Angle m∠8 =41° and x=10°
Step-by-step explanation:
Given that m∠3=139° then
m∠3=m∠1 = corresponding angles = 139° and m∠7=m∠5=m∠3=139°
m∠8= 180°-139° =41° -sum of angles on a straight line
m∠8=m∠6=m∠4=m∠2= 41°
2.
Given that m∠3=8x+70° and m∠8=4x-10° then you can find the value of x as;
m∠3+m∠8=180°
8x+70°+4x-10°=180°
12x+60°=180°
12x=180°-60°
12x=120°
12x/12 =120°/12
x=10°
Hence,
m∠3=8x+70° = 8*10 +70° = 80°+70°=150°
m∠8= 4x-10° = 4*10 - 10° = 40°-10° =30°
m∠1 =m∠3 = m∠5 = m∠7 =150°
m∠2 = m∠ 4 = m∠6 = m∠8 =30°

Answer:
c(x) = –8x^2 + 3x – 5 is a quadratic
Step-by-step explanation:
A quadratic function involves the 2nd power of x: x^2, and may (or may not) involve the 1st and zeroth power of x.
a(x) = -2x^3 is not a quadratic because of that exponent 3; in a quadratic, the highest power is always 2.
b(x) = 5x^3 + 8x^2 + 3 is not a quadratic for the same reason that a(x) is not a quadratic.
c(x) = –8x^2 + 3x – 5 is a quadratic: the highest power of x is x^2, the other powers are x^1 and x^0.
Answer:
y = x+5
Step-by-step explanation:
First we find the slope
m = (y2-y1)/(x2-x1)
m = (7-3)/(2 - -2)
=(7-3)/(2+2)
= 4/4
= 1
The slope intercept form is
y = mx+b
y = x+b
Substitute a point in
7 = 2+b
Subtract 2 from each side
5 =b
y = x+5
