Step-by-step explanation:
3 is in the hundred millions
<h3>
Answer: B. (10, -20)</h3>
Apply substitution
y = -5x + 30
y = -5*10 + 30 ... replace x with 10, since x = 10 is given
y = -50 + 30
y = -20
So x = 10 and y = -20 pair up to form the solution of the system.
Answer:
a) None
b) (0, -2)
Step-by-step explanation:
The x-intercept is the point at which the line cuts through the x-axis, while the y-intercept in the point at which the line cuts through the y-axis.
a) The line does not cut through the x-axis, thus it has no x-intercept.
b) The line cuts through the y-axis at y= -2, making its y-intercept (0, -2).
A is really worth one.
So it’s a + 3a = 4a
4a=16 is the equation now, so now you have to get rid of the 4 by dividing 4 on both sides.
4a = 16
—— = ——
4 4
The 4 is gone so now you get a=4
