Answer:
3 hours
Step-by-step explanation:
Let Tamar did the job for x hours,
Since, her charges for 1 hour = $ 8,
⇒ Her charge for x hours = 8x,
Also, the bus fare = $ 6,
hence, her total charge = Bus fare + Her charges for x hours
= 6 + 8x,
If the total charge is at least $30,
⇒ 6 + 8x ≥ 30
⇒ 8x ≥ 24
⇒ x ≥ 3
Thus, the minimum number of hours for a babysitting job she would accept = 3 hours

Select the interval where g is negative.
PLSSS HELLPPP!!!
The interval where g is negative is in the domain of -5 ≤ x < 1
The reason for the above selected interval is as follows;
A function is negative over an interval where the graph of the function is
below the x-axis, and the y-coordinate values are negative, excluding
where the y-value is zero. The interval over which a function is negative is
also called the negative region
From the given graph, the function, g(x), we have;
At x = 1, y = g(x) = 0
At x = -5, y = g(x) ≈ -7 and increasing to 0
Therefore at x = -5, g(x) ≈ -7, is negative
Tis negative over the interval -5 ≤ x < 1
Therefore;
The interval where g(x) is negative is -5 ≤ x < 1.

(2a+1) - 4a(2a+1)+4a
Answer:
2a (3-4a)
Step-by-step explanation:
(2a+1)-4a(2a+1)+4a
2a+1-8a²-1+4a
= 2a+4a-8a²
=6a-8a²
= 2a(3-4a)
Answer:
Step-by-step explanation:
Use distributive property: a*(b+c) = (a*b) + (a*c)
-4a*(2a + 1) = -4a*2a + 1*(-4a)
= -8a² - 4a
2a + 1 - 4a(2a + 1) + 4a = 2a + 1 - 8a² - 4a + 4a
= 2a + 1 - 8a²

Un capital de S/. 42.000 colocado a una tasa de interés del 7% capitalizable anualmente, ¿en cuántos meses produce un interés de S/. 8 700?
Answer:
Se requiere 34 meses para producir un interés de 8700 soles.
Step-by-step explanation:
Asumamos que el capital aumenta conforme a una tasa de interés compuesto, cuya fórmula se describe aquí abajo:
[tex]C = C_{o}\cdot \left(1 + \frac{r}{100} \right)^{t}[/tex] (1)
Donde:
[tex]C_{o}[/tex] - Capital inicial, en soles.
[tex]C[/tex] - Capital actual, en soles.
[tex]r[/tex] - Tasa de interés mensual, en [tex]\frac{1}{a}[/tex].
[tex]t[/tex] - Período de capitalización, en años.
Si sabemos que [tex]C_{o} = 42000[/tex], [tex]C = 50700[/tex] y [tex]r = 7\,\frac{\%}{a}[/tex], entonces el período de capitalización es:
[tex]C = C_{o}\cdot \left(1 + \frac{r}{100} \right)^{t}[/tex]
[tex]\frac{C}{C_{o}} = \left(1 + \frac{r}{100}\right)^{t}[/tex]
[tex]\ln \frac{C}{C_{o}} = t\cdot \ln \left(1 + \frac{r}{100}\right)[/tex]
[tex]t = \frac{\ln C - \ln C_{o}}{\ln \left(1+\frac{r}{100} \right)}[/tex]
[tex]t = \frac{\ln 50700 - \ln 42000}{\ln \left(1+\frac{7}{100} \right)}[/tex]
[tex]t = 2.782\,yr[/tex]
Es decir, se requiere 34 meses para producir un interés de 8700 soles.

mary selects a piece of candy at random form a jar that contains four peopermint, five cherry, three butterscotch, and two lemon candies. what is the probability that the candy she selects is not lemon?
Answer:
6/7 or 85.7 percent
Step-by-step explanation:
First, you will want to add all of the candies together and find the sum
Then you will want to take away the Lemon candies as you are looking for the probability of NOT choosing those,
so at this point, you should have 12 take that 12, and put it over the total number, so 12/14 then either simplify, or switch to a percentage, or both, and there is your answer.

Answer:
x=-4/9, y=-74/9.
Step-by-step explanation:
y=32x+6
y=14x-2

Answer:
W = 55°X = 125°Y = 110°Z = 70°Step-by-step explanation:
Corresponding angles in similar figures are congruent. Corresponding angles are listed in the same order in the similarity statement.
∠A = ∠W = 55°
∠B = ∠X = 125°
∠C = ∠Y = 110°
∠D = ∠Z = 70°
Question from Venn diagram solving... plz solve. Worth 15 points
Answer:
For this type of problem, it is best to use Venn diagrams as shown in the picture. The areas where the circles intersect are the mutual events that occur together. The area where all circles intersect is denoted as x. These are the students who play all sports. Assuming all of the students play sports in the school, all of the numbers in the circles should add up to 405. The remaining area would be the difference. The solution is as follows:
Students who play tennis and hockey: 45 - x
Students who play hockey and softball: 60 - x
Students who play only tennis and softball: 39 - x
Students who only play tennis:
251 - 45 + x - 39 +x -x = x + 167
Students who only play hockey:
157 - x - 45 + x - 60 + x = x + 52
Students who only play softball:
111 - x - 60 + x - 39 + x = x + 12
The sum of all of these should be 405:
45-x+60-x+39-x+x+167+x+52+x+12 = 405
Solving for x,
x = 30
Therefore, there are 30 pupils who play all sports; 15 pupils who play tennis and hockey; 30 pupils who play hockey and softball; 9 pupils who play tennis and softball; 197 pupil who only play tennis; 82 pupils who only play hockey; and 42 pupils who only play softball.
Step-by-step explanation:
Hope this is correct, if it is wrong then please feel free to critique me and I wil correct my mistake(s). I'm sorry in advance if it is incorrect.

[tex]3x-3\le \:-\frac{11}{2}+\frac{1}{2}x[/tex]

[tex]x\le \:-1[/tex]
x = -1
3(-2) ≤ ½(0) - 6

-6 ≤ -6
This is true.
x = -2
3(-3) ≤ ½(-1) - 6

-9 ≤ [tex]-\frac{13}{2}[/tex]
This is also true.
Therefore, x ≤ -1.

What transformation has taken place on the coordinate grid pleaseee help my final! I'll give rate and heart etc
Answer:
Translation across the coordinate plane
Step-by-step explanation:
Here, we want to get the kind of transformation that has occurred to the shape
from the given coordinate diagram, we can see that A shifted from (2,3) to (-3,6)
B shifted from (2,-2) to (-3,1)
and C shifted from (-1,-4) to (-6,-1)
If we look at these, we can observe that there is a change in the x-axis coordinate in each by (-1-(-6) or 2-(-3) = 5 units
and there is a change in the y-axis value by (3-6) = -3 units
so the transformation here can be represented generally as;
(x -5, y+ 3)
With this, we can see that what we have represented is simply a translation across the coordinate plane
