Answer:
Hi There the correct answer is {x,y} = {-1,-10}
System of Linear Equations entered :
[1] 3x - y = 7
[2] 4x - 2y = 16
Graphic Representation of the Equations :
y + 3x = 7 -2y + 4x = 16
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 3x - 7
// Plug this in for variable y in equation [2]
[2] 4x - 2•(3x-7) = 16
[2] -2x = 2
// Solve equation [2] for the variable x
[2] 2x = - 2
[2] x = - 1
// By now we know this much :
x = -1
y = 3x-7
// Use the x value to solve for y
y = 3(-1)-7 = -10
Solution :
{x,y} = {-1,-10}
Hope it helps!
Answer:
Step-by-step explanation:
a1 = - 7
d = 4
an = a1 + (n - 1) * d
an = - 7 + (n - 1) * 4
an = - 7 + 4n - 4
an = -11 + 4n
Try this out. Let n = 3
a3 = -11 + 4*3
a3 = - 11 + 12
a3 = 1 Which is what the series says.
Answer:
I think I did this. I think the answer choices are:
Log StartFraction 8 Over 25 EndFraction
StartFraction log 8 Over log 25 EndFraction
log StartFraction 25 Over 8 EndFraction
----> StartFraction log 25 Over log 8 EndFraction
So the answer is D

Step-by-step explanation:
Area of triangle = 1/2 × Base × Height
Mr.Eastman drew triangle JKL,with a height of 12 inches and a base of 12 inches
Area of JKL = 1/2 × 12 inches × 12 inches
= 72 Square inches
triangle XLZ, with a height of 8 inches and a base of 16 inches. Which triangle has the greater area?
