How many solutions does 4(y-30)=4y+12

Anit [1.1K]

$\text{Solve for y:}\\\\4(y-30)=4y+12\\\\4y-120=4y+12\\\\\text{Subtract 4y from both sides}\\\\-120=12\\\\\text{You would see that the y variable is now non-existent}\\\\\text{This means that there are no solutions}\\\\\boxed{\text{No solutions}}$

Explain answer <br> GIVING BRAINIEST

AveGali [126]

Answer:

The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the $\frac{Rise}{Run}$ technique. Moving up 2 units and to the right 1 unit, which would be represented by $\frac{2}{1}$ .

Line m is drawn so that it is perpendicular to two distinct planes, Q and R. What must be true about planes Q and R?

UNO [17]

B. are parallel.

<span>Line m is drawn so that it is perpendicular to two distinct planes, Q and R. Therefore, planes Q and R are parallel.

Since it doesn't state that two planes intersect with each other, it is safe to assume that only line m is their connection. The planes are parallel with each other. </span>

The area of a rectangle is 5/6 sq foot. The width is 2/3 foot. The length of the rectangle is how many feet

max2010maxim [7]

Answer:

The answer is

$\frac{5}{4} \\$

Step-by-step explanation:

Area of a rectangle = length × width

Since we are finding the length

<h3> $length = \frac{area}{width} \\$ </h3>

From the question

area = 5/6 sq. feet

width = 2/3 foot

Substitute the values into the above formula and solve for the length

The length is

$length = \frac{5}{6} \div \frac{2}{3} \\ = \frac{5}{6} \times \frac{3}{2} \\ = \frac{5}{2} \times \frac{1}{2} \\ = \frac{5}{4}$

We have the final answer as

$\frac{5}{4} \\$

Hope this helps you
