How many variable terms are in the expression 3x to the third power Y plus 5X to the second power plus Y +9

They are variable in an equation. so if you have (3x^3)+(5X^2)+Y+9 then your variables are x X and Y (im assuming the capital X is there and not a typo) if that was a typo and meant to be lowercase, then its just a 2 variable with the x and y

Find an equation in slope intercept form of the line that has a slope of -8 and passes through point A (1,5)
ollegr [7]

Answer:

8x+y-13=0

Step-by-step explanation:

let the given point be

A(1,5)=(x1,y1)

slope(m)= -8

then,equation of straight line is,

(y-y1)=m(x-x1)

(y-5)= -8(x-1)

y-5= -8x+8

8x+y-5-8=0

therefore,8x+y-13=0 ..........(i) is the required equation.

oksian1 [2.3K]

Answer:

-\frac{3}{4}  meters

Step-by-step explanation:

From the answer choices, we basically need to find which of them is between   -\frac{1}{2}  and  -1\frac{2}{3}

<em>Converting all of them to decimals would make it really easier:</em>

<em />

<em>So we need to find number between -0.5  and -1.67</em>

<em />

<em>Answer choice A is -2.33</em>

<em>Answer choice B is  -0.75</em>

<em>Answer choice C is  -0.25</em>

<em>Answer chioce D is  -1.83</em>

<em />

<em>So which number, from the choices, is between -0.5 & -1.67?</em>

Clearly, it is -0.75, or,  -\frac{3}{4}  meters
