What is the rate of change of a line that passes through the points (-3,5) and (2,-1)?
Answer:
3/4
Step-by-step explanation:
The slope of the line is
m = (y2-y1)/(x2-x1)
= (-2--5)/(6-2)
= (-2+5)/(6-2)
=3/4

6. If Birr 2500 invested at 6% simple interest per annum,
for 3 year, what is the interest
250
540
450
2950
Answer:
The interest is 450 ⇒ C
Step-by-step explanation:
The formula of the simple interest is I = Prt, where
I is the intersetP is the investment amountr is the rate in decimalt is the time in years∵ Birr invested 2500 at 6% simple interest per annum for 3 years
∴ P = 2500
∵ r = 6%
→ Divide it by 100 to change it to decimal
∵ 6% = 6 ÷ 100 = 0.06
∴ r = 0.06
∴ t = 3
→ Substitute them in the formula above
∵ I = 2500 × 0.06 × 3
∴ I = 450
∴ The interest is 450

Answer: 1. 12 2. 120
Step-by-step explanation:
1. so basically 9/6=18/x
since they are similir the'd have the same ratio
sooo you just solve for x (multiply 6 by 18, and then divide by 9) and you get 12
2. same thing except you put 6/10=12/x, and solve it (multiply 10 by 12 and divide by 6) and u get 20
dats how i would do it but there are other ways too im sure :)
hope this helps
4. Is the point (5,-26) a solution to the following
system of equations? Show your work.
y = -5x - 1
y=-3x - 2
Answer:
No,
Step-by-step explanation:
y = -5x - 1
y=-3x - 2
y=-5x-1
-26=-5(5)-1
True
now
y=-3x-2
-26=-3(5)-2
−26≠−17
False
It is not a solution to both of them
Some number was divided into 42. This quotient was then multiplied by 8,after which the resulting product was added to 10. Given this sum totalled to 34,find the initial number.
Answer:
126
Step-by-step explanation:
In order to find the initial number, we need to create the expression that is being mentioned and solve for the initial value by applying the opposite expressions to isolate the variable.
(((x / 42) * 8) + 10) = 34 ... subtract 10 from both sides
((x / 42) * 8) = 24 ... divide both sides by 8
(x / 42) = 3 ... multiply both sides by 42
x = 126
Finally, we can see that the initial value was 126

Find the missing dimension. Use the scale factor 1 : 12.
Answer:
15in
Step-by-step explanation:
Convert the 15 ft to inches (180) and then set up the proportion.\frac{1}{12} = \frac{x}{180}121=180x . Cross multiply to get that 12x = 180 and x = 15 inches.
Which value of x is a solution of the inequality 25x - 100 < 250?
Answer:
inequality form: x<14
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
The solution of the given inequality is set of all x such that x < 14.
What are Inequalities?Two or more expressions connected with symbols of inequality like ≥, ≤, > and < is called the inequalities.
There are different kinds of inequalities like polynomial inequalities which includes linear inequalities and quadratic inequalities, rational inequality and so on.
Linear inequalities will have the highest degree of the variable equals 1.
Given a linear inequality,
25x - 100 < 250
Adding both sides of the inequality with 100,
25x - 100 + 100 < 250 + 100
25x < 350
Dividing both sides of the inequality by 25,
25x / 25 < 350 / 25
x < 14
Hence the value of x in the inequality is all the values of x which are less than, < 14.

Option B is correct that is false.
We have been given a figure we need to tell that the two lines are perpendicular.
Lines are perpendicular if they meet at the right angle.
Line CD is perpendicular AB to vice-versa is not true.
Hence, Option B is correct
What is perpendicular with examples?Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .
The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other.
Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.
