Answer:
1.9 as a decimal
1 9/10 as a fraction
Step-by-step explanation:
45 + 50 = 95
95/50 = 1 9/10
1 9/10 = 1.9
Ok so we know that y=1 so we can simply sub in the value of y into the equation :
y = -5x +3
1 = -5x +3
Move the -5x to the LHS ( Left-hand-side ) therefore it changes sign as well move 1 to the RHS ( Right-hand-side ) it also changes sign.
5x = 3 - 1
5x = 2
x = 2/5
x = 0.4
Hope this helps :).

Answer:
see explanation
Step-by-step explanation:
Given the polynomial

The rational zeros are all the possible factors of
dived by all the possible factors of
. Therefore we use the rational rots theorem to find all possible rational zeros.
To find all zeros we use the remainder theorem. Thus, we plug in all the rational zeros to determine which ones evaluate to zero. These are the real zeros. We could also use long division to find the remaining zeros as soon as we got the first zero with the remainder theorem.
