Answer:
y = - 4x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + b ← is the partial equation
To find b substitute (- 2, 5) into the partial equation
5 = 8 + b ⇒ b = 5 - 8 = - 3
y = - 4x - 3 ← equation of line
<h3>I'll teach you how to solve 11X - X2 +4y2 = 52</h3>
-----------------------------------------------------------
11X - X2 +4y2 = 52
Add similar elements:
9x+4*2y= 52
Multiply the numbers 4*2:
4*2= 8
9x+8y= 52
Subtract 8y from both sides:
9x+8y-8y= 52- 8y
Simplify:
9x= 52- 8y
Divide both sides by 9:
9x/9= 52/9 - 8y/9
Simplify:
x=

5 * 8.4 = 42
10^-15 * 10^8 = 10^-7
length = 42 * 10^-7
in scientific notation this is 4.2 * 10^-6
Answer:

Step-by-step explanation:
The two ringtones will cost her a total of
and is a fixed amount. The relationship between the cost and number of songs only is
and therefore the answer is
. You can also directly find the answer by finding the y-intercept (in this case
), as no other answer choices include the term
, so A must be the correct answer.
You would take 3 into 7.5 to get that scale factor.
