Answer:
The value for x is -2 and the value for y is -10 .
Step-by-step explanation:
Firstly , let's write the equations
-2x+3=7 ( equation 1 ) 3x+1 =5+y (equation 2 )
solving equation 1 to get the values of x
or , -2x+3=7
or, -2x+3-3 =7-3 (subtracting -3 on both sides )
or , -2x=4
or, -2x/2 = 4/2 (dividing by two on both sides )
or , -x =2
or x = -2
now let's substitute the values of x in the equation 2
3x+1 =5+y (writing second equation as it is )
or, 3x+1-1=5+y-1 (subtracting -1 on both sides )
or , 3x = 4+y
or , 3 × -2 = 4+y (substituting the values of x from equation 1 )
or , -6 = 4 +y
or , -6-4 = 4+y-4 ( subtracting -4 on both sides )
or , -10 = y
Therefore the values of x and y is -2 and -10 respectively .

Answer:
Its 25.2
Step-by-step explanation:
14.4 + 10.8
If friend house is 10.8 miles north and 14.4 miles east of the bank then distance of person's house from bank is 18 miles.
What is pythagoras theorem?Pythagoras theorem says that in a right angled triangle the square of hypotenuse is equal to the sum of squares of base and perpendicular of that triangle.
[tex]H^{2} =B^{2} +P^{2}[/tex] in which P is perpendicular, B is base, H is hypotenuse of triangle.
How to find hypotenuse?When we express person's house,his friend's house and bank on the surface then it will look like a right angled triangle.
H=[tex]\sqrt{B^{2} +P^{2}}[/tex]
=[tex]\sqrt{10.8^{2} +14.4^{2} }[/tex]
=[tex]\sqrt{324}[/tex]
=18 miles
Hence the distance of person's house from bank is 18 miles.

Answer:
f(x)= x^2 - 2, the one in red.
Step-by-step explanation:
To move a quadratic function up/down, you change the value at the very end of the formula.
So instead of f(x)= x^2 + 1, you would do f(x)= x^2 - 2, to move it down 3. This would be the one in red.
I REALLY NEED HELP PLS
Answer:
Step-by-step explanation:
100+2x+40=180(sum of interior angle of a triangle)
140+2x=180
2x=180-140
2x=40
x=40/2
x=20
Answer:
x=20
Step-by-step explanation:
the sum of the angles of a triangle is 180
so it means,
100+40+(2×)=180
140+(2×)=180
2×=180-140
2×=40
divide both sides by 2
x=20
to prove this substitute 20 inside see if the result is 180
40+100+(2×)=180
×=20
40+100+(2 (20))=180
140+40=180
140+40=180
Good luck.

Step-by-step explanation:
La promoción de 5to grado de secundaria "Jóvenes caminando hacia el éxito" han estado realizando actividades
para su viaje y fiesta de promoción, logrando hasta la fecha juntar la suma de S/. 24 000. Por ello, el comité de
padres de familia convocó una reunión general para decidir dónde depositar el dinero, presentando dos opciones
de ahorro:
Opción 1: Depósito por 2 años que paga el 10% trimestral en interés simple.
Opción 2: Depósito por 2 años en una cuenta que paga el 18% de semestral compuesto anual.
Ayuda a los padres de familia de la promoción a elegir la mejor opción.

Answer:
Los padres de la promoción deben elegir la Opción 1, porque da un mayor interés en la inversión.
Step-by-step explanation:
El monto recaudado por la escuela secundaria = S / 24,000
Las opciones que tienen los padres para depositar el dinero son;
Opción 1:
El interés simple del depósito = 10%
El número de veces que se aplica el interés anualmente = Trimestral
El número de años para el depósito = 2 años
opcion 2
La tasa de interés del depósito, r = 18% de interés simple.
El número de veces que se aplica el interés = Semestralmente
La cantidad de años que se ahorrará la cantidad = 2 años
Opción 1
Observamos que para el interés simple no hay interés ganado sobre el interés anterior.
Por lo tanto;
Una inversión que paga el 10% trimestralmente = (1/4) año pagará 4 × 10% = 40% en 4 × (1/4) año = 1 año
La cantidad de interés ganado en 2 años invirtiendo en la opción 1 se da como sigue;
Yo = P × R × T / (100)
∴ I₁ = 24.000 × 40 × 2/100 = 19.200
El interés después de 2 años en la opción 1, I₁ = S /. 19.200
opcion 2
Una inversión que paga 18% semestralmente = (1/2) año pagará 2 × 18% = 36% en 2 × (1/2) año = 1 año
La cantidad de interés ganado en 2 años invirtiendo en la opción 2 se da a continuación;
Yo = P × R × T / (100)
∴ I₂ = 24.000 × 36 × 2/100 = 17.280
El interés después de 2 años en la opción 2, I₂ = S /. 17.280
Dado que el interés dado por la opción 1, I₁ = S / .19,200 es mayor que el interés dado por la opción 2, I₂ = S /. 17.280, los padres de la promoción deben elegir la opción 1, que es depositar durante 2 años que paga un interés simple trimestral del 10%

Answer:
The area is about 25/2 inches^2
Step-by-step explanation:
You are given an isoceles triangle; the sides equal to each other are radiuses of the circle G. They are both 5 inches in length.
The angle between the two equal sides is equal to 88 degrees.
To find the height of the triangle, draw a line perpendicular to GH and solve for the lengths of the sides.
sin(88) = x/5
5sin88 is about 5 it is (4.99695)
Multiply the side length GH (5) and the solved height and divide by two;
The area is about 25/2 inches^2

Ali bought his mom 2 dozen (24) of roses. 1/3 of them are red and the rest are pink. How many are pink
Answer:
there are 16 pink roses
Step-by-step explanation:
Number of pink roses = fraction of pink roses x total number of roses bought
fraction of pink roses = 1 - fraction of red roses
1 - 1/3
= 3/3 - 1/3 = 2/3
Number of pink roses = 2/3 x 24 = 16
