Integers are every number that is negative, positive, or zero

integers DO NOT include anything more, so no decimals

examples would be

how many grains of sand on the beach?
how many jelly beans in the jar? (assuming none of them are cut in half)
how many times did you call someone? (cant do it half a time)
how many people were born today? (don't get into people not counting as 1)
how many people answered this question on brainly?

just that kind of stuff

You have one type of nut that sells for $4.50/lb and another type of nut that sells for $8.80/lb. You would like to have 12.9 lb

butalik [34]

Answer:

The quantity of first nut = x = 2.4 lb

The quantity of second nut = 12.9 - x = 12.9 - 2.4 = 10.5 lb

Step-by-step explanation:

Let amount of first type of nut = x

Amount of second type of nut = 12.9 - x

Total Cost of first type of nut = 4.5 x

Total Cost of second type of nut = 8.8 × (12.9 - x)

Total cost of both type of nut = 8 × 12.9

Total cost = Cost of first type of nut + Cost of second type of nut

8 × 12.9 = 4.5 x + 8.8 × (12.9 - x)

103.2 = 4.5 x + 113.52 - 8.8 x

8.8 x - 4.5 x = 10.32

4.3 x = 10.32

x = 2.4

Therefore the quantity of first nut = x = 2.4 lb

The quantity of second nut = 12.9 - x = 12.9 - 2.4 = 10.5 lb

The equation of line t is y = -2x + 9. Perpendicular to line t is line u, which passes through

Archy [21]

Answer:

Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$

Step-by-step explanation:

Equation of line t : y = -2x + 9.

We need to find equation of line u, which is perpendicular to line t and passes through point (-10,4)

The equation must be in slope-intercept form.

The general equation of slope-intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

If two lines are perpendicular, their slopes are opposite i.e $m=-\frac{1}{m}$

Slope of line t: y=-2x+9 we get m =-2 (Comparing with general form y=mx+b, we get m =-2)

Slope of line u: $\frac{1}{2}$

So, we get Slope of line u: m= $\frac{1}{2}$

Finding y-intercept:

Using slope m= $\frac{1}{2}$ and point(-10,4) we can find y-intercept

$y=mx+b\\4=\frac{1}{2}(-10)+b\\4=-5+b\\b=4+5\\b=9$

Equation of line u:

So, equation of line u, having slope m= $\frac{1}{2}$ and y-intercept b=9, we get:

$y=mx+b\\y=\frac{1}{2}x+9$

So, Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$
