Answer:{x,y}={-1,-4}
Step-by-step explanation:
[2] 8x = 4y + 8
[2] x = y/2 + 1
// Plug this in for variable x in equation [1]
[1] 10•(y /2+1) - 9y = 26
[1] - 4y = 16
// Solve equation [1] for the variable y
[1] 4y = - 16
[1] y = - 4
// By now we know this much :
x = y/2+1
y = -4
// Use the y value to solve for x
x = (/2)(-4)+1 = -1

2.) Consider the quadratic equation 6x^2+11x-10=0
A.) solve it by using zero product property
Step-by-step explanation:
Roots Theorem
[tex]6 {x}^{2} + 11x - 10 = 0[/tex]
Use the AC method,
The roots must multiply to -60 and add up to 11.
Those two numbers are 15 and -4
So we have know
[tex]6 {x}^{2} + 15x - 4x - 10 = 0[/tex]
[tex]3x(2x + 5) - 2(2x + 5)[/tex]
[tex](3x - 2)(2x + 5) = 0[/tex]
Set each binomial equal to zero
[tex]3x - 2 = 0[/tex]
[tex]3x = 2[/tex]
[tex]x = \frac{2}{3} [/tex]
[tex]2x + 5 = 0[/tex]
[tex]2x = - 5[/tex]
[tex]x = - \frac{5}{2} [/tex]

she can code 4/5 of her game in 1 hour at this rate.
[tex]\sf \dfrac{1}{4} \ hour \rightarrow \dfrac{1}{5} \ or \ 0.2 \ of \ her \ game[/tex]
[tex]\sf 1 \ hour \rightarrow \dfrac{\dfrac{1}{5} }{\dfrac{1}{4} } \ or \ \dfrac{0.2}{0.25} \ of \ her \ game[/tex]
[tex]\sf 1 \ hour \rightarrow \dfrac{1}{5} *\dfrac{4}{1} \ \ or \ \ \dfrac{0.2}{0.25} \ of \ her \ game[/tex]
[tex]\sf 1 \ hour \rightarrow \dfrac{4}{5} \ or \ 0.8 \ of \ her \ game[/tex]
Solution:
We know that:
[tex]\frac{Game}{5} = \frac{Hour}{4}[/tex]Let's multiply 4 both sides to see how much Sophia can code in 1 hour.
Multiplying 4 both sides:
[tex]\frac{Game}{5} = \frac{Hour}{4}[/tex][tex]\frac{Game}{5} \times 4 = \frac{Hour}{4} \times 4[/tex]Finding how much Sophia can code in 1 hour.
=> [tex]\frac{Game}{5} \times 4 = \frac{Hour}{4} \times 4[/tex]=> [tex]\frac{4}{5} \ of \ game = \frac{Hour}{4} \times 4 = 1 \ hour[/tex]Thus, Sophia can code 4/5 of her game in 1 hour.

Step-by-step explanation:
A sixth-grade class must raise at least $447 to go on a field trip. The amount of money, m, that each of the 30 students must raise can be found using the inequality below. If all the students contribute an equal amount, how much will each student need to raise for the class to go on the field trip? 1. Summarize the given situation in your own words. (What do you notice?)
Answer:
Each student must raise $14.90
Step-by-step explanation:
This is actually fairly easy to figure out (at least this part) all you do is 447/30 and then you get your 14.9 (14.90)
m = 14.90
30m = 447
A sports medicine doctor is interested in comparing the effectiveness of a new sports drink for adult athletes. The doctor randomly assigns a group of 80 adult athletes into 2 equal groups. One group is given the new sports drink, while the other is given a placebo.
Which type of study is the doctor using?
A. Experiment
B. Observational study
C. Survey
The type of study which is sports medicine doctor is using on the adult athletes for the placebo soft drink is experiment.
What is the type of statistical study?Statistical study is used to obtain the data and examine this data in the way, that its effectiveness can be measured.
There are three main types of statistical study-
A. Experiment-In this type of statistical study, the observer or the researcher see the change in the variable of a study with change in other variable experimentally by providing the necessary conditions. B. Observational study-In the observational study of statistics, the value of the variables are recorded for different associates of the set.C. Survey-In the survey type of study, the data is gathered by directly asking the queries to the people regarding the study.It is given that a sports medicine doctor is interested in comparing the effectiveness of a new sports drink for adult athletes.
For this, the doctor randomly assigns a group of 80 adult athletes into 2 equal groups of 40-40 each.
Now, one group is given the new sports drink, while the other is given a placebo.Here, the medicine doctor is directly giving the sport drink to a set of sample.
By this he will, see the effectiveness of the group which are given placebo drink compare to the other group, which are not given this drink.
Thus, type of study which is sports medicine doctor is using on the adult athletes for the placebo soft drink is experiment.

Despegue desde la Tierra Un cohete despega desde la superficie terrestre con una aceleración constante de 20 m/seg. ¿Qué tan rápi- do irá el cohete 1 minuto después?
Veremos que la velocidad un minuto despues es 1,200 m/s.
¿Como encontrar la velocidad del cohete?
Sabemos que la aceleración del cohete es constante, y es de 20 m/seg^2 (asumimos que el cohete tiene esta aceleración teniendo en cuenta la aceleración gravitatoria, es decir, 20m/seg^2 es la aceleración neta).
a(t) = 20m/seg^2.
Para obtener la velocidad, integramos la cantidad de arriba:
v(t) = (20 m/seg^2)*t + V
Donde V es la velocidad inicial del cohete, que sabemos es igual a cero.
v(t) = (20 m/seg^2)*t.
Con esta ecuación, podemos ver que la velocidad un minuto despues será:
v(60s) = (20 m/seg^2)*60s = 1,200 m/s.

Select all the equations that are NOT equivalent to p – 7 = 22.
p – p – 7 = 22 – p
p – 7 – p = 22 – p
p – 7 + 22 = 22 – 7
p – 7 + 7 = 22 – 22
p – 7 + 7 = 22 + 7
Step-by-step explanation:
p-p-7=22- p
p-7-p = 22 - p

B. It is increased by $50,000.
C. It is decreased by $55,500.
D. It is increased by $55,500.
Answer:
b
Step-by-step explanation:
The immediate effect on the money supply when the Federal Reserve sells $50,000 in Treasury bonds to a bank at 8% interest is that It is decreased by $50,000.
Option A is the correct answer.
We have,
When the Federal Reserve sells Treasury bonds to a bank, it takes money out of the banking system.
The concept used in this scenario is the Open Market Operations (OMO) conducted by the central bank, which in this case is the Federal Reserve.
Open Market Operations refer to the buying and selling of government securities, such as Treasury bonds, by the central bank in the open market.
The bank pays $50,000 to the Federal Reserve to purchase the bonds, and this money is removed from the money supply, leading to a decrease in the overall money supply in the economy.
Thus,
The immediate effect on the money supply is:
A. It is decreased by $50,000.
