75 = 4(2)^x

Mathematics
1 answer:
Valentin [98]3 years ago
3 0

Answer:

4.229

Step-by-step explanation:

75 = 4(2)^x

75/4 = 2^x

Apply ln both sides

ln(75/4) = ln(2^x)

ln(75/4) = x ln(2)

x = ln(75/4) ÷ ln(2)

x = 4.22881869

Given a linear equation in the form y=mx+b, what are the values of the slope and y-intercept of the equation?(1 point) The slope
slamgirl [31]

Answer:

The slope is m, and the y-intercept is b.

Step-by-step explanation:

What ever is attached to the x is the slope. The y-intercept is the b because it has a 0 on the x axis and a number on the y axis.

Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which stat
sdas [7]

Answer:

Among the given statements the one which describes the properties of

Δ ABC and Δ A"B"C" is,

∠C and ∠C" are congruent after both the translation and dilation.

Step-by-step explanation:

Δ ABC is translated by the rule (x +1, y +1) and then dilated by a scale factor of 2 centered at the origin and the new triangle which we get is named as         Δ A"B"C" .

Now, among the given statements the one which describes the properties of

Δ ABC and Δ A"B"C" is,

∠C and ∠C" are congruent after both the translation and dilation.

Help PLZ i’m just trying to finish this without getting any wrong
otez555 [7]

Answer:

The arrangement of the given equation in the slope - intercept form are

1. y = 1x +82  

Step-by-step explanation:

Given:

Let  A ≡ ( x1 , y1 )   ≡ (-12 , 70)

       B ≡ ( x2 , y2 ) ≡ (-4 , 78)

Slope - intercept form :

y=mx+c

Where,

m is the slope of the line.

c is the y-intercept.

When two points are given say ( x1 , y1 )  and ( x2 , y2)  we can remove slope by  

Slope,

m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}

∴ m =\frac{78-70}{-4--12}\\m =\frac{8}{-4+12}\\m =\frac{8}{8}\\ m= 1

Now equation of a line  for a point ( x1 , y1 )  and having slope m is given as,

(y-y_{1})=m(x- x_{1})\\ \textrm{substituting ( x1 , y1 ) and m we get}\\y-70=1(x-(-12))\\y= x+12+70\\y=x+82

Which is in the required form

y = 1x + 82

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
