Answer:
5
Step-by-step explanation:
get the equation into slope intercept form, y = mx +b
where b is the y-intercept
subtract x from both sides
7y = -x + 35
divide 7 from both sides
y = -1/7 x + 5
thus b = 5

Answer: 3234 cubic units
Step-by-step explanation:
Volume of cylinder: πr²h
The diameter of the cylinder is 14 units so the radius is 7 units.
Now we'll substitute.
π = 22/7
h = 21
πr²h
π × 7² × 21
22/7 × 49 × 21 = 3,234
The volume is 3,234 cubic units.

What is the slope of the equation y = 5x – 7?
A. 32
B. 23
C. 3
D. 2
find the y intercepts I'll mark the brainliest
Answer:
1. (0,-2)
2. (0,8)
3. (0,7)
4. (0 , [tex]\frac{1}{2}[/tex])
5. (0,-3.5)
6. (0,-4)
7. (0,0)
8. (0,-4)
9. (0,5)
10. (0,0)
Step-by-step explanation:
there are 10 boxes in total, slope is y = mx + b
the slope is always the constant.
constant: number without a variable.
y - intercept:
y = mx + b
if there is nothing after the slope it means the y -intercept is 0

Isaiah is working two summer jobs, making $16 per hour tutoring and $10 per hour clearing tables. Isaiah must earn at least $110 this week. Write an inequality that would represent the possible values for the number of hours tutoring, tt, and the number of hours clearing tables, cc, that Isaiah can work in a given week.
Answer:
16t + 10c > 110
Step-by-step explanation:
Cost of tutoring per hour = $16
So, cost of tutoring t hours = $16t
Cost of clearing tables per hour = $10
So, cost of clearing tables c hours = $10c
Since, Isaiah must earn at least $110 this week.
Therefore, the required inequality will be given as:
16t + 10c > 110
Solve the expression (-3) (-2)(3)(4)

Sushi was thinking of a number. Sushi doubles it,then adds 20 to get an answer of 27.7 what was the original number
Answer:
3.85
Step-by-step explanation
7.7 divided by 2 = 3.85
So if you double 3.85 you get 7.7 and then add 20 to 7.7 then you get 27.7
Let the number they are thinking of be X.
They double x , which would be 2x.
They then add 20, which would be 2x +20
So you have 2x + 20 = 27.7
Now we can solve for x:
Subtract 20 from both sides:
2x = 7.7
Divide both sides by 2:
x = 7.7 / 2
x = 3.85
The original number was 3.85

9(x - 2) = 7x + 5 a) true for all values of x b) true for one value of x c) true for no values of x
Answer:
b) true for one value
Explanation:
If you solve for x, there is only one value of x
Answer:
(b)
Step-by-step explanation:
9(x - 2) = 7x + 5 ← distribute left side
9x - 18 = 7x + 5 ( subtract 7x from both sides )
2x - 18 = 5 ( add 18 to both sides )
2x = 23 ( divide both sides by 2 )
x = [tex]\frac{23}{2}[/tex]

Answer:
What is the value of x?
x = 40 degrees.
What is the measure of angle AFE?
Angle AFE = 140 degrees
What is the measure of angle BFD?
Angle BFD = 140 degrees.
Step-by-step explanation:
Angle AFC is 90 degrees.
To find angle x, we have to subtract angle BFC.
90 - 50 = 40 degrees.
Line BFE is 180 degrees.
To find angle AFE, we have to subtract angle x from 180 degrees.
We have solved x already.
180 - 40 = 140 degrees.
Angle BFD is just 90 degrees plus 50 degrees.
90 + 50 = 140 degrees.
Answer:
x = 40
m<AFE = 140
m<BFD = 140
Step-by-step explanation:
1. Finding X
As one can see, AD is a straight line (hence the three angles that add up to is equal 180 degrees). It is given that m<CFD is 90 degrees (signified by the box).
Given;
AD - straight line
m<AFB + m<BFC + m<CFD = 180
( m<AFB, m<BFC, m<CFD form line AD, the degree measures in al ine equal 180, hence m<AFB + m<BFC + m<CFD = 180)
m<BFC = 50
m<CFD = 90 (signified by box around it)
m<AFB + m<BFC + m<CFD = 180 parts whole postulate
x + 50 + 90 = 180 substitution
x + 140 = 180 algebra
x = 40
2. Finding m<AFE and m<BFD
When two straight lines intersect, four angles are formed. The angles that are opposite to each other are called vertical angles, and vertical angles are congruent in other words, have the same measure.
Given;
m<BFD = m< AFE
m<BFC + m<CFD = m<BFD
m<BFC = 50
m<CFD = 90
m<BFC + m<CFD = m<BFD Given (parts whole postulate)
50 + 90 = m<BFD substitution
140 = m<BFD algebra
140 = m<BFD = m<AFE substition

An arithmetic sequence has this explicit formula: an = 14 + (n - 1)3. What is the recursive formula?
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 with a₁ = 14
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference, then
[tex]a_{n}[/tex] = 14 + (n - 1)3
has a₁ = 14 and d = 3
A recursive formula allows a term in the sequence to be found by adding d to the previous term, thus recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 , with a₁ = 14
