What is the slope of the line that passes through the points (10, 2) and (19, 14)?
Write your answer in simplest form.
Answer:
The slope of this line is 4/3.
Step-by-step explanation:
(x1, y1) = (10, 2)
(x2, y2) = (19, 14)
First, find the slope using the slope formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
All this is doing is finding the distance between the y-coordinates and dividing it by the distance between the x-coordinates. I marked these two as points 1 and 2 above, so you can plug in all 4 values and solve:
[tex]m=\frac{14-2}{19-10}\\\\m=\frac{12}{9}\\\\m=\frac{4}{3}[/tex]
The slope of this line is 4/3.

X=
Answer:
X = -2
Step-by-step explanation:
3x - 8/2 = x - 6
3x - 8 = x - 6 × 2
3x - 8 = x - 12
3x - x = -12 + 8
2x = -4
X = -4/2
X = -2

Simplify. Dividing radicals
Answer:
[tex]\frac{\sqrt[4]{15} }{16}[/tex]
Step-by-step explanation:
You cannot leave a radical in the denominator, so the first step is to get rid of it. The way you do that is by multiplying the radical in the denominator by itself over itself because anything over itself is equal to 1. So, for example in this problem:
[tex]\frac{\sqrt{15}}{\sqrt{16} } *\frac{\sqrt{16}}{\sqrt{16} }[/tex]
From here you multiply straight across. The numerator will be equal to [tex]\sqrt{240}[/tex] and the denominator will be 16 because any radical multiplied by itself cancels the radical out and just equals the number inside of the radical. The last step is to simplify the numerator. You do this by finding factors of 240 which are:
1 * 2402 * 1203 * 804 * 605 * 486 * 408 * 3010 * 2412 * 2015 * 16You want to use the greatest factor you have so you can break it down easier which in your case is (15 * 16). From here you simplify each of those numbers until you have a duplicate of something. The greatest factor of 15 is 3 * 5, so that won't simplify because there are no duplicate numbers. The greatest factor of 16 is 4 * 4 which means that it will simplify. When you are simplifying the duplicate (4) always goes outside of the radical and the non-duplicate (15) always goes on the inside of the radical. Your answer should look like this:
[tex]\frac{\sqrt[4]{15} }{16}[/tex]

Answer:

Step-by-step explanation:
If we express $3x^2 - 6x - 2$ in the form $a(x - h)^2 + k$, then what is $a + h + k$?
If we express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], then a + h + k = -1
The given quadratic expression is:
[tex]3x^2-6x-2[/tex]
To express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], follow the steps below
Rewrite [tex]3x^2-6x-2[/tex] as [tex]3x^2-6x+3-5[/tex]
Factorize common terms
[tex]3(x^2-2x+1)-5[/tex]
This can be further simplified as:
[tex]3(x-1)^2-5[/tex]
Therefore, the vertex form of the equation [tex]3x^2-6x-2[/tex] is [tex]3(x-1)^2-5[/tex]
Compare [tex]3(x-1)^2-5[/tex] with [tex]a(x-h)^2+k[/tex]
a = 3, h = 1, k = -5
a + h + k = 3 + 1 - 5
a + h + k = -1
Therefore if we express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], then a + h + k = -1

Find the length of the third side. If necessary, round to the nearest tenth.
Answer:

Given m | n, find the value of x and y.
X = 23
Y = 129
Hope this is helpful!
Answer:
i think x = 23, y = 129
Step-by-step explanation:
5x+14+3x-18 = 180
8x-4 = 180
8x = 184
x = 23
3x-18+y = 180
3(23)-18+y = 180
69-18+y = 180
51+y = 180
y = 129

Step-by-step explanation:
Answer:
y = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 6 when x = - 7
6 = - 7k ( divide both sides by - 7 )
- [tex]\frac{6}{7}[/tex] = k
y = - [tex]\frac{6}{7}[/tex] x ← equation of variation
When x = 4 , then
y = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]

You want to save at least $180 to buy a new phone. You already have $65 in your account, and you can save $23 a week from your after-school job. Which inequality can be used to find the minimum number of weeks you need to save before you can purchase the phone?
Answer: 180≤23x+65
Step-by-step explanation:
p = phone
w = weeks
65 + 23w ≥ 180
If you need it to be solved, the minimum number of weeks goes as shown:
65 + 23w ≥ 180
-65 -65
23w ≥ 115
/23 /23
w ≥ 5
So, the minimum number of weeks that is required is 5.
