Answer:

a) 7 members,

b) 3.

c) 4.

Step-by-step explanation:

I hope the following will help you understand what this diagram means:-

The 4 people in the area overlapped by the Music and Spanish areas are the people who are in both clubs.

Obaid and Abdulraheem are in the Music Club only.

The number of members in the Music Club is these 2 plus the 4 in the overlap area, so there are 6 members in the Music Club.

What is the value of x in the equation 2(6x+4) - 6+ 2x - 3(4x+3)+1?

Answer:

The question is incorrect. if you are going to solve an equation for x you need to set it equal to something.

Write an equation of the line that is parallel to 2x + 4y = 6 and passes through the point (6, 4). A) y = 2x + 4 B) y = 2x - 8 C

Lynna [10]

Answer:

$\large\boxed{D.\ y=-\dfrac{1}{2}x+7}$

Step-by-step explanation:

$\text{Let}\\k:\ A_1x+B_1=C_1\\\\l:\ A_2x+B_2y=C_2\\\\\text{then}\\\\k\ \parallel\ l\iff A_1=A_2\ \wedge\ B_1=B_2\\==========================$

$\text{We have the equation:}\ 2x+4y=6\\\\\text{Therefore the equation of a parallel line is:}\ 2x+4y=C\\\\\text{Put the coordinates of the given point to the equation and solve for}\ C:\\\\(6,\ 4)\to x=6,\ y=4\\\\C=2(6)+4(4)\\C=12+16\\C=28\\\\\text{The equation in the standard form:}\\\\2x+4y=28$

$\text{Convert to the slope-intercept form}\ y=mx+b:\\\\2x+4y=28\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\4y=-2x+28\qquad\text{divide both sides by 4}\\\\y=-\dfrac{2}{4}x+\dfrac{28}{4}\\\\y=-\dfrac{1}{2}x+7$

4. What is the probability of the spinner landing on D, A, or C expressed as a decimal?

DENIUS [597]

Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35 Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)

Mark brainliest please

Hope this helps you
