Given the function f(x) = 3x + 1, what is the value of f(9)
f(x) = 3x + 1
f(9) = 3(9) + 1
f(9) = 27 + 1
f(9) = 28
f(9) = 28. I hope this helps! I have a g00gle classroom where I help with algebra including this. If you are interested, please consider joining. I will post the class code in the comments if it would let me. Sorry it wouln't let me type g0ogle properly.
Answer:
28
Step-by-step explanation:
f(9) means when x = 9.
when x = 9,
f(9) = 3(9) + 1
= 27 + 1
= 28
Cole wrote the number shown.
375,819
Lindsay used the same digits to write a number in which the value of the digit 7 is 110 of the value of the digit 7 in Cole’s number. Which number can be the one Lindsay wrote
I have no idea how to answer this question I've tried everything look at the Picture
Answer:
a. the error is that he wrote 0.05 instead of 0.2
0.148835 ≈ 0.2
b.
0.2 = 2 × 0.1
0.2 = 2 × 10⁻¹
The mass is about 2 × 10⁻¹ kg
Any ways i need help (16 points)
Answer:
Step-by-step explanation:
A = 3M
J = 2A
J = 6M
Marie = M
Andre = 3M
Jane = 6M
6M+3M+M = 840
10M = 840
M= 84 Pounds
Andre = 3M
Andre = 84*3
Andre has 252 pounds of apples.
y = {(x+6) - 5
m=
b=
Answer:
m=1/2 & b=-2
Step-by-step explanation:
so in order to find m & b we need to distribute 1/2
y=1/2(x+6)-5
y=1/2x+3-5
y=1/2x-2
y=mx+b so
m=1/2 & b=-2
Answer: i dont know where u got m and b from but y=[tex]\frac{x}{2}[/tex] abd x= 2y+4 :)

Mr. Davis is packing a box with books. The box is a rectangular prism with the 2 ft 3 ft 2 ft What is the volume of the box?
Answer:
12 ft^3
Step-by-step explanation:
Given data
Dimension
Lenght= 2ft
Width= 3ft
Height= 2ft
The expression for the volume is
Volume= L*W*H
Substitute
V= 2*3*2
V= 12 ft^3
Hence the volume of the box is 12 ft^3
Hal put $3000 into a savings account that earns 6% interest. After 6 years, what will be the total amount of money in his savings account?
Explain for BRAINLIST.
Answer:
6000
Step-by-step explanation:
so you have to divide 3000 and 6 to get 500
next you would do 500 times 6 equals = 3000
so now you would plus them and get 6000
now that is your answer

A function is shown f(x) = 2/3x + 3
What is the value of f(12)?
Answer:
f(12) = 11
Step-by-step explanation:
To evaluate f(12) substitute x = 12 into f(x) , that is
f(12) = [tex]\frac{2}{3}[/tex] × 12 + 3 = 8 + 3 = 11

Answer:
any number between 83 and 0. [tex]0\leq x\leq 83[/tex]
Step-by-step explanation:
the number 1,548.4484 has the last two digits of 84.
And since the number has to be less than the other number and you can only switch the last two digits in the decimal's place. It has to be less than 84
Hope that helps :)
Answer:
the digit is 4, because that has 4484 but just put 4444
Find the trigonometric ratios as simplified fractions and as decimals to the nearest thousandths (as necessary).
Sin X: Fraction_______ Decimal_______
Cos X: Fraction_______ Decimal______
Tan X: Fraction__________ Decimal______
Step-by-step explanation:
by using Pythagoras law
ZY=√{45²-27²)=36
sin X=ZY/XY=36/45=0.8
Cos X=XZ/XY=27/45=0.6
Tan X= YZ/XZ=36/27=1.33
Sam paid $8.28 for 18 stamps. At this rate, how much would it cost Sam to buy 12 stamps?
Answer: $5.52
Step-by-step explanation:
Given: Sam paid $8.28 for 18 stamps.
Thus, the cost of 18 stamps = $8.28
Then the cost of 1 stamp=
Thus, the cost of 1 stamp=$0.46
With the same rate , the cost of 12 stamps=
Therefore, the cost of 12 stamps= $5.52
hence, it costs $5.52 to Sam to buy 12 stamps.
8.28÷18 = 0.46
0.46 is the cost if 1 stamp
cost of 12 stamps= 0.46×12 = $5.52

The graph shows the relationship between the number of apples and their cost. For the point (1, r), what is the value of r?
Answer:
C.
Step-by-step explanation:
When you check the point that is on X, it is a little over halfway to the point 1,2. It would be like 1,1.5 or 1,1.6.
5/3 is the equivalent to 1.6 so that answer would make the most sense.
Answer:
5/3
Step-by-step explanation:
3 Apples cost $5, so each apple cost 5 divided 3 ( 5 over 3).
Please help.
Is algebra.
Answer:
B
Step-by-step explanation:
The first one is a binomial. It has two different terms on either side of the middle minus sign. y is raised to the 4 th power so that is degree 4. The answer is b
The second problem is ordered as 4 3 1 2
The powers determine the degree. The terms are all different and the number of terms is determined by the powers of the letters in the terms.

Step-by-step explanation:
Angle X and Angle Y are complementary angles. Given Angle Y is equal to 1/5th Angle X. Find the value of Angle X in degrees
Answer:
75 degrees
Step-by-step explanation:
Complementary angles equal 90 degrees together. That is the case with angle X and Y. Set an equation to describe the situation.
Y=1/5X
X=5Y
Now, set another equation:
X+Y=90
Substitute the first equation into the second one.
5Y+Y=90
6Y=90
Y=15
Substitute this once again:
X+15=90
X=75

Find the slope of the line through each pair of points using the formula.
(17, -19) (4, -15)
Answer:
-4/13
Step-by-step explanation:
(17 , -19) ; (4 , -15)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{-15-[-19]}{4-17}\\\\=\frac{-15+19}{4-17}\\\\=\frac{4}{-13}\\\\= \frac{-4}{13}[/tex]

Find the value of x.
44 °
Х
x = [? ]°
Answer:
x = 136°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, that is
x + 44° = 180° (subtract 44° from both sides )
x = 136°
Can y’all help with geo?
Here's the solution,
figure 1.
by using trigonometry,
=》
[tex] \sin(60) = \dfrac{5 \sqrt{3} }{y} [/tex]
=》
[tex] \dfrac{ \sqrt{3} }{2} = \dfrac{5 \sqrt{3} }{y} [/tex]
=》
[tex] \dfrac{1}{y} = \dfrac{ \sqrt{3} }{2 \times 5 \sqrt{3} } [/tex]
=》
[tex] \dfrac{1}{y} = \dfrac{1}{10} [/tex]
=》
[tex]y = 10[/tex]
And,
=》
[tex] \cos(60) = \dfrac{w}{y} [/tex]
=》
[tex] \dfrac{1}{2} = \dfrac{w}{10} [/tex]
=》
[tex]w = 5[/tex]
So, values are :
y = 10w = 5figure 2.
Since, it's an isosceles triangle, w = y,
So, by pythagoras theorem :
=》
[tex] {w}^{2} + {y}^{2} = (7 \sqrt{2} ) {}^{2} [/tex]
=》
[tex] {w}^{2} + {w}^{2} = 98[/tex]
=》
[tex]2 {w}^{2} = 98[/tex]
=》
[tex] {w}^{2} = 49[/tex]
=》
[tex]w = \sqrt{49} [/tex]
=》
[tex]w = 7[/tex]
and we know, w = y, so their values will be equal to 7 units.

A group of students is trying to determine the number of cars that move along a certain section of roadway. The dot plot below shows the speeds of 20 vehicles. Complete the table with the correct values from the dot plot.
Answer:# of cars: 1 | 0 | 0 | 0 | 2 | 4 | 5 | 3 | 0 | 2 | 2 | 1 |
Note: the answers are from left to right in order
Step-by-step explanation:
So this isn't as hard as it seems. You just count the X's and if there is like for example 1 x on 30 then the answer for 30 is 1 since there is only 1 X.
