Answer:

y = -1/3x - 5 1/3

Step-by-step explanation:

Slope Intercept =

y=mx + b

Substitute the Slope

y= -1/3x + b

Substitute x and y from the point into the equation

-6 = -1/3(2) + b

-6 = -2/3 +b

Isolate the b with the addition property of equality

-5 1/3 = b

Substitute all variables

y = -1/3x - 5 1/3

Sean has 3 times as many vegetable plants as Liz and Sejuan combined. Liz has 3 vegetable plants, and Sejuan has 2 vegetable pla

DIA [1.3K]

Let
x------------>Sean vegetable plants
y------------>Liz vegetable plants
z------------>Sejuan vegetable plants

we know that
y=3
z=2
x=3(y+z)--------> 3(3+2)=15

the answer part A) is
Sean has 15 vegetable plants

part B

This is an example of a part-whole problem.----------> true
This is an example of a comparison problem.-------> true
Addition then multiplication can be used to solve the problem.------> true

Answer:

3. C

4. D

Step-by-step explanation:

$x^2+25=0\\x^2=-25\\x=\pm\sqrt{-25}$

Once $\sqrt{-1}=i$

$x=\pm5i$

A quadratic equation has no real roots when the discriminant ( $\Delta$ ) is negative. $\Delta$ .

Let's try all the equations:

(A)

$2x^2-7x-9=0\\\\\Delta=\sqrt{\left(-7\right)^2-4\cdot \:2\left(-9\right)}\\\Delta=\sqrt{\left(-7\right)^2+4\cdot \:2\cdot \:9}\\\Delta=\sqrt{121} \\\Delta=11$
