Which equation represents a line that passes through (-2, 4) and has a slope of 2/5

Mathematics
1 answer:
Sveta_85 [38]4 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{2}{5}, thus

y = \frac{2}{5} x + c ← is the partial equation

To find c substitute (- 2, 4) into the partial equation

4 = - \frac{4}{5} + c ⇒ c = 4 + \frac{4}{5} = \frac{24}{5}

y = \frac{2}{5} x + \frac{24}{5} ← equation of line

The rhumbas has a perimeter or 16 and height of 3 what is the area ?
daser333 [38]
I think the answer is 15 cuz if the height is 3; 3 on each side is 6 so 6-16=10 and 10 divided by 2 for the two others sides is 5… and 5x3=15

Plz help answer <br> y=2x-3 x+y=18
hram777 [196]
Y = 2x-3 
x + y = 18 
Since you already know what y is equal to, we can plug that in into the second equation. 
x + (2x-3) = 18 
x + 2x -3 = 18 
3x -3 = 18
Add 3 to both sides of the equation. (By doing this, we can isolate the 3x on the left side by getting rid of the -3) 
3x = 21 
Divide 3 on both sides 
x = 7

A^3+a+a^2+1 2a^2+2ab+ab^2+b^3
Vikentia [17]
\frac{a^3+a+a^2+1}{a^3+a^2+ab^2+b^2} \cdot  \frac{2a^2+2ab+ab^2+b^3}{a^3+a+a^2b+b} =\frac{a(a^2+1)+1(a^2+1)}{a^2(a+1)+b^2(a+1)} \cdot  \frac{2a(a+b)+b^2(a+b)}{a(a^2+1)+b(a^2+1)} =\\\\=\frac{(a^2+1)(a+1)}{(a+1)(a^2+b^2)} \cdot  \frac{(a+b)(2a+b^2)}{(a^2+1)(a+b)} = \frac{2a+b^2}{a^2+b^2}

Find the solution set of the inequality<br> 8x−8≤−72.
Ierofanga [76]

Answer:

x≤-8

Step-by-step explanation:

When solving 8x-8≤-72, first add 8 to both sides of the inequality.

This leaves you with 8x≤-64.

Divide both sides by 8: 8x/8 and -64/8

This leaves you with x≤-8 as your solution.
