Simple algebra question

I forgot how to resolve this kind of exersies, can anyone please resolve it with the prosses I just need to remember thanks! Consider the ordered pair (1, 2) and the two equations in two unknowns: M:

Algrebra confusion about what to do with fractions

2x+y=9 find missing values x and y?1)x=-3so I do this 2(-3)+y=9 -6+y=9 y=9/-6 Buthere is the problem the computer won´t allow me to insert fractions.. so what can i do can I simplify this even more?

The graph of the equation x^2/169-y^2/16=1 is a hyperbola.................5 stars best answer

the standard form equation of a hyperbola is x^2/a^2-y^2/b^2=1. PART I : what are the values of a and Bin the given equation? A=------------------------------------… B=--------------------------------

Discrete probability distribution: Basic

Fill in thevalues in the table below to give a legitimate probability distribution for the discrete random variable x , whose possible values are 2 ,3 , 4, 5, and 6. I obviously cannot provide a table

Evaluate the integral using the given substitution

Evaluate the integral using the given substitution? the integral of 12s^3*ds / √(6-s^4)u= 6-s^4-∫12s³ds/√(6-s⁴) We want to get everything in terms of u: Since u = 6-s⁴, we can differentiate both side

Enter the quadratic equation in standard form

Enter the quadratic equation in standard form. Use the caret (^) to enter exponents.For example enter x2 as x^2. 2x^2 - 10 - 3x = (x-2)^2 + 1-2x^2 -10 -3x = x^2 -4x + 4 +1 x^2 + x -15 = 0

How many powers of 2 are between 3 an 33

4: (4,8,16,32)-If I understand your question correctly there are four: 2^2=4 3^2=9 4^2=16 5^2=25 ans: 4

How do I find the range?!?!?!

I have a graph in front of me and it has one point (with a closed dot) at (-4, 2)then it goes down to (5,-4) with an arrow... how do i find the range from that???-The range is the set of y values.If t

T distribution can you help me

Consider a t distribution with12 degrees of freedom. Compute P (-1.30 Consider a t distribution with8 degrees of freedom. Find the value ofc such that P(t > c) = 0.10 (the > has a line under it for

Solve the system using the substitution method.

0.1x + 0.6y = -2.2 0.6x – 0.7y = 4-0.1x + 0.6y = -2.2 0.1x = -2.2 - 0.6y x = -22 - 6y 0.6x – 0.7y = 4 0.6(-22 - 6y) - 0.7y = 4 -13.2 - 3.6y - 0.7y = 4 -4.3y - 13.2 = 4 -4.3y = 13.2 + 4 -4.3y = 17.2

What is 10 x 20%? 10pts

I am not really sure. I got 2? No trolls, thanks.-10x20% =10 x 20/100 reducing it 10 x 2/10 =10 x 1/5 so 10/5 =2 :)-2-It would be 200% or 2
