Answer:

One solution (2.25,1.75)

Step-by-step explanation:

Well first we need to graph the following

$y=3x-5$

$y=-x+4$

So look at the image below.

So looking at the image below we can tell that the system only has one solution (2.25,1.75).

Find the value of x. x√5=x^4

Kaylis [27]

Answer:

x=0, $\sqrt[6]{5}$

Decimal form,

x=0,1.30766048......

Step-by-step explanation:

x $\sqrt{5}$ = $x^{4}$

x $\sqrt{5}$ - $x^{4}$ =0

(take x as a common factor)

x( $\sqrt{5}$ - $x^{3}$ )=0

So,

x=0 and $\sqrt{5}$ - $x^{3}$ =0

for $\sqrt{5$ - $x^{3}$ =0

(add $x^{3}$ for both sides)

$\sqrt{5}$ = $x^{3}$

x= $\sqrt[3]{\sqrt[2]{5} }$ (multiply 3 by 2)

x= $\sqrt[6]{5}$

So,

x=0, $\sqrt[6]{5}$

Manny and Evan were flying paper airplanes. Manny’s airplane flew 36.5 centimeters and Evan’s airplane flew 18 centimeters. How

professor190 [17]

First subtract manny value 36.5 from Evan values 18 which will give u 18.5 cm which then u have to convert. Since 1 cm is about .4, we can multiply 18.5 by .4 to get the answer 7.4 inches

Find the equation of the line passing through the points 1,-5) and (9,11). y = 2x + [?]

Naily [24]

Answer:

y = 2x - 7

Step-by-step explanation:

Looks like we already have the slope of this line: It is 2. Working with the point (1, -5), we have x = 1 and y = -5 and can from this info easily find the y-intercept, b:

y = mx + b becomes

y = 2x + b, which in turn becomes

-5 = 2(1) + b, or

b = -7,

and so the desired equation is y = 2x - 7
