Question 1 of 10
Which of these points lies on the line described by the equation below?
y-3 = 5(x - 9)
A. (9,3)
B. (3,9)
C. (-9,-3)
D. (-3,-9)
SUBMIT

Answers

Answer 1

Answer:

Step-by-step explanation:

Plugin x and y value in the equation. If both sides are equal, then the points lie on  the line,

1) (9 , 3)

y - 3 = 5(x -9) ;  x = 9 & y = 3

3 - 3 = 5 *(9 - 9)

0     = 5*0

   0   = 0

(9, 3) lies on the described line.

2) (3 , 9) ; x =3 & y = 9

9 - 3 = 5( 3 - 9)

  6   = 5*(-6)

  6 ≠ -30

(3 , 9) does not lies on the described line.

3) (-9, -3)  ; x = -9  & y = -3

-3 - 3 = 5(-9 - 9)

 - 6 = 5 * (-18)

  -6   ≠ -90

(-9 , -3) does not lies on the described line.

4) (-3, -9)

-9 - 3 = 5 (-3 - 9)

-12     = 5*(-12)

   -12 ≠ -60

(-3 , -9) does not lies on the described line.

DEGREE MEASURE:

When the arc is shown, and the lines that designate where the arc is go through the center, then the degree is the same as that marked on the circle. The degree measure of arc AB is 120 degrees.

LENGTH:

The length of an arc can be found using the formula for the circumference of a circle. The formula for the circumference of a circle is C = pi * diameter. The circumference of this circle is 40pi inches. Now, arc AB is only 120 degrees of the whole circle. 120 / 360 = 1/3. Therefore, we need to divide the circumference by 3. The length of arc AB is (40pi)/3 inches.

In the question you will do

So you will do 35=21 to the power x +x

So after you do it it will be

X=441 -35 it will be 406 and after you finish you will do it in the calculator so

The Answer is : 20.15
Theres an easier way. Pythagorean theorem-
A^2+B^2=C^2
A and B are legs while C is the hypotenuse or slanted one.
So rearrange formula.
C^2 - A^2=B^2
1225 - 441 = B^2
784= B^2
Square root it now

Students sold 390 tickets for a fundraiser at school.
Some tickets are for children and cost $2, while the
rest are adult tickets that cost $5. If the total value of
all tickets sold was $1,470, how many of each type of
ticket was sold?

Answers



a = number of adult tix = 230
c = number of child tix = 160

a + c = 390 for number of tickets sold
5a + 2c = 1470 for money earned

First we’ll solve for c in terms of a
c = 390-a

Then we’ll substitute that expression in to solve for a numerical value for c:

5a + 2c = 1470
5a + 2(390 - a) = 1470
5a + 780 -2a = 1470
3a = 690
a = 230

Then we’ll drop that into the first equation to get a numerical value for c

c = 390 - a
c = 390 - 230
c = 160

Check the math:
5a + 2c = 1470
5(230) + 2(160) =
1150 + 320 = 1470

Dairy Queen Restaurant charges $4.00 for a Mini-Blizzard (a type of ice cream treat) and $0.50 per additional candy topping that the customer wishes to mix-in. You determine that a linear model is a good way to represent this information. A. What is the rate of change (slope, m, with units): __A___ ____ B. What is the y-intercept: __B___ ____ C. Create a linear model in y = mx + b form for this situation:

Answers

Answer:

Slope = $4.00

y - intercept = $0.50

y = 4x + 0.5

Step-by-step explanation:

Given :

Cost of Mini blizzard = $4.00

Cost of optional or additional topping = $0.50

A linear model is in the form:

y = mx + b

For this scenario

y = total cost of order

m = slope Coefficient = cost of mini blizzard

x = number of mini blizzards ordered

c = additional cost, cost of candy topping

Hence, rate of change, slope, m = cost of mini blizzard = $4.00

The y - intercept = cost of candy topping = $0.50

In triangle ABC, the measure of angle CAB is 80° and the measure of angle ABC is 45.5°. What is the measure of angle BCA in degrees? A 125.5°125.5 degrees B 54.5°54.5 degrees C 55.5°55.5 degrees D 64.5°

Answers

Answer:

B 54.5°

Step-by-step explanation:

Since we have a triangle,

CAB + ABC + BCA = 180 (sum of angles in a triangle)

Since CAB = 80° and ABC = 45.5°, substituting these into the equation, we have

80° + 45.5° + BCA = 180°

simplifying, we have

125.5° + BCA = 180°

collecting like terms, we have

BCA = 180° - 125.5°

BCA = 54.5°

So, the answer is B

Answers

W = 5

-4w - 4 = -24
+4 +4
-4w = -20
-4w/-4 = -20/-4
w = 5

Answer:

The answer is w = 5.

Step-by-step explanation:

1) Divide both sides by -4.

[tex]w + 1 = \frac{ - 24}{ - 4} [/tex]

2) Two negative numbers makes a positive.

[tex]w + 1 = \frac{24}{4} [/tex]

3) Simplify 24/4 to 6.

[tex]w + 1 = 6[/tex]

4) Subtract 1 from both sides.

[tex]w = 6 - 1[/tex]

5) Simplify 6 - 1 to 5.

[tex]w = 5[/tex]

Therefor, the answer is w = 5.
