Answer:
c 89+42x+42y
Step-by-step explanation:
On day 1 :
First Machine= 89 stickers
Second Machine= none
On day 2 :
First Machine= ? stickers ( if in 1min = 42stickers
x min=?
( x min/1 min × 42stickers)
=42x stickers.
Second Machine=?stickers ( if in 1min = 42stickers
y min=?
( y min/1 min × 42stickers)
=42y stickers.
Total = 89 + 42x + 42y
Y = -4x + 7
This is the equation of the line. The slope is -4. The Y- intercept is 7
The expressions are not equivalent, even though Ella got the same result when she substituted zero for f. Then the correct option is C.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
Ella completed the following work to test the equivalence of two expressions.
First expression, Second expression
⇒ 2f + 2.6 ⇒ 3f + 2.6
⇒ 2(0) + 2.6 ⇒ 3 (0) + 2.6
⇒ 0 + 2.6 ⇒ 0 + 2.6.
⇒ 2.6 ⇒ 2.6
The expressions are not equivalent, even though Ella got the same result when she substituted zero for f.
Then the correct option is C.
The complete question is attached below.
