Answer:
90/13, 45/13
Step-by-step explanation:
[tex] - 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\ [/tex]
Simplify:
[tex] - 2 \times 9 = - 18 \\ 7 \times ( - 18) + 9 \times 9 = - 45 \\ - 18 = - 18 \\ - 45 = - 45[/tex]

find the value (s) of the variables (s) in each parallelogram.
Answers
Answer:
y = 4
x = 12
Step-by-step explanation:
Because the lines in the parallelogram are intersecting perpendicularly, each line is equal to the opposite line.
For example,
6y + 1 = 4y + 9
and
2x - 5 = x + 7
So, now we just solve both of those equations.
We'll start with the first one :)
6y + 1 = 4y + 9
6y + 1 - 4y = 4y + 9 = 4y
2y + 1 = 9
2y + 1 - 1 = 9 - 1
2y = 8
y = 4
now onto the second equation :)
2x - 5 = x + 7
2x - 5 - x = x + 7 - x
x - 5 = 7
x - 5 + 5 = 7 + 5
x = 12
How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answers
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution

Which functions have graphs with slopes less than -2?
(Check all that apply.)
Answers
Answer:
Function 2
Step-by-step explanation:
✔️Slope of function 1:
Slope (m) = ∆y/∆x
Using two points on the line, (0, 4) and (1, 9),
Slope (m) = (9 - 4) / (1 - 0)
Slope (m) = 5/1
Slope (m) = 5
✔️Slope of function 2:
Slope (m) = ∆y/∆x
Using the coordinates of any two given pairs form the table, (0, 1) and (1, -3):
Slope (m) = (-3 - 1) / (1 - 0)
Slope (m) = -4/1
Slope (m) = -4
✔️Slope of Function 3:
The function is given in the slope-intercept form, y = mx + b
m = slope
The function y = 2x - 5, therefore has a slope (m) of 2
Slope = 2
✔️Slope of Function 4:
Slope (m) = -1
✅Thus, the functions that has slopes less than -2 are:
Function 2: slope = -4
Function 1, 3, and 4 all have slopes that are greater than -2

El Señor Carlos Villa quién Pide al Banco Azteca un crédito de $110000 sobre una tasa del 10% al año su cantidad a pagar será de
Answers
Responder:
121 000
Explicación paso a paso:
Dado que :
Monto del crédito = 110.000; este es el monto principal, P del préstamo
Tasa de interés = 10% = 10/100 = 0.1
Usando la relación para determinar el monto a pagar al final del año:
A = P (1 + rt)
A = monto final
A = 110 000 (1 + 0,1 * 1)
A = 11 000 (1 + 0,1)
A = 110 000 (1,1)
A = 121 000
La cantidad a pagar al final del año = 121.000
