x2-x1 =a+2-a=2
y2-y1= 3x2 +2 -3x1 -2= 3(x2-x1)=3*2=6
correct answer is C
if D, then
y2-y1=9(x2-x1)=9*2=18, so D is wrong
X would be square root of 10 because u would do properties
X/7 = 0.4 => x = 7 x 0.4 = 2.8
7/y = 0.4 => y = 7 : 0.4 = 17.5
If the shoes cost 95 dollars and are at a 30% discount then we know that the shoes cost 70% of its original price. we would write this as 95 x .7 which is 66.50 dollars. The tax would up the price. To do this we need to add a 1 to whatever the tax percentage is. this would then be written as 1.07 x 66.50 and the answer is 71.155. since you can’t pay that amount you have to round up to the near test hundredth. Since the number in the thousandth spot is 5, we round up making your final price 71.16 dollars.
