Answer:
[tex]1. 3x+21 = 6x-60\\or, 6x-3x = 21+60 [Being~corresponding~angles]\\or, 3x = 81\\or, x = 27.\\Equations: 3x+21=6x-60\\Value ~of ~x = 27\\Angle ~measure = (3x+21), (6x-60) = 3(27)+21,6(27)-60 = 102,102\\[/tex]
[tex]2. 12x - 18 = 8x+10 [Being~vertically~opposite~angles]\\or, 12x - 8x = 18+10\\or, 4x = 28\\or, x = 7\\Equations: 12x-18 = 8x+10\\Value~ of~ x: 7\\Angle ~measure: (12x-18),(8x+10) = 66,66\\[/tex]
[tex]3. Have~a~look~at~the~figure.\\Here, y = 3x+9 [Being~ vertically ~opposite ~angles]\\Also, y+5x+3 = 180^{o} [ Being~cointerior~angles]\\or, 3x^{o}+9^{o}+5x^{o}+3^{o}=180^{o}\\or, 8x^{o}+12^{o}=180^{0}\\or, 8x^{o} = 168^{o}\\or, x = 21^{o}\\So, 3x+9 = 3(21)+0 = 72^{o} ~and ~5x+3 = 5(21)+3 = 108^{o}\\Equations: y = 3x +9, y+5x+3=180^{o}\\Value ~of~ x: 21^{o}\\Angle ~measure: 72^{o},108^{o}[/tex]

Answer: f(3) = g(3)
Step-by-step explanation:
ok so f and g are unknown numbers and 3 is equal to 3, since f and g are unknown they could be any number so that's why there the same.
Answer:
f(3) > g(3)
Step-by-step explanation:
add 3 into each equation.
f(x) = 4x^4 g(x) = 10 * 2^x
= =
f(3) = 4(3)^4 g(3) = 10 * 2³
Solve each equation.
f(3) = 4(3)^4 g(3) = 10 * 2^3
= =
f(3) = 12^4 g(3) = 20^3
= =
f(3) = 20,736 g(3) = 8,000
f(3) is greater than g(3)
f(3) > g(3)

(explain answer) Helpp pleasee!! asap
Answers
Answer:
x = 30 degrees
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the alternate corresponding angles are supplementary, meaning their degree measures add up to 180. One can apply this here by stating that the two given angles add up to 180. Then one can simplify and use inverse operations to solve for (x).
(6x - 5) + (x - 25) = 180
6x - 5 + x - 25 = 180
7x - 30 = 180
+30 +30
7x = 210

x = 30
x=30 i hope this helped

Will the graph of the line represented by the table intersect the graph of y = 5x + 4? Explain.A table showing data of x and y as (-2,5), (-1,0), (0,5), (1,10) and (2,15) respectively.
Answers
Answer:
you'll need to identify the equation of the line represented in the table. By plugging in coordinates given in the table, it's possible to identify the slope and y-intercept of the line.
Step-by-step explanation:
Yes, the lines intersect each other.
What is slope?
The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given that, a table of points (-2,5), (-1,0), (0,5), (1,10) and (2,15) and a line
y = 5x + 4
Finding the slope of the line represented by the given points,
slope = (y₂-y₁)/(x₂-x₁)
Considering the points (-2,5) and (-1,0)
Slope = (0-5)/(-1+2) = -5/1 = -5
And the slope of the line y = 5x + 4 is 5
We know that, If they have different slopes and different y-intercepts, they will meet at a point.
Hence, the lines will intersect.

Miles bought a new pair of baseball cleats for $64.95. The sales tax is 6.5%. What is the total cost that Miles will pay?
Answers
Answer: $69.17175
Step-by-step explanation:
The cleats are $64.95. Tax is a percentage taken off certain goods so
6.5% of $64.95 which can be also restructured as 6.5/100 times $64.95 which is $4.22175. Tax is added onto the final cost so he shall pay $64.95 plus $4.22175. (I think)
