Answer:

a then b each have a value work out whether its numbered or distributed on a number line -2 , -1 0 , 1, 2, 3, 4, 5 etc if a is -4 then if 1-a = 1--4 the answer is -5 then when the question ab +1 comes up if b = 3 then ab-1 will be written out again as -4 x 3 -1 = -12-1=-13 etc. etc.

ab+1 is different if a = -4 and b = 3 then ab+1 = -4 x 3 +1 = -12 +1 = -11

its count back for( minus then times) count back for( minus then subtract ) and count back for any subtract and forward for positive add minus

Hope that helps branliest please =)

Answer: 1 1/2

Step-by-step explanation:

First subtract 1 1/3 from 3 1/3 to find what is left over from her first batch of browns, 2. Then subtract 1 1/3 from 2 and get 2/3. 2/3 is 1/2 of 1 1/3, so she can make 1 1/2 more batches of brownies.

Graph the following lines and using the graph determine several values of x for which the graph is positive (negative): y=−4x+3

True [87]

Answer:

Step-by-step explanation:

Given line is,

y=-4x+3

when, x=-1 , y=-4(-1)+3=4+3=7

when, x=0 , y=-4(0)+3=0+3=3

when, x=1 , y=-4(1)+3=-4+3=-1

So, we got the points (-1,7) , (0,3) , (1,-1)

Now, putting the points in the graph and adding them , we will get the graph of given line.

Please check image for the graph.

Now for the second part-

The graph is positive means- it will be above the x-axis, that is y value will be positive.

From the graph we can see that, if x<0 , then y is positive.

So, any value of x which is less than 0 , will give the positive graph here.

Solve the equation 4s2+32s=60 by completing the square

lord [1]

Answer:

s = -4 ± √31

Step-by-step explanation:

Given 4 $s^{2}$ + 32s = 60

divide by 4 throughout

$s^{2} + 8s = 15\\s^{2} + 8s + (\frac{8}{2}) ^{2} = 15 + (\frac{8}{2}) ^{2}$

$(s + 4)^{2} = 31\\s + 4 = \sqrt{31}$

s = -4 ± √31
