Answer:
x = 4
Step-by-step explanation:
y = - 2 is the equation of a horizontal line parallel to the x- axis.
A perpendicular line is therefore a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, - 2 ) with x- coordinate 4 , thus
x = 4 ← equation of perpendicular line
The answer to your question would be A
Answer:
y=-4 or y=-6
Step-by-step explanation:
y^2-14y+49=2y^2-4y+73
y^2+10y+24=0
(y+4)(y+6)=0
y=-4 or y=-6
Answer:
140 cubic cm
Step-by-step explanation:
Find the area of the triangular base: = 11.7.
Multiply 11.7 square cm with 12 cm to get 140.4 cubic cm.
Answer:
48 / x = 8
x = ?
Basic multiplication & division but x = 6
6 * 8 = 48
1. 8 * 1 = 8 + 0 = 8
2. 8 * 2 = 8 + 8 = 16
3. 8 * 3 = 8 + 8 + 8 + 24
4. 8 * 4 = 8 + 8 + 8 + 8 + 32
5. 8 * 5 = 8 + 8 + 8 + 8 + 8 = 40
6. 8 * 6 = 8 + 8 + 8 + 8 + 8 + 8 = 48
I'd recommend practicing with some mulitplication flashcards. One of the best things I ever did! :)
