Answer:
see explanation
Step-by-step explanation:
To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation
(- 1, - 1)
x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation
(2, 11)
x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation
(4, 7)
x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation
(7, 1)
x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation
Where’s your previous question at?
Answer:
x = -5, x = 1.5
Step-by-step explanation:
If the two expressions multiplied together is 0, that means that one of the expressions would have to equal 0. This gives us two possible answers. Our two equations are now:
x + 5 = 0
2x - 3 = 0
We will first solve the first one!
To isolate x, we subtract 5 from both sides to get:
x = -5
Onto the second one!
We begin to isolate x by adding 3 to both sides.
2x = 3
Now we divide both sides by 2.
x = 3/2 or 1.5
Answer:
x = 4
Step-by-step explanation:
The given equation is as follows :
4(3x - 6) = 24
If we want to solve the above equation, the steps are:
Using distributive property first as:
4(3x)-4(6)=24
12x-24=24
Adding 24 both sides,
12x-24+24=24+24
12x=48
x=4
So, the value of x = 4. All given steps are correct.
Find two factors of the last number that add up to the middle number.
a) two factors of 16 that add to 10: 8 and 2. Because 8x2=16 and 8+2=10. then do this:
(x+8)(x+2)
b) (x+4)(x+3)
c) (x+12)(x+1)
