What is the slope of the line that passes through the points A(-2,3) and B(-12,6)?
Answers
Answer:
The answer is
[tex]- \frac{3}{10} [/tex]Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(-2,3) and B(-12,6)
The slope is
[tex]m = \frac{ 6 - 3}{ - 12 - - 2} = \frac{3}{ - 12 + 2} \\ = - \frac{3}{10} [/tex]
We have the final answer as
[tex]- \frac{3}{10} [/tex]

solve for x.
Answers
Answer: x=17
Step-by-step explanation:
7x + 15 = 4x + 66 Subtract 4x from both sides
-4x -4x
3x + 15 = 66 subtract 15 from both sides
-15 -15
3x = 51 Divide both sides by 3
x= 17
50 POINTS NOW!! Which inequality is equivalent to the given inequality plz help
Answers
-4(x + 7) < 3(x - 2)
Let's simplify this inequality
-4x - 28 < 3x - 6
Subtract 3x from both sides and add 28 to both sides
-7x < 22
Answer choice B is correct
Answer:
-7x < 22
Step-by-step explanation:
1. -4(x+7) < 3(x-2)
distribute -4 to x and 7, distribute 3 to x and -2.
2. -4x-28 < 3x-6
add 28 to 28 to cancel it out, add 28 to -6.
3. -4x < 3x+22
subtract 3x from 3x to cancel it out, subtract -3x from -4x.
4. -7x < 22
the final product! the answer is B. -7 < 22. since there was no multiplication or division, there's no need to switch < to >. hope this helps! :)
Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=− 7/9x +14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?
A. In slope-intercept form, the slope is 14/9. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is − C/A.
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
C. In slope-intercept form, the slope is 14/9. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is − C/B.
D. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − B/A.
Answers
Answer:
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
Step-by-step explanation:
Let's convert the standard equation into slope-intercept form:
Ax + By = C ⇒ subtract Ax from both sidesBy = -Ax + C ⇒ divide both sides by By = -A/Bx + C/B ⇒ converted to slope- intercept formAs we see the slope is -A/B
The equation 7x + 9y = 14 is converted as:
y = -7/9x + 14/9, where the slope is -7/9Looking at the answer options and the correct one is option B, where both identification of slopes match.
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.8=4(q-2)+4

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 3 units long. Point C is on the line x = −1. If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.
A: 6
B: 7
C: 8
Answers
Answer:
A. 6
Step-by-step explanation:
Segment AB is on the line y = 2 and is 3 units long.
Point C is on the line x = −1.
FIND:
If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.
SOLUTION:
Area of a triangle = 1/2 b * h
segment AB is a horizontal line
the base of our triangle and point C is somewhere on the height.
If we can find the height of the triangle, we can add or subtract that height from y = 2 to get the possible y coordinate of point C.
We know that the x coordinate is -1 so,
6 = 1/2 (3) h
12 = 3h
h = 4
we can either add 4 or subtract 4 to the y coordinate of 2 to get the possible y coordinate of point C.
option 1
2 + 4 = 6 so the coordinate for C could be (-1, 6) or
option 2
2 - 4 = -2 so the coordinate for C could also be (-1, -2).
Since -2 is not in our choices but 6.
therefore,
the answer would be A. 6

N + 8 = -9 what is “N”
Answers
The equivalent value of the expression is N = -17
Given data ,
Let the equation be represented as A
Now , the value of A is
N + 8 = -9
On simplifying the equation , we get
N + 8 = -9
So , the left hand side of the equation is equated to the right hand side by the value of ( -9 )
Subtracting 8 on both sides of the equation , we get
N = -9 - 8
On further simplification , we get
N = -17
Therefore , the value of N = -17
Hence , the expression is N = -17

∠AOB = 3x° + 46°
∠BOC = 14°
To Find:
Value of x
Step-by-step explanation:
∠AOC = ∠AOB + ∠BOC
90° = 3x° + 46° + 14°
90° = 3x° + 60°
3x° + 60° = 90°
3x° = 90° - 60°

Answer: 78°
Step-by-step explanation:
Looking at the picture, we can tell that ∠ACD and ∠DCB are supplementary angles. This means, they are equal to 180°. With that, we can find x and plug it into ∠DCB.
4x+2+3x+3=180 [combine like terms]
7x+5=180 [subtract both sides by 5]
7x=175 [divide both sides by 7]
x=25
Now that we know x=25, we can plug it in to find ∠DCB.
3(25)+3 [multiply]
75+3 [add]
78
Now, we know ∠DCB is 78°.
[tex] \sf\huge {\dag Question } [/tex]
[tex] \qquad \qquad [/tex] "Diagram"
Determine the value of m∠DCB.
[tex] \sf\huge { \dag Solution } [/tex]
Here, in the diagram it is forming supplementary angle,
[The two angles that gives 180° when they add up are called]
So, we can conclude that,
[tex] \sf { \angle DCA + \angle DCB = 180°} [/tex]
[tex] \sf { 4x + 2 + 3x + 3 = 180°} [/tex] [ Put the values and formed the suitable equation. ]
[tex] \sf { \implies 4x + 3x + 2 + 3 = 180°} [/tex]
[tex] \sf { \implies 7x + 5 = 180°} [/tex]
[tex] \sf { \implies 7x = 180° - 5} [/tex]
[tex] \sf { \implies 7x = 175} [/tex]
[tex] \sf\red { \implies x = \cancel{\dfrac{175}{7}} = 25°} [/tex]
Value of x is 25°.
Now, put the value in the expression 3x + 3 (measurement of m∠DCB)
[tex] \sf { \longrightarrow 3x +3}[/tex]
[tex] \sf { \longrightarrow 3 \times 25 +3}[/tex]
[tex] \sf { \longrightarrow 75 +3}[/tex]
