PLs solve it RN I need it for my math class. okay so you are smart pls solve this problem.

Answer: D

Step-by-step explanation:

Solve for y: y (greater than or equal to) (7-9x)/5

Slope is negative (-1.8x) so it must be A or D

Choose a test point to plug in. (0,0) works. If plugging in 0 for x and y yields a true inequality, then the area with (0,0) should be shaded. Since the result for plugging in (0,0) is 0 greater than or equal to 1.4, choose the shaded area without (0,0).

Answer:

y = 3x-3

Step-by-step explanation:

first we need to find the slope, which is change in y over change in x, and therefore the slope is 3, then we plug in a point giving us 3x-3

Answer:

The answer is option 2, y=3x-3.

Step-by-step explanation:

The best way to figure these out imo is to just test to see if its true. for example to test option 2 you would simply multiply x by 3, and subtract three, and if it works then that's the answer.

Answer:

Common denominator of 2 and 5 if you want to add or subtract two fractions with 2 and 5 as denominators.

Step-by-step explanation:

Step 1) Take the LCD and divide each denominator by it as follows:

10/2 = 5

10/5 = 2

Step 2) Multiply each nominator with the respective answers from Step 1:

3 x 5 = 15

2 x 2 = 4

Step 3) Put it all together to solve the problem:

15/10 + 4/10 = 19/10

= 3/2 + 2/5 = 19/10

=10

Answer:

It's 10

Answer:

3) answer is 120     4) 105

Step-by-step explanation

3)     180 - (70+50) = 60

         180-60 = 120 <-- thats the answer

4) 180 - ( 80+25) = 75

     180 -  75 = 105 < thats the answer

Answer:

0 is the answer

Step-by-step explanation:

Answer:

It must be proportional because the graph is a straight line passing through the origin.

Step-by-step explanation:

Answer:

It cannot be proportional because the straight line through the points does not go through the origin.

Answer:360 hours

Step-by-step explanation:You have to add to get you answer.I will show you how I got 360:

70+20=90

90+20=110

110+250=360

Your answer is: 360 hours

hope this is helpful :)

Answer:

yes

Step-by-step explanation:

for a function to be a.. function every input must have a different output, that's pretty much it, but at the same time you can still have the same output as long as the input is different and the input only gives that one output

Answer:

The slope of the line is -3/5

The y-intercept of the line is 14/5

Step-by-step explanation:

Equation of a line

A line can be completely defined by two points. Suppose we know the line passes through points A(x1,y1) and B(x2,y2).

The equation for a line can be written as:

[tex]y=mx+b[/tex]

Where m is the slope and m is the y-intercept. Both values can be determined by using the coordinates of the given points.

First, determine the slope with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The points are: A(-3,1) B(7,-5)

[tex]\displaystyle m=\frac{-5-1}{7-(-3)}[/tex]

[tex]\displaystyle m=\frac{-6}{7+3}=\frac{-6}{10}[/tex]

Simplifying by 2:

[tex]\displaystyle m=-\frac{3}{5}[/tex]

The slope of the line is -3/5

Using this value in the equation of the line:

[tex]\displaystyle y=-\frac{3}{5}x+b[/tex]

Use any of the given points to find b. Susbstituting point A(-3,1):

[tex]\displaystyle 1=-\frac{3}{5}(-3)+b[/tex]

Operating:

[tex]\displaystyle 1=-\frac{9}{5}+b[/tex]

Moving the constants to the left side:

[tex]\displaystyle 1+\frac{9}{5}=b\Rightarrow b=\frac{14}{5}[/tex]

[tex]\boxed{\displaystyle b=\frac{14}{5}}[/tex]

The y-intercept of the line is 14/5

Answer:

40

Step-by-step explanation:

Step 1: Define

2r(t - 1)

r = 4

t = 6

Step 2: Substitute and Evaluate

2(4) · (6 - 1)

8 · 5

40

Answer:

40

Step-by-step explanation:

2r (t – 1)

Let r= 4 and t = 6

2*4 ( 6-1)

PEMDAS says parentheses first

2*4(5)

Then multiply from left to right

8 ( 5)

Hi there !

60% ............... 75

100% ................x

x = 100*75/60 = 7500/60 = 125

Good luck !

Answer: 90

Step-by-step explanation: The mean of a data set is equal to the

sum of the set of numbers divided by how many numbers are in the set.

So to find the mean of the data set

shown here, begin by adding the numbers.

Adding the numbers, we get 720.

This will be divided by the number of numbers in the set, or 8.

So we have 720/8 or 90.

So the mean of the data set shown here is 90.

Answer:

f(3)=-11

Step-by-step explanation:

Plug in what you know so: -3(3)-2

Multiply: -9-2

Subtract: -11

Answer:

Step-by-step explanation:

Using addition, subtraction, multiplication, or division, there is fundamentally only one way to make the target number from the four given numbers using each one once:

  multiply 7 and 3, add 9 and subtract 14:

  16 = 3×7 +9 -14

If you want two expressions, rearrange this to form a different expression. One possibility is ...

  16 = 9 + 3×7 -14

Answer:

40

Step-by-step explanation:

1 hour = 60 minutes

60/15 = 4

10 × 4 = 40

Answer:

|4 - 7| = |-3| = 3

|z| is interpreted as the absolute value of z, which is the distance from 0 to z.

|4 - 7| + 5*2 = 3 + 10 = 13.

Laura got the answer wrong.

Answer:

x=11

Step-by-step explanation:

65+3x+4+78=180

Combine like terms

147+3x=180

Subtract 147 on both sides

3x=33

Divide by 3

x= 11

Answer: 11 degrees

Step-by-step explanation:

65+3x+4+78=180

147+3x=180

3x=33

x=11
