Answer:

There is one possible solution

Step-by-step explanation:

Here, we want to get the number of solutions

We can proceed to solve the equation

we have two y values so we can directly equate the x parts

-2x - 4 = 3x + 3

3x + 2x = -3-4

5x = -7

x = -7/5

To get y, we substitute

We can only get one value of y too

So we have a point (x,y) as the solution to the system of equations

Simplify the radical completely.

Answer:

Step-by-step explanation:

But basically, one by one you try moving the terms out of the radical.

75 is also 25 * 3 and since 25 has a perfect square root of 5 that goes out and 3 stays inside the radical.

x^3 is also x^2 * x and since x^2 has a perfect square root which is just x that goes outside while the remaining x stays inside.

y^9 is also y^8 * y and since we move variables out the radical in twos y^ goes outside the radical and y stays inside alone.

Finally, z is just z it can't be taken out so it stays inside the radical.

Hope that helps!

Given: ΔABC; a= 10; b = 4, and c = 11. Find the measurement of ∠B to the nearest tenth of a degree.

AleksAgata [21]

Use the Cosine Rule to find this

cos <B = [b^2 - a^2 - c^2] / -2ac

= [ 4^2 - 10^2 - 11^2] / -2*10*11

= 0.93182

so m < B = 21.3 degrees to nearest tenth. Answer

An interior designer is buying fabric to cover throw pillows for a master bedroom. She needs material to cover 6 pillows—3 recta

kherson [118]

Answer:

a. 552 square inches
b. 835.7 square inches
c. 1256.6 square inches
d. 4584 square inches
e. 432 cubic inches
f. 1847.3 cubic inches
g. 4188.8 cubic inches
h. 9179.3 cubic inches

Step-by-step explanation:

a-c. The area formulas for these figures are ...

rectangular prism: A = 2(lw +h(l+w))

cylinder: A = 2πr(r +h)

sphere: A = 4πr^2

d. The total will be the sum of products: area of each pillow times the number of that type

e-g. The volume formulas for these figures are ...

rectangular prism: V = lwh

cylinder: V = πr^2h

sphere: V = (4π/3)r^3

h. As with area, the total volume is the sum of products: volume of each pillow times the number of that type.
