Answer (if it is possible check the answer in other sources):
1: y=7x+5.553;
2: y=7x+7.99.
Step-by-step explanation:
all the details can be found in the attachment (the answer is marked with colour).
1) to determine f'(x);
2) to calculate the values x₀ within the given interval;
3) to calculate the values f(x₀);
4) to calculate the values of interception 'i';
5) to write the required equations using 's' and 'i'.
Answer:
x = 41 , y = 139
Step-by-step explanation:
x and 41° are alternate exterior angles and are congruent , so
x = 41
x and y are a linear pair and sum to 180° , that is
x + y = 180
41 + y = 180 ( subtract 41 from both sides )
y = 139
9x^2 - 14x + 20x^2
= 9x^2 +20x^2 -14x
= 29x^2 -14x
