Y = -3x +10 3x +y = 5 substitution method

Mathematics

Answer:

no solutions

Step-by-step explanation:

y = -3x +10

3x +y = 5

Substitute the first equation into the second equation

Let every instance of y in the second equation be replaced with -3x+10

3x+ (-3x+10) = 5

Combine like terms

10 =5

This is never true so there are no solutions

(These are parallel lines with the same slope but different y intercepts)

Could someone please explain! I cant figure it out.

2^-2 = 1/2^2

so: (1/2^2)*(12*3)-5^3

simplify: (1/4)*36-125

36*(1/4) = 36/4 so: 9-125

subtract: -116

Answer: About (-2.414, 0) and (0.414, 0)

Step-by-step explanation:

Let us graph the equation given and see what the x-intercepts are. These are points where the line intercepts the x-axis. <em>See attached</em>.

This means our x-intercepts are at about (-2.414, 0) and (0.414, 0).

These are also equal to $-1-\sqrt{2}$ and $-1+\sqrt{2}$

X=4<br> what is the domain and what is the range and is it a function?

marusya05 [52]

The domain is the numbers you can use for x

so the domain is 4

the range is the possible y values we get from that domain
we get all real numbers because it goes up and down infinitey

domain is 4
range is all real numbers

Make a proportion:

4/25 = x/120

cross multiply

480 = 25x

Divide both sides by 25

X= 19.2
