= x2 + 5x – 4x – 20
= x2 + x - 20
4= a/7 - 4 can anyone help find a ?
Answer:
A = 28
Step-by-step explanation:
You would multiply by 7 on both sides. You multiply by 7 on the right to get rid of the fraction, so you are just left with A on the right. Then you multiply on the left, so it would be 4x7, which equals 28. A=28.
Answer:
56 =a
Step-by-step explanation:
4 = a/7 -4
Add 4 to each side
4+4 = a/7 -4+4
8 = a/7
Multiply each side by 7
8*7 =a/7*7
56 =a

Answer:
a- (x-7)(x+9) | b- 193*207 | c- 242*258
Step-by-step explanation:
a)
x^2+2x-63.
the middle number is 2 and the last number is -63.
You would have 2 numbers that add to 2 and multiply to -63.
Those numbers are -7 and 9.
so (x-7)(x+9).
b)
((200)-7)((200)+9)
(193)(209).
You can check this by multiplying 193 by 209 and then doing (200)^2+2(200)-63. Both would equal 40337.
c)
2(x-7)+2(x+9)=1000
(2x-14)+(2x+18)=1000
4x+4=1000
4x=996
x=249.
((249)-7)((249)+9)
(242)(258)

Jada bought some sugar and strawberries to make strawberry jam. Sugar costs $1.80 per pound, and strawberries cost $2.50 per pound. Jada spent a total of $19.40. Which point on the coordinate plane could represent the pounds of sugar and strawberries that Jada used to make jam? Graph of a line - sugar(pounds) on horizontal axis and strawberries (pounds) on vertical axis Group of answer choices Point A Point B Point C Point D
Answer:X + Y ≥ 4
$2.20X + $2.95Y ≤ $10.00
Strawberries cost $2.20 per pound
Raspberries cost $2.95 per pound
Jada only has $10.00 to spend
She wants to buy at least 4 pounds
Assumption: She buys X pounds of strawberries and Y pounds of raspberries.
Solution:
Number of pounds can't be less than 4
i.e X + Y ≥ 4
The cost of buying strawberries and raspberries has to be $10.00 or less than $10.00
i.e $2.20X + $2.95Y ≤ $10.00
So the system of equations is;
X + Y ≥ 4
$2.20X + $2.95Y ≤ $10.00

QUESTION 4
A test was administered in a health class. The scores have a mean of 75 with a standard deviation of 4.8. Pat scored an 83 on the test. How
does Pat's score deviate from the mean on the standard scale?
Answer:
Pat's score is 1.67 standard deviation above the mean
Step-by-step explanation:
We solve using z score formula
z score tells us how much a score deviates from the mean
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
x = 83
μ = 75
σ = 4.8
z score = 1.66667
Therefore, Pat's score is 1.67 standard deviations above the mean

what are the coordinates of the vertex in f(x) = -4(x+3)^2-8
Answer:
vertex = (- 3, - 8 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = - 4(x + 3)² - 8 ← is in vertex form
with (h, k) = (- 3, - 8 ) ← vertex

Answer:
If she is 120 feet below the surface she is -120 feet below the surface. If she goes up by 83 feet she will be 37 feet below the surface. Therfore the answer is -37 feet.
The current dept is 37 feet below the water surface.
What is negative sign?
A negative sign or minus sign is a mathematical symbol to represents the subtraction between to numbers. It is also used to represent a negative numbers.
The negative or minus sign also indicates movement in the opposite direction on a number line.
According to the given question
Scuba diver is 120 feet below the water surface.
On number line 120 feet below is represented by -120.
She ascends 83 feet means , she goes up 83 feet up
So, the current depth is calculated as
-120feet + 83feet
= -37 feet.
The negative sign represent that Scuba is 37 feet below the water surface.
Hence, the current dept is 37 feet below the water surface.

Taylor works at a garden shop that sells flower pots. One kind of flower pot has a rim height of 6 centimeters and a planting height of 22 centimeters. Taylor begins to stack the flower pots as shown.
The table shows the height of each stack for the given number of flower pots.
Number of Flower Pots, n 1 2 3 4 5
Height of Stack in cm 28 34 40 46 52
Write a simplified algebraic expression to represent the height of a stack of n flower pots.
Answer:
The simplified algebraic expression to represent the height, h, of a stack in cm of n flower pots is h = 6·n + 22
Step-by-step explanation:
The given information are;
The rim height of one kind of flower pot = 6 cm
The planting height of the flower pot = 22 cm
Therefore, the total height of the flower pot = 22 + 6 = 28 cm
Stacking the flower pots of a single kind will give a linear relationship of the form, y = m·x + c between the height of the stack and the number of flower pots in the stack
Where;
m = The slope or the rate of change of the height with the number of flower pots in a stack which can be found from two points in the given table of values
c = The y-intercept or height at the start of the first stack
From the table of values, for the first and the last points, we have;
m = (52 - 28)/(5 - 1) = 24/4 = 6
Which gives;
h - 52 = 6×(n - 5)
h = 6·n - 30 + 52 = 6·n + 22
h = 6·n + 22
Where;
h = The height of stack in cm
n = The number of flower pots
Therefore, by comparing to the general form of the equation of a straight line, y = m·x + c, the y-intercept, c = 22
The simplified algebraic expression to represent the height of a stack of n flower pots is therefore given as h = 6·n + 22.

Subtract 6 from every number
Answer:
We subtract 6 each time
-22,-28,-34
Step-by-step explanation:
8,2,-4,-10,-16
8-2 = 6
We subtract 6 each time
2-6 = -4
-4-6 = -10

-16-6 = -22
-22-6 = -28
-28-6 = -34

A veterinarian is changing the diets of two animals, Simba and Cuddles. Simba currently consumes 1,520 Calories per day. That number will increase by 130 Calories each day. Cuddles currently consumes 3,380 Calories a day. That number will decrease by 180 Calories each day. The patterns will continue until both animals are consuming same number of Calories each day. In how many days will that be? How many Calories will the animals be consuming each day then? In days Simba and Cuddles will be consuming the same amount of calories. Simba and Cuddles will be consuming calories each day.
Answer:
6 days ; 2300 calories
Step-by-step explanation:
Given the following :
Current consumption :
Simba = 1520 calories per day
Increases by 130 calories per day : After d days ;
S(d) = 1520 + 130d
Where ; d = number of days
Cuddle = 3380 calories
Decreases by 180 calories each day; after d days ;
S(d) = 3380 - 180d
Pattern continues until they both consume same number of calories each day
S(d) = C(d)
1520 + 130d = 3380 - 180d
130d + 180d = 3380 - 1520
310d = 1860
d = 6
Number of calories they will be consuming them ;
Using : S(d) = 3380 - 180d
S(6) = 3380 - 180(6)
S = 3380 - 1080
S = 2300
They will be consuming 2300 calories by then.
