The sum of a number b and 7.5 is 4.8

1 answer:

8 0

B + 7.5 = 4.8
-7.5 -7.5
-----------------------
b = -2.7

Hope this helps!!!!!

You can also check your answer by doing replacing the number with the variable ( don't just write the anwser just because you know it, since its pre algebra you have to do it algebraically like above)

-2.7 + 7.5 = 4.8

Hope it helps!

Hello, how can I find the slope of 4y+6x=2?

omeli [17]

You solve for y

4y=-6x+2

y=-6/4x+2

y=-2/3x+2

Slope is -2/3, the number in front of x is the slope.

Determine the equation of the line passing through the points <br> (4,-1) and (-2,-4)

jenyasd209 [6]

Answer:

y = 1/2x - 3

Step-by-step explanation:

the slope:

$m=\frac{-4-(-1)}{-2-4} =\frac{-4+1}{-6} =\frac{-3}{-6} =\frac{3}{6} =\frac{1}{2}$

the equation:

with the point (4, -1)

$y-(-1)=\frac{1}{2} (x-4)$

$y+1=\frac{1}{2}x-2$

$y=\frac{1}{2} x-2-1$

$y=\frac{1}{2} x-3$

I hope this help you

Make a conjecture about the next item in the sequence 1, -4, 9, -16

Snezhnost [94]

To get -4 from 1, we must either subtract 5 from 1 or mult. 1 by -4. Unfortunately subtracting 5 from -4 does not result in 9, and mult -4 by -4 does not result in -16. So neither "works" in predicting the next term.

Can you think of any other experiments to do that would help you discover the pattern 1, -4, 9, -16?
