Answer:

(-3,5)

Step-by-step explanation:

4x + 3y = 3

x − 3y = −18

Solve by addition/Elimination

x = -3

y = 5

So,

The solution of the system is (-3,5).

Answer: x = 4 , y = 6

Step-by-step explanation:

4 x = 3 y − 2 , 18 = 3 x + y

Solve for y

in the second equation.

Tap for more steps...

4 x = 3 y − 2 y = 18 − 3 x

Replace all occurrences of

y in 4 x = 3 y − 2

with

18 − 3 x . 4 x = 3 ( 18 − 3 x ) − 2 y = 18 − 3 x

Simplify

3 ( 18 − 3 x ) − 2

Tap for more steps...

4 x = − 9 x+ 52 y = 18 − 3 x

Move all terms in

4 x = − 9 x + 52

to the left side and simplify.

Tap for more steps...

13 x − 52 = 0 y = 18 − 3 x

Solve for x

in the first equation.

Tap for more steps...

x = 4 y = 18 − 3 x

Replace all occurrences of

x in y = 18 − 3 x

with 4 . x = 4 y = 18 − 3 ⋅ 4

Simplify

18− 3 ⋅ 4

Tap for more steps...

x = 4 y = 6

The solution to the system of equations can be represented as a point.

( 4 , 6 )

The result can be shown in multiple forms.

Point Form:

( 4 , 6 )

Equation Form:

x = 4 , y = 6

!*I NEED HELP AND QUICK*!

1)96/8=12
2)(95*6+5)/6 : (24+1)/3 = (95*6+5)/6 : 2*25/6 = 575/6 *6/50=575/50
=23/2=11 1/2
11 1/2

3) (11 1/2)*12 area of the one type of the wall, there are 2 such walls
(11 1/2)*12*2
(8 1/3)*12 area of the second type of the wall, there are 2 such walls
(8 1/3)*12 *2

Altogether area of the walls:
(11 1/2)*12*2 + (8 1/3)*12 *2=12*2(11 1/2 + 8 1/3)= =24(19+3/6+2/6)=24(19+5/6) = 456 +24*(5/6)= 456+20= 476

Line k has a slope of - 1/6. What is the slope of a line that is perpendicular to like k?

Lemur [1.5K]

The slope of a line and the perpendiular line that intercept will always have a product of -1

If the slope k=-1/6, the perperndicular line can be found by finding the product of the slope and -1

-1= (slope)(perpendicular line slope)
perpendicular line slope= slope(-1)
= -1/6(-1)
= 6

PlZ HELP !!!! if you can AWNSER either one if those please

Problem 1

The two angles 6x and 30 are vertical angles, so they are congruent or the same in measure.

6x = 30

x = 30/6

x = 5 is the answer

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

Problem 2

The two angles form a straight angle which is 180 degrees. We consider them a linear pair (since they are adjacent and supplementary).

So,

5x+(3x+12) = 180

8x+12 = 180

8x = 180-12

8x = 168

x = 168/8

x = 21 is the answer

NEED HELP ASAP PLEASE

If the unknown value is x, then x = $\frac{14}{4}$ × 6 = 21.

Explanation:

Since it is a double number line with a ratio, all the ratios of one number line to the other will remain equal for all the values along both the number lines. Assume the unknown value to be x.
The ratio of the number on the first number line to the corresponding number on the second number line is calculated to be; $\frac{7}{2}$ = $\frac{14}{4}$ = $\frac{x}{6}$ = $\frac{28}{8}$ = $\frac{35}{10}$ = 3.5. So $\frac{x}{6}$ = 3.5, x = 3.5 × 6 = 21.
We can also calculate x by the following method. As ratios are equal we can directly substitute the value to another ration. So $\frac{14}{4}$ = $\frac{x}{6}$ , x = $\frac{14}{4}$ × 6 = $\frac{84}{4}$ = 21.
