Ok so:
4(4x+3) = 19x + 9 - 3x +3
parenthesis first:
4 x 4x = 16x then 4 x 3 = 12
16x + 12 = 19x + 9 - 3x + 3
combine :) :
19x - 3x = 16x then 9 + 3 = 12
16x + 12 = 16x +12
-12 -12
16x = 16x
They are the same equations lol they equal 0.
The measurement of temperature where for example -2 degrees means 2 degrees below freezing and 2 degrees means 2 degrees above freezing.
Answer:
roots
Step-by-step explanation:
A quadratic equation with real or complex coefficients has two solutions, called roots.
Roots are also called x-intercepts or zeros. ... The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Y = x + 1
y = 2x - 1
basically we r going to sub in one y for another
x + 1 = 2x - 1
1 + 1 = 2x - x
2 = x
now we sub 2 in for x in either of the original equations to find y
y = x + 1
y = 2 + 1
y = 3
so ur solution is (2,3)
The answer is C I just took the test
