Y=-×+1 and y=2×+4 how many solutions when graphed

Mathematics
1 answer:
dedylja [7]3 years ago
3 0

Answer:

One solution (-1,2)

Step-by-step explanation:

Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.

To find that solution, we can simply set the equations equal to each other.

y = -x + 1

y = 2x + 4

-x + 1 = 2x + 4

-3 = 3x

-1 = x

Now plug that value back into one of the equations:

y = -x + 1

y = -(-1) + 1

y = 2

So now you know the crossing for these two equations occurs at (-1,2).

Cheers.

Answer: p = 75 + 250

Equation of the situation, in slope-intercept form is given as .

Where,

b = y-intercept

m = slope

n = number of computers sold

p = total cost

All we need to find is the value of m and b.

Using two pairs from the table of values, (4, 550) and (6, 700):

Substitute n = 4, p = 550, and m = 75 in , and find the value of b.

Subtract 300 from each side

b = 250

Substitute m = 75, and b = 250 in

✅Equation that represents the situation would be:

Add: x^5 - 4x^4 + 7x^3 + 8, 9x^3+ 7x^2 - 10, and -2x^5 + 7x^4 - 3x + 8.
Nastasia [14]

Answer:

\large\boxed{-x^5+3x^4+16x^3+7x^2-3x+6}

Step-by-step explanation:

(x^5 - 4x^4 + 7x^3 + 8)+(9x^3+ 7x^2 - 10)+(-2x^5 + 7x^4 - 3x + 8)\\\\=x^5 - 4x^4 + 7x^3 + 8+9x^3+ 7x^2 - 10-2x^5 + 7x^4 - 3x + 8\\\\\text{combine like terms}\\\\=(x^5-2x^5)+(-4x^4+7x^4)+(7x^3+9x^3)+7x^2-3x+(8-10+8)\\\\=-x^5+3x^4+16x^3+7x^2-3x+6

Find the product (4x-3y)(2x+5)
Llana [10]

Answer:

8x²−6xy+20x−15y

Step-by-step explanation:

(4x−3y)(2x+5)

=(4x+−3y)(2x+5)

=(4x)(2x)+(4x)(5)+(−3y)(2x)+(−3y)(5)

=8x²+20x−6xy−15y

=8x²−6xy+20x−15y
