Write a linear equation for thw line that goes through the point (2,5) and has a slope of 2.
Answers
Given:
Point; (x, y) ==> (2, 5)
Slope, m = 2
To write a linear equation that goes through the point, apply the slop-intercept form:
y = mx + b
Where m is the slope and b is the y-intercept.
Take the following steps:
• Step 1:
Substitute 2 for m.
Input the points (2, 5) for the values of x and y repsectively
y = mx + b
5 = 2(2) + b
5 = 4 + b
• Step 2:
Solve for b.
Subtract 4 from both sides
5 - 4 = 4 - 4 + b
1 = b
Therefore, to write the linear equation, substitute 2 for m, and 1 for b in (y = mx + b)
y = mx + b
y = 2x + 1
Therefore, the equation for the line that goes through the point (2, 5) and has a slope of 2 is:
y = 2x + 1

[tex]y=2x+1[/tex]

Which is the graph of the function f(x) = x3 + x2 + x + 1?

Answer:
Step-by-step explanation:
Clues to recognize the graph:
-The graph will cross from the first quadrant into the third quadrant.
-The graphs of cubed equations are looking like an S shape.
-The graph must cross at y = 1 because when x is zero y is 1
If x=0 in our equation y= x^3 + x^2 + x + 1 will be y=1
-The graph must have a zero at x= -1 because if we rewrite the equation
y= x^3 + x^2 + x + 1 = (x+1)(x²+1) and here we see that one of the roots or zeros is (x+1) = 0, x= -1

The height of the triangle is 3 inches.

Given:
[tex]\begin{gathered} \text{Base of the triangle}=3\frac{2}{5}\text{ inches} \\ \text{Area of the triangle}=5\frac{1}{10}\text{ inches} \end{gathered}[/tex]We change the mixed fractions to improper fractions below:
[tex]\begin{gathered} \text{Base of the triangle}=3\frac{2}{5}=\frac{(5\times3)+2}{5}=\frac{17}{5}\text{ inches} \\ \text{Area of the triangle}=5\frac{1}{10}=\frac{(10\times5)+1}{10}=\frac{51}{10}\text{ inches} \end{gathered}[/tex]We want to find the height of the triangle.
Recall that the area of a triangle is calculated using the formula below.
[tex]\text{Area}=\frac{1}{2}\times\text{Base}\times Height[/tex]Substitute the given values:
[tex]\frac{51}{10}=\frac{1}{2}\times\frac{17}{5}\times\text{Height}[/tex]Multiply the numerators and denominators on the right side of the equation.
[tex]\begin{gathered} \frac{51}{10}=\frac{1\times17}{2\times5}\times\text{Height} \\ \frac{51}{10}=\frac{17\times\text{Height}}{10} \end{gathered}[/tex]Multiply both sides by 10.
[tex]\begin{gathered} \frac{51}{10}\times10=\frac{17\times\text{Height}}{10}\times10 \\ \implies51=17\times\text{Height} \end{gathered}[/tex]To solve for the height, divide both sides by 17.
[tex]\begin{gathered} \frac{51}{17}=\frac{17\times\text{Height}}{17} \\ 3=\text{Height} \\ \text{Height = 3 inches} \end{gathered}[/tex]The height of the triangle is 3 inches.

Your brother has 2,000 dollars saved for a vacation. His airplane ticket is 637 dollars. Write and solve an inequality to find out how much he can spend for everything else.
Answers
If x variable represents the money your brother has without the value of the airplane ticket, then, the expression x + 637 is the total money he has at the beggining.
In the sense of an inequality, it means x + 637 must be lower or equal than 2000 dollars, which was the initial money yoir brother had.
Then, you have:
x + 637 ≤ 2000
to solve the previous inequality, subtract 637 both sides:
x + 637 - 637 ≤ 2000 - 637 simplify both sides
x ≤ 1363
Hence, the solution to the ineuqality is x ≤ 1363
