Let X be a number of weeks, than you have

(60 + 7 * X) - ( 120 + 5 * X) = 0

Solve for X and you get X = 30 weeks

The key here is to recognize that when they both have equal amounts the difference between their amounts  will be 0c

[] N + (n(t-1)) = T

   I said this because you have N in the first hour, then after that you have n in t hours, which is equal to T. I subtracted one from t, because for the first hour it produces N.

(I think?)

     [] It could also be N + (nt) = T without subtracting 1, but I think subtracting 1 makes sense as I stated above

It's given that WXYZ is a parallelogram. In a parallelogram, the adjacent angles sum up to 180°. Here, 2u - 2 & 3u + 12 together make 180° because they are adjacent angles.

2u - 2 + 3u + 12 = 180

2u + 3u - 2 + 12 = 180

5u + 10 = 180

5u = 170

u = 170/5

u = 34

Answer:

The slope of the fuction is going downwards left. (coordinate plane)

Step-by-step explanation:

It's going downwards left on a coordinate plane because it's going from positives into negatives.

Answer:

The slope is -7/4

Step-by-step explanation:

For every 4 to the right, it goes down by 7. So rise over run so the rise is -7 and the run is 4 so that gets us -7/4

If the domain of the function y 4x + 1 is 0 < x < 10, what is the function's range? ​

Answers

9514 1404 393

Answer:

  1 < y < 41

Step-by-step explanation:

The range of the linear function can be found by looking at the end points of the domain.

  y = 4x +1

  y = 4(0) +1 = 1 . . . . . . at x = 0

  y = 4(10) +1 = 41 . . . . at x = 10

The range is 1 < y < 41.

First we find the slope, which is: 1.

So, then we put the first ordered pair in the formula and the slope.

It will give us y- -1 = 1x(x-4).

Then simply more to equal: y+1=x-4.

i.need help pleaseee and thank uuu

Answers

Step-by-step explanation:

the general line equation is

y = ax + b

a is the slope of the line. it is always the factor of x expressed as ratio y/x. it indicates how many units y changes, when x changes a certain amount of units when going from one point to another.

b is the y-intercept (the y value when x = 0).

so, let's use the 2 given points to find a and b.

(3, 1) to (0, 10)

x changes by -3 units (from 3 to 0).

y changes by +9 units (from 1 to 10).

so, the slope a is 9/-3 = -3

and to get b we would simply pick one point and use its coordinates as x and y values and then solve for b. but the second point gives us already the solution, as its x coordinate is 0 (and therefore its y coordinate is b).

so, the line equation is

y = -3x + 10

1. Slope of line 1: 5/12
Slope of line 2: 12/5
Parallel
Perpendicular
Neither

Answers

Answer:

     

Step-by-step explanation:

Neither

For two lines to be parallel, they must have the same slope, so you know that can’t be the answer

For two lines to be perpendicular, the slope of one would be negative and flipped when compared to the other (e.g. 4/7 and -7/4 or 1/2 and -2)
Since the negative and opposite of 5/12 is -12/5, the two lines can’t be perpendicular, since it is missing the negative

Therefore, Neither is the correct answer

The two graphs that represent proportional relationships are A and C.

What is a proportional relationship?

A proportional relationship is:

y = k*x

Where k is the constant of proportionality.

So, a proportional relationship is a linear equation that passes through the point (0, 0).

With that in mind, we can see that the two graphs that represent a proportional relationship are A and C.
