Answer:
(- 8, - 17 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 7 → (1)
y = x - 9 → (2)
Substitute y = 3x + 7 into (2)
3x + 7 = x - 9 ( subtract x from both sides )
2x + 7 = - 9 ( subtract 7 from both sides )
2x = - 16 ( divide both sides by 2 )
x = - 8
Substitute x = - 8 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = - 8 - 9 = - 17
Solution is (- 8, - 17 )
Answer:
3/5
Step-by-step explanation:
12 x
--- = ----
20 5
how do you get from 20 to 5? divide by 4.
12 divided by 4 is 3. The answer is 3/5.
Just think about proportions.
Answer: A sequence of similar transformations of dilation and translation could map △ABC onto △A'B'C'.
Step-by-step explanation:
Similar transformations: If one figure can be mapped onto the other figure using a dilation and a congruent rigid transformation or a rigid transformation followed by dilation then the two figures are said to be similar.
In the attachment △ABC mapped onto △A'B'C' by a sequence of dilation from origin and scalar factor k followed by translation.
Answer:
Step-by-step explanation:
(a) p(2)=(2+2) (2+5) (2-4)
=4*7*-2
=-56
So this is not the polynomial
(b) p(2)=(4-4) (2+5) (2+5)
=0*7*7
0
p(5)=(10-4)(5+5)(5+4)
6*10*9
=540
So this is also not the polynomial
(c)p(2)=(6-2)(2-5)(2-4)
4*-3*-2
24
so this is also not the polynomial
(d)p(2)=(4-4)(2-3)(2+4)
=0
p(5)=(10-4)(5-5)(5+4)
=0
p(-4)=(-8-4)(-4-5)(-4+4)
=0
so this is the polynomial
