1. Change each of the following equations to the form
y = mx + c. Then, state the values of m and c.
(a) -6x- y = 3
(b) 3x - 4y = 12
(c)-2x + 5y = 10
(d) x + 2y = 4
(e) 8x- 4y = 3
(1) 4x + 5y = -6​

Answer:

1/3

Step-by-step explanation:

We use the formula y2-y1/x2-x1. The two points that I would use are (3,-1) and (-3,-3). This means that the equation will be -3--1/-3-3. This is equal to -2/-6. This is also equal to 1/3. Therefore, the slope is 1/3.

Answer:

this is the answer to the question, its 5.6 for sure

Answer:

Hello!

A' is (-4, 0)

B' is (-1, 4)

C' is (-1, -3)

Step-by-step explanation:

Here are the points and a graph showing the dilation in purple

Answer:

The answers are A, B and C.

Step-by-step explanation:

To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57

Next Divide 21 on both sides. -57/21 is -36

You should have -3k > -57

Divide -3 on both sides. -57/-3 is 12

You should end up with k > 12

And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

Hope This Helps! ^^

Answer:

22in²

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Circumference = 25 (1/7)

As we know,

Circumference of a circle = 2πr

By solving this we get

Radius (r) = 4in

Now. we can calculate the area by using following formula,

Area  = πr²

By putting the value, we get

Area = (22/7) × 4²

=  22/7 × 16

= 352÷16

Area = 22in²

Answer:

Step-by-step explanation:

Refer to attached picture.

All given dimensions are given on the picture (not to scale).

Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:

It has 9 faces and the total surface area is:

Answer: you have to divide each side by 8, not 4. If you divide by 4, you get 2x = 1

The correct answer would be 1/2

Answer: About 3 hours and 5 minutes to paint the room together.

Step-by-step explanation:

Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.

Room/Hour

1/5 ± 1/8 =8/40  

8/40+5/40=13/40

How long to paint the room?

13/40 x 1= 40/13

40÷13=3.0777

So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

Answer:

The derivative of the function is:

[tex]f'(x)=1-\frac{1}{x^{2}}[/tex]

Step-by-step explanation:

The first principle is given by:

[tex]f'(x)=\frac{dy}{dx}=lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}[/tex]

The function here is:

[tex]f(x)=x+\frac{1}{x}[/tex]

Now, using the first principle we have:

[tex]f'(x)=lim_{h\rightarrow 0}\frac{(x+h)+\frac{1}{(x+h)}-x-\frac{1}{x}}{h}[/tex]  

[tex]=lim_{h\rightarrow 0}\frac{h+\frac{1}{(x+h)}-\frac{1}{x}}{h}[/tex]    

[tex]=lim_{h\rightarrow 0}\frac{h-\frac{h}{x(x+h)}}{h}[/tex]    

[tex]=lim_{h\rightarrow 0}\frac{h(1-\frac{1}{x(x+h)})}{h}[/tex]

[tex]=lim_{h\rightarrow 0}1-\frac{1}{x(x+h)}[/tex]

[tex]=1-\frac{1}{x^{2}}[/tex]

Therefore, the derivative of the function is:

[tex]f'(x)=1-\frac{1}{x^{2}}[/tex]

I hope it helps you!

Answer:

d

Step-by-step explanation:

not a bc it has to be negative

not c bc its has to be negative

not b bc the slope is -1/2

IT'S D

Answer:

D

Step-by-step explanation:

from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.

Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.

we must then find the show of the line.

let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

so, let's label (0,3) as point 1 and (6,0) as point two. then,

x1 = 0

y1= 3

and

x2= 6

y2=0

Now we just plug in and simplify.

[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]

we now have our slope and y intercept, so we can plug them into our equation

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

where m is the slope and b is the y intercept.

our equation is thus

[tex]y = - \frac{1}{2} x + 3[/tex]

so, the answer is D

Answer:

-2

Step-by-step explanation:

If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

*correct me if I'm wrong, or If I didn't fully understand your question, because I am a little confused with how much homework Phil has finished.

Answer:

x=6

Step-by-step explanation:

x+54+5x=90

6x+54=90

6x=36

x=6

Answer:

x=6

Step-by-step explanation:

So, lets go over what we know.

Angle 5x and angle x+54 make up 90 degrees.

We know its 90 degrees since there is a square like symbol on the side of the line.

To sovle for x, we must add the two angles together. This will make them equivelent to 90 degrees.

So:

5x+x+54=90

=

6x+54

Now that we combined our two angles, we can solve it like a normal equation:

6x+54=90

subtract 54 from both sides to get 6x alone:

6x=36

Now divide both sides by 6 so x is alone:

x=6

So now we know that x=6.

If you wan to check your answer, just look at the orginal graph, plug in 8 for x, and see if the two angles add up to 90:

Angle 5x:

5*6

=

30

Angle x+54

6+54

=

60

Add the two angles together:

30+60

=

90

So we have checked and the answer is still correct!

Hope this helps! :D

Answer:

4L-12

Step-by-step explanation:

let's assume the length = L

then the width of the rectangle is L - 6

perimeter = 2× (a+b)

where "a" and "b" are the length and the width of the rectangle.

so perimeter = 2× (L + L - 6)

2 × ( 2L - 6)

4L - 12

Answer:16

Step-by-step explanation:

Answer: C(x) = 13x +95​

Step-by-step explanation:

Here's the remainder of the question:

If C(x) represents the total cost and x represents the number of people attending the banquet, which equation shows the total cost? A C(x)=95x – 13 B C(x)=13x – 95 C C(x)=95x +13 D C(x)=13x +95​

Based on the information given in the question, the total cost will be:

= 95 + 13(x)

= 95 + 13x

Therefore, the correct answer will be C(x)=13x +95​

Answer:

False

8 rows of seats are needed to fit all students

Step-by-step explanation:

Total students at the theater = 56

Number of seats per row = 7

Number of rows = 7

Total seats in the theater = Number of seats per row * Number of rows

= 7 * 7

= 49 seats

Rows of seats needed to fit all of the students is not 7 because the students are more than the number of seats in the theater.

Therefore,

8 rows of seats are needed to fit all students

Total seats in the theater = Number of seats per row * Number of rows

= 7 * 8

= 56 seats

If you knew the value of a, you would solve it completely.

Answer:

192 ft²

Step-by-step explanation:

Area of rectangular backyard = 1248 ft²

Width of backyard = 52 ft

Length = x

Area of rectangular backyard = Length * width

1248 = x * 52

x = 1248 / 52

x = 24 feets

Hence, x = height of triangular garden

Area of triangle = 1/2 base * height

Area = 1/2 * 16 * 24

Area = 192 ft²

Answer:

1/4

Step-by-step explanation:

Possible outcomes from rolling the cube that satisfy the "greater than 3" criterion are {4, 5, 6}  out of a total of six possibilities {1, 2, 3, 4, 5, 6}.  Thus, the probability of rolling a number greater than 3 is 3/6, or 1/2.

Probability of flipping heads is 1/2.

These are entirely independent events.  Thus, the joint probability is (1/2)(1/2), or 1/4.
