal and squaring operation on x, but not a vertical stretch.y = [tex]x^2 - 4[/tex] - This is a vertical shift and subtraction of a constant from the parent function f(x) = [tex]x^2[/tex], but not a vertical stretch.Hence, the correct option that represents a vertical stretch of the parent function f(x) =[tex]x^2[/tex] is y = [tex]4x^2[/tex] (Option 1).

A line with a slope of 3 passes through (2,5). Which choice is an equation of this line?
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
