Answer: 7 7/8

Step-by-step explanation: follow PEMDAS and work what’s in the parentheses first... 4 1/8 + 6 1/4= 10 3/8 then you subtract 2 1/2 and your final answer should be 7 7/8

If g(x) = -5x + 13, find g(-1)
givi [52]

To solve this problem, we must substitute the value of -1 in for x in the function. This means that for every x there is in the equation, we must substitute the value -1 in for it in order to find the value of g(-1). This is modeled below:

g(x) = -5x + 13

g(-1) = -5(-1) + 13

Next, we must simplify using the order of operations. PEMDAS outlines this concept, telling us to simplify parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. In this case, we will solve the multiplication and then the addition, as modeled below:

g(-1) = -5(-1) + 13

g(-1) = 5 + 13

g(-1) = 18

Therefore, your answer is 18.

Hope this helps!

Which ordered pair can be included in the table of values shown below for the equation p=25x-2?
pishuonlain [190]

Answer:

(0,-2)

Step-by-step explanation:

So since you are given the equation, p=25x-2, all you really need to do is plug in the ordered pairs and see which satisfies the equation.

This means makes both side have the same number value.

Let's try (x,p)=(-2,-2):

 p=25x-2 with (x,p)=(-2,-2)

-2=25(-2)-2

-2=-50-2

-2=-52

-2 and -52 do not represent the same number so (-2,-2) is not a point on the given line.

Let's try (x,p)=(-2,0):

p=25 x -2 with (x,p)=(-2,0)

0=25(-2)-2

0=-50-2

0=-52

0 and -52 do not represent the same number so (-2,0) is not a point on the given line.

Let's try (x,p)=(0,-2):

p=25 x  -2 with (x,p)=(0,-2)

-2=25(0)-2

-2=0   -2

-2=-2

-2 and -2 are the same number and so (0,-2) is a point on the line.

Let's try (x,p)=(0,0)

p=25 x  -2 with (x,p)=(0,0)

0 =25(0)-2

0 =  0   -2

0 =   -2

0 and -2 are not the same number so (0,0) is not a point on this line.

How do I solve 8n= -3m + 1 ; n= -2, 2, 4
Dennis_Churaev [7]
8n = -3m + 1
n = -2, 2,4
first add -2, 2 and 4 which = 4 
then do 8(4) = -3m +1 which makes 24 = -3m +1 so subtract 1 on both sides then you have 23 = -3m divde -3 on both sides which equal -7.66 or 8
