Answer:
-20x+16 that is the answer
Step-by-step explanation:
Answer:
-20x +16
Step-by-step explanation:
As an equation because you cannot add a constant with a whole number so there is no one answer to you equation. How you can solve is you only need to add combine like terms and the 35 is a negative and not 15 minus 35 but 15x + (-35x). I hope this helps mate ;).

Solve the following inequality,
-3.559 S-284
Which graph shows the correct solution?
3 4 5 6 7 8 9 10 11 12 13
8 9 10 11 12 13
6710 11 12 13
347 90 11 12 13
Answer:
3rd option
Step-by-step explanation:
- 3.55g ≤ - 28.4
Divide both sides by - 3.55 , reversing the symbol as a result of dividing by a negative quantity
g ≥ 8
Since g is greater than or equal to 8 , then looking for a solid circle at g = 8 on the number line
Since g is greater than 8 then arrow pointing to the right from 8
This is shown on the third graph
Answer:
c is the correct answer

Write the sentence as an equation with x as the input, or independent variable, and y as the output, or dependent variable.
The output is six more than twice the input.
Answer:
y = 2x+6
Step-by-step explanation:
y is out
x is in
output = 6 more than twice the input
output = 6+2x
reorganize, 2x + 6
2x+6 = y
6x-3+1 when x=-3 and y= 2

Steve set up a business making friendship bracelets. He earned $70 in January. He is projected to earn 120% more in February. How much is Steve projected to make in February? PLS HELP!
$84
$98
$154
$190
Answer:
its 84 dollars sorry I'm late
Step-by-step explanation: Make a proportional relationship.
make 120% into a fraction. 120/100
then make 70 into a fraction using a variable. For example, x/70
Then cross multiply 120 and 70. 120x70=8,400
Last divide 8,400 by 100 and that equals $84.

Select the two binomials that are factors of
81x2 - 36
0 9x - 6
9x + 12
9x + 6
9x - 3
Factors are 9x-6 and 9x+6
=================================================
Explanation:
We use the difference of squares rule
m^2 - n^2 = (m-n)(m+n)
In this case we have
m = 9xn = 6So,
m^2 - n^2 = (m-n)(m+n)
(9x)^2 - 6^2 = (9x-6)(9x+6)
81x^2 - 36 = (9x-6)(9x+6)
Answer:
9x + 6 and 9x -- 6
Step-by-step explanation:
81x2--36 = (9x) 2 -- (6)2 = a2 -- b2 = (a+ b )(a--b) = (9x+6)(9x-6)
Which describes the graph of y = (x - 4)2 - 1?
-
A. Opens up with a vertex at (4,-1)
B. Opens down with a vertex at (4,-1)
C. Opens up with a vertex at (-4,-1)
D. Opens down with a vertex at (-4,-1)
C opens up with a vertex at (-4,-1)
Answer:
A
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
y = (x - 4)² - 1 ← is in vertex form
with vertex = (h, k ) = (4, - 1 )
• If a > 0 then the graph opens up
• If a < 0 then the graph opens down
Here a = 1 > 0 then graph opens up
Thus option A
Simplify -2(x - 5) + 4(9 + x).
Step-by-step explanation:
= -2(x - 5) + 4(9 + x)
= -2x + 10 + 36 + 4x
= (-2 + 4)x + 10 + 36
= 2x + 46
Estimate 11.92 x 3.21
11.92 × 3.21 = 38.2632
Answer:
-If you need to round to the whole number, you would round down to 38
-If your answer needs to be a decimal, it would be 38.30
If you don't have a specific way you need to round it, estimates are usually whole numbers, so your answer would be 38

two numbers that multiplied together give me 10 and the difference of the two numbers is -2?
Answer:
10/(1+√11), 1+√11 and 10/(1-√11) and 1-√11
Step-by-step explanation:
Let x be the first number and y the second number
two numbers that multiplied together give me 10
x*y = 10
and the difference of the two numbers is -2?
x-y = -2
we can write x in terms of y so we only have one variable y
x-y =-2 , add y to both sides
x-y+y = y -2, combine like terms
x= y-2
x*y = 10, substitute x=y-2
(y-2)y = 10, distribute in parenthesis
y² -2y-10 = 0, subtract 10 from both sides
We can use the quadratic formula to solve y² -2y-10 = 0
y = (-b±√b²-4ac)/2a, where a= 1, b= -2, c= -10
y = (2±√4+4*1*10)/2
y = (2±√44)/2
y= (2±2√11)/2
y= 1±√11
x*y = 10, divide both sides by y
x= 10/y
x= 10/(1±√11)
Check :
x*y = 10
[10/(1±√11)] * (1±√11) = 10
⇒[10/(1+√11)] * (1+√11) = 10✅
⇒[10/(1-√11)] * (1-√11) = 10✅
⇒[10/(1+√11)] * (1-√11) = 10❌
⇒[10/(1-√11)] * (1+√11) = 10❌
x-y = -2
⇒
[10/(1+√11) ] -(1+√11) =
[10 -(1+√11 )(1+√11 )]/ (1+√11 ) =
[10 - (1+11+2√11)]/ (1+√11) =
(10-12 -2√11) / (1+√11) =
(-2 -2√11) / (1+√11) =
-2(1+√11)/ (1+√11) =
-2 ✅
⇒
[10/(1-√11) ] -(1-√11) =
[10 -(1-√11 )(1-√11 )]/ (1-√11 ) =
[10 - (1+11-2√11)]/ (1-√11) =
(10-12 +2√11) / (1-√11) =
(-2 +2√11) / (1-√11) =
-2(1 -√11)/ (1-√11) =
-2 ✅

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
Part B
How many feet apart are the two ocean elevations described in part A?
Part C
What is the elevation of the deck where Winston ate dinner?
Part D
What is the elevation of the surf shop?
Part F
What was the distance between the surf shop and the ocean’s surface at 7 p.m.? Which was higher, the surf shop or the ocean?

Answer:
The answer would be Part F
The distance that you travel at a constant speed varies directly with the time spent traveling. It takes you 2 h to travel 100 mi. Write an equation for the relationship between time and distance. How far would you travel in 3.5 h?
100 miles is the distance we know traveled in 2 hours. Therefore we can make this equation:
100 = 2x
100 / 2 =x
50 = x
We travel 50 miles an hour.
Now we know the x, 3.5 so lets plug that in:
3.5x = y
3.5(50) = y
175 = y
Therefore we travelled 175 miles in 3.5 hours.
I hope this helps! :)
Answer:
The speed is distance / time and speed times time equals distance
Step-by-step explanation:
speed = 100/2=50 mi/hr
distance =f(t)=50t
f(3.5)=50×3.5=175miles
hope that helps

The length of a rectangle is 6 inches longer than its width. The perimeter of the rectangle is 28 inches. If x represents
the width of the rectangle in inches, which equation can be used to find its value?
Answer:
Width = 4
Length = 10
Step-by-step explanation:
Width: x
Length: x+6
2x + 2(x+6) = 28
2x + 2x + 12 = 28
4x = 28-12
x = 16/4
x = 4

What is an equation of the line that passes through the points (-3, -1) and (6, 2)
Answer:
y = 1/3x
Step-by-step explanation:
Using the slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
Taking (-3,-1) as (x1,y1) and (6,2) as (x2,y2):
(2-(-1))/(6-(-3))
= (2+1)/(6+3)
= 3/9
= 1/3
Hence, the slope (m) is 1/3
Substituting the slope into 'y = mx+c':
y = 1/3x + c
Substituting any point, however, we will be substituting (-3,-1):
-1 = 1/3 * (-3) + c
-1 = -1 + c
c = -1 + 1
= 0
Hence,
y = 1/3x
