Answer:
46
Step-by-step explanation:
The length of base CD is twice the length of midsegment FG, so you can write the equation ...
CD = 2×FG
-3x +52 = 2(13 +5x)
52 = 26 +13x . . . . . . . . add 3x, simplify
26 = 13x . . . . . . . . . subtract 26
2 = x . . . . . . . . . . divide by 13
Then the measure of CD is ...
CD = -3x +52 = -3(2) +52 = -6 +52
CD = 46
By the table, it seems to be that f = 1/2x
Answer:
1400
Step-by-step explanation:
Example: Halve 28 and double 50, obtaining 14 and 100; then mult. 14 and 100 to obtain 1400 (answer)
y = (8 + x)4
Step-by-step explanation:
- Step 1: Given output is y. Let the input be x. Form equation based on the information given - output is 2 more than 1/4th input
⇒ y = 2 + 1/4x = (8 + x)/4
Answer:
Step-by-step explanation:
1) y=x²-8x+5=0
2) x²-8x=-5
3) x²-8x+16=9
4) (x-4)²=9
5)(x-4)²-9=0
((x-4)-3)((x-4+3)=0
(x-7)(x-1)=0
x=7 or x=1
