I need help with #6 please help if you can
Answer:
Please find attached
Step-by-step explanation:
Answer:
65
Step-by-step explanation:
2x + 25 + 25 = 180
2x + 50 = 180
2x = 180 - 50
2x = 130
2x / 2 = 130 / 2
x = 65
help me solve for t please
Answer:
t = 1/3
Step-by-step explanation:
for this problem we have two different shapes, what we need to do is find out the proportional relationship between the two to solve for t, lets take one of the measurements from the smaller shape, we will go with... JK at 5
now all we need to do is divide that by the larger shapes same side, in this case that would be RP at 22.5, heres what that looks like so far
5 / 22.5 = 0.2-> (the two goes on forever, normally this is represented by a line above the infinite number, this is what they call a Repeating Decimal)
ok, so now that we have the rate of change between the two shapes figured out, now we just make the same change to the last side from the same side on the first shape, wich is LK to QR as shown
1.5 * 0.2-> = 0.3->
and if 0.3 is = to 1/3, so t = 1/3
i hope this helped you out, im sorry if im a little late lol, make note that all of this can be applied to similar situations, just figure out the change(s) that happened from one shape to the other, and make that same change on the unknown side or area
take care :D
Can you help me with these two? Sorry!

The points (2, 3) and (3, 6) fall on a particular line. What is its equation in slope-intercept
form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y=3x-3
Step-by-step explanation:
insert the first point into y=mx+b
3=2m+b
----------------
Do it again with the other point
6=3m+b
-------------
Now put both equations in a system of equations
3=2m+b
6=3m+b
solve for m and b
m=3 and b=-3
y=3x-3
m=slope
b=y-intercept

Answer:
1. [tex]y=\frac{2}{3}x-2[/tex]
2. [tex]y=\frac{-5}{4}x+5[/tex]
Step-by-step explanation:
all you are doing is solving for "y"
Answer:
ans 1. -2x = -6-3y
-2x = 9y
xy = -2/9
ans 2. 5x = 20 - 4y
5x = 16y
xy = 5/16

I need to know X for 8 and 10 if u feel like it. PLS
Answer:
8) x=9
10) 23 degrees
Step-by-step explanation:
8) vertical angles are congruent to each other so we can set the expressions as such and solve:
7x + 3 = 10x - 24
3 = 3x - 24
27 = 3x
9 = x
10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:
12x + 7 + 6x - 7 = 90
18x + 7 - 7 = 90
18x = 90
x = 5
now we plug it back into the expression equivalent to the measure of angle O:
6(5) -7
30 - 7
23 degrees

In circle O, chords AC and BD intersect at E. If MCD= 120 and MAB=100, what is BEC?
Answer:
D. 70°Step-by-step explanation:
∠BEC is supplementary with ∠BEA
Find the measure of ∠BEA
m∠BEA = 1/2(mCD + mAB)m∠BEA = 1/2(120° + 100°) = 110°Supplementary angles sum to 180°
m∠BEC + m∠BEA = 180°m∠BEC = 180° - 110° = 70°Correct choice is D

2. y=1/2x +4
3. f(x)=-2/3 +4
Answer:
#3
Step-by-step explanation:
The line follows an inverted slope format, indicated by -2/3. Or down 2, and 3 to the right after going up by 4, creating the line. The other equations would flip the line horizontally because of a positive slope.
