Answers
Answer:
[tex] \bf \huge ± 5 [/tex]
Step-by-step explanation:
Given :- x^ 2 - 8 = - 33to find :find ''x''explanation :⟼ - x^ 2 - 8 = - 33
step 1 : add 8 to both sides
⟼ − x² − 8 + 8 = − 33 + 8
⟼ - x² = - 25
step 2 : Divide both sides by -1
⟼ - x² / - 1 = - 25 / - 1
⟼ x² = 25
step 3 : take square root
⟼ x² = 25
⟼ x = ± √25
⟼ x = ± 5
∴ x = ± 5.

Use the substitution method to determine the solution of the system of equations. y = -5x and 21x - 7y = 28
Answers
Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
Grace and her brother need $400 to go to band camp. Their parents have agreed
to help them earn money by paying them $25 each time they mow the lawn
and $10 for each hour they babysit their younger brother. They will have to do a
combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and
hours they can babysit, b, to earn $400.
M. 10m + 25b = 400
P.
10m - 25b = 400
R. 25m + 10b = 400
S. 25m - 10b = 400
Answers
Answer:
R. 25m + 10b = 400
Step-by-step explanation:
25m: $25 for time the mow the lawn
10b: $10 for every hour that they babysit their younger brother
400: They need $400 in total
+ : You need to add what they made for mowing the lawn and for babysitting.
Write an equation (any form) for the quadratic graphed below. Y=
Answers
Answer:
y = -2x^2 - 4x - 1
Step-by-step explanation:
We can see that the graph passes through (-2, -1), (-1, 1) and (0, -1).
Let's solve
ax^2 + bx + c = y
a(-2)^2 + b(-2) + c = -1
4a - 2b + c = -1
a(-1)^2 + b(-1) + c = 1
a - b + c = 1
a0^2 + b0 + c = -1
c = -1
we got c = -1 so we input it into the other 2
4a - 2b - 1 = -1
4a - 2b = 0
2a - b = 0
2a = b
a - b - 1 = 1
a - b = 2
a = b + 2
Let's input b = 2a
a = 2a + 2
-a = 2
a = -2
b = 2a = 2*(-2) = -4
c = -1
y = -2x^2 - 4x - 1

Answers
Answer:
Geoffrey incorrectly found the margin of error because he used the wrong sample size.
Please give be brainliest, I really need it.
Geoffrey incorrectly found the margin of error because he used the wrong sample size. Therefore, the correct option is option B.
What is mathematical error?Measurement Error is the difference between the approximated value and the actual value of an object/quantity. The relative error can be computed in the percent with the help of relative error formula. Errors in measuring instruments occur due to inescapable faults in the measuring instrument and limitations of the human eye.
There are three types of errors in solving mathematics problems, which are factual error, procedural error, and computational error. Geoffrey incorrectly found the margin of error because he used the wrong sample size.
Therefore, the correct option is option B.

Distance traveled [tex]d=7km[/tex]
Generally the velocity across a distance is mathematically given given as [tex]V=d/t[/tex]

Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original
Answers
Answer:
La suma de cifras del producto original es igual a 12.
Step-by-step explanation:
De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:
32x=y+54
Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:
y=23x
Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:
32x=23x+54
32x-23x=54
9x=54
x=54/9
x=6
Finalmente, puedes reemplazar el valor de x en y=23x:
y=23x
y=23*6
y=138
Suma de cifras: 1+3+8 = 12

"You purchase a vintage car for $140,000 and it appreciates (i.E. Increases in value) by 4% annually. How much will the car be worth in 10 years?"
Answers
Answer:
Future Value= $207,234.2
Step-by-step explanation:
Giving the following formula:
Initial value (PV)= $140,000
Appreciation rate (r)= 4% = 0.04
Number of years (n)= 10
To calculate the future value of the car after ten years, we need to use the following formula:
FV= PV*(1+i)^n
FV= 140,000*(1.04^10)
FV= $207,234.2
