-16 - 7 =
-23
-25 + 9 =
-16
-3 x 8 =
-24
- 6 x -5 =
30
2x + 4 = 14. So, what is the value of x?
x=5
x/3 - 3 = 3. So, what is the value of x?
x=18
7x-2 = 5x + 6 So, what is the value of x?
x=4
3(2x-1) = 21 So, what is the value of x?
x=6
2(2x+3) + 4(2x+1) = 18 So, what is the value of x?
x=2/3
3(2x +4) + 2(3x + 1) = 38 So, what is the value of x?
x=2
If lines are parallel it means …
they have the same gradient
If lines are perpendicular it means…
they cross at a right angle
If the equation of a line is y=3x + 2, what is the gradient of the line?
3
If the equation of a line is y=5x-2, where does it cross the y axis?
-2
What is the y-intercept?
Where a line crosses the y-axis
What is the gradient?
The slope of a line
What is the gradient of this line? y=4
There is no gradient so it will be a horizontal line
Where does this line cross the y-axis? y=2x
It will cross the y-axis at 0
If a line is y= x squared which of these statements is false?
a) the line will be curved
b) the line will have no negative x-co-ordinates
c) the line will have no negative y-co-ordinates
a and c are true, b is false.
Maisie’s has a necklace that is p cm long.
Lottie’s necklace is 3 times Maisie’s.
Sarah has a necklace that is 4 cm longer than Maisie’s
Q. Write expressions for the length of Lottie and Sarah’s necklaces.
Lottie =
Sarah =
Lottie = 3p Sarah = p + 4
Maisie’s has a necklace that is p cm long.
Lottie’s necklace is 3 times Maisie’s.
Sarah has a necklace that is 4 cm longer than Maisie’s
Q. If Maisie’s necklace is 14cm long, what are the lengths of Lottie and Sarah’s necklaces separately?
Lottie = 42 cm Sarah= 18 cm
Maisie’s has a necklace that is p cm long.
Lottie’s necklace is 3 times Maisie’s.
Sarah has a necklace that is 4 cm longer than Maisie’s
Q. If Maisie’s necklace is 14cm long, what is the difference between the lengths of Lottie and Sarah’s necklaces?
42-18 = 24 cm
