Answer: True

Step-by-Step Explanation:

=> 2x + 3y = -7 (Eq. 1)
=> -x = 2y (Eq. 2)
=> x = 1, y = -3

Substitute values of ‘x’ and ‘y’ in Eq. 1 :-

=> 2x + 3y = -7
= 2(1) + 3(-3) = -7
= 2 + -9 = -7
=> -7 = -7
=> LHS = RHS

Therefore, it is a Solution.

Covert standard form to slope-intercept form
4x + 7y + 3 = 0
7y = -4x - 3

y = (-4/7)x - 3/7 so the slope of this line is -4/7

The slope perpendicular to this is - 1 (-4/7) = 7/4
The required line has equation:-
y - 1 = (7/4)(x - (-2))
y - 1 = (7/4)x + 14/4
y = (7/4)x + 18/4 That is the answer in slope intercept form

Multiply through by 4

4y = 7x + 18

7x - 4y = 18 in Standard form Answer

A sandbox has a volume of 330 cubic feet of sand. If the sandbox is 3 feet tall, and 10 feet wide, what is the length of the san

Digiron [165]

Answer:

We are given that the total volume of the sandbox is 330 cubic feet.
We are given the side measurements of 3 feet tall and 10 feet wide.
3 x 10 = 30 sq2

V(volume)= 330 ft3

330 ft3 divided by 30 sq2 = 11ft

In conclusion, the length of the box would be:
= 11 ft

A restaurant sold 35 burgers with cheese if the ratio of the burgers sold with cheese compared to without cheese was 7 : 3 how m

Montano1993 [528]

We need to write a proportion to solve this

7/3=35/x

105=7x

divide each side by 7

15=x so, there were 15 burgers without cheese.

We could add the cheese burgers 35 to burgers without cheese 15

35+15=50 burgers were sold.
