What is y-4= -2(x+7) written in standard form

Mathematics
1 answer:
belka [17]3 years ago
7 0

Answer:

2x + y = -10

Step-by-step explanation:

Simplify −2(x+7)

y−4=−2x−14

Move all terms containing variables to the left side of the equation.

2x+y−4= −14

Move all terms not containing a variable to the right side of the equation.

2x + y = −10

Hope this helps

Find the y-intercept for the graph of the following equation. 6x + 9y = 18
DiKsa [7]
Recall that the y-intercept is when the function passes the y-axis. This happens when x=0. Therefore, we can find our y-intercept by plugging x=0 into our function and solving for y.

6x + 9y = 18
6(0) + 9y = 18
0 + 9y = 18
9y = 18
y =2

Thus, our y-intercept is when x = 0 and y = 2, or (0,2).

1. it has at least 10 values. 2. it has at least 3 values that are different. 3. it has a mean and median of 12.
d1i1m1o1n [39]

Answer: 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17

Step-by-step explanation:

First, we can ensure that 12 is the median by putting it in the middle and putting the same amount of numbers to its left and right side. To make the values have a mean of 12, the easy why to do it is to subtrate one as you move to the left and add one as you move to the right, that way they will cancel each other out and keep the mean at 12. The answer has a total of 11 values, has more than 3 values that are different, and has a mean and median of 12.

7+8+9+10+11+12+13+14+15+16+17=132

132/11=12

There are 5 values to each side of 12, making 12 the median.

Verdich [7]

Answer:

2\ cm^{2}

Step-by-step explanation:

we know that

The area of the resulting two-dimensional cross-section is the area of a rectangle

The area of a rectangle is equal to

A=bh

we have

b=1\ cm

h=2\ cm

substitute

A=1*2=2\ cm^{2}
