What is an algebraic expression ?
An expression built up from integer constants , variables and algebraic operations .
Let the number be : x
now , in the algebraic expression for 4 more then 3 times a number
First we need to make the number 3 time = 3x
then in that expression we need to add 4 , we get = 3x+ 4

How many moles contain 1.25x 10^15 molecules of glucose
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

How do i slove for x2 + 19 = 3
Answer:
x = ± 4i
Step-by-step explanation:
x^2 + 19 = 3
Subtract 19 from each side
x^2 +19-19 = 3-19
x^2 = -16
Take the square root of each side
sqrt(x^2) = sqrt(-16)
x = sqrt(-1*16)
x =sqrt(-1) * sqrt(16)
We know that the square root of -1 is the imaginary number i
x = ± 4i

Answer:
-6^2
Step-by-step explanation:
-6 x -6 = 36
Answer:
(−6)²
Step-by-step explanation:
(−6)⋅(−6)
This means the numbers are being multiplied.
A number is being multiplied by the same number. You can write an exponent for the number of times it's being multiplied by itself.
Example:
x = x¹
x·x = x²
x·x·x = x³
You are multiplying (−6) twice.
(−6)⋅(−6) = (−6)²

Answer:
It would double in size
Step-by-step explanation:
Judging as the circumference of a circle is dependent on the diameter, a circle whose diameter doubled in size would double.
An example would be a circle with the circumference of 20. It's radius would be 10 rather than 5. The circumference of the circle with a diameter of 10 would be roughly 31, while the circle with a diameter of 20 would have a circumference of roughly 62.

A triangle is 180 degrees.
You have to add 99 and 43 first.
99 + 43 = 142
You then subtract 142 from 180 to find the missing angle.
180 - 142 = 38

As indicated below, write the equations of the line passing through the point (2, 2) and perpendicular to the line whose equation is y = x.
Part 1: Point-Slope form of the linear equation
Part 2: Slope-intercept form of the linear equation
Part 3: The general form of the linear equation
Answer:
See answers below
Step-by-step explanation:
Equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Given the line y = x
The slope of the line is 1.
The slope of the line perpendicular is M = -1
Given the point (2,2)
x0 = 2 and y 0 = 2
Substitute
Recall y-y0 = m(x-x0)
y - 2 = -1(x-2) (Point slope form)
Express in slope intercept form;
y - 2 = -1(x-2)
Make y the subject of the formula;
y -2 = -x + 2
y = -x + 2 + 2
y = -x + 4 (slope intercept form)
The general form of linear equation is expressed as the slope intercept form which is y = -x+4
let y = f(x)
f(x) = -x+4
f(x) = 4-x (Linear equation)

Which number line shows the solution to the inequality -2(3x - 1) <8?
I need this please!!!!
Answer:
C
Step-by-step explanation:
I haven't done this math in years but from what I remember this should be the correct answer.
B. is the correct option to choose.
What is inequality ?An inequality is comparing of non-equal terms or expressions.
According to the given question we have to solve the given inequality and represent it in form of a number line with appropriate symbols.
Given,
-2(3x - 1) < 8.
- 6x + 2 < 8.
- 6x < 8 - 2.
- 6x < 6.
- x < 6/6.
- x < 1.
x > -1. ( Think of moving the terms to the other side to make x positive )
This will be represented in a number line with open circle staring from -1 to positive infinity.
