To factor, we need to find out which 2 numbers add up to -10 and multiples to be 21.
The factors of 21 are 1, 3, 7, 21.
From there, we can conclude that -3 + -7 = -10 and -3 * -7 = 21
Hence when you factor the expression, you get:
(x-3)(x-7)
Number 5 am stuck pls help
Answer:
im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*
Step-by-step explanation:
reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3
i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle and that would be your answer
no link or bot yeah that it
Answer:
20 hundredths
Step-by-step explanation:
Because 2 x 10= 20
A Tenth of a number is the value that we get when we divide the number by 10. Similarly, Hundredth is the value we get when it is divided by 100.
Answer:
20
Step-by-step explanation:
2/10 = x/100 -> both sides times 100
20 = x

During football game the ball advanced 4yd, retreated 10 yd, and then advanced 2yd. Where did the ball finish in relation to it’s starting point?
Please explain step by step to get marked!
It moved forward 4 yards, then back 10 yards:
4-10 = -6
It is now -6 yards from where it started.
It then moved 2 yards forward from there:
4-6 + 2 = -4
The ball finished -4 yards from the original location.
Find (f•f)(3)
f(x)=x^-x
Answer:
approximately 1.13
Step-by-step explanation:
[tex](f \circ f) = f(f(3))[/tex]
Working from the inside...
[tex]f(3) = 3^{-3} =\frac{1}{3^3} = \frac{1}{27}[/tex]
Now put this result back into f again.
[tex]f(\frac{1}{27})=\left(\frac{1}{27}\right)^\frac{1}{27}[/tex]
Use a calculator to approximate this; the result is 1.13.
Note: an "exact" answer is [tex]\frac{1}{\sqrt[27]{\frac{1}{27}}}[/tex].

For the function: f(x) = 3x^2 +5x – 8, find and simplify
A. f(x) - f(a) divided by x-a
b.f(x +h) - f(x) all divided by h
Answer:
[tex]f(x) = 3 {x}^{2} + 5x - 8[/tex]
[tex]f(x + h) = 3 ({x + h})^{2} + 5(x + h) \\ = {3x}^{2} + {3h}^{2} + 6xh + 5x + 5h - 8 \\ [/tex]

The graph of a function g is shown below. Find the following:
g(10)
Answer: 8
Step-by-step explanation:
A really simple way to solve these problems is to think of g(whatever number) as the y coordinate on your graph. Therefore the question is basically asking you if x is 10, what is y. If we find 10 on the x axis, we can count up the y axis until we reach the line. So, the answer is 8
Yes you found it correct as per slope intercect form y=mx+b
Here
y=1/2x+5Slope=m=1/2
Y intercect=5
Now.
for g(10)
The coordinate is (10,8)
So
g(10)=8

Answer:
A) 112 3/4 inches
___
B) 5.555 inches
Step-by-step explanation:
Each tile has its own constant width of 2 3/4 in. and length of 5 1/2 in.
The width of the sidewalk is 9 tiles wide; therefore, the width in inches can be found by calculating 9 x 2 3/4
The length of the sidewalk is 25 tiles long; therefore, the width in inches can be found by calculating 25 x 5 1/2
Sidewalk: W = 24 3/4 in. L = 137 1/2 in.
A) L-W
B) L/W
if A x 5 = 10000000 what is A

You can kayak around Hamilton island in 3 hours. Kayaking together, you and your friend can kayak around the island in 1.4 hours. Let t be the time (in minutes) your friend would take to kayak around the island alone. Write and solve an equation to find t.
Answer:
1 / 180 + 1 / t = 1/84
t = 157.5 minutes
Step-by-step explanation:
3hrs = 180 minutes
1.4 hours = 84 minutes
your rate + friend's rate = rate together
1 lap in 180 min + 1 lap in t min = 1 lap in 84 min
The equation is
1 / 180 + 1 / t = 1/84
subtract 1/180 from both sides
1/t = 1/84 - 1/180
1/t = 0.006349206349
multiply both sides by t
1 = 0.006349206349t
Divide both sides by 0.006349206349
1 / 0.006349206349 = t
157.5 = t
t = 157.5 minutes
