In the last equation it hast to be on the bottom 43 not just 4
Answer:
C =(43/55)R; C - R = 8t; 48 mi
Step-by-step explanation:
Let C = the distance a coyote can run in t hours.
Let R = the distance a rabbit can run in t hours.
(1) C = 43t
(2) R = 35t
A. <em>Two equivalent expressions
</em>
(a) C/R = 43/35
C = (43/55)R
(b) C – R = 43t – 35t
C – R = 8t
B. <em>Distance advantage of coyote
</em>
Let the difference D = C - R
D = 8t
D = 8 × 6
D = 48 mi
In 6 h, the coyote can run 48 mi further than the rabbit.
In the second step while distributing she made a mistake
It should have been
2x^2 -4x -6x +18 = 9x - 27
So answer should be
She did not use the distributive property correctly
Answer:
Step-by-step explanation:
Use the substitution method
Answers :
g(x)= -3x+1
a. g(10)= -3(10)+1
Mutiply first = -30
-30+1= -29
<em>g(10)= -29</em>
b. g(-2)= -3(-2)+1
Negative sign and negative sign = positive sign
-3(-2)= 6
6+1= 7
<em>g(-2)= 7</em>
a.
f(x)=x^2+7
f(3)= 3^ 2+7
3*3 because of the exponent. 3*3= 9
9+7= 16
<em>f(3)= 16</em>
d.
f(a)= a^2+7
a*a= a^2
a^2+7
<em>f(a)= a^2+7</em>
