Answer:
X=-4
Step-by-step explanation:
No y value so just count ur x value
Dividir cada término por 3
d=h/3 - L
Answer:
see explanation
Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
Answer:
2257 pounds
Step-by-step explanation:
First, get the volume of each and since density is the same, we shall use the density to get the other mass
First volume
Volume=lwh where l is length, w is width and h is height.
Substituting with the given figures
Volume=4*9*168=6048
Density
Density is mass per unit volume
D=m/v
Mass is given as 7900 pounds
Density is 7900/6048=1.3062169312169
Volume of second box
V=2*6*144=1728
Mass is product of volume and density hence 1.3062169312169*1728=2257.1428571428 pounds
Rounded off as 2257 pounds
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...
42 + 37 = 79 Now we need to add the fractions
![\frac{1}{2} + \frac{4}{5} = ... ](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2B%20%20%5Cfrac%7B4%7D%7B5%7D%20%3D%20...%0A)
To add we need a
common denominator. 2 and 5 can both go into 10, so that will be a our common denominator.
Now you have...
which is equal to ![1 \frac{2}{5}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B2%7D%7B5%7D%20)
add that to the 79 we got earlier ...
The toal and final answer is
miles !Hope I helped and remember to vote this as the brainliest answer ! :)
