The sum of two polynomials is –yz2 - 322 – 4y + 4. If one of the polynomials is y - 4yz2 - 3, what is the other polynomial? 0 -2
JulsSmile [24]

Answer:

3yz² - 3z² - 5y + 7

Step-by-step explanation:

Sum of two polynomials = –yz² - 3z² – 4y + 4

One of the polynomial = y - 4yz²- 3

Find the other polynomial

The other polynomial = sum of the polynomials - one of the polynomial

= –yz² - 3z² – 4y + 4 - (y - 4yz² - 3)

= –yz² - 3z² – 4y + 4 - y + 4yz² + 3

= -yz² + 4yz² - 3z² - 4y - y + 4 + 3

= 3yz² - 3z² - 5y + 7

A. 0 -2yz?

B. – 4y + 7 01 - 2yz

C. – 3y + 1 0 -5yz² + 3z² – 3y + 1 D. 3yz² - 3z² – 5y + 7

2. What is an equation line that pass-cs through the point (3,-1) and h (4)
joja [24]
Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then  y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b

y=2x-7 is equation


answer is number 4

What is the slope of the line which passes through (−2, 0) and (0, 4)?
avanturin [10]

Answer:

slope = 2

Step-by-step explanation:

Slope of a line given two points can be found using slope formula:

\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}

Given two points (-2, 0) and (0, 4):

x_{1}=-2 \\x_{2}=0\\y_{1}=0\\y_{2}=4

Plug them into the equation:

\frac{(4-0)}{(0--2)}=\frac{4}{2}=2
