Answer:
No
Step-by-step explanation:
-3 is supposed to be the answer for b so let's substitute -3 for b.
5(-3)+1=16
-15+1≠16
-15+1 is actually equal to -14
if the -3 would have been positive then it would be correct

Answers
Answer:
1. a. 110
because 5 less than 35 is 30 and 5 less than 10 is 5. it would only make sense for 5 less than 110 is 105
7. D. 54
every other number in the equation is one less (8,7,6,5)
and inbetween those the number is multiplied by 3 (2×3=6, 6×3=18) so then 18×3 =54
the middle left. D. 27
every other one is multiplied by 2 (2×2=4, 4×2=8, 8×2=16) but the first one is multiplied by 3. (1×3=3 3×3=9 9×3=27 27×3=81)
11. A.11
it adds 6 every other (17+6=23, 23+6=29)
for every other first one it adds 4. (7+4=11, 11+4=15, 15+4=19)
12. D. 18
for every other it adds 2.(4+2=6, 6+2=8)
for every other second it adds 6. (6+6=12, 12+6=18, 18+6=24)
15. D. 49
for every other it subtracts 6 (67-6=61, 61-6=55, 55-6=49)
the every other second it divides in half. (32÷2=16, 16÷2=8, 8÷2=4)
18. D. 17
for every other it adds 2.(13+2=15, 15+2=17, 17+2=19)
for every other second it subtracts 2. (21-2=19, 19-2=17, 17-2=15)

Answers
Answer:
y=3x+2
Step-by-step explanation:
y=mx+b
We have our m, which is slope, but we need our y intercept, b.
Substitute your slope, x, and y into the formula and solve for b.
5=3(1)+b
5=3+b
-3 -3
2=b
Now we can plug into equation.

For 2 minutes, a satellite traveled at a steady speed. It traveled 380 kilometers around Earth in that time. What was the satellite's speed?
Answers
Answer: The satellites speed was 190 kilometers per minute.
Step-by-step explanation:
The formula for speed is calculated as:
Speed = Distance/Time
where,
Distance = 380 kilometers
Time = 2 minutes
Speed = Distance/Time
Speed = 380km/2min
Speed = 190km/min
The satellites speed was 190 kilometers per minute.
Therefore, the correct answer is C.

Answer:
3x3x3x3
Step-by-step explanation:
1. 4 is the exponent so you would put down (-3) 4 times but, since the -3 is in parentheses it automatically becomes positive.
2. So, instead of writing (-3)x(-3)x(-3)x(-3) or -3x-3x-3x-3 you would write 3x3x3x3.

When looking at graphs, which of the following statements is true about functions? If each vertical line passes through only one point, it is a function. Each vertical line must pass through at least two points to be a function. If there are more than 3 points on the graph it is not a funcion. A function cannot be represented on a graph.
Answers
Answer:
If each vertical line passes through only one point, it is a function.
Step-by-step explanation:
The true statement about functions:
-If each vertical line passes through only one point, it is a function.
What is function?"It is a relation between a set of inputs and a set of possible outputs."
What is vertical line?"Any line parallel to the Y-axis"
What is vertical line test?"It is a method that is used to determine whether a given relation is a function or not.""This test states that, any vertical line in the plane can intersect the graph of a function at most once".For given question,
We need to determine where the given graph represents a function or not.
When we look at graphs,
Using vertical line test,
If any vertical line intersects the graph more than once, then the graph is not a function.
Therefore, the true statement about functions:
-If each vertical line passes through only one point, it is a function.

Find the error and explain what the correct step should be
Answers
Answer:
m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer
Step-by-step explanation:
okay, so you want to get m
because m is divided by 3, to counter it, you multiply both sides by three
-m/3 = -4
-m/3 times 3 =-4 times 3
because 1/3 times 3 =1, and -4 times 3 = -12, you get
-m = -12
then, divide both sides by - (because you want positive m)
and you get m = 12
the error was that the student did not divide by the negative, so in the end, their sign was wrong.

Karen and Wayne need to buy a refrigerator because theirs just broke. Unfortunately,their savings account is depleted, and they will need to borrow money in order to buy a new one. Sears offers them an installment loan at 15% (add-on rate). If the refrigerator at Sears costs $1,500 plus 5% sales tax, and Karen and Wayne plan to pay for the refrigerator for 2 years, what is the monthly payment?
Answers
Answer:
$53.14
Step-by-step explanation:
Add-on-rate = 16%
Cost = $1,578 + Sales tax = 5%(5% of $1578 = $78.90)
Time = 3 years
Total amount borrowed = 1578 + 78.90 = $1656.90
Charges = 16%
So, 16% of 1656.90
= 16/100 * 1656.90
= $265.10
Total amount would be = 1656.90 + 256.10 = $1913
No. of months in 3 years = 36months
∴ Monthly payment = [tex]\frac{1913}{36}[/tex]
= $53.14.

Answers
Answer:
y = 2/5x - 1/5
Step-by-step explanation:
The first step is to find the slope. We can do this by doing y2- y1/x2 - x1, you can name any number 1 or 2 as long as the x and y are right.
-1 - (-3)/-2 - (-7) = 2/5
Now that we know that the slope is 2/5 we can use the formula
y - y1 = m(x - x1)
y + 3 = 2/5(x +7)
y + 3 = 2/5x + 2 4/5
y = 2/5x - 1/5
The length of a rectangle is 3 less than twice the width. The perimeter of the rectangle is 66. Find the length and width of the rectangle.
Answers
Answer:
15.
Step-by-step explanation:
L + L + W + w = 66
L= w+3
W+3 + w+3 + w + w = 66
4xw + 6 = 66
4xw = 66 - 6
4xw = 60
W + W +w +w =60
W= 60/4
W=15
L = 15+3 (=18)
15+15+18+18=66

Step-by-step explanation:
Factor 3 into its prime factors
3 = 3
Note that 3 is a prime number, it only has itself as a factor (that is on top of the trivial factor "1")
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified
The simplified SQRT looks like this:

Julio es un joven muy emprendedor y ha iniciado un negocio de venta de audífonos y cargadores. Este mes, separa la cantidad de dinero, que ha obtenido en sus ventas, en dos partes: gastos y ganancias y se percata que están a razón de 5 es a 3. Del dinero que gasta, ⅗ lo gasta en compra de más mercadería, 10% en servicios de agua, luz e internet, el restante, S/ 150,60 lo gasta en su alimentación. ¿Cuánto ha sido su ganancia en este mes?
Answers
Answer:
Julio ha ganado 90,36 soles en este mes.
Step-by-step explanation:
Tras una lectura cuidadosa del enunciado podemos inferir que por cada 5 soles destinados al gasto hay 3 soles destinados a ganancias. En lo respectivo a los gastos, la razon del componente restante, cuyo valor es de 150,60 soles, es:
[tex]r = 1 - \frac{3}{5}-\frac{1}{10}[/tex]
[tex]r = 1 - \frac{6}{10}-\frac{1}{10}[/tex]
[tex]r = \frac{3}{10}[/tex]
En otras palabras, el componente restante corresponde al 30 % del dinero destinado a gastos. Entonces, el dinero total destinado a gastos es:
[tex]x = \frac{150,60\,soles}{0.3}[/tex]
[tex]x = 502\,soles[/tex]
Sabiendo la razón existente, es decir, 5 soles para gastos por 3 soles para ganancias, obtenemos la ganancia obtenida por Julio en este mes por la siguiente regla de tres simple:
[tex]y = 150,60\,soles \times \frac{3\,soles}{5\,soles}[/tex]
[tex]y = 90,36\,soles[/tex]
Julio ha ganado 90,36 soles en este mes.
