What is the value of y if log <base 5> <index -7> = y?

Dvinal [7]

Answer:

Hence, the value of y is undefined.

Step-by-step explanation

$log_{5} (-7) = \frac{log(-7)}{log(5)}$ from the property, log_a (b) = (log(a))/log(b).

The value log (-7) was not defined. So, the entire log value also not defined.

Hence, the value of y is undefined.

Alina and Asim share Rs 210 in the ratio 2:5. How much money did each of them get?

slavikrds [6]

Answer:

Step-by-step explanation:

Alina=2x---eq(1)

Asim=5x----eq---(2)

So,we get

2x+5x=210

7x=210

x=30

Now,Putting '30' in eq 1 and eq 2

2*30=60

5*30=150

Therefore Alina got 60 Rs while Asim got 150 Rs

Slope: -2/3 y-intercept: -8 find the linear equation

puteri [66]

Answer:

y = - $\frac{2}{3}$ x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - $\frac{2}{3}$ and c = - 8, hence

y = - $\frac{2}{3}$ x - 8 ← linear equation

A coordinate plane with a line passing through (negative 3, 2) and (0, 3)

Arturiano [62]

Let's check

$\\ \sf\longmapsto Slope=m=\dfrac{3-2}{0+3}=\dfrac{1}{3}$

Y intercept is 3✓

Now

let f(x) be y

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=\dfrac{1}{3}x+3=f(x)\checkmark$
