Answer 1

Answer:

Answer:

second option is correct (for question no 20)

Step-by-step explanation:

coordinate points are:

(3,1) = (x1,y1)

(5,9) = (x2,y2)

slope (m) = y2-y1/x2-x1

=9-1/5-3

=8/2

Now using slope intercept form

y=mx + b

y=4x + b

since the line passes through the point (3,1) it satisfies the equation

y=4x + b

1=4*3 + b

1-12 = b

-11 = b

substituting the value of b in equation

y=4x + b

y=4x +(-11)

y=4x - 11

Write an inequality for the situation. all real numbers y that are less than 4 or greater than 9A. y ≤ 4 or y ≥ 9

B. 4 < y < 9

C. y < 4 or y > 9

D. y < 9 or y > 4

Answers

Answer: Hello mate!

The notation:

a < b

means that the number b is bigger than the number a, and the notation:

a ≤ b

means that the number b is bigger or equal than the number a.

"all real numbers y that are less than 4"

this is written as:

y < 4

"all real numbers that are greater than 9"

this is written as:

y > 9

then, the situation can be written as:

y <4 and y >9, which means that the right answer is option C.

The Correct answer would be C... A would only be correct if they said equal to or less/greater than.

A ratio of men to women in a party is exactly 3;2 if there are a total of 120 people at the party how many of them are women ? Can someone please explain to me how the answer is 48

Answers

If the ratio is 3:2 then you add that together to get 5.Which tell you what one group would equal. Then you divide 120 by 5 to get an answer of 24. If women is equal to 2 out of a total of 5, then you multiply 24 by 2 to get 48.

Taryn bought 12.6 gallons of gasoline. There are approximately 3.8 liters in 1 gallon. Which measurement is closest to the number of liters of gasoline Taryn bought?

Answers

Answer:

Amount in liters is 47.9 liters

Step-by-step explanation:

The Question is incomplete, it does not provide the measurements or options to choose from, but we can estimate the answer

Step one:

Given data

Taryn Bought 12.6gallons of gasoline

1 gallon of gasoline is 3.8 liters

We want to convert from gallons to liters

Step two:

----if 1 gallon has 3.8 liters

then 12.6 gallons will have x liters

cross multiply we have

x= 12.6*3.8

x=47.88 liters

Hence the estimated amount in liters is 47.9 liters

Evaluate the following function is f(x)=3x-2 and g(x)=5x+1 what is -2•f(4)+3•g(1)

Answers

Answer:

work is shown and pictured

G(X) = -3/2x
Find g(4)

Answers

substitute 4 as x in both sides of the equation

basically multiply -3/2 by 4

g(x)= -3/2x

x=4

g(4) = - 3/2 * (4) = $-(3*4)/(2) = -(12)/(2) =-6$

g(4) = - 6
