Answer:
1. 15
2. 45
3. There is a missing digit.
Step-by-step explanation:
Given: <u>y=3</u> and <u>x= 1/2</u>
<h2>Question 1: 4(2y-4x)-1=</h2>- Numerical factors in this term have been multiplied.
4(6-4/2)-1
- We can reduce this fraction by dividing both numerator and denominator by a common numeric factors.
4(6-2)-1
- Numerical terms in this expression have been added.
4*4-1
- Numerical factors in this term have been multiplied.
16-1
- Numerical terms in this expression have been added.
15
<h2>Question 2: 4x^2+2y^3-10 = </h2>4/2²2*27-10
4/2²+54-10
- We need to perform a multiplication.
- The following rule is applied:
45: Numerical factors in this term have been multiplied.

Answer:
y =
Step-by-step explanation:
with the point slope form, plug -9 (x coordinate) into x1, -3 (y coordinate) into y2, and -4/3 (slope) into m
y - y2 = m(x - x1)
y - (-3) = -4/3 (x - (-9))
y + 3 = -4/3 (x + 9)
y + 3 = -4/3 x + -12
y = -4/3 x - 12 - 3
y =
