Y=2x-1
y=-3x+14

First you would substitue one of the y's for the other so
2x-1=-3x+14

no you would solve for x...
add one on both sides
2x=-3x+15

now add 3x to both sides which becomes
5x=15

divide 5 on both sides which gives you x=3

now to solve for y plug into any one of the equations(doesn't matter which one) from before 3 for x and solve
y=2(3)-1
y=6-1
y=5

And that is you answer y=5

. Use the process outlined in the lesson to approximate the number 3√10. Use the approximation √10 ≈3162 277 7.
GaryK [48]

Answer:

sequence of five intervals

(1) 3³  < 3^{\sqrt{10} }   < 3^{4}

(2) 3^{3.1}  < 3^{\sqrt{10} }   < 3^{3.2}

(3) 3^{3.16} < 3^{\sqrt{10} }   < 3^{3.17}

(4) 3^{3.162} < 3^{\sqrt{10} }   < 3^{3.163}

(5) 3^{3.1622}  < 3^{\sqrt{10} }   < 3^{3.1623}

Step-by-step explanation:

as per question given data      

√10 ≈ 3.162 277 7    

to find out      

sequence of five intervals

solution      

as we have given that √10 value that is here

√10 ≈ 3.162 277 7           ........................1

so  

when we find 3^{\sqrt{10} }           ................2

put here √10 value in equation number  2  

we get  3^{\sqrt{10} }   that is  32.27    

so    

sequence of five intervals

(1) 3³  < 3^{\sqrt{10} }   < 3^{4}

(2) 3^{3.1}  < 3^{\sqrt{10} }   < 3^{3.2}

(3) 3^{3.16} < 3^{\sqrt{10} }   < 3^{3.17}

(4) 3^{3.162} < 3^{\sqrt{10} }   < 3^{3.163}

(5) 3^{3.1622}  < 3^{\sqrt{10} }   < 3^{3.1623}

A certain number line uses 20 spaces between consecutive integers.
noname [10]

Answer:

Distance between two consecutive tick marks is 0.05 units.

Step-by-step explanation:

We are given the following information in the question:

It is given that there are 20 ticks between two consecutive number.

Let n and n+1 be the consecutive number.

Formula:

Distance between two ticks =

\displaystyle\frac{\text{Difeerence between the numbers}}{\text{Number of ticks}}\\\\= \frac{(n+1)-n}{20} = \frac{1}{20} = 0.05

Thus, distance between two consecutive tick marks is 0.05 units.

4 gallons

If half covers an eighth, then you need half a total if 8 times. So multiply half by 8 and you get 4.
