Answer:
40
Step-by-step explanation:
Emma age: yE = 10 + x (x is timeline)
Father age: yF = A + x (x is timeline, A is Father age today)
in time x1: Emma will be A years old, and Father will be 70 years old.
yE (x1) = 10 + x1 = A
yF (x1) = A + x1 = 70
System of equations with unknown values: x1 and A.
substract equation 1 - equation 2:
10 - A = A - 70 ⇒ 80 = 2A ⇒ A = 40
So, father is 40 years old now
Emma's father is 40 years old
Let the age of Emma father be y
Age of emma = 10 years
In x years time;
Emma age will be 10 + xFathers age will be y + xIf in x1 years time, Emma will be y years old and his father will be 70 years old
Emma age: yE = 10 + x (x is timeline)
Emma's current age will be 10 + x = yHis father;s current age will be y + x = 70
Solving both equations simultaneously;
10 - y = y - 70
10+70 = y + y
80 = 2y
2y = 80
y = 80/2
y = 40 years
Hence Emma's father is 40 years old

intercepts:
y = 1/2x+4
Answer:
y intercept = 4
x intercept = -8
Step-by-step explanation:
0 = x/2 + 4
-4 = x/2
-8 = x
y=mx+b
y = 1/2x+4
Y intercept = b, b= 4

Use the distance formula, to calculate the ratio of a side length on DEF to the corresponding side length on ABC . Show your work. Then confirm your calculations using GeoGebra tools.
Answer: 1.5
Step-by-step explanation:
DE=√(8-5)^2+(-0.5-1)^2 =√11.25≈3.35
AB=√(2-1)^2+(3-1)^2 =√5≈2.24
DE:AB ≈ 3.35 : 2.24 ≈ 1.5

Use the properties of logarithms to expand each logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using a calculator.
Answer:
1/5log2(x)+4/5log2(y)-4/5
Step-by-step explanation:
=log2{(xy^4/16)}^1/5
=1/5×log2(xy^4/16)
=1/5×{log2(xy^4)-log2(16)}
=1/5×{log2(x)+log2(y^4)-log2(2^4)}
=1/5×{log2(x)+log2(y^4)-4)} ( as loga(a^x)=x)
=1/5×log2(x)+1/5log2(y^4)-4×1/5 (distribute 1/5 through the parentheses)
=1/5×log2(x)+1/5×4log2(y)-4/5
=1/5log2(x)+4/5log2(y)-4/5

a carpenter has three sheets of plywood that are each 6.85 feet long. a 3.4-foot piece is cut from one sheet 0.5-foot piece is cut from another piece. How many feet in plywood is left in all
Answer:
16.65 feet
Step-by-step explanation:
Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:
6.85
−
3.4
=
3.45
feet left
If we cut off 0.5 feet off another board, that board has:
6.85
−
0.5
=
6.35
feet left
So, if we take our three new boards, the total length of plywood left is:
6.85
+
3.45
+
6.35
=
16.65
feet
