Answer:

$- 10x + 2y = - 28 - - - (a) \\ - 13x + 3y = - 40 - - - (b) \\ 3 \times (a) - 2 \times (b) : \\ - 4x + 0y = - 4 \\ x = 1 \\ ( - 10 \times 1) + 2y = - 28 \\ 2y = - 18 \\ y = -9$

Answer:

-10x +2y = −28 − − − (a)

- 13x + 3y = -40 — — — (6)

3x (a)-2x (b):

- 4x + Oy = −4

x = 1

(-10 x 1) + 2y = -28

2y = -18

y = -9 Y

answer: (1,

(1,-9)

a car reduced its speed in a ratio of 2 to 3 if the final speed was 90 km per hour then what was the original speed.

Licemer1 [7]

Answer:

Orginal Speed is 135

Step-by-step explanation:

The ratio of final speed: original speed is

$\frac{2}{3\\}$

We know that 90 km is it final speed so, we set up a proportion

$\frac{2}{3} =90/x$

$2x=270\\x=135$

Match the reasons with the statements given.

Alja [10]

I believe the matching would be as follows;
1. ABCD is a rhombus -Given
2. Triangle ADB congruent to Triangle CDB- Diagonals of parallelogram make congruent triangles. The two triangles share a diagonal BD as their third side.
3. ∠1=∠2, ∠3=∠4 ; CPCTE
4. DB bisects ∠ABC and ∠ADC - definition of angle bisector

If α and β are the zeroes of the polynomial 6y 2 − 7y + 2, find a quadratic polynomial whose zeroes are 1 α and 1 β .

ollegr [7]

Answer:

$2y^2-7y+6=0$

Step-by-step explanation:

We are given that $\alpha$ and $\beta$ are the zeroes of the polynomial $6y^2-7y+2$

$y^2-\frac{7}{6}y+\frac{1}{3}$

We have to find a quadratic polynomial whose zeroes are $1/\alpha$ and $1/\beta$ .

General quadratic equation

$x^2-(sum\;of\;zeroes)x+ product\;of\;zeroes$

We get

$\alpha+\beta=\frac{7}{6}$

$\alpha \beta=\frac{1}{3}$

$\frac{1}{\alpha}+\frac{1}{\beta}=\frac{\alpha+\beta}{\alpha \beta}$

$\frac{1}{\alpha}+\frac{1}{\beta}=\frac{7/6}{1/3}$

$\frac{1}{\alpha}+\frac{1}{\beta}=\frac{7}{6}\times 3=7/2$

$\frac{1}{\alpha}\times \frac{1}{\beta}=\frac{1}{\alpha \beta}$

$\frac{1}{\alpha}\times \frac{1}{\beta}=\frac{1}{1/3}=3$

Substitute the values

$y^2-(7/2)y+3=0$

$2y^2-7y+6=0$

Hence, the quadratic polynomial whose zeroes are $1/\alpha$ and $1/\beta$ is given by

$2y^2-7y+6=0$

You owe $1,842.66 on a credit card at a 14.5% APR. You pay $250.00 at the beginning of the month and put another $250.00 in a sa

ElenaW [278]

Credit Card: (1842.66 - 250) (.145/12) = $19.24 interest accumulated on credit card balance

Savings: 250(0.04/12) = $0.83 interest earned

Difference = 19.24 - 0.83 = $18.41 net interest owed
