Answer:
y=1.7x + 1.3
Step-by-step explanation:
16x + 15y =20
therefore we make the variable stand on its own
15y = 20 - 16x
Divide both sides by the variable which is 15.
it will be y= 1.3 - 1 7x
so therefore the answer is :
y= 1.7x + 1.3
Answer:24
Step-by-step explanation:
Subtract 8 from 22 = 1/4a+1/3a=14
Add the fractions together =7/12a=14
Divide 14 by 7/12 and a=24
Answer:
The answer is 5 hours.
Step-by-step explanation:
First you have to figure out how much money he already had by working at the coffee shop, so take the 15 hours and multiply it by 11$ he makes per hour and you get 165$, now you have to subtract the 200$ by 165$ to figure out how much he needs so 200 - 165 = 35 that is needed, then you keep going up an hour until your total comes above 35 so if he does 1 hour its 8, 2 hours is 16, 3 hours is 24, 4 hours is 32, and 5 hours is 40 which is finally enough to reach his goal.
Convert percent into a decimal by moving the percent sign two places to the left.
39% => 0.39
'Of' in math means multiply.
0.39 * 50 = 19.5
Answer:
After reflection over the x-axis, we have the coordinates as follows;
A’ (5,-2)
B’ ( 1,-2)
C’ (3,-6)
Step-by-step explanation:
Here, we want to find the coordinates A’ B’ and C’ after a reflection over the x-axis
By reflecting over the x-axis, the y-coordinate is bound to change in sign
So if we have a Point (x,y) and we reflect over the x-axis, the image of the point after reflection would turn to (x,-y)
We simply go on to negate the value of the y-coordinate
Mathematically if we apply these to the given points, what we get are the following;
A’ (5,-2)
B’ ( 1,-2)
C’ (3,-6)
