Answer:
This system of equations has infinite points of intersection
Step-by-step explanation:
* To know the point of intersection of the system of equations,
you will solve the graphically or algebraically
- Graphically by drawing two lines on the coordinate plane
- Algebraically by substitution method or elimination method
* Lets use the substitution method
∵ y = 4 - x
∵ 2y = 8 - 2x
- Substitute y in the second equation by its value in the
first equation
∴ 2(4 - x) = 8 - 2x ⇒ open the bracket
∴ 8 - 2x = 8 - 2x
* The two sides equal each other, that means we can use any
vales of x, and on the graph they will be the same line for
the two equations
∴ This system of equations has infinite points of intersection
Answer:
24 mm
Step-by-step explanation:
Since it is a right triangle, we can use Pythagorean theorem
where a and b are the legs, and c is the hypotenuse.
We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.
Solve the exponents
Now, solve for b. To do this, get b by itself.
First, subtract 100 from both sides
Take the square root of both sides
b=24
So, the other leg is 24 mm
Answer:
The key is finding a common # on the bottom (aka: a common 'denominator')
once you do this, you can easily add and subtract them!
Step-by-step explanation:
EX:
1/2 + 2/3 = ?
<u>*EASIEST TRICK!!*</u>
take your 2nd denominator: (3) and multiply it by the entire (1st fraction): 1/2
<em>(when we MULTIPLY fractions, it is easy as pie, we can just multiply across the top and across the bottom) in this case, we will multiply both top and bottom by the 2nd denominator (3)</em>
(1 x 3)/(2 x 3) = 3/6 <em>(3/6 is another way of saying 1/2, so we're good!)</em>
now take the 1st denominator (2), and multiply the entire 2nd fraction by that:
(2 x 2)/(3 x 2) = 4/6
<em>now we have 6 on the bottom of both! time for the magic:</em>
3/6 + 4/6 = 7/6
but wait! (that means we have 7 slices of a 6-piece pie! ...so we <em>actually </em>have, 1 full (6-piece pie) and 1 slice leftover! <em>(awww yeeea)</em>
<em>so, 7/6</em><em> --> </em><em>1 </em><em>(full pie) </em><em>1/6 </em><em>(leftover!)</em>
<u><em>now to put it all back together:</em></u>
1/2 + 2/3 = 1 & 1/6
