Solve the simultaneous equations<br> 2x+y=5<br> 5x+3y=12
Bezzdna [24]

Answer:

x=3 and y= -1

Step-by-step explanation:

Step 1: Solve2x+y=5 for y:

2x+y=5

2x+y+−2x=5+−2x(Add -2x to both sides)

y=−2x+5

Step 2: Substitute−2x+5foryin5x+3y=12:

5x+3y=12

5x+3(−2x+5)=12

−x+15=12(Simplify both sides of the equation)

−x+15+−15=12+−15(Add -15 to both sides)

(Divide both sides by -1)

x=3

Step 3: Substitute3forxiny=−2x+5:

y=−2x+5

y=(−2)(3)+5

y=−1(Simplify both sides of the equation)

Answer:

x=3 and y=−1

If f(x)= x^2 and g(x) = 4f (x)-1 then which of the following is the value of g (-3)
Sati [7]

Answer:

<h3>27</h3>

Step-by-step explanation:

Given

f(x)= x^2-2 and g(x) = 4f (x)-1

g(x) = 4(x^2-2) - 1

g(x) = 4x²-8-1

g(x) = 4x²-9

Get g(-3):

g(-3) = 4(-3)²-9

g(-3 = 4(9) - 9

g(-3) = 36-9

g(-3) = 27

What's the solution to x^2-11x+19=-5<br> (this is a Quadratic Equation)
Maru [420]

Answer:

8 and 3

Step-by-step explanation:

We first want to add 5 to both sides, making the equation x^2 -11x +24=0, now, we want to use the quadratic formula, which is( -b <u>+</u> sqrt(b^2 -4ac)) /2a  

for equations of the form ax^2 + bx +c, so in our case, a =1, b=  -11, and c=24,

when you plug in the variables, you will get the answers!   :)
