1) To graph y = 2x +3, give 2 different value for x & find its related y value:
for instance if x = 0 , then y = 3
if x = 1, then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.
2) The inverse of y=2x+3
a) Switch the x & y ===> x=2y+3
b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y
c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y
And the inverse function of y = 2x+3 is y= 1/2(x+3)
Step-by-step explanation:
n=30
6x5=30.that is how you solve it
Answer:
The formula for area is length times width.
it's 8m long, and 6m wide. When we multiply it, we get 48m that is for one side of the cube, so we count how many sides there is. There's 6, so we multiply 6 times 48 and the complete surface area for the whole cube is 288m
Answer:
-1
Step-by-step explanation:
The difference between -5 and 3 is 8. We get to 3 in 4 steps. 8÷4=2, so we count two numbers every step. So the second card is -3 and then the third card is -1
Answer:
-9 ; 5
Step-by-step explanation:
Given that:
Coordinate of Point E = - 2
EG = 7
Possible coordinate of G
On the number line, G may be located on either side of E
If G is to the left of E; the coordinate if G is expressed as : (E - EG) = (-2 - 7) = - 9
If G is to the right of E; the coordinate if G is expressed as : (E + EG) = (-2 + 7) = 5
Hence, the possible coordinates of G are :
-9 and 5
