3Q + 5 + 2 - 8 - 5 equals 65
Usimov [2.4K]
Answer
 23.70

Proof
3Q+5+2-8-5=65        ~ Simplify
3Q-6=65                      ~Cancel out the six
     +6  +6                      ~Add 6 to both sides since it is a           3Q=71                            negative.
 /3     /3                          ~Cancel out the three.
Answer                         ~Divide both sides by 3
Q=23.66

Q=23.70

What value of b makes the polynomial below a perfect square?
Marina CMI [18]
Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.


-- Remember this only works on perfect square polynomials.

PLEASE HELP!!! Write the equation of a line that goes through the point (6, 3) and is perpendicular to the line y = 4x + 1.
Tpy6a [65]

For this case we have that by definition, the equation of a line in the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It is the slope of the line and (x_ {0}, y_ {0})is a point through which the line passes.

We have the following equation of the slope-intersection form:

y = 4x + 1

Where the slope is m = 4

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope:

m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4}\\m_ {2} = - \frac {1} {4}

Thus, the equation will be of the form:

y-y_ {0} = - \frac {1} {4} (x-x_ {0})

Finally we substitute the given point and we have:

y-3 = - \frac {1} {4} (x-6)

Find f(2), f(1), f(0), and f(-1) for f(x) = 3x + 8.
cupoosta [38]

Answer:

Step-by-step explanation:

Solution

When, x=2

f(2)=3×2+8

=14

Again,

When, x=1

f(1)=3×1+8

=11

When, x=0

f(0)=3×0+8

=8

When, x=-1

f(-1)= 3×(-1)+8

=5
