Slope =10/12=5/6
y=(5/6)x+b
6=(5/6)*18+b    (18,6)
6=15+b
b=-9

y=(5/6)x-9
30=(5/6)x-9


39=(5/6)x
x=39*6/5≈46

correct answer 45

in principle, you can look and see, that all other answers too low, even 42 gives 27
so 30 should be higher

Which set of rational numbers is arranged from least to greatest? 1 over 5, −1.4, negative 1 over 2, 3 3, negative 1 over 2, −1.
Mars2501 [29]

Answer:

Option 4 - -1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3

Step-by-step explanation:

To find : Which set of rational numbers is arranged from least to greatest?

Solution :

The set of rational numbers are

3,\ \frac{1}{5},\ -1.4,\ -\frac{1}{2}

Writing all number in one form,

\frac{1}{5}=0.2

-\frac{1}{2}=-0.5

Now, -1.4<-0.5<0.2<3

From least to greatest the set of natural numbers are

-1.4

So, -1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3

Therefore, option 4 is correct.

Solve the following system of equations by graphing and select the correct answer below:
JulijaS [17]

Answer: option c

Step-by-step explanation:

Find the x-intercept and y-intercept of each line.

To find the x-intercept, substitute y=0 into the equation and solve for "x".

To find the y-intercept, substitute x=0 into the equation and solve for "y".

- For the first equation:

x-intercept

4x + 3y = 29\\\\4x + 3(0)= 29\\\\4x=29\\\\x=\frac{29}{4}\\\\x=7.25

y-intercept

4x + 3y = 29\\\\4(0) + 3y = 29\\\\3y=29\\\\y=\frac{29}{3}\\\\y=9.66

Graph a line that passes through the points (7.25, 0) and (0, 9.66)

- For the second equation:

x-intercept

2x - 3y = 1 \\\\2x - 3(0) = 1 \\\\2x=1\\\\x=0.5

y-intercept

2x - 3y = 1\\\\2(0) - 3y = 1\\\\-3y=1\\\\y=-0.33

Graph a line that passes through the points (0.5, 0) and (0, -0.33)

Observe the graph attached. You can see that point of intersection of the lines is (5,3); then this is the solution of the system. Therefore:

x=5\\y=3
