Answer:

(- [tex]\frac{15}{2}[/tex], 25 )

Step-by-step explanation:

Given the 2 equations

y = - 4x - 5 → (1)

y = - 2x + 10 → (2)

Substitute y = - 2x + 10 into (1)

- 2x + 10 = - 4x - 5 ( add 4x to both sides )

2x + 10 = - 5 ( subtract 10 from both sides )

2x = - 15 ( divide both sides by 2 )

x = - [tex]\frac{15}{2}[/tex]

Substitute this value into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25

Solution is ( - [tex]\frac{15}{2}[/tex], 25 )

Answer:

11 months

Step-by-step explanation:

50m + 75 >= 600

just solve the inequality like how you would solve an equation, by inverse operations and simplifying

50m + 75 >= 600

        -75       -75

50m >= 525

/50        /50

m>= 10.5

just round up, because 0.5 of a month really isn't an answer

so 11 months

Answer:

A rate of 5/2 means that:

If we move 2 units to the right, we move 5 units up.

Let's see all the graphs, the easier way to know this is:

In any point of the line, move to the right 2 units.

Then from that point, move up until you meet again with the line, if you moved 5 units, then the slope is 5/2.

A) The slope is 5/2.

B) The slope is 4/2

C) the slope is 5/2

I can not see very well graphs E and D in the image.

E) may have a slope of 5/2, you should measure it.

D has not a slope of 5/2,  you can compare it with A and see that is totally different, so you can discard option D.

Lines A and C are having a slope of (5/2) and line E may have the slope of (5/2).

Step-by-step explanation:

Given information:

Line A,B,C,D and E having different slopes;

Now as we know that equation of the line is:

[tex]y=mx+c[/tex]

where, m is the slope of the line

Now, Also [tex]dy/dx=m[/tex]

Hence, the slope of the line can also be calculated according to that.

Now, as given in the graph:

Line A is having [tex]dy=10\; \text {and} \; dx =4[/tex]

Hence slope of line A

[tex]dy/dx(A)=5/2[/tex]

Similarly:

Line B is having slope of (4/2)

Line C is having slope of (5/2)

Line D is not having slope of (5/2)

And Line E may have the slope of (5/2).

Answer:

After 11 weeks, Darnell′s savings account will have a total of $8,360.

Step-by-step explanation:

The data provided is as follows:

   n:    1        2       3        4

f (n): 260   360   460   560  

Consider the data for f (n).

The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.

The nth term of an arithmetic sequence is:

[tex]a_{n}=\frac{n}{2}[2a+(n-1)d][/tex]

Compute the value of f (11) as follows:

[tex]f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100][/tex]

        [tex]=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360[/tex]

Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

OTHER GUY IS WRONG!!!

Given that,

Each statement describes a transformation of the graph of f(x) = x.

We have to determine,

Which statement correctly describes the graph of g(x) if g(x) = -8f(x)?

According to the question,

Let, The graph f(x) = x,

Where r is the real number which is r >0.

And The graph of g(x) if g(x) = -8f(x),

The value of the r is -8.

The graph which describes the transformation of the given graph in the steps follows all the steps given below.

Hence, The graph of f(x) reflected about the x-axis and stretched vertically by a factor of 8.

Answer:

Step-by-step explanation:

a). Perimeter of the kitchen = total length of all sides

                                              = 4 + 2 + 2 + 6 + 6 + 12 + 10  (Since side of one smallest square = 2 feet)

                                              = 42 ft

   Area of the kitchen = Area of the composite figure

                                     = 4² + 2² + (6 × 12)

                                     = 16 + 4 + 72

                                     = 92 square feet

b). Perimeter of bedroom = 2(length + width)

                                          = 2(12 + 8)

                                          = 40 feet

    Area of the bedroom = Length × Width

                                         = 12 × 8

                                         = 96 square feet

c). Perimeter of the bathroom = 2(9 + 4) = 26 feet

   Area of the bathroom = 9 × 4 = 36 square feet

d). Perimeter of the closet = 2(6 + 8) = 28 feet

   Area of the closet = 6 × 8 = 48 square feet

e). Area of the hallway = Total area of the floor plan - area of the (kitchen + bathroom + bedroom + closet)

  Area of the floor plan = 20 × 20 = 400 square feet

  Area of the hallway = 400 - (92 + 96 + 36 + 48)

                                    = 400 - 272

                                    = 128 square feet

Step-by-step explanation:

The true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

A number system is defined as a system of writing to express numbers.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

The given inequality is x>-3.

The value of x should be greater than -3.

The value -3 is not included.

In a number line the values are increased from left to right.

As x is greater than -3 which means the x values are increasing from left to right.

So the statement open circle on -3 and all numbers to the right shaded is true statement.

Hence,  the true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

Answer:

Option (2)

Step-by-step explanation:

pH level of a substance is determined by the formula,

pH = - log[H+}

where [H+] is the hydrogen ion concentration

Let the [H+] ion concentration = a

a = -log[H+]

log[H+] = -a

[H+] = 1 × [tex]10^{-a}[/tex]

Here 'a' is between 7 and 14.

Which means an alkaline substance must have the concentration between [tex]1\times 10^{-7}[/tex] to  [tex]1\times 10^{-14}[/tex].

From the given options, [tex]5\times 10^{-12}[/tex] moles per liter lies in the given range.

=======================================================

Explanation:

First let's find BD

The three triangles are similar, allowing for the proportion to be set up

AD/BD = BD/DC

9/x = x/8

9*8 = x*x

x^2 = 72

x = sqrt(72)

BD = sqrt(72)

Now we can use the pythagorean theorem. Focus on triangle BDC.

The legs are BD = sqrt(72) and DC = 8. Let's find the hypotenuse

(BD)^2 + (DC)^2 = (BC)^2

(sqrt(72))^2 + (8)^2 = m^2

72 + 64 = m^2

136 = m^2

m^2 = 136

m = sqrt(136)

We can simplify this but your teacher has chosen not to. If you want to simplify, then,

m = sqrt(136)

m = sqrt(4*34)

m = sqrt(4)*sqrt(34)

m = 2*sqrt(34)

Answer:

She should get $23.6 in change

Step-by-step explanation:

You add the two items she bought which makes up $89.94, then you subtract the discount of $13.50, which leaves you with 76.44 to pay. If you pay with a 100 dollar bill, you subtract 76.44 from 100 in order to find out how much change you recieve.

Answer:

Step-by-step explanation:

100-((39.95+49.99)-13.50)=

100-(89.94-13.50)=

100-76.44=

23.56

You have to add the amount she is paying for the total then subtract that by the discount. Then subtract how much she gave them by the cost to get the change!
