Answer:

One solution

Step-by-step explanation:

Lets solve it for b

3b= -6a+12

3b= 6a-12

Simplifying

b= -2a+4

b= 2a+4

Both have same slope and intercept hence both lines are going to intersect at one point. So the equations are having one solution.

Wittaler [7]

Answer:

$a = 64 \pi x^{12}y^{8}$

Step-by-step explanation:

$r = 8x^{6}y^{4}\\a = \pi r^{2} = \pi (8x^{6}y^{4})^{2} = 64 \pi x^{12}y^{8}$

70% of what number is 21 and how do you do it

tester [92]

The answer is 30 because you put 21/x= 70/100
you cross multiply 100 and 21 you get 2100 and you divide it by 70 you should get 30 cause you take out one 0 from both numbers and end up with 210 divided by 7 then you get 30

Convert the following equation into<br> standard form.

kicyunya [14]

Answer:

7x+9y=45

Step-by-step explanation:

Standard equations always mean that you have to get x and y on one side so that they equal the coefficient.

Do this by adding the fraction that is combined with x to the other side where y is. The equation should now read $\frac{7}{9} x + y = 5$

Standard form cannot have fractions, so now you must multiply by the denominator (9) on both sides of the equation in order to cancel it out. Don't forget to multiply EACH variable by 9. This leads you to the answer.

Leona [35]

$\text{Find how much she was discounted:}\\\\\text{We know that the base price of the phone is 700}\\\\\text{It's on sale for 1/5 of the price (20\%), so multiply 700 by 0.20 and subtract}\\\\700*0.20=140\\\\700-140=560\\\\\text{Now, we know that there's a 10\% discount off the sale price, so precede}\\\text{with the same steps}\\\\560*0.10=56\\\\560-56=504\\\\\text{To find total discount price, subtract 504 from the original price}\\\\700-504=196\\\\\boxed{\$196}$
