twice a number plus another number is 310. The difference between the two numbers is 55. What are the two numbers
Masteriza [31]
T us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
   = 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
   = 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3

(x+5)(x-3)=y<br> How do I get y to equal 0
trasher [3.6K]

Answer:

x=-5 or x=3

Step-by-step explanation:

when multiplying anything by 0, the answer will be zero

In this case, one of the two factors has to be equal to 0

start by splitting into

(x+5) = 0

solve the equation

subtract 5 from both sides

x = -5

now, repeat for the other binomial

x-3 = 0

add 3 to both sides

x=3

storchak [24]
Take y=3 and plug it into y=-3x+6. This gives you 3=-3x+6. Solve for x, you get x=1. Now plug 1 into y=-3x+6 and you get 3. Answer is (1,3)

Use synthetic division to divide (x^3 +12x^2 +48x +26) / (x+4)
deff fn [24]

Answer:

The correct option is C

Step-by-step explanation:

(x^3 +12x^2 +38x +26) / (x+4)

Use the coefficients of dividend.

And the divisor is -4:

Bring down 1 and  multiply it by -4 and add to 12

12-4 = 8

Now multiply 8 by -4 = -32

48-32 = 6

Now multiply 6 by -4 = -24

26-24= R2

                        1     12    38    26

                              -4    -32    -24

                       _______________

                        1      8     6      R2

Thus the correct option is C ....
