Graph the line with 3/4 slope<br> passing through the point (2,-2).

S_A_V [24]

Answer:

Step-by-step explanation

x1 = 2, y1 = -2 and m = 3/4

y - y1 = m(x - x1)

y - (-2) = 3/4(x - 2)

y + 2 = 3/4(x - 2)

Multiply each term by 4

4y + 8 = 3(x - 2)

4y + 8 = 3x - 6

4y = 3x - 6 - 8

4y = 3x - 14

5х + y = 16<br> х+ 6у = 38

Ainat [17]

Answer:

$(2,6)$

Step-by-step explanation:

Solve by substitution. Solve the second equation for x:

$x+6y=38\\\\x+6y-6y=38-6y\\\\x=38-6y$

Insert the value of x into the first equation:

$5(38-6y)+y=16$

Solve for y. Simplify multiplication using the distributive property:

$5(38)+5(-6y)+y=16\\\\190-30y+y=16\\\\190-29y=16$

Subtract 190 from both sides:

$190-190-29y=16-190\\\\-29y=-174$

Isolate the variable to find its value. Divide both sides by -29:

$\frac{-29y}{-29}=\frac{-174}{-29} \\\\y=6$

Now take the value of y and insert back into either equation to solve for x:

$5x+6=16$

Subtract 6 from both sides:

$5x+6-6=16-6\\\\5x=10$

Divide both sides by 5:

$\frac{5x}{5}=\frac{10}{5}\\\\ x=2$

Therefore, the solution to the system is $(2,6)$ .

The square pyramid shown below has a base with sides of 12 units. The vertical height of the pyramid is 15

KIM [24]

Answer:

<h3>s = 16.2 units</h3><h3></h3>

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = 12/2 = 6

b = 15

c = s

<u>plugin values into the formula:</u>

6² + 15² = s²

s = √(6² + 15²)

s = √261

s = 16.2 units
