Answer:
Its blocked for me.
Step-by-step explanation:
We need to get our equation to this form:
y = mx + b
that is the line equation with m slope and b y-axis intercept. So lets modify our equation:
<span>4x - 5y = 40
5y = 4x - 40
y = (4/5)x - 8
therefore the y-intercept is -8</span>
Answer:
The graph of y = 6x increases at a faster rate than the graph of y = 2x.
Step-by-step explanation:
y=6x and y=2x are proportional relationships of linear functions. It has the form y=mx where m is the rate of change or increase. 6>2 so y=6x will increase faster than 2.
We know the last two statements are not possible because a translation of a graph must be done through addition or subtraction.
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.
Answer:
$25
Step-by-step explanation:
the fruit vendor sold 75-10 = 65 kg of bananas. 65*28 = 1820 dollars. so the fruit vendor earned 1820 dollars.
since she lost 55 dollars, 75 * cost = 1875, divide by 75 to get cost = 25
