For the piecewise function, find the specified function value
if xs1,
(2x-4, if x > 1
f (x) = (-5,
a) Find f(1) =
(1) b) Find f(5) =
(1)
Answer:
f(1) = - 5, f(5) = 6
Step-by-step explanation:
(a)
f(1) with x = 1 is in the interval x ≤ 1 , thus
f(1) = - 5
(b)
f(5) with x = 5 is in the interval x > 1 , thus f(x) = 2x - 4 , so
f(5) = 2(5) - 4 = 10 - 4 = 6
for each recursive sequences below, find a recursive formula for the general term:
e. 2, 3, 6, 18, 108, 1944, ...
f. 1, 2, 6, 24, ...
i’m not sure how to figure these out! please actually answer and give step by step explanation, i will mark brainliest if correct.
Answer:
e(1) = 2, e(n+1) = e(n-1)*e(n) for n > 1f(1) = 1, f(n) = n*f(n-1) for n > 1Step-by-step explanation:
Given sequences e) 2, 3, 6, 18, 108, 1944, ... f) 1, 2, 6, 24, ...To findRecursive formula for the general termSolutionWe can observe that
e) 2*3 = 6, 3*6= 18, 18*6= 108, 108*18 = 1944f) 1*2 = 2, 2*3= 6, 6*4= 24We can put it in general terms as

Solve the inequality.
y - (-5) < 7
Answer:
y > 2
Step-by-step explanation:
a double negative is basically a + sign, so its y + 5> 7, and we want Y alone so we subract 5 from 7 to get Y > 2
Answer:
[tex]y < 2[/tex]
Step-by-step explanation:
[tex]\begin{aligned}y-(-5)+(-5)&< 7+(-5)\\y& <7-5\\y&< 2\\\text{or}\\y-(-5) &= y+5\\\therefore\,y+5& <7\\y+5-5 &<7-5\\y&<2\end{aligned}[/tex]

A line is represented by the equation y = 3x
A The y-intercept is 7.
7. Which of the following statements about the line is TRUE?
B. The line has a positive slope.
C. The point (1,4) lies on the line.
D. This line is parallel to the line whose equation is y - 2x - 7.
Answer:
B
Step-by-step explanation:
the line has a positive slope. you can tell by comparing the equation of the line to y=MX+c where m=slope= coefficient of x.
In this case the coefficient of x is positive 3.

Look at attachment for graph.
Step-by-step explanation:
Solving the inequality just has us isolate the x value.
[tex]-9 + 2x < 1[/tex]
Add 9 to both sides to cancel out -9
[tex]2x < 10[/tex]
Finally, divide both sides by 2 to get rid of the 2 on the x.
[tex]x < 5[/tex]
To graph this, you will just add an open circle on 5 and shade every number to the left of it.
Solve the equation and show your work. M+7-5=20
Answer
18
Step-by-step explanation:
m+7−5=20
Step 1: Simplify both sides of the equation.
m+7−5=20
m+7+−5=20
(m)+(7+−5)=20(Combine Like Terms)
m+2=20
m+2=20
Step 2: Subtract 2 from both sides.
m+2−2=20−2
m=18
Answer:
m=18

Point JJ is located at (5,-3)(5,−3) on the coordinate plane. Point JJ is reflected over the yy-axis to create point J'J ′ . Point J'J ′ is then reflected over the xx-axis to create point J''J ′′ . What ordered pair describes the location of J''?J ′′ ?
Answer:
[tex]J" = (-5,3)[/tex]
Step-by-step explanation:
Given
[tex]J = (5,-3)[/tex]
Reflections: over y and x axis to create J"
Required
Determine J"
When reflected over y axis:
[tex]J'(x,y) = J(-x,y)[/tex]
We have that:
[tex]J = (5,-3)[/tex]
So:
[tex]J(-x,y) = (-5,-3)[/tex]
Hence
[tex]J' = (-5,-3)[/tex]
When reflected over x axis:
[tex]J"(x,y) = J'(x,-y)[/tex]
We have that:
[tex]J' = (-5,-3)[/tex]
So:
[tex]J(x,-y) = (-5,3)[/tex]
Hence
[tex]J" = (-5,3)[/tex]
Answer:
(5,3)
Step-by-step explanation:

2y - 3.5 = 6.5
Answer:
y = 5
Step-by-step explanation:
2y - 3.5 = 6.5
Add 3.5 to both sides.
2y = 10
Divide both sides by 2.
y = 5

in whichvpair of figures can Figure A be taken to Figure B by a rotation?
Pair 1 is the correct answer
What should I type in, in the box
Answer:
No
Step-by-step explanation: No, because each input is not compared to exactly one output. The ordered pair that would need to be removed is (5,7) or (5,8). This works because it means that one of the inputs got taken away and can go to exactly one output.

7x=33 x= simplify your answer please
Answer:
Simplifying
7x = 33
Solving
7x = 33
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '7'.
x = 4.714285714
Simplifying
x = 4.714285714
Step-by-step explanation:
7x = 33
divide both sides by 7
x = 33/7
this fraction cannot be simplified so you can either leave it as
x=33/7
or
simplify to 4.71428571429
or
simplify the decimal to 4.7
