Answer:

y=2x+7

Step-by-step explanation:

Since the answer HAS to be parallel to the line y=2x-4, that means the only number that should change is the y-intercept (the last number in the equation.) y-intercept is the x-value when y=0, which basically means, if you put the line onto a graph, look for the point when the line passes through the y-axis, then look at how far up or down that point is (x-value). That will be your answer. Since the line passes through the y-axis at x=7, the answer is y=2x+7! Sorry if this is too confusing, I'm not good at teaching XD

Answer:

b

Step-by-step explanation:

Answer:

∠2 and ∠5 should not be Alternate exterior angles. ∠2 and ∠11 can be Alternate exterior angles if that is an option. The rest is correct. As for consecutive interior angles, you have (∠3 and ∠9), (∠4 and ∠10), (∠7 and ∠13) and (∠8 and ∠14).

Step-by-step explanation:

Alternate exterior angles are basically like the angles that are the combination of a vertically opposite angle and a corresponding angle. Since the vertical lines are not parallel, ∠2 and ∠5 cannot be Alternate exterior angles.

Consecutive interior angles are any pair of angles that are within a pair of parallel lines and add up to 180°.

Answer:

Graph A passes THrough the Center making it proportional when graph B is not passing

Step-by-step explanation:

Answer:

that is y

Step-by-step explanation:

Graph A is proportional because it runs thru the origin while the other doesn't

Answer:-3/5

Step-by-step explanation:

Rise over run

Answer:

Step-by-step explanation:

x - 6 = 0

x = 6

f(x) = 2x⁴  + x² - 8x - 1

     =2(6)⁴+ 6² - 8*6 - 1

     = 2*1296 + 36 - 48 - 1

     = 2592 + 36 - 48 - 1

     = 2628 - 49

     = 2579

Answer:  [tex](-\infty, -4][/tex]

Curved parenthesis at negative infinity

Square bracket at -4

====================================================

Work Shown:

[tex]5(x+4) \le 0 \\\\x+4 \le \frac{0}{5} \\\\x+4 \le 0 \\\\x \le 0-4 \\\\x \le -4 \\\\[/tex]

The last inequality shown above is the same as saying [tex]-\infty < x \le -4[/tex]

Converting this to interval notation leads to the final answer of [tex](-\infty , -4][/tex]

Note the use of a square bracket at -4 to include this endpoint. We can never include either infinity, so we always use a parenthesis for either infinity.

Answer:

( C ) p5 / q4

Step-by-step explanation:

Answer:

a. 2/5

b. 1/2

c. 100/9

Step-by-step explanation:

a: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:

.12 × 100 = 12

.3 × 100 = 30

Simplify: 12/30 = 2/5

b: Multiply bottom and top by 1,000 to keep values the same and make the fraction a whole fraction:

.125 × 1,000 = 125

.25 × 1,000 = 250

Simplify: 125/250 = 1/2

c: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:

4 × 100 = 400

.36 × 100 = 36

Simplify: 400/36 = 100/9

The intersection point of a system of equation is the solution of the system.

The solution to the system of equations is (2,5)

The equations are given as:

[tex]\mathbf{5x - y = 5}[/tex]

[tex]\mathbf{5x + y = 15}[/tex]

See attachment for the graphs of [tex]\mathbf{5x - y = 5}[/tex] and [tex]\mathbf{5x + y = 15}[/tex]

From the graph, the point of intersection is (2,5).

Hence, the solution to the system of equations is (2,5)

Answer:

5) 2(4 - n) = -3n

2 × 4 - 2 × n = -3n

8 - 2n = -3n

-2n + 3n = -8

1n = -8

n = -8/1

n = -8

6) 5 - 3(2 + 2w) = -7

5 - 3 × 2 + -3 × 2w = -7

5 - 6 - 6w = -7

-1 - 6w = -7

-6w = -7 + 1

-6w = -6

w = -6/-6

w = 1

7) 5(2r + 3) - 5 = 0

5 × 2r + 5 × 3 - 5 = 0

10r + 15 - 5 = 0

10r + 10 = 0

10r = -10

r = -10/10

r = -1

8) 3 - 5(2d - 3) = 4

3 - 5 × 2d - 5 × -3 = 4

3 - 10d + 15 = 4

-10d + 15 + 3 = 4

-10d + 18 = 4

-10d = 4 - 18

-10d = -14

d = -14/-10

d = 7/5

Answer:

There will be 416 students in each group.

Step-by-step explanation:

There are 1,248 students.  There are also 3 groups: radical readers, mathematicians, and super scientists.  To find the number of people in each group, divide the total students by the number groups, which would be 1,248 divided by 3.

Answer:

C

Step-by-step explanation:

Try using a scratch piece of paper to graph the points of each table to see which one would have a negative slope. Or use the formula y1-y2/x2-x1 to find the slope and see which one is negative.

So you want to go to your calculator type 42 divided by zero, and you should get a 52.5.
