Answer:

how to solve 2x+2y=2 , -4x+4y=12

this is  solving equations using substitution .... i have ALOT more but i juss dnt get this stuff

2x + 2y = 2      -4x + 4y = 12

x + y = 1

x = 1 - y

-4x + 4y = 12

-4(1 - y) + 4y = 12

(-4 + 4y) + 4y = 12

-4 + 8y = 12

8y = 16

y = 2

2x + 2y = 2

2x + 2(2) = 2

2x + 4 = 2

2x = -2

x = -1

Check.

-4x + 4y = 12

-4(-1) + 4(2) = 12

4 + 8 = 12

Answer: x = -1 and y = 2

Answer:

4 is the slope

Step-by-step explanation:

y−6=4(x+5)

This equation is in point slope form

y -y1 = m(x-x1)  where m is the slope and ( x1,y1) is a point on the line

4 is the slope and ( -5,6) is a point on the line

Answer:  if im correct it should be 9,000 words because you have to multiply 7.5 by 60 because you have to convert it to seconds and then you multiply 20 by 450 ( 7.5 * 60 = 450 ) and then you would have 20 * 450 = 9,000

Step-by-step explanation:

so therefore mark jogged 2 36/70km more than his sister

The number of kilometers that Mark jog more than his sister will be 32 / 35 km.

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.

Mark jogged 3 ⁵/₇ km. His sister jogged 2 ⁴/₅ km.

Convert the mixed fraction number into a fraction number. Then we have

3 ⁵/₇ = 3 + 5/7 = 26/7

2 ⁴/₅ = 2 + 4/5 = 14/5

Then the number of kilometers that Mark jog more than his sister will be given as,

⇒ 26/7 - 14/5

⇒ 32 / 35 km

The number of kilometers that Mark jog more than his sister will be 32 / 35 km.

The vertex of the absolute function g(x) = |x|- 8 lies at (0,-8).

The absolute value or modulus of a real number x, denoted by |x|, is its non-negative value regardless of its sign.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the absolute function is g(x) = |x| - 8. The vertex will be calculated by plotting the function on the graph.

From the graph, the vertex of the absolute function lies at the point ( 0,-8). The graph is attached with the answer below.

Answer: Length = 35

Width = 21

Step-by-step explanation:

From the question, we are informed that the area of a rectangle is 735 in squared and that the ratio of the length to the width is 5 : 3.

To find the length and the width of the rectangle goes thus. We should note that the area of a rectangle is the length multiplied by the width.

Therefore, 5x × 3x = 735

15x² = 735

x² = 735/15

x² = 49

x = ✓49

x = 7

Recall that length = 5x = 5 × 7 = 35

Width = 3x = 3 × 7 = 21

Answer: 40%

Step-by-step explanation:

6/15 = 0.4 = 40%

Answer:

40%

Step-by-step explanation:

Since there are 15 fruites, and 6 of them are apples,

then, 6/15 of all the fruites are apples.

Converting 6/15 in a percentage, we get:

6/15 = 0.4 = 40%

Answer:

2x^2+23.

Step-by-step explanation:

Combine like terms.

This expression simplified is 2x^2+23.

Answer and explanation:

Given that initial population of fruit flies = 4

And population of fruit flies triple every week

If population of fruit flies triple every week then let x represent number if weeks

Therefore function can be modelled thus :

f(x)= 4 + 3x

To demonstrate that the function is correct, we use an example. Now assume population grows for two weeks, using the function:

f(2)= 4+3×2

f(2)= 10

Therefore population grows to 10 fruit flies in 2 weeks based on our function

Answer (assuming the question allows it to be written in slope-intercept form):

[tex]y = -\frac{3}{5} x-\frac{9}{5}[/tex]

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the given points' x and y values, and simplify:

[tex]m = \frac{(-3)-(0)}{(2)-(-3)} \\m =\frac{-3-0}{2+3}\\m = -\frac{3}{5}[/tex]

Thus, the slope is [tex]-\frac{3}{5}[/tex].

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:

[tex]y-(-3) = -\frac{3}{5} (x-(2))\\y + 3 = -\frac{3}{5} x + \frac{6}{5} \\y = -\frac{3}{5} x - \frac{9}{5}[/tex]
