find the values if a and b such that x squared + 2x -7 = (x+a) squared + b
Given:
[tex]x^2+2x-7=(x+a)^2+b[/tex]
To find:
The values of a and b.
Solution:
We have,
[tex]x^2+2x-7=(x+a)^2+b[/tex]
It can be written as
[tex](x^2+2x)-7=(x+a)^2+b[/tex]
Add and subtract square of half of coefficient of x in the parenthesis.
[tex](x^2+2x+(\dfrac{2}{2})^2-(\dfrac{2}{2})^2)-7=(x+a)^2+b[/tex]
[tex](x^2+2x+1^2)-1-7=(x+a)^2+b[/tex]
[tex](x+1)^2-8=(x+a)^2+b[/tex] [tex][\because (x+y)^2=x^2+2xy+y^2][/tex]
[tex](x+1)^2+(-8)=(x+a)^2+b[/tex]
On comparing both sides, we get
[tex]a=1[/tex]
[tex]b=-8[/tex]
Therefore, the value of a is 1 and the value of b is -8.
A speed skater travels how many meters per second?
Answer:
In skating, one skate pushes and the other skate glides--there is very little friction to slow you down. Speed skater Hiroyasu Shimizu of Japan can travel 500 meters in just 35.39 seconds, an average speed of 14.13 meters per second or 31.6 miles per hour.

The phases of the moon are caused by:
A) tilt of the earth
b) tilt of the moon
c) revolution of the earth around the sun
d) revolution of the moon around the earth
Answer:
The moon's phases are caused by the changing angles of the earth's shadows and reflected sunlight as the moon revolves around the Earth over the course of about 1 month (28 days). An imaginary line where the Earth is tilted.
Answer:
b. tilt of moon
Step-by-step explanation:
it would be the same reason we get our season because the moon is not directly on its vertical axis
Solve |x + 1| = 3 Question 12 options: A) x = 3 or x = 2 B) x = 4 C) No solutions D) x = –4 or x = 2
Answer:
x=2
x=-4
Step-by-step explanation:
[tex] |x + 1| = 3[/tex]
[tex]x + 1 = 3 \\ x + 1 = - 3[/tex]
therefore
[tex]x = 2 \\ x = - 4[/tex]
18 divide by 2 * 3/5-2 simplify show all work
Answer:
9
Step-by-step explanation:
I would guess it looks like this - if not then tell me
[tex] \frac{18}{ \frac{2 \times 3}{5 - 2} } [/tex]
2×3=6
5-2=3
Then there's only
[tex] \frac{18}{ \frac{6}{3} } [/tex]
Which is equal to
[tex] \frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9[/tex]
Answer:
9 or 3 2/5Step-by-step explanation:
There are two scenarios, (5 - 2) in denominator and 5 in denominator as it is not clear. Solving both:
18/2*3/(5 - 2) =9*3/3 = 9*1 =9------------------------
18/2*3/5 - 2 =9*3/5 - 2=27/5 - 2 =17/5 =3 2/5If [tex]\sf a = log_92[/tex] and [tex]\sf b = log_54[/tex], find [tex]\sf log_615[/tex] in terms of a and b.
Answer:
(4a + b)/(2ab + b)Step-by-step explanation:
Givena = log9 2b = log5 4To findlog6 15 in terms of a and bSolutionRewrite the given
log9 2 = a ⇒ log2/log9 = a ⇒ 1/2*log2/log3 = a ⇒ log3 = 1/2*log2/alog5 4 = b ⇒ log4/log5 = b ⇒ log5 = 2*log2/bRewriting the log6 15:
log6 15 = log15/log6= (log 5 + log3)/(log2 + log3)Substitute as follows:
(log 5 + log3)/(log2 + log3) =(2*log2/b + 1/2*log2/a)/(log2 + 1/2*log2/a) =(2/b + 1/(2a))/(1 + 1/(2a)) =(4a + b)/2ab ÷ (2a + 1)/2a =(4a + b)/(2ab + b)What term best describes the expression x + 3?

can someone please help....please & thank you.
Answer:
C
Step-by-step explanation:
Answer:
1. m<13
2. x≥1
3. p>-3
Step-by-step explanation:
1. m-7<6
Add seven to both sides
m<13
2. x+4.5≥5.5
subtract 4.5 from both sides
x≥1
3. p+12>9
subtract 12 from both sides
p>-3

WILL MARK BRAINLY! The population of a particular city is given by the function P(t) = 82,100(1.02), where t is the time in years and P(t) is the population after t years. What is the current population, the percentage growth rate, and the population size (rounded to the nearest whole person) after 15 years?
Hint: Percentage Growth Rate = r × 100 in A= A0(1 + r)^t
○ 82,100, 2% semiannually, 110,658
○ 82,100, 10.2% annually, 352,425
○ 82,100, 2% annually, 110,496
○ 82,100, 20% semiannually, 985,200
Answer:
P(t) = 82,100(1.02)^t
1.t is the time in years
2.P(t) is the population after t years
3. 100%=1 102-100=2% so the interest rate is 2 %
102%=1.02

Ann has to make payments twice a year on her health insurance. If each payment is $2,316, how much money should she budget for health insurance each month? Round to the nearest dollar. A. $579 B. $386 C. $1,158 D. $193
Answer:
$386
Step-by-step explanation:
If Ann has to pay $2316 twice a year
(every 6 months), then, we calculate
$2316/6 = $386 every month.
Hence, Ann's budget for health
insurance each month is $386.

Answer:
Choice D: not possible

The reason why it's not possible is that when you try to make an equation it never comes out correct. You could also try plugging in the numbers then figure it out that way. It's not possible either way you do it.

Josh is ordering an ice cream dessert. He must order a size, a flavor of ice cream, and a topping. There are 3 sizes, 2 flavors, and 2 toppings to choose
from. How many different ice cream desserts could he order?
Step-by-step explanation:
So if there are 3 sizes, 2 flavors and 2 Toppings to choose from, then there are
3 * 2 * 2 possible combinations
For example:
S = 3 sizes
F = 2 flavours
T = 2 toppings
Then there are 3 * 2 * 2 = 12 possible combinations
Rachel and David were shopping for holiday gifts when they noticed a Thanksgiving sweater on the discount rack. Rachel really wanted the sweater, even though she wouldn’t be wearing it until Thanksgiving of 2021! Part A: If the original price of the sweater was $24.00, and the sweater is on sale for 60% off, what is the sale price?
Answer:
[tex]Sales\ Price = \$9.60[/tex]
Step-by-step explanation:
Given
[tex]Price = \$24.00[/tex]
[tex]Discount = 60\%[/tex]
Required
Determine the sales price
First, we calculate the discount price
[tex]Discount\ Price = Price * Discount[/tex]
[tex]Discount\ Price = \$24.00 * 60\%[/tex]
[tex]Discount\ Price = \$14.4[/tex]
The sales price is then calculated by subtracting the discount price from the original price of the item
[tex]Sales\ Price = Price - Discount\ Price[/tex]
[tex]Sales\ Price = \$24.00 - \$14.40[/tex]
[tex]Sales\ Price = \$9.60[/tex]

x-7y= -49 (ANSWER?)
Answer:
[tex]y = \frac{1}{7} x + 7[/tex]
Step-by-step explanation:
x-7y = -49
i) move x to the right-hand side and change its sign
-7y = -49-x
ii) change the signs on both sides of the equation
7y = 49+x
iii) divide both sides of the equation by 7
[tex] \frac{7y}{7} = \frac{49}{7} + \frac{x}{7} [/tex]
[tex]y = 7 + \frac{1}{7} x[/tex]
iv) use the commutative property to reorder the terms
* commutative property: a+b = b+a
[tex]y = \frac{1}{7} x + 7[/tex]
