Step-by-step explanation:
6 x (-13) = -78
x - 5 = -78
x = -78 + 5
x = -73
a quadratic function that fits the points (0,5) (2,3) (4,9)
Answer:
Step-by-step explanation:
y=ax^2+bx+c we are given point (0,5) so if x=0, y=c, so c=5. We have two other points
(2,3)(4,9) which gives us
4a+2b+5=3 and 16a+4b+5=9
Subtracting twice the first from the second
16a+4b+5-8a-4b-10=9-6
8a-5=3
8a=8, so a=1, so using 4a+2b+5=3 we get
4(1)+2b+5=3
2b+9=3
2b=-6
b=-3 so our quadratic is
y=x^2-3x+5
is x equals 12 a solution to the equation 6 + x = 19
Answer:
13
19 minus 6 is equal to 13 so your answer would be thirteen

Step-by-step explanation:
5 2/5 divided by 9/10
Answer:
Step-by-step explanation:
5 2/5 = [(5*5)]+2 / 5 = (25+2) / 5 = 27/5
(27/5)/(9/10) = 27/5 * 10/9
cross cancel 27 becomes 3 and 9 becomes 1, 5 becomes 1 and 10 becomes 2
= 3/1 * 2/1 = 6/1 = 6
Which of the following is a reflection of ( 2,4 ) across the x-axis?
a -2, 4
b 2, -4
c 4, 2
d -2, -4
Answer:
(2,-4)
Step-by-step explanation:
(2,4) is located in Quadrent I (+,+), if you reflect over the x-axis, it would be in Quadrent IV (+,-).
if you dont understand I suggest you draw a coordinate plane on a graphing notebook.
the measure of b is?
Answer:
35.228
Step-by-step explanation:
Answer:
b=21
Step-by-step explanation:
For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):
20^2+b^2=29^2
Simplify the squares:
400+b^2=841
Subtract 400 from both sides:
b^2=441
Take the square root of both sides:
b=21

What is the equation of the line that passes through the point (-8,-6) and
has a slope of 1/4
Answer:
y = 1/4x -4
Step-by-step explanation:
Since you know that that slope int. equation is y = mx+b, and the m is the slope just plug in the slope in the equation. So it will be y = 1/4x + b.
Then what you will do is solve for b in the equation. So what you do is plug in the x and y value from the coordinate given in the equation, so it will be like this: -6 = 1/4(-8) +b
-6 = -2 +b
-4 = b
b = -4
So then you plug back the b value into the equation with slope to wtite the equation. So it would be, y = 1/4x -4

Mary needs to buy 4 concert tickets and one parking pass. If parking is $12, and she can spend at most $80, what ticket prices can she afford? (set up an inequality, do not solve)
Answer:
4t + 12 [tex]\leq[/tex] 80
Step-by-step explanation:
Set up an inequality where t is the cost of one ticket
Since her budget is $80, a less than or equal sign needs to be used.
4t will represent the total cost of the tickets, since she needs to buy 4. Add 12 to this to represent the parking cost:
4t + 12 [tex]\leq[/tex] 80 is the inequality.

b= 16 mm
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2= c^2, so-
12^2 +b^2= 20^2
144+b^2=400
b^2=400-144
b^2= 256
b= 16
Answer:
16 mm
Step-by-step explanation:
A²+B²=C²
12²+x²=20²
144+x²=400
x²=400-144
x²=256
√x = √256
x = 16

The net of a triangular prism is show below.Find the rotal surface area of the triangular prism 4.6,4,5,15
Answer:
228.4cm²
Step-by-step explanation:
Find the diagram attached
Total surface area of the prism = Ph + 2B
P is the perimeter of the base (triangle)
h is the height of the prism
B is Base area
P = 5cm + 5cm + 4cm
P = 14cm
h = 15cm
B = 1/2 * base * height
B = 1/2 * 4.6 * 4
B = 4.6 * 2
B = 9.2cm²
Substitute the values into the formula;
Total surface area of the prism = Ph + 2B
Total surface area of the prism = 14(15)+2(9.2)
Total surface area of the prism = 210 + 18.4
Total surface area of the prism = 228.4cm²
Hence the total surface area of the triangular prism is 228.4cm²

Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6
Answer:
-27
Step-by-step explanation:
8x - 6 - 7y + 3
X = 3 Y = 6
8(3) - 6 - 7(6) + 3
8 x 3 = 24
7 x 6 = 42
24 - 6 - (42 + 3)
(24 - 6) - 45
18 - 45 = -27

After tax, what was the total cost she paid for the sweatshirt? *
$8.00
$38.64
$3.36
$45.36
Answer:
$45.36

100 + 8 = 108
42/100 X 108 = 45.36
100 + 8 = 108
42/100 X 108 = 45.36
