6y-4=4y+2

2y=6, so y=3.

Plugging it in, you get that AC equals 4*3+2=14.

This is an isosceles triangle.

HELP PLEASE! whats the height and base??
ddd [48]

Answer: 7.5

Step-by-step explanation:

Area of the bottom left triangle = 4x3/2 = 6

Bottom right = 6x3/2 = 9

Top right = 3x4/2 = 6

Top left = 6x3/2 = 9

6+9+6+9 = 30

Each square unit is 4

So the answer should be 30/4 = 7.5

Hope this is correct

What is an equation of the line that passes through the point (8,-7)(8,−7) and is parallel to the line 5x+4y=165x+4y=16?
gizmo_the_mogwai [7]

Answer:

The equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 is  \mathbf{y=-\frac{5}{4}x+3}

Step-by-step explanation:

We need to write an equation of the line that passes through the point (8,-7) and is parallel to the line 5x+4y=16.

The equation will be of form y=mx+b where m is slope and b is y-intercept.

Finding slope of the line:

Since both the lines are parallel, and we know that parallel lines have same slope.

The slope of given line 5x+4y=16 can be found by writing in slope-intercept form y=mx+b

5x+4y=16\\4y=-5x+16\\y=-\frac{5}{4}x+16

Comparing with y=mx+b the slope m is: m=-\frac{5}{4}

So, the slope of required line is: m=-\frac{5}{4}

Now, finding y-intercept b

y-intercept can be found using slope m=-\frac{5}{4} and point (8,-7)

y=mx+b\\-7=-\frac{5}{4}(8)+b\\-7=-5(2)+b\\-7=-10+b\\b=-7+10\\b=3

So, we get y-intercept: b=3

Now, the equation of required line having slope m=-\frac{5}{4} and y-intercept b=3 is:

y=mx+b\\y=-\frac{5}{4}x+3

So, the equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 \mathbf{y=-\frac{5}{4}x+3}
