Answer:
Find the attached
Step-by-step explanation:
We are given the following linear equation;
-3y = 2x - 7
In order to graph it, we need to determine at least 3 pairs of points that lie on the line;
we first solve for y by dividing both sides of the equation by -3;
y = (-2/3)x + 7/3
let x be 3;
y = (-2/3)*3 + 7/3
y = 1/3
(3, 1/3)
let x be 6;
y = (-2/3)*6 + 7/3
y = -5/3
(6, -5/3)
let x be 9;
y = (-2/3)*9 + 7/3
y = -11/3
(9, -11/3)
Using the three set of points we graph our linear function. Find the attached;
Answer:
1.03
Step-by-step explanation:
When you increase a quantity by 3%, you end up with 103% of it. The decimal for 103% is 1.03 (one and three hundredths).
Example: Increase $6.00 by 3%
(6.00)(1.03) = 6.18
Answer:
Use the given formulas and replace s with its value of 5 inches.
<u>So the volume:</u>
<u>Total surface area:</u>
4.6 moles in 187 grams of magnesium oxide (mgo).
<h3>What is mole explain with example?</h3>
- One mole is defined as the amount of substance containing as many elementary entities (atoms, molecules, ions, electrons, radicals, etc.) as there are atoms in 12 grams of carbon - 12(6. 023×1023).
- The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
- The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula.
- Moles are units used to measure substance amount. Chemistry (Single Science) Atomic structure.
To solve ,
number of moles is equals to the mass in grams divided by RFM
RFM=16+24.3=40.3
=187/40.3
=4.6 moles of MgO

The value of the expression in the simplified form is f(x) = x+3/x-3
<h3>Rational expression</h3>
Rational expressions are expressions written as a ratio of two integers or expressions.
Given the rational expression below;
f(x) = x²+5x+6/x²-x-6
Factorize the numerator and denominator
f(x) = x²+3x+2x+6/x²-3x+2x-6
f(x) = x(x+3)+2(x+3)/x(x-3)+2(x-3)
f(x) = (x+3)(x+2)/(x+2)(x-3)
f(x) = x+3/x-3
Hence the value of the expression in the simplified form is f(x) = x+3/x-3
