The total amount Daria spent on all her purchases is $100

In order to determine the total amount Daria spent on all her purchases, the cost of each item has to be added together.

Addition is a mathematical operation that can be used to determine the total sum of two or more values. other basic mathematical operations are subtraction, multiplication and division.

Total amount spent = cost of a skein of alpaca yarn +  cost of a skein

of angora yarn + cost of a skein of wool  yarn +   cost of a pair of knitting

needles

$47.50 + $32.14 + $16.50 + $3.86 = $100

Answer:  See the worksheet below. Hope you can see.

Step-by-step explanation:

Roots: where the parabola intersects the x-axis

Axis of symmetry: the line that runs along the vertex of the parabola

Vertex: the points at which the parabola changes direction

Intercept: the point where the line intersects the y axis

Domain: the values of x (lowest to highest)

Range: the values of y (lowest to highest)

Answer:-3/4

Step-by-step explanation: Raises 3 units, goes to the left 4 units.

Answer:

-3/4

Step-by-step explanation:

Slope is rise over run. The line is negative as the line is falling, not rising. From one point to the next it falls 3, or rises -3. It runs 4, therefore the rise/run, or slope is -3/4.

Answer:

x=0.8712, y=1.1818

Step-by-step explanation:

1.2x+1.4y=2.7 --(1)

0.4x-0.3y=0.9--(2)

1.2x=2.7-1.4y

x=(2.7-1.4y) / 1.2 --(3)

substitute (3) in (2)

[tex]0.4(2.7-1.4y) / 1.2 -0.3y=0.9[/tex]

[tex](1.8 - 0.56y) \frac{1}{3} - 0.3y = 0.9[/tex]

times both sides with 1/3

[tex] \frac{1}{3} (1.08 - 0.56y( \frac{1}{3} ) - 0.3y = 0.9)[/tex]

1.08-0.3=0.56y+0.1y

0.78=0.66y

y=1.1818

substitute y in (3)

x=2.7-1.4(1.1818) /1.2

x=0.8712

Answer:

to get rid of the fraction multiply both sides by six

Answer:

multiply both sides by 6

Step-by-step explanation:

you won't add 2 until you have a whole number, not a fraction.

You don't need to change the direction

and you aren't supposed to change the =, >, <, or any of those signs ever, until you get to where you are multiplying or dividing by a negative number

Answer: C

Step-by-step explanation: You have to graph the 2 points and plug in each answer until the slope passes through

The required coordinate of the point K is (13, 8).

Given that,
The coordinates of point J are (-7, 2), and the midpoint of JK is at L (3, 5), the coordinates of point K is to be determined.

Coordinate, is represented as the values on x-axis and y-axis of the graph.

here,
The coordinate of the midpoint (x, y) is given as,
x = (x₁ + x₂)/2     ; y = (y₁ + y₂)/2
Substitute the value in the above equation,
3 = (-7 + x₂)/2     ; 5 = (2 + y₂)/2
x₂ = 13                ; y₂ = 8

Thus, the required coordinate of point K is (13, 8).

plug it into the slope formula m= y2 - y1 / x2- x1

it doesn't matter what way you plug them in

m = slope

m = 60-40 / 50 - 20 = 20/30 = 2/3

The slope is 2/3 I simplified 20/30 by dividing by 10

Answer:

( x - 8 ) ( x + 4 )

Step-by-step explanation:

( x - 8 ) ( x + 4 )

Answer:

steps below

Step-by-step explanation:

1) f(x) = (-3ax⁴ + ax² +x) / (2x⁴ + x³ - ax² + 8x) ... degree of the denominator = degree of the numerator       (-3a) / 2 = 5 / 4

-12a = 10

a = - 5/6

2) 3-n > n+ 10  ... degree of the denominator < degree of the numerator

   2n < -7

   n < - 3.5

The largest inter value is -4

3) f(x) = (x²+3x-4) / (2x²+7x-10)

   f(2) = (2²+3*2-4) / (2*2²+7*2-10) = 6 / 12 = 1/2

   x->∞ : divide x² both numerator and denominator, any number/ x -> 0

   f(x) = (1 + 3/x - 4/x²) / (2 + 7/x - 10/x) = (1 + 0 - 0) / (2 + 0 - 0) = 1/2

   [tex]\lim_{x \to \infty} f(x) = f(2)[/tex] = 1/2

Answer:

A) 8/9

Step-by-step explanation:

8 divided by 9 is 0.88888888888888888888889 on a calculator

The fraction that is equal to 8/9. Then the correct option is A.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

⇒ 0.8888...

Convert the decimal number into a fraction number, then we have

Let x = 0.8888..., then

10x = 8.888....

10x - x = 8.8888.... - 0.8888...

9x = 8

x = 8/9

The fraction that is equal to 8/9. Then the correct option is A.
