Answer:

X = 2 and 8

Y = 2 and 8

Step-by-step explanation:

Given the simultaneous equation,

log2x + 2log4y =4 ...(1)

log10( x + y ) =1...(2)

find the solution attached.

What is slope between the points (-5,7) and (4,-8)?
WINSTONCH [101]
The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)

Given: △DMN, DM=10 3 m∠M=75°, m∠N=45° Find: Perimeter of △DMN
OlgaM077 [116]

Angle D is 180° -75° -45° = 60°. Drawing altitude MX to segment DN divides the triangle into ΔMDX, a 30°-60°-90° triangle, and ΔMNX, a 45°-45°-90° triangle. We know the side ratios of such triangles (shortest-to-longest) are ...

... 30-60-90: 1 : √3 : 2

... 45-45-90: 1 : 1 : √2

The long side of ΔMDX is 10√3, so the other two sides are

... MX = MD(√3/2) = 15

... DX = MD(1/2) = 5√3

The short side of ΔMNX is MX = 15, so the other two sides are

... NX = MX(1) = 15

... MN = MX(√2) = 15√2

Then the perimeter of ΔDMN is ...

... P = DM + MN + NX + XD

... P = 10√3 +15√2 + 15 + 5√3

... P = 15√3 +15√2 +15 . . . . perimeter of ΔDMN

A, O and B lie on a straight line segment.
Dafna11 [192]

Answer:

x = 36

Step-by-step explanation:

the 3 angles form a straight angle and sum to 180°

sum the 3 angles and equate to 180

3x + x + x = 180 , that is

5x = 180 ( divide both sides by 5 )

x = 36
