Answer:
64
Step-by-step explanation:
Its practically just 8 times 8
False;
We are given the equation:
y = 4x - 19
This is a line with a gradient (more accurate term for slope) of 4;
The negative reciprocal of 4 is -1/4;
The other line given has a gradient of only 1/4, not -1/4, therefore, the equations do not match up with the given information.
Tip: In the situation where a line has a gradient that is the negative reciprocal of the gradient of another line, the two line will be perpendicular (i.e. the subtended angle from the point of intersection of the two lines will be 90°).
y=8x can be used to find the total amount earned by Claudia.
Step-by-step explanation:
let,
x be the number of hours and y be the amount earned.
She earned $72 for 9 hours;
9x=72
Dividing both sides by 9;
Therefore she earns 8 dollars per hour.
As the amount is same, therefore,
Amount earned = Amount per hour * No. of hours
y=8x can be used to find the total amount earned by Claudia.
