Answer:
(1.25, -1.5)
Step-by-step explanation:
The system of equations:
y = -2x + 1
y = -3/2
So we know that the two lines meet at the point where y = -3/2 = -1.5
∴ -1.5 = - 2x + 1
2x = 1 + 1.5 = 2.5
x = 2.5 ÷ 2 = 1.25
So the solution to this system of equation (or where the two lines meet) is the point (1.25, -1.5)
is this the area of a this

Answer:
Step-by-step explanation:
so first what you want to do is split the shape in to
Draw a line down where the 2 is.
you should have a rectangle and a triangle
then you find the area of the rectangle
Rectangle:
5 x 2 = 10m^2
After than you try to find the triangles area
the bottom of the triangle is 9m but since to split it in 2 you will now have 7m
multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2
Add your two areas together and you will get 27.5m^2

Add or Subtract to simplify
Answer:
3. - 8n² -8n + 3
Step-by-step explanation:
(4n^4 - 8n +4) - (8n² + 4n^4 +1)
Firstly, open the brackets.
= 4n^4 - 8n +4 - 8n² - 4n^4 - 1
Now, group like terms.
= 4n^4 - 4n^4 - 8n² -8n - 1 + 4
4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4
= - 8n² -8n - 1 + 4
= - 8n² -8n + 3

What Two pairs of fractions are shown. Which symbol correctly compares 2/3 2/4 each pair of fractions?
Answer:
Greater than symbol.
2/3 > 2/4
Step-by-step explanation:
We have two fractions, 2/3 and 2/4
We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).
Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.
2/3 and 2/4
With 2/3 being greater than 2/4.
2/3 = 0.67
2/4 = 0.50
Succinctly, 2/3 > 2/4.
The values of w is inversely proportional to m .If w=8 then m=25; what is m when w=20? Show me the steps please
Answer:
m = 10
Step-by-step explanation:
The values of w is inversely proportional to m
Mathematically:
w ∝ 1/m
w = k × 1/m
w = k/m
Where k is the Constant of Proportionality
Step 1
Solve for k
If w=8 then m=25
w = k/m
8 = k/25
Cross Multiply
k = 25 × 8
k = 200
Step 2
what is m when w=20? Show me the steps please
We solve for m
w = k/m
k = 200
20 = 200/m
Cross Multiply
20m = 200
m = 200/20
m = 10

Answer:
4. AC = 36
5. m<UTW = 42
Step-by-step explanation:
4.
AB = BC
-x + 25 = 3(2x - 8)
-x + 25 = 6x - 24
-7x = -49
x = 7
AC = 2(-x + 25) = 2(-7 + 25) = 2(18) = 36
AC = 36
5.
2x + 3 = 5x - 24
-3x = -27
x = 9
m<UTW = 2m<UTV = 2(2x + 3) = 2[2(9) + 3] = 2(21) = 42
m<UTW = 42

Look at the picture. Are the triangles similar? If so, choose the answer that explains why.
Answer:
yes. by AAA, i think she mistyped an A not sure
Step-by-step explanation:
The remaining angle of the bigger triangle = 180 - 84.6 - 30.4 = 65 (angle sum of triangle)
The three angles are the same for both triangles
The triangles are similar to each other because the angle-angle theorem is satisfied.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangles are given.
Let the third angle of the triangle be x. Then we have
84.6° + 30.4° + x = 180
x = 65°
Then the triangles are similar to each other because the angle-angle theorem is satisfied.
Thus, the correct option is C.

he needs 7 more customers
Step-by-step explanation:
have a wonderful day! brainliest?
Answer:
B. (7)
Step-by-step explanation:
First, we figure out how many more items Joshua needs to sell so we do 20 - 6.
20 - 6 = 14.
Next, we do 14 / 2 because each customer buys 2 items.
14 / 2 = 7
Therefore, Joshua must have 7 additional customers to reach his goal.
