Answer:

y = 7/4x - 3

Step-by-step explanation:

y = mx + b

y = 7/4x - 3

Answer:  Let the 2 numbers be x and  

sum of two numbers is 28....Eq 1:  x + y = 28

sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2:  6x + 3y = 105

Rearrange Eq 1 to solve for x.

x + y = 28

x = 28 - y  --> Substitute into Eq 2, you get

6(28 - y) + 3y = 105

168 - 6y + 3y = 105

-3y = -63

y = -63 / -3 = 21

Now solve for x using Eq 1.

x = 28 - y = 28 - 21 = 7

Step-by-step explanation:

Answer: x intercept is (-6,0) and y intercept is (0,-3)

Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.

to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)

to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)

Step-by-step explanation: Tell Maria to do the problem again.

If Maria added 45,273 and 35,687 and got a sum of 70,960 : Yes, Maria's answer is reasonable.

When we add 45,273 and 35,687 we have:

45,273 + 35,687 = 80,960

Maria's response, however, is 70,960, which is 10,000 below the accurate total. This indicates that Maria most likely added incorrectly.

The rationality of the response is demonstrated by the fact that Maria's answer is considerably less than the right answer. This 10,000-difference discrepancy is not a trivial error and suggests that an addition error most likely occurred.

Answer:

x = 9

AB = 9

BC = 15

Step-by-step explanation:

x + x + 6 = 24

2x + 6 = 24

2x = 24 - 6

2x = 18

x = 18 / 2

x = 9

AB = x = 9

BC = x + 6

= 9 + 6

BC = 15

Answer: 4(5y−2)=40

Divide both sides by 4.

5y−2=  

4

40

​

Divide 40 by 4 to get 10.

5y−2=10

Add 2 to both sides.

5y=10+2

Add 10 and 2 to get 12.

5y=12

Divide both sides by 5.

y= 12/5 or 2.4 please give brainliest

Answer:

56 Burgers

Step-by-step explanation:

First, add the 3 + 4 for a total of 7, because the total of the ratio will equal the total amount of "the dinners sold".

Then divide 98/7, which will give you 14.

Then in the ration 3:4, 4 represent burgers so multiply 14 x 4.

Which gives you 56 burgers.

Answer:

[tex]f(x) = x - 1 \\ f(3) = 3 - 1 = 2 \\ f(4) = 4 - 1 = 3 \\ f(5) = 5 - 1 = 4 \\ f(6) = 6 - 1 = 5[/tex]

Answer:

See attached photograph

Step-by-step explanation:

It is a simple matter of subtracting 1 from the given x value. For example, when x=3 we need to subtract 1 away from it to find f(x); so, f(x)=2.

Side note: the term "f(x)" means "y", so when plotting this information on a graph, you will use the f(x) column as your y value.

Answer:

P' (-7, -4) , Q' (7, -8) , R' (-8, 4)

Step-by-step explanation:

Reflection in the y -axis:

The rule for a reflection over the y-axis is (x, y) → (−x, y).

P (7, -4) → P' (-7, -4)

Q (-7, -8) → Q' (7, -8)

R (8, 4) → R' (-8, 4)
