a slope-intercept equation of the line whose graph is perpendicular to
2x + 9y = 8 and has the y-intercept (0, -3)
Step-by-step explanation:
let eqn be y = mx + b.
2x + 9y = 8
9y = -2x + 8
y = -2/9 x + 8/9
since the lines are perpendicular, product of the slope of the two lines = -1.
hence,
m x -2/9 = -1
m = 9/2
sub (0, -3):
-3 = 9/2(0) + b
b = -3
therefore equation is: y = 9/2x - 3

find the x if the sum of three numbers is 180 and the numbers are 45,68,(3x+16)
Answer:
x = 17
Step-by-step explanation:
[tex]45 + 68 + (3x+16) = 180 \\ \\ 113 + 3x + 16 = 180 \\ \\ 129 + 3x = 180 \\ \\ 3x = 180 - 129 \\ \\ 3x = 51 \\ \\ x = \frac{51}{3} \\ \\ x = 17[/tex]
How do I solve this equation?
Answer:
so you need to find x
Step-by-step explanation:
the little fraction beside the equation in parenthesis is what you are multiplying by, and 25 is what is equals , so x-7 times 2/3 or 0.67 = 25 we then divide 25 by 0.67 then plus 7 and the answer is 44.31

Julie had $10.00 in her savings account when she earned $23.50 doing errands for her next-door neighbor. Julie used her savings and her earnings to buy a new pair of shoes that cost her $27.75. How much did she have left in her account after she bought her shoes?
Answer:
$5.75Step-by-step explanation:
Step one:
given data
initial balance= $10
she earned extra $23.50 doing errands
hence her balance will be
=10+23.5
=$33.5
Step two:
Required is her balance
we are told that she bought shoes for $27.75
hence her balance will be
=33.5-27.75
=$5.75
What’s the answer to this question ?
Answer:
∠ C = 44°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
4x - 16 +6x - 1 + 4x - 13 = 180°
14x - 30 = 180 ( add 30 to both sides )
14x = 210 ( divide both sides by 14 )
x = 15
Thus
∠ C = 4x - 16 = 4(15) - 16 = 60 - 16 = 44°
Solve for X .. I know it’s two questions but I’m having a hard time

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
141° is an exterior angle, thus
x + 24 + 2x + 12 = 141 , that is
3x + 36 = 141 ( subtract 36 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
-----------------------------------------------------------
(11)
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
2x - 9 + 3x + 2x = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
Answer:
Unfortunately I can't do the first one, but the second one is easy
Step-by-step explanation:
To find X in the Q) 11:
1. The triangle is an equilateral traingles meaning angles add up to 180°
2. Add the numbers - 2x - 9 + 3x + 2x = 7x -9
3. Add 9 to 180 (your adding because you changed the side of the number) - 189 = 7x
4. Divide 7 by 189
Your answer is x = 27

Glenda makes an online purchase of 4 picture frames for $12.95 each and 4 mats for $5.89 each. The site says that taxes paid by the customer are 6.5% of the total purchase price. Shipping charges are based on the following table: Amount of Purchase Standard Shipping Express Shipping up to $50 $5.10 $7.00 $50 up to $100 $6.35 $8.20 $100 up to $200 $7.80 $11.60 $200 and over $10.50 $16.45 Glenda selects express shipping for her purchase and the company bills her credit card $91.86 for the total of the online purchase. Determine if Glenda has been billed correctly for her purchase. a. Glenda has been billed correctly. b. Glenda has not been charged enough for her purchase. c. Glenda has been over charged by $3.40 for her purchase. d. Glenda has been over charged by $3.80 for her purchase.
Answer:
C: Glenda has been over charged by $3.40 for her purchase
Step-by-step explanation:
The amount Glenda is to pay can be found by applying arithmetic
operations to the given parameters in the correct order.
The correct option is; c. Glenda has been overcharged $3.40 for her purchase.Reasons:
The price of each picture frame = $12.95
Number of picture frame purchased = 4
Price of each mat = $5.89
Number of mats purchased = 4
Total purchase price = $12.95 × 4 + $5.89 × 4 = $75.36
Total purchase price + Tax = $75.36 × 0.065 + $75.36 ≈ $80.26
Express Shipping charges for amount of purchase between $50 to $100 is given from the table as; $8.20
Total bill = Total purchase + Tax + Shipping
Therefore;
Total bill = $80.26 + $8.20 = $88.46
Amount the credit card is billed = $91.86
Amount of over charge = $91.86 - $88.46 = $3.40
Therefore, Glenda has been over charged by $3.40 for her purchase
