13. 3(x-6)-8=-2 (you have to plug in x-6 as x in the equation

3x-18-8=-2 (distribute 3)

3x-26=-2 (combine like terms)

3x=24 (subtract 26 to both sides)

x=8 (divide 3 to both sides)

14. -2(3(5y+5)=-4

-2(15y+5)=-4

-30y-10=-4

30y=6

y=1/5

15. (3x-5) +2x = 90

16. Let m be the number of minutes

0.75m+32 = 47

Using this equation you can find the number of minutes.

0.75m = 15 ( subtract 32 to both sides)

m= 20 (divide 0.75 to both sides)

Vera called 20 minutes beyond her allowed minutes.


Here I hope that this helped you out hon :)

In triangle ABC above, AD is perpendicular to CB. If the lengths of AD and CB were both increased by 50%, how would the area of
astra-53 [7]

Answer:

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, equilateral triangle, isosceles triangle.

The area of a triangle is given as:

A = (1/2) * b * h

where b = base of triangle, h = height of triangle , A = area

Let BC = base = x, and AD = height = y, hence:

A = (1/2) * x * y = 0.5xy

If the lengths of AD and CB were both increased by 50%, hence:

new AD = y + 0.5y = 1.5y, new CB = x + 0.5x = 1.5x

The new area= (1/2) * 1.5y * 1.5x = 1.125xy

Increased area / area = 1.125xy / 0.5xy = 2.25

If the lengths are increased by 50%, the area would also increase and the new area would be 2.25 times

Please help me!!!!!!!

Answer:

  y = -4x +2

Step-by-step explanation:

The equation you're writing is in slope-intercept form. The coefficient of x is the slope, which is the "rise"/"run" of the line.

Here, to get from the left point to the right point, you must go down 4 units (rise=-4) and 1 unit to the right (run=1). So, the slope is ...

  m = rise/run = -4/1 = -4

The constant in the equation is the y-intercept: the y-coordinate of the point where the line crosses the y-axis. That point is marked as (0, 2), so its y-coordinate is 2.

The equation for the line is ...

  y = -4x +2
