Answer:
Step-by-step explanation:
hello
calculate x : 3x+2 =5
means : 3x+2-2 =5-2
3x = 3
so : x = 3/3 =1
1 is the element in domain has the image 5 under function f(x)= 3x+ 2
Answer:
x = -1
, y = 5
Step-by-step explanation:
Solve the following system:
{5 x + 3 y = 10 | (equation 1)
x = y - 6 | (equation 2)
Express the system in standard form:
{5 x + 3 y = 10 | (equation 1)
x - y = -6 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 3 y = 10 | (equation 1)
0 x - (8 y)/5 = -8 | (equation 2)
Multiply equation 2 by -5/8:
{5 x + 3 y = 10 | (equation 1)
0 x+y = 5 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{5 x+0 y = -5 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -1 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -1
, y = 5
Answer:
the answer is 1/3
Step-by-step explanation:
3/15 equals 1/5 so 1/5+4/5=1 so 1-2/3=1/3
1) The length of the shadow the tree cast and the shadow Bill cast needs to be added together which makes 34 ft
2) After setting up Bill's Height and Shadow over each other 6ft/9ft.. Set that equal to another proportion...
3) The next proportion is x (the height of the tree) and the length (along the bottom) X/34
4 Solveeee :) 6/9 multiplied by 34 is 22.6- 22 ⅔ft as a fraction
andddd you're done that's the answer
Hope this helpppsss :)
