Can anyone solve this for me

Mathematics

Answer:

(-2, -4.5)

Step-by-step explanation:

We can solve this equation with substitution.

x=2y+7

3x-2y=3

We can "substitute" 2y+7 for x into the second equation:

3(2y+7)-2y=3

Distribute the 3

6y+21-2y=3

Add like terms

4y+21=3

Subtract 21 from both sides

4y=-18

Divide both sides by 4 to isolate y

y=-4.5

Plug -4.5 back in for y:

x=2(-4.5)+7

x=-9+7

x=-2

(x,y)=(-2,-4.5)

Find the volume in cubic millimeters.
forsale [732]

Answer:

Option B is correct.

volume in cubic millimeters is, 8000 cubic mm

Step-by-step explanation:

Volume of a cube is found by multiplying the length of any edge by itself twice.

It is given by:

V = a^3 cubic units,......[1] where V represents the volume of a cube and a represents the side of a length.

From the given figure;

Length of a side(a) = 2 cm

Use conversion, to convert cm into mm;

1 cm = 10 mm

then;

2cm  =20 mm

⇒length of a side(a) = 20 mm

Substitute the value of a = 20 mm in [1];

V = (20)^3 cubic mm

Simplify:

V = 8000 mm^3

Therefore, the volume in cubic millimeters is, 8000 cubic mm

1. Solve for the x and y intercepts:
aleksandrvk [35]
To find the x-intercept, you simply make y equal to 0 and solve the equation for x. To find the y-intercept, you make x equal to 0 and solve for y. So, for number 1, the answer is D because when you set it to y equals 0, you get x=3 and when you set it to x equals 0, you get 4. 
Number 2 we would do the same thing and get D as well.
Hope this helps!

What is the volume of the prism?
jeka57 [31]
The volume prism refers to the number of cubic units that will exactly fill the figure. The volume of a rectangular prism can be found or calculate by using the formula V=Bh, where B represents to the area of the base or in other words the length and width of the rectangle.

In this exercise is given that the measurements of a prism are 5/2ft, 3/2ft, and 7/2ft; and it is asked to find its volume. In order to find the volume of the prism, you should substitute the given values into the previous mention formula.

V=Bh
V=(5/2 ft)(7/2 ft)(3/2 ft)
V=(35/4 ft²)(3/2 ft)
V=105/8ft³  or 13 \frac{1}{8}ft³

The volume of the rectangular prism is 13 \frac{1}{8}ft³.
