y = -4/5x - 7
Hope this helps give me feedback if im wrong
Answer:
d=7, b -13+7n c 71
Step-by-step explanation:
a= - 6
2nd term=a+(n_1)d
a+d
1+6
=7
b tn a-(n_1)d
_6+(n_1)d
_6 +7n_7
_13+7n
tn a+11d
6+11(7)
6+77
=83
Answer:
16
Step-by-step explanation:
Answer: (2,<u>-5</u>)
Step-by-step explanation:
The slope of the line formed by this set of number is 2 (y increases by 2 for every 1 increase in x). The line has the form y = 2x + b. Enter one of the data points to find b.
y = 2x + b for (2,3)
3 = 2*2 + b
b = -1
The equation is y = 2x - 1
The missing value: y =2*(-2) - 1
y = -5
(2,-5)
Answer:
a = 39.2650873379cm
b = 11.5529459767cm
Step-by-step explanation:
a - Use the area of a triangle equation - 1/2 * a * b * Sin(C)
1/2 * 8 * 10 * Sin(79) = 39.2650873379cm
b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)
64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398
c = square root of 6.9396506484 = 11.5529459767cm
Put to however many significant figures / decimal places required.
