Answer:
A. x=8 y=21
Step-by-step explanation:
line l and line m are parallel, and both angles that have x in the values are on the same side, so they are equal to each other.
7x+12=12x-28
+28 +28
7x+40=12x
-7x -7x
40=5x
/5 /5
8=x
Since A is the only choice that has x=8, it must be the right answer.
Answer:
x = 8, y = 21
Step-by-step explanation:
parallel means they're equal so..
7x + 12 = 12x - 28
-7x -7x
12 = 5x -28
+28 +28
40 = 5x
8 = x
plug in 8 to 12x - 28
12(8) - 28
96 - 28 = 68
180 - 68 = 112
9y - 77 = 112
+77 +77
9y = 189
y = 21

THE LENGTH AND THE BREADTH OF A RECTANGULAR PARK ARE IN THE RATIO 5 : 2. IF ITS PERIMETER IS 168m, FIND ITS LENGTH AND BREADTH.
(STEP BY STEP PLZ) (HOPE U ENJOY IT)
Answers
Answer:
Length = 60m, breadth = 24m
Step-by-step explanation:
Let the length of the park be 5x and the breadth 2x.
5x+5x+2x+2x = 168
14x = 168
x = 168 ÷ 14
x = 12
Length (5x) = 12 × 5
= 60
Breadth (2x) = 12 × 2
= 24
Answer:
Length = 60m, breadth = 24m

12) 15 increased by [tex]66\frac{2}{3}[/tex]%
13) $9,450
14) $149.8
15) $238.5
Step-by-step explanation:
10) 170 is greater than 150 by 25. 25 is [tex]16\frac{2}{3}[/tex]% of 150, so it increased by appoxamately 17%.
11) 225 is decreased by 45. 45 is 20% of 100, so 255 decreased by 20%
12) 15 is increased by 10. 10 is [tex]66\frac{2}{3}[/tex] of 15, so 15 increased by [tex]66\frac{2}{3}[/tex]%
13) 5% of 9,000 is 450. 450 + 9,000 is $9,450
14) 7% of 140 is is 9.8. 140 + 9.8 = $149.8
15) 6% of 225 is 13.5. 225 + 13.5 = $238.5

how do solve slope and for the y axis?
Answers
Answer:
Slope = rise/run or y2-y1/x2-x1 (change in y over change in x)
Y-intercept (I'm assuming you mean y-intercept instead of y axis) = if there's a graph, find where the line intersects the y axis, if there isn't a graph, use y=mx+b to solve for b, the y-intercept.

For moving object the force acting on the object varies directly with the object acceleration when a force of 36 in acts on a certain object the acceleration of the object is 6 m/s squared if the force is changed to 24 in what will be the acceleration of the object
Answers
Answer:
4m/s²
Step-by-step explanation:
Given that:
Force F is directly proportional to acceleration a
F α a
F = ka
Where k is the constant of proportionality
36 = 6k
Solve for K
36 = 6k
k = 36/6
k = 6
If force = 24 ; acceleration =
24 = ka
k = 6
24 = 6a
a = 24/6
a = 4m/s²

Answers
Answer:
45
Step-by-step explanation:
Replace everything in the equation that has a x to -3:
f(-3)=3(-3)^2-4(-3)+6
Square the -3:
f(-3)=3(9)-4(-3)+6
Multiply/Distribute
f(-3)=27+12+6
Add:
f(-3)=45
Hope this helps!
Answer:
f(x) = 45
Step-by-step explanation:
f (x) = 3x^2 − 4x + 6 find f (−3)
Replace the variable x with −3 in the expression.
f (−3) = 3(−3)^2 − 4 ⋅ −3 + 6
Simplify 3(−3)^2 − 4 ⋅ −3 + 6
Remove parentheses.
3(−3)^2 − 4 ⋅ −3 + 6
Raise −3 to the power of 2.
3 ⋅ 9 − 4 ⋅ −3 + 6
Multiply 3 by 9.
27 − 4 ⋅ −3 + 6
Multiply −4 by −3.

9 is 3% of what number? Which proportion matches this information?
Answers
Answer:
B
Step-by-step explanation:
3% = 3/100
So we can eliminate the first answer.
The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it.
As a result, we eliminate the third answer and remain with one reasonable answer
