if the line joining (3x, x+1) and (11,12) has a slope of 4 what is the value of x
Answer:
x = 3
Step-by-step explanation:
[tex] (3x,\: x +1)=(x_1, \:y_1) [/tex]
[tex] (11,\: 12)=(x_2, \:y_2) [/tex]
[tex]slope = \frac{y_2 - y_1}{x_2 - x_1} \\ \\ 4 = \frac{12 - (x + 1)}{11 - 3x} \\ \\ 4 = \frac{12 - x - 1}{11 - 3x} \\ \\ 4 = \frac{11 - x}{11 - 3x} \\ \\ 4(11 - 3x) = 11 - x \\ \\ 44 - 12x = 11 - x \\ \\ 44 - 11 = 12x - x \\ \\ 33 = 11x \\ \\ x = \frac{33}{11} \\ \\ \huge \red{ \boxed{x = 3}}[/tex]

(8,3) and (-4,-3).
Slope
Answer:
The slope is 1/2
Step-by-step explanation:
The rate of y over the rate of x so it would be y/x. You put the equation y2-y1/x2-x1
Which would look like -3-3/-4-8= -6/-12=6/12 and then you simplify it to 1/2

Transform the given standard form into vertex form and determine vertex.
1.y=x²-4x-3
2.y=x²-7x+2
Answer:
1. the vertex form of your function is f(x)= (x+-2)^2+-7
The vertex is at (2,-7)
2. So, the vertex form of your function is f(x)= (x+-7/2)^2 -41/4
The vertex is at (7/2, -41/4)
Step-by-step explanation:

Y = -1/2x - 2
Step-by-step explanation:
It's due at 11:59PM CST which is around 10 minutes so please take this batch of points and help me out!!
Answer:
y = 2x+ 4
Step-by-step explanation:
The slope of your line given is 2 and it's y-int is 2 that makes the equation y=2x+2.
Since you want a parrallel line you want the smae slope but with a different y intercept. So the answers is y =2x +4.

the perimeter of a rectangular pool is 326 M if the length of the pool is 87 M what is its width
Half the perimeter is equal to the length plus the width.
326 /2 = 163
Length + width = 163
87 + width = 163
Width = 163 - 87
Width = 76 meters

Members of the band are selling candy bars to raise money. The director uses this equation to calculate the amount of profit, p, made from selling n candy bars. p = 1.25n - 475 How many candy bars must be sold to make a profit of $950?
Answer:
380 candy barsStep-by-step explanation:
Step one:
we are told that the expression for profit is
[tex]p = 1.25n - 475[/tex]-----------------1
the above equation represents the situation
given
profit is $950
Required
n=number of bars
950=1.25n-475
collect like terms
950-475=1.25n
475=1.25n
divide both sides by 1.25
n=475/1.25
n= 380candy bars

Answer:
1/8
Step-by-step explanation:
The slope equation for this problem is
y2-y1
--------
x2-x1
So the y2=4, y1=3, x2=8, and x1=0
4-3 =1
----- --
8-0 =8
Which is 1/8
Answer: 1/8
Step-by-step explanation:
Use the slope formula and slope-intercept form
y = mx + b to find the equation.
y = 1/8x + 3

The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees
Answer:
Smallest angle = 40
Step-by-step explanation:
Angle sum property:Sum of all three angles of triangle is 180
2x - 6 + 3x + 5 + 2x + 20 = 180 {Combine like terms}
2x + 3x + 2x - 6 + 5 + 20 = 180
7x + 19 = 180 {Subtract 19 from both sides}
7x = 180 - 19
7x = 161 {Divide both sides by 7}
x = 161/7
x = 23
2x - 6 = 2*23 - 6 = 46 - 6 = 40
3x + 5 = 3*23 + 5 = 69 + 5 = 74
2x + 20 = 2*23 + 20 = 46 + 20 = 66
Smallest angle = 40
Calculate the perimeter of
the triangle with vertices

simplest radical form.
please help !
Answer:
Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]
Step-by-step explanation:
Given, A(-2, -1), B(10, -1), and R(4, 4).
Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]
Distance between A(-2, -1) and B(10, -1) using distance formula:
[tex] \overline{AB} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(10 -(-2))^2 + (-1 -(-1))^2} [/tex]
[tex] \overline{AB} = \sqrt{(12)^2 + (0)^2} [/tex]
[tex] \overline{AB} = \sqrt{(144 + 0)} [/tex]
[tex] \overline{AB} = \sqrt{144} = 12 [/tex]
Distance between B(10, -1) and R(4, 4):
[tex] \overline{BR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 - 10)^2 + (4 -(-1))^2} [/tex]
[tex] \overline{BR} = \sqrt{(-6)^2 + (5)^2} [/tex]
[tex] \overline{BR} = \sqrt{(36 + 25)} [/tex]
[tex] \overline{BR} = \sqrt{61} [/tex]
Distance between A(-2, -1) and R(4, 4):
[tex] \overline{AR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 -(-2))^2 + (4 -(-1))^2} [/tex]
[tex] \overline{AR} = \sqrt{(6)^2 + (5)^2} [/tex]
[tex] \overline{AR} = \sqrt{(36 + 25)} [/tex]
[tex] \overline{AR} = \sqrt{61} [/tex]
Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]
Perimeter of ∆ABR = [tex] 12 + \sqrt{61} + \sqrt{61} [/tex]
Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]
Please answer correctly !!!!!!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!!!!!!!!!
Answer:
I believe it is 14.
Step-by-step explanation:
Answer: The value of x is 14°
Step-by-step explanation:
Since line m is parallel to n, then then the two given angles will have the same measures. Meaning that 136 degrees has to equation (9x+10).
Set them to equal each other and solve for x.
9x + 10 = 136
- 10 -10
9x = 126
x= 14

ABCD is a parallelogram. Work out the size of angle x
Answer:
x=47 degrees
Step-by-step explanation:
X equals 47 degrees because it is congruent to the other angle that is marked. This is because of Alternate Interior Angles.
We know AD and BC are parallel because the shape is a parallelogram, this means that the other line is a transversal. When you have a transversal going through two parallel lines there are certain rules, including Alternate Interior Angles, which are two angles on opposite sides of the transversal but both on the inside of the parallel lines.
Which line has a steeper slope?
Answer:
Line one is the answer
As you see the first line is steeper
Answer:
Line one
Step-by-step explanation:
In order to find the answer to this question simply plot the points on a graph and compare the lines to see which is steeper.
When you plot the points you will see that lines one slope is lower and goes steeper then line two, which means it's your answer.

HELP PLSSSSSSSSSS:( DUE SOON
Answer:
3) x = 21.33
4) x = 33
5) x = 11
Step-by-step explanation:
3: (3x + 17) + (x + 40) + (2x - 5) = 180
6x + 52 = 180
6x = 128
x = 21.333...
4: 180 / 3 = 60
3x - 39 = 60
3x = 99
x = 33
5: 90 + (6x + 7) + (2x - 5) = 180
8x + 2 = 90
8x = 88
x = 11
