Answer:
27
Step-by-step explanation:
2x+3x+45=180
5x=135
x=27
Hello,
x²-16x+y²+6y+53=0
==>x²-2*8*x+8² + y²+2*3*y+3²+53-64-9=0
==>(x-8)²+(y+3)²=20
Center is (8,-3) and radius =√20
The partial products are:
42 x 28 = (40 + 2) x (20 + 8)
42 x 28 = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8
42 x 28 = 800 + 320 + 40 + 16
Hope I Helped You!!! :-)
Have A Good Day!!!
Answer:
Slope= 7/5
Step-by-step explanation:
The slope of a line is determined as a ratio of the change in y to the change in x.
Slope=Δy/Δx
Δy=y₂-y₁
Δx=x₂-x₁
Therefore we can use the the x and y coordinates from the points given, (-3,0) and (2,7) to calculate the slope.
m= (7-0)/(2-⁻3)
Slope= 7/5
When a negative number is subtracted from a number it the operation sign changes to addition.
