Step-by-step explanation:
RS = 15/ tan57° = 9.7
RT = 15/sin57° = 17.9
Answer:
the answer is -Xax.
Step-by-step explanation:
F(x)=3x^2+6x-8
Formula: a=-b/2(a)
a=-6/2(3)=-3
I guess the answer is d)
Answer: A false, B true, C true
Step-by-step explanation:
A) intercept with y axis
That means x=0
y= 3*0-2
y= -2 So A is false
B) intercept with x axis
That means y=0
0= 3x-2
2=3x
2/3= x B is true
C) The form of linear function is
f(x)= mx +n, where m is the slope
In this case m= 3 so C is true
Answer:
Yes, the point makes the inequality true
Step-by-step explanation:
y < 10x+8
Substitute x =9 and y=8 into the inequality
8 < 10*9+8
8<90+8
8<98
This is true so the point makes the inequality true
