K(x) k(-3) 2x^2-5x+3

Answers

Answer 1

Answer:

When k(x) is 2x² - 5x + 3, k(-3) = 36.

Step-by-step explanation:

k(x) = 2x² - 5x + 3

Substitute the input of x.

k(-3) = 2(-3)² - 5(-3) + 3

Square -3.

k(-3) = 2(9) - 5(-3) + 3

Multiply 2 and 9.

k(-3) = 18 - 5(-3) + 3

Multiply -5 and -3.

k(-3) = 18 + 15 + 3

Add 18 and 15.

k(-3) = 33 + 3

Add 33 and 3.

k(-3) = 36.

If angle 5 measures 110 degrees , what is the measure of angle 2?

A) 55 degree
B) 70 degree
C) 110 degree
D) 160 degree

Answers

Answer:

the vertex is 70 degrees and the other 2angles are 55 degrees each

 

in a triangle the angles must total to 180 degrees.

if the exterior angle is 110 degrees the supplementary angle of this angle would be = 180-110= 70 degrees

as it is an isosceles triangle the other two angles must be equal.

such that x+x+70= 180 , where x are the angles of the base

2x= 180-70

2x=110

x=110/2

x= 55

She was able to purchase coach tickets for $​360 and first class tickets for ​$970. She used her total budget for airfare for the​ trip, which was ​$5320. How many first class tickets did she​ buy? How many coach tickets did she​ buy?

Answers

Answer:

$3990

Step-by-step explanation:

So first,you need to add the dollars that Sarah spend and which is equal to $1330($360+$970) and you need to subtract the money that Sarah spend($1330) and the budget of her money ($5320) so which is $5,320-$1,330 so the answer is $3,990

A line passes through point. (6, -8) and has a slope of -3/2

Write an equation in Ax+By=C form for this line.

Answers

Answer:

3x + 2y = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{3}{2}[/tex] , then

y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute (6, - 8 ) into the partial equation

- 8 = - 9 + c ⇒ c = - 8 + 9 = 1

y = - [tex]\frac{3}{2}[/tex] x + 1 ( multiply through by 2 to clear the fraction )

2y = - 3x + 2 ( add 3x to both sides )

3x + 2y = 2 ← in standard form

29. Find the missing coordinate that would result in the given slope. (x, 2) and (5, -4) if m= -3​

Answers

Answer:

Set up an equation (you can use the distance formula as an equation). The distance formula is Y2-Y1/X2-X1.

2-(-4)/x-5=-3

6/x-5=-3

Multiply both sides by x-5.

6=-3(x-5)

Distribute the -3 to the terms in the parentheses.

6=-3x+15

Subtract 15.

-9=-3x

Divide both sides by -3.

3=x

So, the missing number of the coordinate is 3.

The admission fee at an amusement park is $1.50 for children and $4.00 for adults. On a certain day, 2,900 people entered the park, and the
admission fees that were collected totaled $6,100. How many children and how many adults were admitted?

Answers

Step-by-step explanation:

x= children

y= adult

First equation: x+y= 2900

Second equation: 1.50x + 4y= 6100

From first equation: x+y= 2900

x= 2900-y, becomes the third equation

Second equation: 1.50(2900-y) + 4y= 6100

4350-1.50y+ 4y= 6100

2.5y = 1750

y= 700

700 adults

Thrid equation: x= 2900-700

= 2200

2200 children

So total have 700 adults and 2200 children

You put $500 in a savings account. The account earns $15.75 simple interest in 6 months. What is the annual interest rate?

Answers

Answer:

6.3%

Step-by-step explanation:

We're gonna use the simple interest formula: A = P(1 + rt)

A = Final amount (500 + 15.75 = 515.75)

P = Starting amount (500)

r = rate (?)

t = number of years (.5 since it's been half a year)

515.75 = 500(1 + 0.5r)

Disitribute the 500 to the equation inside the parenthesis

515.75 = 500 + 250r

Subtract 500 from both sides

515.75 = 500 + 250r

- 500   - 500

15.75 = 250r

Divide both sides by 250

15.75/250 = 250r/250

r = 0.063

SHOW ALL WORK WILL MARK BRAINLIEST

Answers

Answer:

26

Step-by-step explanation:

[(7+3)5-4]/2+3

-To solve this equation you have to use PEMDAS

P- Parentheses

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction-

- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])

Step 1) [(10)5-4]/2+3

- First you do "P," parentheses, so you add 7+3=10

Step 2) [50-4]/2+3

- Next you do "M," multiplication, and multiply 10x5=50

Step 3) [46]/2+3

- Then you do "S," subtraction, and subtract 50-4=46

(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)

Step 4) 23+3

- Now we do "D," division, and divide 46/2=23

Step 5) 23+3=6

- Finally we do "A," addition, and add 23+3=26 so the answer is 26
