Answer:
D
Step-by-step explanation:
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.
how do i do this pls help me

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]

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

A can of green spray paint is held upright 8 inches away from a wall. The nozzle on the
spray paint creates an angle of 50° as it spreads paint out. When the paint lands on the
wall (as the can is held steady) it makes the shape of a circle. What will the approximate
area of the circle be? Round your answer to the nearest hundredths of a square inch.

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
4. after 15 year just put in term s of 't' (wich is represent the years) 15 :

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 2/5Jamie earns $36 for 4 hours of work. What is her hourly pay rate?

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
Researchers compare the body composition of cattle feeding on a grain diet with that of cattle feeding on a grass diet. This method of gathering data is classified as
a census.
a sample survey.
an experiment.
an observational study.
d is ur answer⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Answer:
The answer is D. An observational study
Step-by-step explanation:
The researchers are observing how different diets in the cattle affects their body composition. They are not counting a population or anything so it is not a census. It is not a sample survey because they aren't asking cows and it is not an experiment because they are not changing or testing anything. They are just viewing meaning it is an observational study.
your answer is D. Observational Study on 3dgenuity

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

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:
The solution is (2, 1).
All other ordered pairs do not work.
Step-by-step explanation:
-2x + 5y = 1
5x - 3y = 7
-10x + 25y = 5
10x - 6y = 14
19y = 19
y = 1
5x - 3(1) = 7
5x = 10
x = 2
(2, 1)
The solution is (2, 1).
All other ordered pairs do not work.

Attend to precision. Suppose that ∠1 and ∠2 are same-side interior angles formed by two parallel lines cut by a transversal, and that m∠1=7x-4 and m∠2=20x-5.
a.What is the value of x?
b.What is m∠1?
c.What is m∠2?
d.Explain how you found your answers.
9514 1404 393
Answer:
a) x = 7
b) m∠1 = 45°
c) m∠2 = 135°
Step-by-step explanation:
a) Same-side interior angles are supplementary, so we have ...
∠1 +∠2 = 180
(7x -4) +(20x -5) = 180
27x = 189
x = 7
__
b) The measures of the angles can be found by substituting the value of x into the express for the angle measure.
m∠1 = 7x -4 = 7(7) -4 = 45
m∠1 = 45°
__
c) Angle 2 is the supplement of angle 1, so ...
m∠2 = 180° -45°
m∠2 = 135°
__
d) We used the relationship of angles at a transversal and the properties of equality.
