4 is equal to 2*2 (double the 2 is 4)
Answer:
Step-by-step explanation:
short explanation: 1) to add the 1st equation to the 2d; 2) to calculate the value of 'x', then to substitute x=13/5 into the 2d equation and calculate the value of 'y'.
Answer:
19.7 or 20 rounded
Step-by-step explanation:
A = $ 1,861.65
A = P + I where
P (principal) = $ 630.00
I (interest) = $ 1,231.65
Continuous Compounding Formulas (n → ∞)
Calculate Accrued Amount (Principal + Interest)
A = Pe^rt
Calculate Principal Amount, solve for P
P = A / e^rt
Calculate rate of interest in decimal, solve for r
r = ln(A/P) / t
Calculate rate of interest in percent
R = r * 100
Calculate time, solve for t
t = ln(A/P) / r
Although this problem can be solved easily if given the
figure, we can simply imagine to solve this. We see that we are given two
points of the quadrilateral which are (2, 4) and (2, 3). This means that from P
to Q, there is only a distance of 1. Since a quadrilateral has 4 equal sides
therefore the perimeter is 4 units.

The solving linear equation states that the temperature of the oven is 119 after an minute.
<h3>What is a linear equation?</h3>
A linear equation is just an algebraic equation of something like the form y=mx+b that only contains a constant and a first-order (linear) component, where m represents the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are now the variables.
<h3>According to the given data:</h3>
Given:
y = 40x+79
X = number of minutes using it to bare:
When X = 1
y = 40(1)+79
y = 119
It means that the temperature of the oven is 119 after an minute.
