Answer:

x = 4, y = -10

Step-by-step explanation:

if both expressions equal 'y' then you can solve by setting them equal to each other:

-5x + 10 = -2x - 2

-3x + 10 = -2

-3x = -12

x = 4

find 'y':

y = -5(4)+10

y = -20 + 10

y = -10

use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following equation. y=x^2+x+6

stepladder [879]

Answer:

(-1/2, 23/4)

Step-by-step explanation:

Vertex of graph: -b/2a

b=1

a=1

Therefore, -1/2 is your x-value

Solve for y: y=1/4-1/2+6

y=5 3/4 or 23/4

Therefore your vertex is: (-1/2, 23/4)

What is the sum of 2 3/4 and −2 3/4 ?

makvit [3.9K]

Answer:

2 $\frac{3}{4}$ + -2 $\frac{3}{4}$ = 0

Step-by-step explanation:

1st step convert into improper fraction:

===> 2 $\frac{3}{4}$ + -2 $\frac{3}{4}$

===> $\frac{16}{4}$ + $-\frac{16}{4}$

2nd step now adding the numbers:

( Plus sign and minus sign multiplies and hence the plus sign changes to minus)

===> $\frac{16-16}{4}$

Therefore the sum of 2 $\frac{3}{4}$ + -2 $\frac{3}{4}$ = 0
