Containing the points (-1,2) and (5,-4)

Answers

the equation conatining the points would be
y=mx+b, m=slope b=y inercept
find slope

slope=(y1-y2)/(x1-x2)=(2-(-4))/(-1-5)=(6)/(-6)=-1

slope is -1
y=-1x+b

input one of the points and solve for b
2=-(-1)+b
2=1+b
subtract 1 form both sides
1=b

answer=
y=-1x+1

Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?

Answers

Let

n-------> the number of nickels

d-------> the number of dimes

we know that

1\ nickel=\$0.05

1\ dime=\$0.10

so

0.05n+0.10d=13.30 -----> equation A

n+d=175

d=175-n -------> equation B

substitute equation B in equation A

0.05n+0.10(175-n)=13.30 ------> equation that can be used to find n

Solve for n

0.05n+17.5-0.10n=13.30

17.5-13.30=0.10n-0.05n

0.05n=4.2

n=84\ nickel

find the value of d

d=175-n

d=175-84=91\ dimes

therefore

the answer is

The equation that can be used to find n is 0.05n+0.10(175-n)=13.30

The number of nickels in the collection is 84\ nickel
n + d = 175 .... d = 175 - n
0.05n + 0.10d = 13.30

0.05n + 0.10(175 - n) = 13.30 <== and u would just solve for n

Need help. 35-(-55)=?

Answers

the answer is 90.Remember that whenever you see two - signs right next to eachother it turns into an addition sign
Remember that subtracting a negative number is the same as adding a positive number.(two negatives equals a positive) For example:

35-(-55)=35+55

They are both equivalent. Now we can solve..

35+55=90

Answer=90

Using the distributive property to find the product (y – 4)(y2 + 4y + 16) results in a polynomial of the form y3 + 4y2 + ay – 4y2 – ay – 64. What is the value of a in the polynomial?

Answers

( y - 4 ) ( y² + 4 y + 16 ) = y³ + 4 y² + 16 y - 4 y² - 16 y - 64
The result is a polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y + 64;
Answer: a = 16

What is the value of x log3 x=4

Answers

Answer:

x=81

Step-by-step explanation:

Rewrite log_3 (x)=4 in exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then log_b(x)=y is equivalent to b^y=x.

Rewrite the equation as x=3^4

Raise 3 to the power of 4 

x=81
