Answer:
y = 17x
$595
Step-by-step explanation:
= = = 17 (find the slope, gradient or rate of change)
The y intercept is 0. Zero hours = 0 charge.
y = 17(35)
y = 595
1st pic
It's a rhombus
- <span>None of the angles are 90 degrees (can't not be rectangle or square)
- Opposite angles are equal
Top triangle
180 - ( 72 + 72 )
=180 - 144
= 36
same as bottom triangle....
-----------------------------------
2nd pic.
Rhombus...
opposite angles are equal
so m<1 = m<2 = 160
180 - 160 = 20
m< 3 = 20/2 = 10
answer
</span>m<2 = 160
m<3 = 10<span>
-----------------------------
3rd pic.
</span> <span>isosceles trapezoid
</span>
<span>The legs are congruent by definition
</span>
so AB = CD
7y - 4 = 8y - 18
7y - 8y = -18 + 4
- y = -14
y =14
answer y = 14

A(-5, -1), B(-9, 6) C (-1, 5) D(3,-2)
A(-5, -1) and C (-1, 5) ---find slope of 1st pair
slope = (5 + 1)/(-1 + 5) = 6/4 = 3/2
B(-9, 6) D(3,-2)---find slope of 2nd pair
slope = (-2 -6)/(3+9) = -8/12= -2/3
slope of 2nd pair (-2/3) is negative and reciprocal of the 1st pair (3/2)
so it's perpendicular
Solution: The function that represents the Grace earning each week is defined as , where is in dollar and is the time in hours. domain of the function is [10,20].
Explanation:
Let, Grace works for h hours per week.
For one hour she get $9.
For h hours she get .
So, the function that represents the Grace earning each week is defined as .
It is given that she works from 10 to 20 hours per week, therefore the value of h lies between 10 to 20. Hence the Grace's earnings for each week is defined as and the domain of the function is [10,20].
