The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

y = -1/2x + 5 is the answer

M = Rise over run meaning you go up 1 and run the other way (left or right) 2

Definition of a Line: A line is 180°

Step-by-step explanation:

Step 1: Set up equation

40° + (2x + 30)° + 40° = 180°

Step 2: Solve for x

Combine like terms: 2x + 110 = 180
Subtract 110 on both sides: 2x = 70
Divide 2 on both sides: x = 35

What is -1 5/6 - (-3 1/4) ?

lions [1.4K]

Answer:

$1\frac{5}{12}$

Step-by-step explanation:

Eliminating a negative and changing our operation

$1\frac{5}{6} +3\frac{1}{4}$

Rewriting our equation with parts separated

$-1-\frac{5}{6} +3+\frac{1}{4}$

Solving the whole number parts

$-1+3=2$

Solving the fraction parts

$-\frac{5}{6} +\frac{1}{4} =[?]$

Find the LCD of 5/6 and 1/4 and rewrite to solve with the equivalent fractions.

LCD = 12

$-\frac{10}{12} +\frac{3}{12}=-\frac{7}{12}$

Combining the whole and fraction parts

$2-\frac{7}{12} =1\frac{5}{12}$

Solve the equation. Write a justification for each step. 5m-3=22

balu736 [363]

Answer:

m=5

Step-by-step explanation:

5m-3=22

take 3 the other side by doing the opposite operation

5m= 22+3

5m= 25

then divide it by 5 on both sides to get the value of m.
5m÷5=25÷5
5and 5 cancels out and the answer becomes :

m=5

Sales of 10000 increased by 65% each year write a function that represents the situation

erastovalidia [21]

Answer: $y=10000(1.65)^x$

Step-by-step explanation:

Given: The sales of 10000 increased by 65% each year .

Let x be the number of years.

The rate of growth=65%= 0.65

The exponential growth function is given by

$y=A(1+r)^x$

, where A is initial amount and r is the rate of growth in decimal.

Then the increase in the sales id given by :-

$y=10000(1+0.65)^x\\\Rightarrow\ y=10000(1.65)^x$
