Can I please get help with the Answer
Answer:
56
Step-by-step explanation:
Answer:
B = 56
Step-by-step explanation:
A + B = 90 degrees
(6x - 8) + (5x + 21) = 90
6x - 8 + 5x + 21 = 90
(6x + 5x) + (-8 + 21) = 90
11x + 13 = 90
11x + 13 - 13 = 90 - 13
11x = 77
11x/11 = 77/11
x = 7
Plug into (5x + 21).
5(7) + 21 =
35 + 21 = 56
B = 56
Identify all of the roots of the function f(x) = x^3 - 5x^2-2x+24
The roots are -2, 3 and 4.
What are roots?A solution to an equation, usually expressed as a number or an algebraic formula.
Given:
x³-5x²-2x+24
As, x+2 divides the x³-5x²-2x+24 gives quotient x²−7x+12.
Now,
x²−7x+12.
=x²− 4x -3 x+12.
=x(x-4) - 3(x-4)
=(x-4)(x-3)
Hence, the roots are -2, 3 and 4.

A pool estimate that 43% of likely voters are in favor of additional restrictions on teen drivers the Poll has a margin of error of plus or minus 4%. Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Estimated number of voters in favor of additional restriction = 43%
Margin of Error = ±4%
Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:
Minimum percentage of voters = 4% lesser than the estimated number of voters
Maximum percentage of voters = 4% greater than the estimated number of voters
Let number of voters = v
|v - 43%| = ±4%
v = - 4% + 43% = 39% = minimum percentage
v = +4% + 43% = 47% = maximum percentage
39% ≤ v ≤ 47%

Step-by-step explanation:
Samir begins riding his bike at a rate of 6 miles per hour. Twelve minutes later, Chris leaves from the same point and bikes along the same route at 9 miles per hour. How long after Chris begins riding does he catch up to Samir? 4 min 12 min 24 min 40 min
Answer:
The correct option is C) 24 min.
Step-by-step explanation:
It is given that:
Speed of Samir riding his bike = 6mph
Speed of Chris riding his bike = 9 mph
Let the time taken by Chris be x min. Then the time was taken by Samir be x+12
We know that the formula for the distance is
Where d is the distance, t is the time and r is the rate.
According to the question:
[tex]9x=6(x+12)\\9x=6x+72\\9x-6x=72\\3x=72\\x=24[/tex]
Hence, after 24 minutes Chris will catch up to Samir.
Therefore the correct option is C) 24 min.

For questions 18-20, if l \\ m, find the values of x and y
Answer:
Step-by-step explanation:
18). l║m and a transverse is intersecting these lines.
(11y - 32)° = (6x + 7)° [Vertical angles]
-6x + 11y = 39 -------(1)
(3x - 16)° + (6x + 7)°= 180° [Same side exterior angles]
9x - 9 = 180
9x = 189
x = 21
Now substitute the value of x in the equation (1)
-6(21) + 11y = 39
11y = 39 + 126
y = 15
19). l║m and a transversal is intersecting these lines.
(8x - 14)° + (5y + 16)° = 180° [Linear pair of angles]
8x + 5y = 178 --------(1)
(8x - 14)° = (5x + 34)° [Alternate exterior angles]
8x - 5x = 48
3x = 48
x = 16
From equation (1)
8(16) + 5y = 178
128 + 5y = 178
5y = 178 - 128
y = 10
20). From the figure attached,
m∠CAB = (5y - 23)°
Since sum of interior angles of a triangle is 180°
m∠CAB + m∠ACB + m∠ABC = 180°
(5y - 23)° + (2x + 13)° + (47)° = 180°
2x + 5y = 143 ------(1)
(5y - 23)° = 3x°
3x - 5y = -23 -----(2)
Equation (1) + Equation (2)
(2x + 5y) + (3x - 5y) = 143 - 23
5x = 120
x = 24
From equation (1)
2(24) + 5y = 143
48 + 5y = 143
5y = 95
y = 19

c.The slope is 2, and the y-intercept is 6.
d.The slope is 2, and the y-intercept is 12.
Answer:
b
Step-by-step explanation:
the y intercept is at 12 and it slopes down
Answer:
B. the slope is -2, and the y-intercept is 12.
Step-by-step explanation:
i cant really explain stuff that well but basically you have to find the slope. you have to subtract 18-12 and you would get 6. then subtract -3-0 and that would be -3.
you then have to divide 6 (-3) and you would get -2. i never knew how to get 12 tho- sorry lol
Graph the line with the equation y = x + 6.
Answer:
Hi there!
Your answer is:
Based off the equation we know that the slope is 1 and the y intercept is 6. We know that slope is rise/run so it goes UP one unit for every unit it goes RIGHT! We must start at the point (0,6) because that is the y intercept
Question on a picture
Answer:
c = 0
Step-by-step explanation:
Step 1: Write equation
15 - 5(4c - 7) = 50
Step 2: Solve for c
Distribute -5: 15 - 20c + 35 = 50Combine like terms: -20c + 50 = 50Subtract 50 on both sides: -20c = 0Divide both sides by -20: c = 0Step 3: Check
Plug in c to verify it's a solution.
15 - 5(4(0) - 7) = 50
15 - 5(-7) = 50
15 + 35 = 50
50 = 50
