Answer: 6 hours
Step-by-step explanation:
Taylor cannot spend over $260.
Subtract the cost of the part needed for the repair:
= 260 - 80
= $180
$180 is left for fixing the car after buying the part.
As the labor costs $30 and now she cannot exceed $180 for labor, the total number of hours the mechanic can work is:
= 180 / 30
= 6 hours

Answer:
A. y = 4/3x -4
Step-by-step explanation:
The y-intercept in the slope-intercept formula, y = mx + b, is b. This represents where the x is 0 on the graph. The line on the given graph has a y-intercept at (0, -4). Therefore we are looking for a formula with y = mx - 4. This gets rids of the choices C. and D.
The slope of a line is rise over run. So, how many points do you go up divided by how many points you go right. According to the given graph, to get from (0, -4) to (3, 0) you need to go up 4 and to the right 3. Since slope is rise over run, m = 4/3.
This gets rid of option B., leaving us with A. y = 4/3x - 4.
We will calculate it like this, We will make a right angle triangle by adding one new point called O for example, and O is located right under the point C, and on the right side of point D, so the coordinated for this point are O (8, -2). From there, length CD is calculated using the Pythagorean theorem, because we know that the CO = 4 and DO = 4, so:
CD^2 = CO^2 + DO^2
CD^2 = 4^2 + 4^2
DC^2 = 16 + 16
DC^2 = 32
DC = square root of 32 = square root of 16 * square root of 2
DC = 4 * square root of 2
The correct answer is B. 4*square root of 2.
