Which is true about the solution to the system of inequalities shown? y > 3x + 1 y 3x + 1 are solutions. Only values that sat
olga nikolaevna [1]

Answer:

The correct option is;

There are no solutions

Step-by-step explanation:

From the graph of the inequality, with the y-intercept = 1 and slope = 3 for the blue shaded inequality

The equation is y > 3x + 1

While that of the other red shaded inequality, the slope is 3 and the y-intercept = -3

The equation is y < 3x - 3

Given that the two inequalities are parallel line that their domains do not overlap, we have that there are no solutions as the y-coordinate values of  y > 3x + 1 are always larger for a given x-coordinate value than the y-coordinate value of y < 3x - 3.

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The mon
kupik [55]

Answer:

The cost is;

$18.43

Step-by-step explanation:

The general model for a linear equation is;

y = mx + b

let y be the monthly cost in dollars

x is the number of minutes

b will represent the base cost

m is the cost of the call per minute

so let us get m and b

Thus, we have;

18.25 = 31m + b

19.42 = 44m + b

Subtract i from ii

(19.42-18.25) = (44-31)m

1.17 = 13m

m = 1.17/13 = 0.09

To get b, we substitute the value of m in any of the equation

18.25 = 31 m + b

18.25 = 31(0.09) + b

b = 18.25 - 2.79

b = 15.46

so, the equation of the line is;

y = 0.09x + 15.46

Now to get the cost for 33 minutes

simply substitute the value of 33 for x

we have this as;

y = 0.09(33) + 15.46

y = $18.43

4x + 7y = 3 x = y - 2
liberstina [14]

First equate 4x+7y=3x,

we get, x+7y=0 ---->equ 1

Now equate 3x=y-2, we get 3x-y=-2 ----->equ2

solve equ 1,2,

We get x= -7/11, y=1/11

The asymptote of the function f(x) = 3x + 1 – 2 is ___. Its y-intercept is ___.
Svetradugi [14.3K]
The only way this could have an asymptote, either horizontal, vertical, or oblique is if it is a rational function, proper or improper. This function is linear:
y=3x-1 is what it simplifies to and it is a straight line through the y axis at -1 and has a positive slope of 3. There are no asymptotes here. But the y intercept, like I stated, is (0, -1)

8th grade math help!!
horsena [70]

Step-by-step explanation:

A = 1/2h(b1 + b2)

2A = h(b1 + b2)

h(b1 + b2) = 2A

h = 2A/(b1 + b2)
