Step-by-step explanation:
14y-1=11y+17 subtract 11y from both sides
3y-1=17 add 1 to both sides
3y=18, divide both sides by 3
y=6
Since DG=EF
EF=9y+4 and using y=6
EF=9(6)+4
EF=54+4
EF=58

y = x - 16
5y = 2x - 56
Step 2: Solve for x
Substitute in y: 5(x - 16) = 2x - 56Distribute 5: 5x - 80 = 2x - 56[Subtraction Property of Equality] Subtract 2x on both sides: 3x - 80 = -56[Addition Property of Equality] Add 80 on both sides: 3x = 24[Division Property of Equality] Divide 3 on both sides: x = 8Step 3: Solve for y

The first two terms of a sequence are a1 =4 and a2= -2. Let a3 be the third term when the sequence is arithmetic and let b3 be the third term when the sequence is geometric. Find a3+b3
Answers
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7

Angel is saving all of his money for a ticket to Grad Bash. Before he started working, he had $7.50 in his bank account On Saturday, he works 5 hours and earns $42.50 On Sunday, he works 8 hours and earns $68,00
Which of the following functions models Angels savings?
Answers
Answer:
The second choice is correct. (f(x) = 8.50x+7.50)
Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

y=−4x−3
y=−2x+1
x=x=x, equals
y=y=y, equals
Answers
Answer:
x = -2, y = 5.
Step-by-step explanation:
y=−4x−3
y=−2x+1
Because y is common to both left sides:
-4x - 3 = -2x + 1
-4x + 2x = 1 + 3
-2x = 4
x = 4/-2
x = -2.
So y = -4(-2) - 3
= 8 - 3
= 5 .
