Solve the math problem
Answer: Positive
Step-by-step explanation:
The slope of a line can be calculated via rise/run, or [tex]\frac{(y_{2} -y_1)}{(x_2-x_1)}[/tex]
Because this equation outputs a positive number, the slope is positive.
Hope it helps :) and let me know if you want me to elaborate/plug values into the slope formula and solve.

If the simple interest on $7,000 for 9 years is $5,040, then what is the interest rate?
Answer:
8%
Step-by-step explanation:
7000(x)(9) = 5040
7000(x) = 560
x = 560/7000
x = 0.08
0.08 to percentage = 8%
-Chetan K
Step-by-step explanation:
given,
SI = $5040
Principal = $7000
Time = 9 yrs
we know,
R = SI × 100 / T × P
now,
Rate = 5040 × 100 / 9 × 7000
→ 504000/63000
→ 504/63
→ 8
therefore, Interest rate is 8%.

EFGH is a rhombus. Given EG = 22 and FH = 20, what is the length of one side of the rhombus?
Please help :/
Applying the properties of a rhombus and the Pythagorean Theorem, the length of one side of the rhombus is: 14.9
Recall:
The diagonals of a rhombus bisect each other at right angles, thereby forming 4 right triangles.Half of a diagonal and half of the other diagonal make up a right triangle.Thus, given:
EG = 22 (diagonal)FH = 20 (diagonal).Find the length of one side using Pythagorean theorem as shown below:
[tex]HG = \sqrt{(\frac{1}{2}EG)^2 + (\frac{1}{2}FH)^2 } \\\\[/tex]
Substitute[tex]HG = \sqrt{(\frac{1}{2} \times 22)^2 + (\frac{1}{2} \times 20)^2 } \\\\HG = \sqrt{11^2 + 10^2} \\\\\mathbf{HG = 14.9}[/tex]
Therefore, applying the properties of a rhombus and the Pythagorean Theorem, the length of one side of the rhombus is: 14.9

In 2015 Organization raised $543. The following year they raised $89. How many money did they raised over the two period? Show how answer using the 'Make ten Strategy'
Answer:
632
Step-by-step explanation:
So you take one from the 3 to make it 2 and add it on to 89 to make 90. next take 10 from 542 and add it to the 90, you get 100. Then 532 + 100 = 632
Hope this helps
Answer:
Step-by-step explanation:
543 + 89
from the 3 and 9 split 9 to get a ten with the 3: 3 + 7 + 2 so 2 goes into the units category of the answer:
..2
Now as 9 > 3 we add 1 to the tens digit
- that is 8 becomes 9.
from the 4 and 9 split 9 to get a ten with the 4: 6 + 3 so 3 goes into the tens category:
.32.
Now as 9 > 4 we add 1 to the 5, so the answer is 632.

Answer:
x=2; y=1
Step-by-step explanation:
Since the triangle is equilateral, which means three sides have the same length.
So we have：4x-y=2x+3y=7
[tex]4x-y=2x+3y\\4x-y+y=2x+3y+y\\4x=2x+4y\\2x=4y\\x=2y\\[/tex]
Since 2x+3y=7 and plug in x=2y
we have

and since y=1
x=2

Which ordered pair is the solution to the system of equations?
Y=2x – 15
4x + 3y = -5
A (0,6)
B (7, – 11)
C (4, – 7)
D (5, — 5)
Step-by-step explanation:
y = 2x - 15
4x + 3y = -5
4x + 3(2x - 15) = -5
4x + 6x - 45 = -5
10x = 40
x = 40/10
x = 4
y = 2x - 15
y = 2(4) - 15
y = 8 - 15
y = -7
Solution = (4,-7)

4x - 3y = 0

(0,0)
(6, 8)
(-3,6)
(-3,-4)
Answer:
(3,4)(-6, -8)(0,0)(6, 8)(-3,-4)Step-by-step explanation:
If you solve the equation for y, you get ...
4x = 3y
y = 4/3x
Then the ordered pairs of interest are the ones where y = 4/3x. Another way to say this is y/x = 4/3. (Can't use this with x=0.)

Find the rate of change: y = 5x - 2
A. 5
B. -2
C. 1/5
D. 2
Answer:
D. 2
Step-by-step explanation:
y = 5x - 2
At x = 0; y = 5(0) - 2 = - 2
(0, -2) is one point. It is Y intercept.
At Y = 0 ; 5x - 2 = 0 ; x = 2/5
(2/5, 0), is another point on the line.
Since it is a fraction , use your imagination to get two integers as co-ordinates.
At y = 8 ; 5x -2 = 8; 5x = 8 + 2 = 10 ; x =
