Step-by-step explanation:
Hey there!!
Given,

Comparing it with ax^2+bx+c =0 we get,
a= 1, b= 8, c= -5.
Using formula,

Keep all values,




Taking negative,



Similarly, taking positive,



Therefore, x= (4 + root 21, 4 - root 21).

Answer:
14 5/8
Step-by-step explanation:
I took the test
We have that
<span>the point (7, 1)
case </span><span>A.) y = 5x + 4
if the point </span>(7, 1) lie to the line
so
for x=7 the value of y must be 1
y=5*7+4------> y=39
39 is not 1---------> the point does not belong to the line
case <span>B.) y = -x + 8
</span>if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=-7+8------> y=1--------> the point belongs to the line
case <span>C.) y = x - 10
</span>if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=7-10------> y=-3
-3 is not 1---------> the point does not belong to the line
case <span>D.) y = -4x + 3
</span>if the point (7, 1) lie to the line
so
for x=7 the value of y must be 1
y=-4*7+3------> y=-25
-25 is not 1---------> the point does not belong to the line
the answer is the option
B.) y = -x + 8
Answer:
The 45 in snake is the shorter one.
Step-by-step explanation:
Which is shorter, 45 in or 4 1/2 ft?
12 in
Convert 4 1/2 ft into inches by multiplying 4 1/2 ft by --------- = 54 in.
1 ft
Thus, the 45 in snake is shorter than the 54 in one and should b e V's first choice.
