Someone please help me asap. I’m confused and need help. Complete the table using the function n = 9b + 19
answer: you would just substitute all of the values you see for b into the equation where there's a b
Answer:
55; 64; 73
Step-by-step explanation:
In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19
if b = 4:
n = 9(4) + 19
n = 36 + 19
n = 55
if b = 5:
n = 9(5) + 19
n = 45 + 19
n = 64
if b = 6:
n = 9(6) + 19
n = 54 + 19
n = 73
Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it
if b = 7:
n = 9(7) + 19
n = 63 + 19
n = 82
Work is correct
Try not to overthink it ^-^

Find the lenght of side BC. give your answer to 3 significant figures
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

4x + y ≥ -1
For option (A). (2, 0)
Substituting the points in the given inequalities.
2 > 2 and 8 ≥ -1
Hence, this is incorrect.
For option (B). (0, 2)
Substituting the points in the given inequalities.
2 > 2 and 2 ≥ -1
Hence, this is incorrect.
For option (C). (0, 3)
Substituting the points in the given inequalities.
3 > 2 and 3 ≥ -1
Hence, this is correct.
For option (D). (0, -1)
Substituting the points in the given inequalities.
-1 > 2 and -1 ≥ -1

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?
Answer:
96 miles
Step-by-step explanation:
The distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 miles
The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.
Answer:
44Step-by-step explanation:
If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:
220:5 = 44
Of course you can find them to be sure:
Consecutive even integers increase by 2.
So if 2x is the smallest of them (x is an integer), then the numbers are:
2x, 2x+2, 2x+4, 2x+6, 2x+8
So their sum: 10x+20
10x + 20 = 220 ⇒ 10x = 200 ⇒ 2x = 40
So the numbers are: 40, 42, 44, 46, 48
Answer:
44

Yesterday Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. Today he sold 15 pounds of apples and 17 pounds of bananas for a goal revenue of $76.75. Determine the price of each pound of apples and the price of each pound of bananas
Answer:
Step-by-step explanation:
35 a + 34 b = 163.50 (given)
15 a + 17 b = 76.50 (given) multiply this equation by -2
-30 a - 34 b = -153.00 now add this equation to the first equation t get
5 a = 10.50 solve this for a (apple's price) then sub this value into one of the equations to find banana price, b.
What is m∠PQR?
The PS is line segment. Q is the point between segments PS. QR is another line segment passes through segment PS. The angle PQR is (3x + 5) degree and angle SQR is (x + 3) degree.
Answer: m∠PQR = 134°
Step-by-step explanation:
Given: PS is line segment. Q is the point between segment PS. QR is another line segment passes through segment PS.
That means ∠PQR and ∠SQR are linear pair [Linear pair is a pair of two angles made on one line and their sum is 180°]
⇒ ∠PQR + ∠SQR = 180° (i)
Since, ∠PQR is (3x + 5)° and ∠ SQR is (x + 3)° [given]
Put this in (i), we get
(3x + 5)° + (x + 3)° = 180°
⇒ 3x + 5 + x + 3 = 180
⇒ 4 x + 8 = 180
⇒ 4 x = 180-8
⇒ 4 x = 172
Divide both sides by 4
⇒ x= 43
So, ∠PQR= (3(43) + 5)° = 134°
Hence, m∠PQR = 134°
The measure of m ∠PQR is 134 degrees.
GivenPS is a line segment.
Q is the point between segment PS.
QR is another line segment that passes through segment PS.
Which property of the triangle is used to solve the value of x?The sum of two angles made on one line is equal to 180 degrees.
[tex]\angle \rm PQR + \angle SQR = 180[/tex]
Where the angle QPR is (3x + 5) degree and angle SQR is (x + 3) degree.
Substitute all the values in the equation
[tex]\angle \rm PQR + \angle SQR = 180\\\\(3x+5) + (x+3) =180\\\\3x+5+x+3=180\\\\4x+8=180\\\\4x=180-8\\\\4x=172\\\\x = \dfrac{172}{4}\\\\x =43[/tex]
The value of x is 43 degrees.
Therefore,
The measure of m ∠PQR is;
[tex]\rm m \angle PQR = 3x+5 = 3(43) + 5= 129+5=134[/tex]
Hence, the measure of m ∠PQR is 134 degrees.

Answer:
− 1 < x < 5
Step-by-step explanation:
Solve for x in the following equation:
kx = m + nx
Answer:
x = [tex]\frac{m}{k-n}[/tex]
Step-by-step explanation:
Given
kx = m + nx ( subtract nx from both sides )
kx - nx = m ← factor out x from each term on the left side
x(k - n) = m ← divide both sides by (k - n)
x = [tex]\frac{m}{k-n}[/tex]
Solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]
Given:
kx = m + nx
We are require to make x the subject of the formula.Thus:[tex]kx = m + nx[/tex]
Subtract nx to both sides of the equation[tex]kx - nx = m + nx - nx\\\\kx - nx = m[/tex]
Factor out x on the left side[tex]x(k - n) = m[/tex]
Divide both sides by (k - n)[tex]\frac{x(k - n)}{k - n} = \frac{m}{k - n} \\\\x = \frac{m}{k - n}[/tex]
Therefore, solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]

Step-by-step explanation:
You decide to go to the candy store in the mall. You arrive at the store with $25 and then purchase 3 candy bars. You then buy a giant candy snake for $12.50. When you leave, you have $8.75 left in your wallet. How much did each candy bar cost? Write the equation to represent the scenario. 8.75 - x - 12.50 = 25.00 25.00 - 3x - 12.50 = 8.75 25.00 - 3x - 8.75 = 12.50 25.00x - 12.50 = 8.75
Answer:
The cost of a candy is $1.25Step-by-step explanation:
given the total amount at hand is $25
let the price of candy be x
then the cost of 3 candy will be 3x
the cost of a candy snake is $12.50.
balance at hand after the end of buying $8.75
the total expenses summed up must equal the initial amount at hand which is $25
the expression for the scenario is 3x+12.5+8.75=25
3x+21.25=25
3x=25-21.25
3x=3.75
x=3.75/3
x=$1.25
The cost of a candy is $1.25
