1. The linear equation y = 3x tells us that this line is going to be more vertical or horizontal? Explain.

More vertical.
y=x, where the slope is 1, is a line that forms a 45 degree angle with the positive part of the x axis. y=3x has a bigger slope, so it is going to rise 3 times faster than y=x so the line is more vertical
I hope that makes sense.

The linear equation y=3x tells you that it’s going more vertical

-1/4x – 2/3x = -6 + 28

Answer:

x= -24

Step-by-step explanation:

-1/4x-2/3x= -6+28

add -6 to 28 but since 6 is a negative its subtraction

-1/4x-2/3x=22

multiply all by 12

-3x-8x=264

add -3x to -8x

-11x=264

divide both sides by -11

x= -24

Can someone step by step explain the answer to me please and thank u

First

angle in front of c is 30°, so hypotenuse is equal to 2c

it's right triangle, so let's use Pythagorean theorem\

$(2c)^2=c^2+4^2\\4c^2=c^2+16\\3c^2=16\\\\c^2=\dfrac{16}{3} \\\\c=\dfrac{4}{\sqrt{3} } =\dfrac{4\sqrt{3} }{3 }$

Second

b - the base of the triangle, angles at the base are equal ⇒ cathets are equal

it's right triangle, so let's use Pythagorean theorem

$b^2=7^2+7^2\\b^2=49+49\\b=\sqrt{2\times49} =7\sqrt{2}$
