f(4)=2\cdot4+1=9\\
f(-5)=2\cdot(-5)+1=-9\\
f(0)=2\cdot0+1=1\\
f\left(\dfrac{1}{2}\right)=2\cdot\dfrac{1}{2}+1=2

Write a system of equations in x and y describing the situation. Do not solve the system. Keiko has a total of $ 5600 comma$5600
IgorLugansk [536]

Answer:

The correct answers are x + y = 5600 and x - y = 700.

Step-by-step explanation:

Write a system of equations in x and y describing the situation. Do not solve the system.

Keiko has a total of $ 5600, which she has invested in two accounts.

Let x be the amount of money in the larger account and y be the amount of money in the smaller​ account.

So, Keiko has invested her $5600 in two accounts x and y.

Thus x + y = 5600.

Also, given by the problem, the larger account (x) is $ 700 greater than the smaller account (y).​

Thus x - y = 700.

Thus the two system of equation in x and y describing the given situation are

x + y = 5600 and x - y = 700

First multiply each term by 24(the common denominator found by 8×3) to remove the fractions and make things easier.
24(5) + 24( \frac{x - 2}{3} ) = 24( \frac{x + 3}{8} )
This will give you,
120 + 8(x - 2) = 3(x + 3)
Then just continue to simplify and isolate the variable.
120 + 8x - 16 = 3x + 9
8x + 104 = 3x + 9
5x =  - 95
x =  - 19

What are the three angle measures in the triangle shown below
sergeinik [125]
B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B
