Find two numbers, if … c Their sum is 3/5 and their difference is 7 1/5

Mathematics
1 answer:
Makovka662 [10]3 years ago
7 0

Answer:

39/10 and - 33/10.

Step-by-step explanation:

7 1/5 = 36/5  so if the 2 numbers are x and y, we have:

x + y = 3/5

x -  y =  36/5      

Adding the 2 equations to eliminate y:

2x =  39/5

x = 39/10.

So 39/10 + y = 3/5  (from the first equation).

y = 3/5 - 39/10

y = 6/10 - 39/10

y = -33/10.

Write the polynomial in standard form and identify the x-intercept, as well as the zeros for
likoan [24]
Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form

f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9

(-4,1) and (-8,7) <br><br> write an equation in slope-intercept form
Alchen [17]

Answer:

y = -2x - 9

Step-by-step explanation:

so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.

-1 = -2(-4) + b

multiply -2 and -4

-1 = 8 + b

we subtract 8 from itself and -1

-9 = b

Our equation is y = -2x - 9

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors
zhuklara [117]
<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3),   (1,4),   (1,5),   (1,6)

(2,3),  (2,4),  (2,5),  (2,6)

(3,3),  (3,4),   (3,5),  (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

0.17*3,240= 550.8

550 students will be accepted

we have to round down as only 17% can be accepted and u cant have 0.8th of a person
