lg7^x^2 = lg9^x
Bring the power forward.
x^2lg7 = xlg9
x^2/x = lg9/lg7
x = lg9/lg7 = 1.13

Write an equation of a line that has a slope of -2 and passes through the point (1,4)
RoseWind [281]

Answer:

y = -2x + 6

Step-by-step explanation:

Since we already have the slope we just need to find the y-intercept.

To do that just plug in the point you were given. (1,4)

4 = -2(1) + b (b represents the y-intercept)

4 = -2 + b (add 2 on both sides)

6 = b

y = -2x + 6 is the equation

Hope this helps!!

Two percent of Jennies skin cells were burned when she escaped from a fire. If 
andreev551 [17]

1.813*10^{12} cells of Jennies skin were not burned.

Step-by-step explanation:

Given,

Burned skin cells = 3.7*10^{10}

This represents 2% of total skin cells.

Let,

x represents the total number of skin cells.

2% of x = 3.7*10^{10}

\frac{2}{100}x=3.7*10^{10}\\\\0.02x=3.7*10^{10}

Dividing both sides by 0.02

\frac{0.02x}{0.02}=\frac{3.7*10^{10}}{0.02}\\\\x=1.85*10^{12}

Number of not burned cells = Total - burned

Number of not burned cells = 1.85*10^{12}-3.7*10^{10}

Number of not burned cells = 1.813*10^{12}

1.813*10^{12} cells of Jennies skin were not burned.
