an = ???
-please help

Answer:

[4]x+[8]=[1×]+2

Step-by-step explanation:

x will be negative now that the more x you have the higher your number will have to be.

The requried, x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution as x = -3.5.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
One possible solution is,

[1]x + [2] = [3]x + [9]

To see that this equation has a negative solution, we can rearrange it to get:

x + 2 = 3x + 9

x - 3x = 9 - 2
-2x = 7
x = -3.5

Since x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution.

Answer:

x = -7

Step-by-step explanation:

These angles are supplementary because they're same side interior angles. Supplementary means the 2 angles add up to 180

Equation:

x + 67 + x + 127 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -14/2

x = -7

Hi how u doin ?

[tex](x + 67) + (x + 127) = 180[/tex]

[tex]x + x + 67 + 127 = 180[/tex]

[tex]2x + 194 = 180[/tex]

Subtract both sides 194

[tex]2x + 194 - 194 = 180 - 194[/tex]

[tex]2x = - 14[/tex]

Divide both sides by 2

[tex] \frac{2x}{2} = \frac{ - 14}{2} \\ [/tex]

[tex]x = - 7[/tex]

There it is the God dm x lol ...

Answer:

s ≤ 15

Step-by-step explanation:

1/15(60 - s) ≥ 3

4 x 15 - s/15 x 15 ≥ 3 x 15

60 - s - 60 ≥ 45 - 60

-s/-1 ≥ -15/-1

Answer:

Distance = 6.7 units

Step-by-step explanation:

Distance formula: [tex]d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

[tex]d = \sqrt{(8.5-8.5)^{2}+(2.2-8.9)^{2}} = \sqrt{(-6.7)^{2}} = 6.7[/tex]

Note that distance is always positive

Answer:

2 sides are [tex]\frac{33}{13}[/tex] or 2.5

2 sides are [tex]\frac{47}{13}[/tex] or 3.6

Step-by-step explanation:

There must be 2   2x+3s  and 2   3x+2s

The perimeter is the sum of the sides (it has 4 sides)

2(2x+3) + 2(3x+2) = 4(4x-5)

distributive property

2*2x + 2*3

4x+6

other one

2*3x + 2*2

6x+4

perimeter

4*4x + 4*-5

16x-20

together...

(4x+6) + (6x+4) = 16x-20

add like terms

10x+10 = 16x-20

add 20 to both sides

10x+30 = 16x

subtract 10x from both sides

30 = 26x

divide by 26 on both sides

[tex]\frac{30}{26} = x[/tex]

simplify

[tex]\frac{15}{13}[/tex]

Substitute the x value

2 of the sides are 2x+3

so

[tex]2(\frac{15}{13} ) + 3[/tex]

[tex]\frac{30}{13} + \frac{3}{1}[/tex]

[tex]\frac{33}{13}[/tex]

or 2.5

other sides

[tex]3(\frac{15}{13} ) + 2[/tex]

[tex]\frac{45}{13} + \frac{2}{1}[/tex]

[tex]\frac{47}{13}[/tex] or 3.6

That's all I can say for now! Hope this helps and a thank won't hurt! :)

Answer:

A - 142

B - 38

C - 38

D - 142

E - 142

F - 38

G - 38

H - 142

Step-by-step explanation:

It's been a while since I've done these so please don't judge

Answer:

Well this is pretty simple

Parralel lines cut by a transversal.

So we have one measurement of 142 which is a

A and B are supplementary (When added up you get 180 degrees)

So basically to find that you can do this

180-142=38

So B is 38

We can now use vertical angles.

A and D are vertical and vertical angles are congruent (equal)

d is 142

B and c are congruent

B is 38 so C is also 38

Now We find EGHF

Techcinally we can just do what i would do which is draw and x between the vertical angles

So if drawn an ”X” you can see the sam exact pattern as for ABCD

Which in this case E is 142

H is 142

F is 38

G is 38

If done the hard way you can use altenrate/same side (interior exterior)/ Corresponing angles.

So Here’s what you need to know

Alternate interior and exterior are equal

Correspnding angles are equal

Same side are supplementary

Thats all you need to know.

Interior is basically BD and EG

Exterior is AC and FH

Correspnding are basically same sides but one is ont he inside and one is on the outside

Ex:

A and E

B and F

C and G

D and H

Same side is EXACLTY what is sounds like, the same side but everything has to be either interior or exterior

(Interior) B and E

(Interior) D and G

(Exterior) A and F

(Exteiror) C and H

Final answers:

A- 142

B- 38

C- 38

D- 142

E- 142

F- 38

G- 38

H- 142

Answer:

-5.230,0000

Step-by-step explanation:

Your number in decimal form is -52,300,000 . The negative sign remains unchanged. To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, -52,300,000 becomes -5.230,0000

Hotdog tatay mo sabog pakyou

Answer:

3 ( 917 ) = 3 ( 900 ) + 3 ( 10 ) + 3 ( 7 )

5 ( 209 ) = 5 ( 200 ) + 5 ( 0 ) + 5 ( 9 )

6 ( 347 ) = 6 ( 300 ) + 6 ( 40 ) + 6 ( 7 )

9 ( 821 ) = 9 ( 800 ) + 9 ( 20 ) + 9 ( 1 )

11 ( 142 ) = 11 ( 100 ) + 11 ( 40 ) + 11 ( 2 )

Step-by-step explanation:

Answer:

Hint(look at the first number in each part and math it with the first number in each answer.) For example, 3(937), the distributive property for that one would be 3(900) + 3(30) + 3(7). Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.

Answer:

C

Step-by-step explanation:

Answer:

7x + 2y = 1

Step-by-step explanation:

1. Find the slope of the line.

(y2-y1)/(x2-x1) ---->  (11 - (-3))/((-3) -1) ----> (11+3)/ (-3 -1) ----> 14/-4

*lets simplify into (7/-2)*

2. Write into slope intercept form.

y=mx+b (m is the slope) (b is the y intercept)

y = (7/-2)x + b

We now need to find the value of b, this can be done by plugging in values of x and y, and using algebra to solve.

11 = (7/-2)(-3) + b

11 = 10.5 + b

b = 0.5 or 1/2

slope intercept form y = (7/-2)x + 1/2

Now we convert to standard form: ax+by=c

*In this form we our a term cannot be a fraction nor can it be negative*

1. Get x and y on the same side, and since our x term is negative right now, we can make it positive by adding it on both sides.

(7/2)x + y = 1/2

2. We now want to get rid of the fraction in term a, so we multiply the entire function by two, so the denominator cancels out.

2(7/2)x + 2y = 2(1/2)

Simplify and you get

7x + 2y = 1

Answer:

1. = station A

because 15 gallons = 0.75 discount at B but station A has a 1.50 discount at 15 gallons

Step-by-step explanation:

2. for satation B you have to read the graph

but for station A it is unclear on the graph

a way to work it out is that you know that 10= 1.00 so 12 = 1.2

( divide 12 by 10 )

station B = discount for 12 gallons = 0.6

but Station A = discount for 12 gallons = 1.2

the difference is

1.2 - 0.6 = 0.6 discount
