As Wikipedia says, "In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x^2 − 2xy + c is an algebraic expression."
7 + x is the algebraic expression you'd want.

Solve the system by substitution. Then check the solution again in each equation.
y =-2x - 6
y = x + 15
y - -2x - 6 (1)
y = x+15 (2)
From (2) we get x = y-15
We put that in (1) and we get -2(y-15)-6 = y
-2y+30-6 = y
-2y+24=y
-2y+24-y=0
-3y+24 = 0 ==> -3y = -24 ==> y = 8
We put that value in (2) and we get x = 8-15 = -7
Now in order to verify this, we replace the variables and see if (1) = (2)
y = -2x - 6 ==> (-2 * -7) - 6 = 14-6 = 8 (1')
y = x + 15 = -7 + 15 = 8 (2')
(1') = (2') ==> the solution is x = -7 and y = 8
Answer:
x=−2y=2
Step-by-step explanation:
Take the value of x from the first equation:x=2−2y (1)and substitute for x into the second:y=2(2−2y)+6
solve for y ;y=4−4y+6y=105=2
Substitute back into
(1) and find :x=2−4=−2

i need help with the triangle. i would rather anyone tell me step by step so i can understand how to do it next time, thank you.
Answer:
Volume of triangular prism = 126
Volume of composite figure = 462
Step-by-step explanation:
The volume of a triangular prism is base area x height
Here the base of the triangular prism has sides 7(the vertical side) and 6(the horizontal side). The are of this base = area of the triangle = 1/2 * 7 * 6 = 21
(Area of a triangle is 1/2 x b x h where b is base and h is height)
The volume of the prism is simply this area x width = 21 x 6 = 126
To get the composite figure volume add the volume of the rectangular prism so we get 126 + 336 = 462
Answer:
126 cm³
Step-by-step explanation:
The volume of the triangular prism can be calculated using the formula below:
Volume of prism= base area ×height
Area of base
= area of triangle
= ½ ×base ×height
= ½(6)(7)
= 21 cm²
The height of the triangle is the same as the length of the 7cm side of the rectangle.
In this figure, the height of the prism is 6 cm.
Volume of triangular prism
= 21(6)
= 126 cm³
_______
Area of composite figure
= area of rectangular prism +area of triangular prism
= 336 +126
= 462 cm³
Please help its very easy

Step-by-step explanation:
If they start at 4 on the y-axis, they can go down to 1 or go up to 7. Then we just add the -3 to the x axis.
Answer:
(-3,7) and (-3,1)
Step-by-step explanation:
You would move the point up or down one (this is because you are moving on the y-axis) which would only change y leaving x alone as -3. This means you would either subtract 3 or add 3 to 4 which gives you 1 or 7.

A valley in California has an elevation of feet below sea level. A valley in Arizona has an elevation lower than the one in California. Which of these could be the elevation of the valley in Arizona? 3 feet 0 feet -5 feet -9 feet
The valley in California has an elevation of feet "below sea level".
Below sea level means below 0 feet, so it'd have -5 feet
The one in Arizona would be lower than it, so the elevation will definitely be -9 feet

What is -3x less than 12
Answer:
[tex]x < 4[/tex]
Step-by-step explanation:
In order to isolate the variable in this linear inequality, we need to get rid of the coefficient that multiplies it.
This can be accomplished if both sides are divided by 3.
3x /3 = 0x
12 /3 = 4
So the asnwer is x = 4 (don't forget the less than sign)
