Answer:
f(x) = 4/7x + 20/7
Step-by-step explanation:
If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:
<u>(first y-coordinate - the second y coordinate)</u>
(first x-coordinate - second x coordinate)
= <u>(0 - 4)</u>
(-5 - 2)
= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.
Thus, the answer is f(x) = 4/7x + 20/7
Answer:
The points are: (16.12,0),(-8.12,0).
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
Distance between two points:
Suppose we have two points, 
and 
. The distance between them is given by:
Find all points on the x-axis that are 14 units from the point (4, -7).
Being on the x-axis mean that they have y-coordinate equal to 0, so the point is (x,0).
The distance is 14. So
So 
The points are: (16.12,0),(-8.12,0).
True, 2 squares gives four, therefore it's true Hope I helped :)
Answer:
Math expression= L[m]= W[g] / R[g/m]
answer=4.606Km
Step-by-step explanation:
It is known that the cable weighs 44kg / km therefore if the weight is divided by this amount we can find how much cable length was spent
L=W/R
L= leght of wire used(m)
W=weight used(g)=205g
R= relation between weight and leght(g/m)=44.5g/km=0.0445g/m
L=205g/0.0445g/m= 4606.74m= 4.606Km
