Answer:
∠3=80°
Step-by-step explanation:
∠5=∠2 (alternate angle)
∠5=38
so ∠2=38
∠6=62
∠3+∠6+∠2=180
∠3+62+38=180
∠3=180-100=80
<span>Let g(x) = f(x) - 4
g(x) is a translation of f(x) down 4 units so (-3, 1) will be the new point
find g(-3)
g(-3) = f(-3) - 4
= 5 - 4
= 1
hope this helps</span>
2/7x+6=10. Subtract 6 from both sides
-6. -6
(7/2) 2/7x= 4 (7/2) Multiply both sides by the reciprocal of 2/7
X= 14. The fractions cancels out and x=14
Notice the circle, the radius NM or ML is 5, and the arc the angle makes is 14.3 cm, thus
Y =ax² + bx +c
1) Point (0,7)
7 = a*0² +b*0 +c
c = 7
y=ax² + bx + 7
2) Point (1,4)
4=a*1² + b*1 + 7, ----> 4 = a +b + 7, ------>
a+b= - 3
3) Point (2, 5)
5=a*2² + b*2 + 7, ----> 5=4a+2b +7,---> -2=4a+2b, ---->
-1=2a + b
4)
a+b= - 3, ----> b= -3 - a (substitute in the second equation)
2a+b= -1
2a - 3 - a = -1, ----> a - 3 = -1,
a =2
5) a+b= - 3
2 + b = -3
b = -5
y=2x² - 5x + 7
