Answer:

x = 59

y = 83

Step-by-step explanation:

First, you need to solve for y in order to solve for x. Using the Triangle Sum Theorem, you will find that y is 83 degrees.

Now, using the Vertical Angles Theorem, you can figure out the third angle of the triangle in which x is, 83.

Using the Triangle Sum Theorem again, you will find that x is 59.

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10

Veseljchak [2.6K]

Answer:

6 # plastic bricks
4 # wooden blocks

Step-by-step explanation:

Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...

10p +5(10-p) = 80

5p = 30 . . . . . . . . . subtract 50

p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix

4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.

A curve passes through the point ????0, 5???? and has the property that the slope of the curve at every point P is twice the y-c

Angelina_Jolie [31]

Answer: $y=2x^2$

Step-by-step explanation:

Given Curve passes through $\left ( 0,5\right )$

Also the slope of the curve at every point p is twice the Y-coordinate of p

Let the coordinate of p be $\left ( x,y\right )$

Therefore

$\frac{\mathrm{d} y}{\mathrm{d} x}=2y$

$\frac{dy}{y}=2dx$

Integrating both sides

$\int \frac{dy}{y}=\int 2dx$

$\ln y=2x+c$

Substituting values

$\ln 5=c$

$\ln \frac{y}{5}=2x$

$y=2x^2$

The equations of two lines are given. Determine if the lines are parallel, perpendicular, or neither.

andrey2020 [161]

Answer:

8x-7y=6

or, -7y=-8x+6

or, y=8x/7-6/7

so the slope is 8/7

8x-y=-8

or, -y=-8x-8

or, y=8x+8

So the slope is 8

Both has different slope and they don't satisfy the property of being perpendicular to each others, so they're neither parallel nor perpendicular.
