Complete the table for f(x) = x2 + 2x - 3.
x -3 -2 -1 0 1
y=?
Answer:
x | -3 -2 -1 0 1
y | 0 -3 -4 -3 0
Step-by-step explanation:
f(x) = x² + 2x - 3
x = -3 then y = (-3)² + 2(-3) - 3 = 9 - 6 - 3 = 3 - 3 = 0
x = -2 then y = (-2)² + 2(-2) - 2 = 4 - 4 - 3 = 0 - 3 = -3
x = -1 then y = (-1)² + 2(-1) - 1 = 1 - 2 - 3 = -1 - 3 = -4
x = 0 then y = (0)² + 2(0) - 3 = 0 + 0 - 3 = 0 - 3 = -3
x = 1 then y = (1)² + 2(1) - 3 = 1 + 2 - 3 = 3 - 3 = 0
I need this answered please I’m in a rush
Answer:
-8, -2, 4, 10
Step-by-step explanation:
Plug the x value into the function.
2(-6)+4 = -8
and so on for all of the values in the table.
Answer:
y = 2(-6) + 4
y = -12 + 4
y = -8
y = 2(-3) + 4
y = -9 + 4
y = -5
y = 2(0) + 4
y = 0 + 4
y = 4
y = 2(3) + 4
y = 6 + 4
y = 10

Pierre has more money than Alex.
If Pierre gave Alex £20, they would have the same amount.
If Alex gave Pierre £22, then Pierre would have twice as much as Alex.
How much does each one actually have?
Answer:
Pierre has £ 146 and
Alex has £ 106
Step-by-step explanation:
Let the money with Pierre be = p
Let the money with Alex = a
If Pierre gave Alex £20, they would have the same amount.
So, we should subtract £ 20 from p and add £ 20 to a
p - 20 = a + 20
p = a + 20 + 20
p = a + 40 ----------------(I)
If Alex gave Pierre £22, then Pierre would have twice as much as Alex.
p + 22 = 2*(a -22)
p + 22 = 2a - 44
p = 2a - 44 - 22
p = 2a - 66
p -2a = - 66 -----------------(II)
Substitute p = a + 40 in equation (II)
a + 40 - 2a = -66
a - 2a + 40 = -66
-a = - 66 - 40
-a = - 106
Multiply both sides by (-1)
[tex]\boxed{a = \£ \ 106}[/tex]
Substitute a = 106 in equation (I)
p = 106 + 40
[tex]\boxed{p = \£ 146}[/tex]

c. Describe the domain of the function.
d. Describe the range of the function.
#a
H(0)
It refers to y value on graph when x is 0
So here it refers to y intercept
y intercept (0,5)Hence
H(0)=5#b
Observe the graph
y intercept is not 0 so it's not true

[5,50]A consumer charges a $2,530.16 purchase on a credit card. the card has a daily interest rate of 0.042%. if the balance is paid off at the end of 30 days, how much interest will the consumer pay? a. $0.32 b. $3.19 c. $31.88 d. $318.78 please select the best answer from the choices provided a b c d
The consumer will pay $31.91 as an interest.
Initial balance = $2,530.16
Daily interest rate = 0.042%
What is simple interest?Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments
So, balance at the end of the first day = 2530*(1.00042)¹
balance at the end of the second day = 2530*(1.00042)²
Similarly, balance at the end of the 30th day = 2530*(1.00042)³⁰
Balance at the end of the 30th day = $2562.07291
So, interest levied = $2562.07291 - $2,530.16
Interest levied = $31.91
Therefore, the consumer will pay $31.91 as an interest.

pls helppppppppppppp
So I will be giving you the formula
[tex]a^{2} +b^{2} =c^{2}[/tex]
This [tex]c^{2}[/tex] is the hypothenuse which is opposite to 90 degrees
ill start from B
so [tex]a^{2}[/tex] and [tex]b^{2}[/tex] can be any side except the side opposite to 90 degrees it shouldn't change.
Answer for B with steps:
=> [tex]11^{2} +13^{2} =c^{2}[/tex]
=>simplify [tex]290=c^{2}[/tex]
=> get square root using your calculator [tex]\sqrt{290} =\sqrt{c^{2}[/tex]
=>the answer to B is 17.0 which is just 17
Answer for C
=>[tex]7^{2} +x^{2} =12^{2}[/tex]
=>[tex]49+x^{2} = 144[/tex]
=> subtract 49 on both sides 95 so its [tex]x^{2} = 95[/tex]
=> take square root [tex]\sqrt{x} ^{2} = \sqrt{95}[/tex]
=> Its 9.7

Help, what is the area of this figure? (Don’t write a big explanation!!, i really need this quick, a picture or just numbers u used is fine)
Answer:
146 m²
Area of triangle:
1/2 * base * height1/2 * 16 * 756 m²Area of upper rectangle:
Length * Width8 * 972 m²Area of bottom rectangle:
Length * Width6 * 318 m²Total area:
18 m² + 72 m² + 56 m²146 m²Answer:
146 m²
Step-by-step explanation:
Divide the figure into a triangle and 2 rectangles (see attached diagram)
Formulae
Area of a triangle = 1/2 x base x heightArea of a rectangle = width x lengthTriangle 1
⇒ area = 1/2 x 16 x (6 + 9 - 4 - 4)
= 1/2 x 16 x 7
= 56 m²
Rectangle 2
⇒ area = 3 x (6 + 9)
= 3 x 15
= 45 m²
Rectangle 3
⇒ area = 5 x 9
= 45 m²
Total area
⇒ Total area = triangle 1 + rectangle 2 + rectangle 3
= 56 + 45 + 45
= 146 m²

A hot air balloon travels 18 miles in 3 hours. At this rate, how many miles will it travel in 3/4 of an hour
Answer:
4.5 miles
Step-by-step explanation
Figure out how far the hot air balloon travelled in 1 hour - 3 hours can be divided by 3 for 1 hour, so do the same for the miles - 18 / 3 = 6
So basically, the hot air balloon travelled 6 miles in 1 hour.
Now, you can work out 3/4 of 6 for 3/4 of 1 hour - 3/4 * 6 = 4.5 miles
