Answer:
Step-by-step explanation:
there is no soltion because it is not intersects
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
Answer:
1 + 1.5 m less-than-or-equal-to 25
25 greater-than-or-equal-to 1 + 1.5 m
Step-by-step explanation:
Available amount $25
Cost of a song= $1.5
One of fee= $1
Number of songs= m
or
is the required inequality
-----------
Correct answer choices:
- 1 + 1.5 m less-than-or-equal-to 25
- 25 greater-than-or-equal-to 1 + 1.5 m
Answer:
<em>y = -3x + 2</em>
Step-by-step explanation:
From the graph, you see the line intersects the y-axis at y = 2, so the y-intercept is b = 2.
Now we need the slope. We need to find the number of vertical and horizontal units to go from one point to the other. Starting at point (-1, 5), go down 6 units and then go right 2 units. The change in y is -6. The change in x is 2. slope = m = (change in y)/(change in x) = -6/2 = -3.
m = -3; b = 2
y = mx + b
y = -3x + 2
A postulate is a true statement that does not require to be proved . Also called an axiom.
