Answer:

Bro this is sooooo true I hate when this would happen like I spent the whole day looking at the screen just so it can say "oh your question has been deleted" Like why do you have to do this too me *sigh*

We need to determine the equation of both lines first.

Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.

Line 1:

[tex]y = -2x + 3\\\\2x + y = 3[/tex]

Line 2:

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

Final answer:

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

m= 3/8

Step-by-step explanation:

Answer:

x= -2 y= -1

Step-by-step explanation:

stack the 2 equations on top of each other and add them together

the 2x and -2x cancel out and you are left with -9y=9

this gives you y= -1

you plug the y value into one of the equations:

2x - (-1) = -3

2x+1 = -3

2x= -4

x= -2

Answer:

45

Step-by-step explanation:

you can see that the time increases by 10.

ex: 5+10=15, 15+10=25.

So, 35 + 10 = 45

Answer:

Week 1: 14

Week 2: 18

Week 3: 2

Week 4: 9

Week 5: 23

Week 6: 6

Step-by-step explanation:

The question is asking for the percentage of absences each week given the percentage of attendance. We can calculate [tex]100\%-Attendance[/tex] (attendance is in percentage form) to find the percentage of people that were absent during each get-together:

Week 1: [tex]100\%-86\%=14\%\\[/tex]

Week 2: [tex]100\%-82\%=18\%[/tex]

Week 3: [tex]100\%-98\%=2\%[/tex]

Week 4: [tex]100\%-91\% = 9\%[/tex]

Week 5: [tex]100\%-77\% = 23\%[/tex]

Week 6: [tex]100\%-94\% = 6\%[/tex]

Hope this helps :)

Answer:

1/-4 Rise over run. So 1 would be your rise then the 4 is negative you would fall down 4.

Step-by-step explanation:

Well you would have to do the equation y2-y1 over x2-x1. You go from having two points to having it in sloe-intercept form becuase of your equation y2-y1 over x2-x1.

Step-by-step explanation:

$21

Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x

If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21

Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21

Answer:

8 x - 1

Step-by-step explanation:

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

Answer:

8x-1

Step-by-step explanation:

3x+5x=8x

8x-1

You add up the numbers that have the same variables, then add the extra numbers to numbers you solved.

Answer:

235or 236

Step-by-step explanation:

A cone has a radius of 5 cm

a height of 9 cm

Volume of cone =1/3πr^2h

=1/3×3.14×5×5×9

= 3.14×25×3

=3.14×75

=235.5

=235or 236 is the answer

Answer: 135.606 m

Step-by-step explanation:

Try using the law of cosine because if you draw the picture of the triangle out then you see it’s a SAS triangle

so in this case:

C squared equals 320 squared plus 300 squared minus 2 times 320 times 300 times cosine 25

Step-by-step explanation:

Mark brainlest please

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Responda:

C) 21%

Explicação passo a passo:

Dado que:

Dado 1: rotulado de 1 - 6

Dado 2: rotulado de 1 - 8

Espaço amostral :

8 * 6 = 48

Probabilidade = resultado necessário / resultados possíveis totais

Resultado necessário = soma maior que 10 = 10

Resultados totais possíveis = 48

P (soma> 10) = 10/48

P (soma> 10) = 0,208333

20,8333 * 100%

= 20,833%

= 21%

Answer:

12. 64

Step-by-step explanation:

total = 10.99 + (10.99*.15)

total = 10.99 *1.15

Answer:

[tex]y=40x+20[/tex]

Step-by-step explanation:

Answer:

4 (3 y + 2 x)^2

Step-by-step explanation:

Factor the following:

36 y^2 + 48 x y + 16 x^2

Hint: | Factor out the greatest common divisor of the coefficients of 36 y^2 + 48 x y + 16 x^2.

Factor 4 out of 36 y^2 + 48 x y + 16 x^2:

4 (9 y^2 + 12 x y + 4 x^2)

Hint: | Factor by grouping.

The coefficient of x^2 is 4 and the coefficient of y^2 is 9. The product of 4 and 9 is 36. The factors of 36 which sum to 12 are 6 and 6. So 9 y^2 + 12 x y + 4 x^2 = 4 x^2 + 6 x y + 6 x y + 9 y^2 = 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 2 x (3 y + 2 x) + 3 y (3 y + 2 x)

Hint: | Factor common terms from 2 x (3 y + 2 x) + 3 y (3 y + 2 x).

Factor 3 y + 2 x from 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 (3 y + 2 x) (3 y + 2 x)

Hint: | Combine products of like terms.

(3 y + 2 x) (3 y + 2 x) = (3 y + 2 x)^2:

Answer: 4 (3 y + 2 x)^2

Answer:

Step-by-step explanation:

given

first term(a)=4

last term (l)=(5n-1)

now

[tex]S_{n}[/tex]=[tex]\frac{n}{2}[/tex](a+l)

[tex]\frac{n(3+5n)}{2}[/tex]=[tex]\frac{n}{2}[/tex](a+l)

[tex]\frac{n(3+5n)}{2}[/tex]=[tex]\frac{n}{2}[/tex](4+5n-1)

[tex]\frac{n(3+5n)}{2}[/tex]=[tex]\frac{n}{2}[/tex](5n+3)

[tex]\frac{n(3+5n)}{2}[/tex]=[tex]\frac{n(3+5n)}{2}[/tex] true
