Answer:
k = 4
Step-by-step explanation:
Plug in the values of 2 for x and 0 for y, and solve for k.
2x + 3y = k
2(2) + 3(0) = k
4 = k
k = 4
A.) 1/3 - 3(2/7x) - (3)(4) No because - (3)(4) is -12
B.) 1/3 - 6/7x + 12 Yes
C.) -11 2/3 - 6/7x No because 37/3 is 12 1/3
D.) 12 1/3 - 6/7x Yes
E.) 1/3 - 6(1/7x - 2) = 1/3 - 6/7x + 12 Yes
F.) 1/3 + (-3)(2/7x) - (3)(4) No because - (3)(4) is -12
Your answer is B, D, and E

sin(R) = opposite/hypotenuse = ST/RS = 8/10 = 4/5
24
cos(R) = adjacent/hypotenuse = RT/RS = 6/10 = 3/5
25
tan(R) = opposite/adjacent = ST/RS = 8/6 = 4/3
26
sin(S) = opposite/hypotenuse = RT/RS = 6/10 = 3/5
27
cos(S) = adjacent/hypotenuse = ST/RS = 8/10 = 4/5
28
tan(R) = opposite/adjacent = RT/ST = 6/8 = 3/4
Answer:
C. 88 in.
Step-by-step explanation:
This is because the equation for the circumference of a circle is pi times diameter. To get the diameter, multiply the radius by 2. Then do 28*3.14 to get the circumference of the circle then round your answer to get the nearest whole number which is 88 in.
Answer:
4 + 3n
Step-by-step explanation:
Number of seed planed in his garden = 4
Let the Number of seed planted in each neighbor's garden = n
Number of neighbors he has = 3
The total number of seeds planted can be represented by the equation :
Number of seeds planted in his garden + (number of neighbors * number of seeds planted in each neighbors garden)
4 + 3n
