HURRY I NEED HELP: Write an equation in point-slope form of the line that passes through the point (3, 5) and has a slope of m=−1.
Answer:
[tex] \huge y - 5 = - 1(x - 3) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question we have the final answer as
[tex]y - 5 = - 1(x - 3)[/tex]

what is 3x+12-6x≤-9 ?
Answer:
[tex]\boxed {x \geq 7}[/tex]
Step-by-step explanation:
Solve the given inequality:
[tex]3x + 12 - 6x \leq -9[/tex]
-Combine both [tex]3x[/tex] and [tex]-6x[/tex]:
[tex]3x + 12 - 6x \leq -9[/tex]
[tex]-3x + 12 \leq -9[/tex]
-Subtract both sides by [tex]12[/tex]:
[tex]-3x + 12 - 12 \leq -9 - 12[/tex]
[tex]-3x \leq -21[/tex]
-When you are dividing an integer by a negative integer, the inequality sign would change. So, divide both sides by [tex]-3[/tex]:
[tex]\frac{-3x}{-3} \leq \frac{-21}{-3}[/tex]
[tex]\boxed {x \geq 7}[/tex] (Final Answer)
Inequalities help us to compare two unequal expressions. The given inequality will be satisfied when the value of x is equal to or more than 7.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The solution for the given inequality can be calculated as shown below,
3x + 12 - 6x ≤ -9
Subtract 12 from both sides of the inequality,
3x - 6x + 12 - 12≤ -9 - 12
Simplifying both sides of the inequality,
-3x ≤ -21
Divide both the sides of the inequality by -3, since division is been done with a negative integer the sign of the inequality will change,
-3x /-3 ≥ -21/-3
x ≥ 7
Hence, the given inequality will be satisfied when the value of x is equal to or more than 7.

O 10°
B
O 50°
(4x)
O 90°
O 180°
(7x-20)
C
Answer:
50 degrees
Step-by-step explanation:
The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°

A line goes through the points (-3 1) and (-2 4)
(a) What is the slope of the line? Show your work.
(b) Write the equation of the line in point-slope form. Show your work.
(c) Write the equation of the line in slope-intercept form. Show your work.
Answer:
Part A)
The slope is 3.
Part B)
[tex]\displaystyle y-1=3(x+3)[/tex]
Part C)
[tex]\displaystyle y=3x+10[/tex]
Step-by-step explanation:
We know that the line goes through the points (-3, 1) and (-2, 4).
Part A)
To find the slope of a line given two points, we can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are our two points.
So, let’s let (-3, 1) be (x₁, y₁) and let (-2, 4) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{4-1}{-2-(-3)}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{3}{-2+3}=\frac{3}{1}=3[/tex]
Hence, the slope of our line is 3.
Part B)
Point-slope form is given by:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is a point.
So, let’s substitute 3 for m.
For our point, we can use either of the two given. Let’s use (-3, 1) for consistency. So, let (-3, 1) be (x₁, y₁). Therefore:
[tex]\displaystyle y-1=3(x-(-3))[/tex]
Simplify. Hence, our point-slope form is:
[tex]\displaystyle y-1=3(x+3)[/tex]
Part C)
To rewrite into slope-intercept form, we can just solve for y from our point-slope form. So, we have:
[tex]\displaystyle y-1=3(x+3)[/tex]
Distribute on the right:
[tex]\displaystyle y-1=3x+9[/tex]
Add 1 to boths sides. So, our slope-intercept equation is:
[tex]\displaystyle y=3x+10[/tex]

Find an equation of a line containing the point (-6,3) and has slope
- 1/3
Answer: y=-1/3x+1
Step-by-step explanation:
To find an equation that contains the given point and has the same slope, we can plug it into slope-intercept form to find the y-intercept.
3=-1/3(-6)+b [multiply]
3=2+b [subtract both sides by 2]
b=1
Now that we know the y-intercept, we know that the equation is y=-1/3x+1.
