Answer:
Slope is 2.15
y-intercept is 2
Step-by-step explanation:
We need to find slope and y-intercept of the graph given.
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Looking at the graph, we can find 2 points
Point 1 : (0,-2)
Point (2): (2,-2.3)
Now putting values and finding slope:
We have: [tex]x_1=0, y_1=-2, x_2=2, y_2=-2.3[/tex]
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{2.3-(-2)}{2-0}\\ Slope=\frac{2.3+2}{2}\\ Slope=\frac{4.3}{2}\\Slope=2.15[/tex]
So, we get slope = 2.15
Now, finding y-intercept
y-intercept can be found if we put x =0
Looking at the graph, when x =0, y = 2
So, y-intercept is 2

What is the y intercept of the following equation -5y-3x=10
It has to look something like this
Answers
Answer:
-2
Step-by-step explanation:
First, let's put this in slope-intercept form:
-5y-3x=10
5y = -3x - 10
y = (-3/5)x - 2
The y-intercept is -2.
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.
Answers
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
Simplify 1/2 (10x + 20)

Which value of x is a solution of the inequality 25x - 100 < 250?
Answers
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.

Any real number strictly larger than 9 and strictly less than 21.
Step-by-step explanation:
By triangle inequality, the sum of the lengths of any two sides are greater than the length of the third side.
We therefore could set up three inequalities.
x+6>15, x+15>6, 15+6>x
Solving these, we get x>9, x>-9, x<21 i.e. 9 < x < 21.

for 3 year, what is the interest
250
540
450
2950
Answers
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

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.
