m2=(y+10)° and m4=(3y-24)° what is m<2 show all of your work.
Step-by-step explanation:
m∠2 = m∠4
y + 10 = 3y - 24
y - 3y = -24 - 10
-2y = -34
y = -34/-2
y = 17
m∠2 = y + 10
m∠2 = 17 + 10
m∠2 = 27°
Answer:
[tex]27 \degree[/tex]
Step-by-step explanation:
As the opposite angles are equal,
[tex]m < 2 = m < 4[/tex]
Given that,
m <2 = y + 10°
m <4 = 3y - 24
Therefore,
[tex]y + 10 = 3y - 24[/tex]
Now let's solve for y
[tex]y + 10 = 3y - 24 \\ 10 + 24 = 3y - y \\ 34 = 2y \\ \frac{34}{2} = \frac{2y}{2} \\ 17 = y[/tex]
Now let's find m<2
[tex]m < 2 = y + 10 \\ = 17 + 10 \\ = 27 \degree[/tex]
Hope this helps you.

pls help i will mark the brainlyest The difference between two whole numbers is 8. Twice the smaller number is 4 more than the larger number.
What is the smaller number?
Enter your answer in the box.
smaller number =
Answer:
Step-by-step explanation:
x - y = 8
2*y = x + 4 Reverse the equation
x + 4= 2y Subtract 4 from both sides
x = 2y - 4
Put that value for x in the first equation
2y - 4 - y = 8 Combine like terms on the ledt
y - 4 = 8 Add 4 to both sides
y = 8 + 4
y = 12
x - y = 8
x - 12 = 8 Add 12 to both sides
x = 8 + 12
x = 20

Turn 1: 6 trees cut
Turn 2: 8 trees planted
Turn 3: 1 tree cut
Answer the questions to find out whether Rebecca earned bonus points in the next 3 turns. Use the number line to help you add.

Step-by-step explanation:
21. Window Side Length A stained-glass window in a church is in the shape of a rhombus. The
perimeter of the rhombus is 7 times the length of a side in meters, decreased by 12. Find the
length of a side of the window.
Answer:
length = 4
Step-by-step explanation:
A rhombus has four equal sides so the perimeter equals 4 sides.
Let x = length of a side
Perimeter of the rhombus is 7 times the length of the side decreased by 12
4x = 7x - 12
-4x = -4x
0 = 3x - 12
+12 = +12
12 = 3x
12/3 = 3/3x
4 = x

FIND Y
PLEASE HELP ILL GIVE BRAINLIESTTTT :))
Answer:
y = 22
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the angles in the lower triangle and equate to 180°
∠ 1 + 19° + 41° = 180°
∠ 1 + 60° = 180° ( subtract 60° from both sides )
∠ 1 = 120°
∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so
∠ 2 = 120°
Sum the angles in the upper triangle and equate to 180
y + 120 + 38 = 180
y + 158 = 180 ( subtract 158 from both sides )
y = 22
What is a reasonable estimate for 786 x 217?
Answer:
160,000
Step-by-step explanation:
Estimations like this usually involve rounding to easy numbers to multiply. You could do this in a number of ways depending on your ability to keep track of factors in your head, but the easiest way (and what I assume your teacher is looking for) is to round to the nearest, largest-power-of-ten, which in this case is the hundreds. 786 is closest to 800, and 217 is closest to 200, and 200*800 is 160,000. No calculator required is the key. You can also be slightly more sure that this is reasonable because you rounded up for one and down for the other, approximately by the same amount, too.

Graph the following features:
Slope = -3/2
Y-intercept = -2
Answer:
The y-intercept is the point in which the line crosses the y-axis (meaning, you'd find -2 on the y-axis).
Slope is the movement up or down and left or right, from the y-intercept (in this case we'll move downwards 3 units and to the right 2 units, and we'll keep doing this until our line forms).
I'll graph it for you, so you can get a visual, (but you really should do what the other person said and check out Desmos. It's really neat, and you don't even have to download it.)
Hope this helps you :)
The graph of the line with a slope of -3/2 and a y-intercept of -2 is a downward-sloping line passing through the point (0, -2) and (2, -5).
To graph the given features, which include the slope and y-intercept, we can use the slope-intercept form of a linear equation, which is y = mx + b.
Given:
Slope (m) = -3/2
Y-intercept (b) = -2
Using these values, we can write the equation of the line as:
y = (-3/2)x - 2
To graph this line, follow these steps:
1. Plot the y-intercept: Start at the point (0, -2) since the y-intercept is -2.
2. Use the slope to determine the next point: Since the slope is -3/2, this means that for every 2 units you move to the right, you move down 3 units.
Start from the y-intercept point (0, -2) and move 2 units to the right, then 3 units down to plot the next point.
This gives us the point (2, -5).
3. Connect the two points: Draw a straight line passing through the plotted points (0, -2) and (2, -5).

Is the relationship shown by the data linear? If so, model the data with an equation.

y
–9
–2
–5
–7
–1
–12

–17
A. The relationship is not linear.
B. The relationship is linear; y + 9 = -4/5 (x + 2).
C. The relationship is linear; y + 2 = -5/4 (x + 9).
D. The relationship is linear; y + 2 = 4/5 (x + 9).
Answer:
C. The relationship is linear; y + 2 = (-5/4)x - 11.25
Step-by-step explanation:
If the relationship f is linear then its graph is a line D of equation y = ax+b
(-9 ,-2)∈D ⇔ -2 = -9a + b (1)
(-5 , -7)∈D ⇔ -7 = -5a + b (2)
(2)-(1)⇒ -5 = 4a ⇒ a = -5/4
-2 = -9a + b ⇒ -2 = -9(-5/4) + b ⇒ 2 +45/4 = -b ⇒ b = -13.25
then
D : y = (-5/4)x - 13.25 ⇒ y + 2 = (-5/4)x - 11.25
since (-1,-12) and (3,-17) are points of D (easy to check)
then it’s a linear relationship
