evaluate f (x) = -4x + 7 when x = 2 and x = -2
Answer:
- 1 and 15
Step-by-step explanation:
Substitute x = 2 and x = - 2 into f(x)
f(2) = - 4(2) + 7 = - 8 + 7 = - 1
f(- 2) = - 4(- 2) + 7 = 8 + 7 = 15
Rewrite the quadratic expression in vertex form by completing the square. You must show all work.
y = (x^2)-2x + 7
Answer:
[tex]f(x)=(x-1)^{2}+6[/tex]
Step-by-step explanation:
First, subtract 7 from each side.
[tex]-7=x^{2} -2x[/tex]
Now, add in a blank on each side so you can write in your new term that will complete the square. We'll call that term 's' for now.
[tex]-7+s=x^{2} -2x+ s[/tex]
The next step is to take half of the b term, and then square that. In this case, half of '[tex]-2[/tex]' is [tex]-1[/tex]. If we square that we get [tex]1[/tex]. So that is the term we will put in for [tex]s[/tex].
[tex]-7+1=x^{2} -2x+1[/tex]
Simplify:
[tex]-6=x^{2} -2x+1[/tex]
If you look at the right side of the equation, we can factor. That's because we completed the square. We can use the 'guess and check' method to factor. Remember, this is where we use 2 sets of parentheses and fill in the blanks.
[tex]-6=(x-1)(x-1)[/tex]
If we were to FOIL the right side we would end up with [tex]x^{2} -2x+1[/tex].
Since we have 2 '(x-1)' terms next to each other, we can simplify to:
[tex]-6=(x-1)^{2}[/tex]
Now, all we need to do is add 6 to both sides and we have the vertex form.
[tex]f(x)=(x-1)^{2}+6[/tex]
I hope this helps!
Joan has started a physical fitness program. One of her goals is to be able to run at least 5
miles without stopping. She can now run 3.5 miles without stopping. How many more
miles must she run non-stop to achieve her goal?
Answer:
1.5 miles
Step-by-step explanation:
Since Joan need to run 5 miles without stopping and already runs 3.5 miles without stopping, the number of miles more she must run non-stop to achieve her goal of 5 miles without stopping is the difference between her 5 mile goal and her current run of 3.5 miles.
So, number of miles she must run = 5 miles - 3.5 miles = 1.5 miles.
So, Joan must run 1.5 miles more non-stop to achieve her goal.

Answer:
Step-by-step explanation:
Well, the linear equation of a line is:
y=mx+b
Where
m
is the slope and
b
is your y-intercept
So, you can just plug the numbers into the equation
m = − 3
and
b = − 2

Given the function defined in the table below, find the average rate of change, in simplest form, or the function over the interval 20
Answer:
Average rate of change = 0.4
Step-by-step explanation:
Average rate of change of a function in the interval [a, b] is defined by the formula,
Rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the table attached,
Rate of change of the function in the interval 20 ≤ x ≤ 40 will be
= [tex]\frac{f(40)-f(20)}{40-20}[/tex]
= [tex]\frac{24-16}{40-20}[/tex]
= [tex]\frac{8}{20}[/tex]
= [tex]\frac{2}{5}[/tex]
= 0.4
Therefore, average rate change of the function in the given interval 20 ≤ x ≤ 40 is = 0.4
solve for p2. p1v1 = p2v2
Answer:
P₂ = [tex]\frac{P_{1} V_{1} }{V_{2} }[/tex]
Step-by-step explanation:
Given expression:
Boyle's law:
P₁ V₁ = P₂ V₂
Problem is to find P₂;
Solution:
P₁ V₁ = P₂ V₂
To solve this problem, multiply both sides by [tex]\frac{1}{V_{2} }[/tex];
P₁ V₁ x [tex]\frac{1}{V_{2} }[/tex]; = P₂ V₂ x [tex]\frac{1}{V_{2} }[/tex];
[tex]\frac{1}{V_{2} }[/tex] cancels out V₂ on the right hand side;
P₂ = [tex]\frac{P_{1} V_{1} }{V_{2} }[/tex]

A bee flies at 15 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 9 feet per second. It is away from the hive for a total of 16 minutes. A. What equation can you use to find the distance of the flowerbed from the hive? B. How far is the flowerbed from the hive?
9514 1404 393
Answer:
A) d/900 +14 +d/540 = 16
B) 675 feet
Step-by-step explanation:
A) The times are all given in minutes, so it is convenient to use units of feet and minutes in this problem. There are 60 seconds in a minute, so the bee's speeds can be rewritten as ...
15 ft/s = (15 ft/s)(60 s/min) = 900 ft/min
9 ft/s = (9 ft/s)(60 s/min) = 540 ft/min
We know that time is the ratio of distance to speed, so for distance d, we have a total time of ...
d/900 +14 +d/540 = 16
B) To solve the equation, we can subtract 14, then combine the fractions. Here, we choose to combine the fractions in a straightforward way, not being too concerned about "least common denominator." We use the formula ...
a/b + c/d = (ad +bc)/(bd)
(540d +900d)/(900·540) = 2 . . . . subtract 14, combine fractions
d = 2(900)(540)/(1440) = 675
The flowerbed is 675 feet from the hive.

The triangle and the rectangle have the same area
Answer:
w =2.5
Step-by-step explanation:
the area of the triangle is 6*5 divided by half which is 15. this means that the area of the rectangle is also 15. so to find the value of the width we have to divide the area by the known value to get our answer. 15/6 is equal to 2.5 so that's what the value of w is.

Answer:
3(34) + 20 -> Angle 6 = 122
2(34) - 10 -> Angle 3 = 58
Step-by-step explanation:
Since measure of angle 2 is equal to measure of angle 6, and measure of angle 7 is equal to measure of angle 3, we can determine the angle measures for angle 3 and angle 6.
First, we solve for x by adding together the two equations and setting it equal to 180 because of the supplementary angles theorem.
3x + 20 + 2x - 10 = 180
Combine like terms.
5x + 10 = 180
Subtract 10, then divide by 5 on both sides.
5x = 170
x = 34
Now we can plug the x value into the equations.
3(34) + 20 -> Angle 6 = 122
2(34) - 10 -> Angle 3 = 58
