Answer: a = 11.1
<u>Step-by-step explanation:</u>
a(0.3 - y) + 1.1 + 2.4x = 0
Let y = 1.3 → a(0.3 - 1.3) + 1.1 + 2.4x = 0 → -a + 1.1 + 2.4x = 0 → a = 1.1 + 2.4x
(y - 1.2) = -1.2(x - 0.5)
Let y = 1.3 → (1.3 - 1.2) = -1.2(x - 0.5) → 0.1 = -1.2x + 0.6 → -0.5 = -1.2x → 
a = 1.1 + 2.4x

= 1.1 + 0.4(25)
= 1.1 + 10
= 11.1
Answer: C
Step-by-step explanation: because her earnings which means net income is 120 because 15 hours times 8 hours is 120 so she cant make more than that if she gets paid $ 8 for 15 hours.
Answer:

Step-by-step explanation:
The problem needs application of law of indices

This means common power for terms can be applied to each term individually.

Separate power for the terms having same base can be added together.
_______________________________________________________
we will be using these law of indices in the problem

applied the first rule of indices as mentioned above

applied the second rule of indices as mentioned above
Thus, simplified form of (3xy)^2x^4y is
.
Answer:
y - y1 = m(x - x1)
(x1, y1) = (1, -1) (x2, y2) = (3, 5)
m = 
m = 
m =
=
= 3
m = 3
y - 5 = 3(x - 3)
y - 5 = 3x - 9
y = 3x - 9 + 5
y = 3x - 4
Step-by-step explanation:
In order to use point-slope form to convert to slope-intercept form you have to know one point and the value of the slope. In this case, we know two points, but we don't know the slope. In order to find the slope, you can input the values of the two points into the expression: 
After finding the slope, input the values of one of the points (in this example I used (3,5)) and the slope. After that, multiply the slope by the two terms inside the parentheses. then add 5 to both sides of the equation to isolate y. Now your equation is in slope-intercept form.
I hope this helps :)
