Answer: 25 + 3n
Step-by-step explanation:
Hi, the answer is lacking the last part:
<em>Write an expression for the amount of money he makes this week.
</em>
So, to answer this we have to write an expression:
The fixed amount that he earns per week (25) plus the product of the amount he earns per subscription (3) and the number of subscriptions sold (n) , must be equal to his weekly earnings.
Mathematically speaking:
25 + 3n

Step-by-step explanation:
Distribute -1 across
-t-8=-7.1
-8+7.1=t
t=-0.9
Answer:
Profit=Rs90
Step-by-step explanation:We know that,Profit=Sp-Cp =Rs 810-Rs720 =Rs 90
Answer:
Step-by-step explanation:
f(x) = 5x + 1
Given these two points on the graph of g(x), we must determine the slope, m, of the line. Going from (-4, 2) to (2, 14), x (the run) increases by 6 and y (the rise) increases by 12, so the slope is m = rise/run = 12/6, or m = 2. Adapting the slope-intercept form y = mx + b, we find b as follows:
14 = 2(2) + b, or 14 = 4 + b, or b = 10. Then <em>g(x) is 2x + 10</em>.
Comparing f(x) = 5x + 1, we determine whether each of the four statements is true or false:
A is false; the respective y-intercepts of f and g are 1 and 10.
B is true: the respective y-intercepts of g and f are 10 and 1.
C is false; neither y-intercept is 7.
D is false. 1
Answer:
Step-by-step explanation:
The equation of a line can be written in several forms. Two of the most-used forms are the point-slope and the slope-intercept forms.
The point-slope form requires to have one point (xo, yo) through which the line passes and the slope m. The equation expressed in this form is:
The slope-intercept form requires to have the slope m and the y-intercept b, or the y-coordinate of the point where the line crosses the y-axis. The equation is:
The line considered in the question has a slope m=6 and passes through the point (8,-2). These data is enough to find the point-slope form of the line:
To find the slope-intercept form, we operate the above equation:
