Answer:  x = 3

<u>Step-by-step explanation:</u>

5x - y = 8

It is given that y = 7, so substitute "y" with "7" into the equation:

5x - (7) = 8        <em>substituted y with 7</em>

5x        = 15       <em>added 7 to both sides</em>

 x         = 3        <em>divided both sides by 5</em>


When y = 7, then x = 3   ⇒   the coordinate is (3, 7)

Answer:

x = 3

Step-by-step explanation:

To find the x-coordinate, substitute y = 8 into the equation abd solve for x

5x - 7 = 8 ( add 7 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Thus (3, 7) is a solution to the equation

Eliminate B and C because the solid lines means there is a equal sign
between A and D, the line with the intercept of 3/2 has the area underneath shaded, so the sign should be < than, the line with the intercept of 1/2 has the area above it shaded, so the sign should be >. 
A satisfies both conditions, so A is the answer

Hiya please leave formulas x
Mekhanik [1.2K]

Answer:

angle c = 107°

angle b = 107°

angle a = 73°

Step-by-step explanation:

Given:

Two line XY and WZ intersect each other and make four angle [a, b, c, d]

Given that Angle d = 73°

Find:

angle a

angle b

angle c

Computation:

We know that angle c and angle d situated on same line XY

So,

angle c + angle d = 180°

angle c + 73° = 180°

angle c = 107°

We know that angle b and angle d situated on same line WZ

So,

angle b + angle d = 180°

angle b + 73° = 180°

angle b = 107°

angle a and angle d are vertical opposite angle

So,

angle a = angle d

angle a = 73°

What are the first 4 terms in the multiplication pattern given by the formula 2×4n
Stella [2.4K]

Answer:

8, 16, 24, 32

Step-by-step explanation:

To find the first 4 terms, substitute n = 1, 2, 3, 4 into the formula

n = 1 : 2 × (4 × 1) = 2 × 4 = 8

n = 2 : 2 × (4 × 2) = 2 × 8 = 16

n = 3 : 2 × (4 × 3) = 2 × 12 = 24

n = 4 : 2 × (4 × 4) = 2 × 16 = 32

How do you figure this out?
algol [13]

Let the red cat be represented by x.

Let the yellow cat be represented by y.

Let the white cat be represented by z.

Which means :

\tt (1) \:  \frac{4}{5} (20x - 5)

\tt =  \frac{4}{5}  \times 20x -  \frac {4 }{5}  \times 5

\tt=  \frac{80x}{5}  -  \frac{20}{5}

\tt = 16x - 14

Thus, the first statement is correct.

\tt(2)  \: \frac{3}{5} ( \frac{1}{3} z - 10)

\tt =  \frac{3}{5} \times  \frac{1}{3}  z -  \frac{3}{5}   \times 10

\tt =  \frac{3}{15} z-  \frac{30}{5}

\tt =  \frac{1}{5} z - 6

Thus, the second statement is a lie.

\tt(3) \:  \frac{1}{9} ( - 9y - 27x)

\tt=  \frac{1}{9}  \times  - 9y  -  \frac{1}{9}  \times 27x

\tt =  \frac{ - 9}{ \:  \: 9} y -  \frac{27}{9} x

\tt =  (- y) - 3x

Thus, the third statement is correct.

Therefore, <u>the second one is a lie</u>.
