Write an equation with the two points: (5,-2) and (3,4)
eimsori [14]

Answer:

y=-3x-17

Step-by-step explanation:

To find out the m(slope) of the equation use the formula:

\frac{y_2-y_1}{x_2-x_1}.

Substitute the values:

\frac{4--2}{3-5}

Combine the values:

\frac{6}{-2}

Find the value of the fraction:

-3

M is -3.

The equation so far is y=-3x+b

To find the y intercept, substitute one pair of coordinates into the equation and solve for b:

y=-3x+b\\-2=3*5+b\\-2=15+b\\-17=b.

We see that b =-17 so the full equation would be:

y=-3x-17.

Solve the inequality.
maw [93]

The solution to inequality is less than the negative of 21. Then the correct option is C.

<h3>What is inequality?</h3>

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

−(1/3)x + 10 > 17

Then the solution to the inequality will be

−(1/3)x + 10 > 17

       −(1/3)x > 17− 10

        −(1/3)x > 7

When the sign is changed then the equality sign also changed.

(1/3)x < −7

     x < − 21

The value of x is less than the negative of 21.

Thus, the correct option is C.

More about the inequality link is given below.

Find g(x)-f(x) if f(x)=-3+4 and g(x)=5x-12
Verizon [17]

Answer: g(x)-f(x)=8x-16

Explanation:

f(x)=-3x+4  (I am assuming "-3+4" is a typo and it is "-3x+4")

g(x)=5x-12

g(x)-f(x)=(5x-12)-(-3x+4)=5x+3x-12-4=8x-16

One of the digits of a two digit number is three times the other digit. If you interchange the digits of this two digit number a
STatiana [176]

Answer:

62

Step-by-step explanation:

well, we start by expressing the number:

a b

we understand that using the above expression, the value of the number is 10a + b

using the information in the question,

a = 3b (1)

and,

11b + 11a = 88 (2) (derived using 10a + b form)

hence, when substituting (1) into (2):

11b + 33b = 88

44b = 88

b = 2 (3)

sub (3) into (1)

a = 6

hence, the number is 62
