y = -3.x + 4. y = 4x – 10
Enter your math answer
Answer:
y= -2 and x= 2.
Step-by-step explanation:
(y=-3x+4)4
(y=4x-10)3
make the x's cancel out.
you get 7y=-14.
y=-2.
-2=-3x+4
x=2
what is -4(x+3)=16-4x
Answer:
There is no solution
Step-by-step explanation:
-4(x+3)=16-4x
expand
−4x−12=16−4x
cancel out
−12=16
because −12=16 is false there is no solution.

4. A square pyramid has
measures 8 inches on each side. The height
of the pyramid is 11.5 inches. Determine the
volume of the pyramid.
volume:
Answer:
[tex]V = 245\frac{1}{3} in^{2}[/tex]
Step-by-step explanation:
The volume of a pyramid is equal to the area of the base times height divded by three so
[tex]V = \frac{A_{base} h }{3} \\V = \frac{(8^{2})(11.5) }{3} \\V = \frac{736}{3} \\V = 245\frac{1}{3} in^{2}[/tex]
Answer:
245 1/3
Step-by-step explanation:
Help me plzzzz, thanks If you do

THANK YOU.
Sample Response: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).
Which did you include in your response? Check all that apply.
Negate the y-coordinate.
Negate the x-coordinate.
Get the point (–5, –2).

the figure below is made of two triangular prisms. what is the volume of the figure
Answer:
896 cubic inches
Step-by-step explanation:
V (Δ prism) = 1/2 · height · base · length
V (top prism) = 1/2(6)(12)(14)
V (top prism) = 504 in³
V (bottom prism) = 1/2(7)(8)(14)
V (bottom prism) = 392 in³
504 + 392 = 896

PLEASE HELP if 5 more than 3 times a number is -4, what is the number?
Answer:
x = -3
hope it's helpful ❤❤❤
THANK YOU.
Hey there!
The answer to your question is "n = -3"
First, we can start by writing the equation as it says. "3 times a number" represents a number times 3, or "3n"
3n
Next, "5 more" represents addition, so "+ 5"
3n + 5
Finally, "is -4" means it is equal to -4, so "= -4"
3n + 5 = -4
Now that we have our equation, we can solve:
3n + 5 = -4
First, we subtract "5" from both sides of the equal sign:
3n = -9
Lastly, we divide both sides by "3".
n = -3
Have a terrificly amazing day!
