What is the y-intercept of the line perpendicular to the line y = 3/4x + 3 that includes the point (-3, -3)
kipiarov [429]
A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4

The final equation is y= -4/3x + 21/4
The y intercept is (21/4).

Paula, the local baker, usually makes 15 loaves of bread and 10 cakes per day, but today she made 25 loaves of bread and 12 cake
frozen [14]

Answer:

Step-by-step explanation:

The percent increase formula is

%increase=\frac{new-original}{original}*100%

For the bread, our percent increase looks like this:

\frac{25-15}{15}*100

which gives us a percent increase of 66.7%

For the cakes, our percent increase looks like this:

\frac{12-10}{10}*100

which gives us a percent increase of 20%

a ladder is leaning against a wall. The ladder reaches 6 ft high on the wall and the base from the ladder is 2 ft from the wall
Katyanochek1 [597]
Ok the ladder and the ground will make a right triangle/right angle. This is because the ground is flat, the wall is straight and only the ladder is leaning/slanted. I hope this helps.

X – 2y = 1<br> 2x + 3y = -12
lions [1.4K]

Answer:

x= -3

y= -2

From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.
