Answer:

x = -2

Step-by-step explanation:

Add 10 to both sides of the equation

x−10=−12

−10+10=−12+10

Simplify

Solution:

x= -2

Answer:

Both of them are correct.

Step-by-step explanation:

Both of them are correct.  

EQ. 1)  y = -2x + 3

EQ. 2)  6x + 3y = 9

Transform EQ. 2 into its slope-intercept form, y = mx + b:

6x + 3y = 9

6x - 6x + 3y = -6x + 9

3y = -6x + 9

3y/3 = (-6x + 9)/3

y = -2x + 3  (As you can see, Equation 2 is equivalent to Equation 1's).

Given that Equations 1 and 2 are equivalent, their lines will coincide on top of each other (as if they're the same line) once graphed.  

Therefore, the systems of linear equations will have infinitely many solutions.

Let's see why Charles and Destiny are both correct with their claims.  

If you plug in Charles' coordinates (3, -3) in both equations,

EQ. 1)  y = -2x + 3

-3 = -2(3) + 3

-3 = -6 + 3

-3 = -3  (True statement)

EQ. 2)  6x + 3y = 9

6(3) + 3(-3) = 9

18 - 9 = 9

9 = 9 (True statement)

Do the same thing for Destiny's coordinates: (-1, 5)

EQ. 1)  y = -2x + 3

5 = -2(-1) + 3

5 = 2 + 3

5 = 5 (True statement)

EQ. 2)  6x + 3y = 9

6(-1) + 3(5) = 9

-6 + 15 = 9

9 = 9  (True statement)

With these calculations, it shows that both of their coordinates are solutions to the given systems of linear equations.

Answer:

I am not sure but this is what I got

Step-by-step explanation:

1/3, 1/4, 2/5are the fractions. when we find the LCM= 60

the fractions become 20/60, 15/60 and 24/60

add all of them we get 59/60

total = 60/60

total -used part of cake = unused part of cake

60/60 - 59/60 = 1/60

hope it helps :) pls check if there are any mistakes

Answer:3.33%

easy

Step-by-step explanation:

A = true value = 60

B = estimated or measured value = 62

C = percent error

C = ( |A-B|/A ) * 100%

C = ( |60-62|/60 ) * 100%

C = (2/60)*100%

C = 0.0333*100%

C = 3.33%

Step-by-step explanation:

Use the Slope formula...

[tex]\frac{-3-5}{2-(-4)}[/tex]

[tex]\frac{-8}{6} = \frac{-4}{3}\\\frac{-4}{3} = m[/tex]

Plug the slope into the Point-Slope formula...

[tex]y -(5) = \frac{-4}{3}(x-(-4)) \\y+5=\frac{-4}{3}x +\frac{-16}{3}\\y=\frac{-4}{3}x +\frac{-1}{3}[/tex]

Answer:

Step-by-step explanation:

Please refer to the attachement. I defined the height (H), width (W), and length (L) and set:

H = 4m and W = (1/3)L. The total cost of 640 Rs/m^2 is divided by the rate cost of Rs 5/m^2 to give 128 m^2 that was plastered. The total area of the walls must be 128 m^2, so then calculate the total wall area: The walls for the length are 2*LH and for the width are 2*WH. Substituting, we have a total of 8*L + (4/3)L = 128 m^2. Solve for L to obtain L = 12m. W is 1/3L, or 4m. The room is (W,L,H) 4, 12, and 4 meters. The floor is W*L, or 48m^2. At Rs 250/m^2, the rug will cost Rs 12000. Ouch.

Then, solving:

[tex](x - 5)^2 = 18[/tex]

[tex]x^2 - 10x + 25 = 18[/tex]

[tex]x^2 - 10x + 7 = 0[/tex]

Which is a quadratic equation with [tex]a = 1, b = -10, c = 7[/tex]. Then:

Step-by-step explanation:

From the table

1 → - 2 ⇒ 1 - 3

2 → - 1 ⇒ 2 - 3

3 → 0 ⇒ 3 - 3

The rule is subtract 3 from the input to obtain output , then

4 → 4 - 3 = 1

n → n - 3 ← is the general rule for the table

Answer:

it will take the certain particle 15/4 (unit of time) to reach 30 km/hr

Input 30 as for y and solve the equation.

Step-by-step explanation:

Since y is kilometers per hour and the question is asking for how long it takes for a certain particle to reach 30 km/hr, you input 30 for y and solve for x.

-4x + y = 15

-4x + (30) = 15

subtract 30 from both sides

-4x = -15

divide -4 from both sides

x = 15/4

it will take the certain particle 15/4 (unit of time) to reach 30 km/hr
