x = 7 or x = -8
Step-by-step explanation:
3|2x + 1| = 45
Divide both sides by 3.
|2x + 1| = 15
Separate into a compound equation.
2x + 1 = 15 or 2x + 1 = -15
2x = 14 or 2x = -16
x = 7 or x = -8

La fábrica Font Magdalena elabora 6 845 magdalenas diarias y, al empaquetarlas por docenas, utiliza 570 bolsas y le sobran 5 magdalenas. En cambio, la fábrica María Magdalena elabora el doble de magdalenas que la otra fábrica y las empaqueta en cajas de dos docenas. Sin hacer cálculos, ¿cuántas magdalenas le sobran a la segunda fábrica?
Answers
Answer:
5 magdalenas
Step-by-step explanation:
Ya que vamos a estimar la cantidad de magdalenas que sobraron en la fábrica de María Magdalena. Debemos razonar como sigue.
Dado que hay el doble de magdalenas producidos en Maria Magdelena en comparación con el número producido en Font Magdelena y los magdalenas de la primera se empaquetan en dos docenas, se deduce que el número de magdalenas que quedan en Maria Magdelena sigue siendo 5 porque el número de magdalenas y el número envasado aumentó exactamente en la misma cantidad.

4) A TV is on sale. The TV has been reduced by 20%. The sale price is £540. What was the
original price of the TV?
Answers
Answer:
675
Step-by-step explanation:
If the price is 20 % off, then we will pay 100-20 = 80 percent of the original price
Let x be the original price
x* 80% = 540
Change to decimal form
x * .80 = 540
Divide each side by .80
.80x / .80 = 540/.80
x =675
The original price is 675
Which of the folllowing is the equation of a line perpendicular to the line y=-10x+1, passing through the point (5,7).
Answers
Answer:
[tex]y=\frac{1}{10}x+6.5[/tex]
Step-by-step explanation:
We know that a perpendicular line is the slopes reciprocol, so we just flip it.
10/1 --> 1/10
y = 1/10x + b
Now we plug in the coordinates to solve for the y-int!
7 = (1/10)5 +b
7 = 1/2 + b
Subtract 1/2 on both sides!
6.5 = b
Reform equation!

Write a rule for the translation.
A. ( x - 1, y + 2 )
B. ( x + 2, y - 1 )
C. ( x - 2, y + 1 )
D. ( x + 1, y - 2 )
Answers
Answer:
Option B. ( x + 2, y - 1 ) is the correct answer.
Step-by-step explanation:
First of all, we have to write the coordinates of vertices of both triangles and then compare the respective vertices to find the rule,
So the vertices are:
A(-4,2) , B(-3,4) and C(-1,1)
A'(-2,1), B'(-1,3) and C'(1,0)
By comparing respective vertices we can observe that
A(-4,2) => (x+2,y-1) => A'(-2,1)
B(-3,4) => (x+2,y-1) => B'(-1,3)
C(-1,1) => (x+2,y-1) => C'(1,0)
Hence,
Option B. ( x + 2, y - 1 ) is the correct answer.

solve 3x + 5 ⩾ x + 17
Answers
Answer:
Step-by-step explanation:
Simplifying
3x + 5 = x + 17
Reorder the terms:
5 + 3x = x + 17
Reorder the terms:
5 + 3x = 17 + x
Solving
5 + 3x = 17 + x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
5 + 3x + -1x = 17 + x + -1x
Combine like terms: 3x + -1x = 2x
5 + 2x = 17 + x + -1x
Combine like terms: x + -1x = 0
5 + 2x = 17 + 0
5 + 2x = 17
Add '-5' to each side of the equation.
5 + -5 + 2x = 17 + -5
Combine like terms: 5 + -5 = 0
0 + 2x = 17 + -5
2x = 17 + -5
Combine like terms: 17 + -5 = 12
2x = 12
Divide each side by '2'.
x = 6
Simplifying
x = 6
Rehman invests his summer earnings of $3050. He invests past of the money at 8%/year, and the rest at 7.5%/year. After 1 year, these investments earn 242$ in simple interest. How much did he invest at each rate?
Answers
Answer:
let he invest x part of earning at the rate of 8%
simple interest = P*T*R/100 = x*1*8/100 = 0.08x
His invest at the rate of 7.5% = 3050 - x
Again simple interest = P*T*R/100 = (3050 - x)*1*7.5/100 = 228.75 - 0.075x
N0w acc0rding to question
0.08x + 228.75 - 0.075x = 242
0.005x= 13.25
x = 2650
rehman invest 2650 at 8% per year
He invest (3050-2650) = 400 0n 7.5% per year

after a baby was born she began to gain weight at a rate of 2lbs pee month. the weight of the baby at birth was 8lbs. write an equation for W in terms of representing weight in pounds of the newborn baby t months after birth
Answers
Answer:
The required function is: [tex]W(t) = 2t+8[/tex]
Step-by-step explanation:
The weight of the baby increases 2lbs per month which means that it is a linear function.
Now given that the initial weight was 8lbs it will remain constant.
Let t be the number of months and as the weight gain is 2 lbs per month, 2t will be the weight gain after t months.
The function can be written as:
[tex]W(t) = 2t+8[/tex]
Hence,
The required function is: [tex]W(t) = 2t+8[/tex]

An airplane is heading due north at 700 kph, and a wind blows at 60 kph in the direction S 45° E. What is the plane’s ground speed?
640.00 kph
658.94 kph
700.00 kph
743.64 kph
Answers
Answer:
the planes ground speed is 658.94 kph
Step-by-step explanation:
The ground speed of the plane with respect to the wind is determined as 658.94 kph.
Ground speed of the planeThe ground speed of the plane is determined from the resultant speed of the plane with respect to the wind.
R² = 700² + 60² - 2(700)(60)cos45
R² = 434,203.03
R = √434,203.03
R = 658.94 kph
Thus, the ground speed of the plane with respect to the wind is determined as 658.94 kph.

Elijah is keeping track of his baby sister’s shoe size at different ages throughout her childhood. Which statements about the relationship between Elijah’s sister’s shoe size and her age are true? Select all that apply.
A. The relationship is a continuous function.
B. The relationship is a discrete function.
C. The domain and range are restricted to positive numbers.
D. The domain and range are restricted to positive integers.
Answers
Answer:
B and D
Step-by-step explanation:
The function is the relation between the sister's shoe size and her age, being age the independent variable x, and the shoe size the dependent variable y.
If we think this through, we'll find out that age is a discrete variable, and shoe size too. Discrete variable refers to those variable that only admit whole numbers, they don't admit decimal numbers. So, in this case, both variables aren't represented by decimal values. So, the relationship is discrete function, punctual data.
Similarly, the function must be restricted to positive integers, because, as we already said, the variable only admit discrete values and we have to add that only should admit positive discrete values, because age cannot be negative, it wouldn't make sense, also shoe size cannot be negative. In this context, negative numbers don't make any sense.
