Answer:
60-15=45 the answer is 45 hours
A linear function is one whose highest power is one (e.g y = mx +c)
A non linear function is one that has powers greater than one (e.g quadratic equations (highest power = 2), cubic equations (highest power = 3), quartic equations (highest power =4))
Y = -3x - 6
Explanation:
to figure out the slope you divide the y-int by the x-int which is -3
You already have the y-int so the answer is y = -3x - 6
Answer:
Infinite number
Step-by-step explanation:
we know that
If one angle is 90°, and another half of that, then it must be 45° and so the third angle is also 45°. (The sum of the internal angles of a triangle must be equal to 180 degrees)
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
therefore
There is an infinite number of unique triangle with these angles.
1. s<span>olve the proportion k/5=5/125.
First reduce 5/125.
5/125 = 1/25
Now you can cross multiply.
25k = 5
k = 5/25
k = 1/5

2. </span><span>round the answer of 0.4x-0.2=2.5 to two decimal places.
</span>0.4x=2.7
x = 6.75
<span>b) -6.75
3. </span><span>what is the y-intercept of 4x-3y=-12?
The y-intercept is when x = 0.
4(0) - 3y = -12
-3y = -12
y = 4
</span>d) 4
