Answer:

I think it's 3

Step-by-step explanation:

To calculate the gradient equals to

y(1)-y(2)

-----------

x(1)-x(2)

So - 5 - 1 = - 6

6 - 2 = 4

-6 - 3

--- = ----- x

4 2

And the first y intercept is 1 so I guess it's 3.

Just for refernece, not sure if I'm correct. Sry

Is 69/100 and 6/10 equivalent fractions

zubka84 [21]

No. If you divide 69 by 100 you would get 0.69. If you divided 6 by 10 you would get 0.6. Therefore 69/100 and 6/10 is not equivalent.

Armando and Bianca are 290 feet apart when they start walking toward one another. Bianca walks twice as fast as

aivan3 [116]

9514 1404 393

Answer:

d = 290 -3x

Step-by-step explanation:

For each x feet that Armondo travels toward Bianca, Bianca travels 2x feet toward Armondo. The net effect is that the distance between them decreases by x+2x = 3x feet. The distance starts at 290 feet when x=0, so the distance can be described by ...

d = 290 -3x

Write an equation, in point-slope form, for the line that goes through points (4,4) and (-4,-1).

Soloha48 [4]

Answer:

C.) Y= 5/8x + 1 1/2

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (4,4) and (-4,-1). After, substitute the slope and a point into the point slope form.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{4--1}{4--4}= \frac{5}{8}$
