Find the solution of the system of equations.

Mathematics
1 answer:
Alexandra [31]2 years ago
5 0

Answer:

x = -3

y = 9

Step-by-step explanation:

Add two equations up

4x + 5y - 9x - 5y = 33 - 18 add or subtract like terms

-5x = 15 divide both sides by -5

x = -3 we can use this information to find the value of y

4x + 5y = 33 replace x with -3

4 * (-3) + 5y = 33

-12 + 5y = 33 add 12 to both sides

5y = 45 divide both sides by 5

y = 9

Explain why the initial value of any function of the form<br> f(x) = a(br) is equal to a.
Natasha_Volkova [10]

Answer:When you substitute 0 for the exponent x, the expression simplifies to a times 1, which is just a. This is because any number to the 0 power equals 1. Since the initial value is the value of the function for an input of 0, the initial value for any function of this form will always be the value of a

what is a more accurate method for approximating the volume of the spherical slab other than using just cylindrical slabs.
jasenka [17]

A more accurate method for approximating the volume of the spherical slab other than using just cylindrical slabs is the; use the cross sections of the actual sphere, and to not use the cylindrical slabs.

<h3>What is a Cylinder?</h3>

A Cylinder is a surface created by projecting a closed two-dimensional curve along an axis intersecting the plane of the curve.

Sphere

This is a regular three-dimensional object in which every cross-section is a circle; the figure described by the revolution of a circle about it's diameter.

Therefore, the use of cross sections of the actual sphere is a more accurate method for approximating the volume of the spherical slab.

When estimating a square root, how do you find the numerator in your fraction of your estimation?
Tasya [4]

Answer:

To get your numerator you subtract the first two numbers, 63 - 49 = 14. That leaves you with 14 over 15 or . 93. Since the square root of 63 is higher than 7 but less than 8 your whole number is 7
