Answer:

y = -2.111...

x = 3.167

Step-by-step explanation:

Answer:

X= 3.16667

Step-by-step explanation:

other answer just in case

y-intercept = -19/9  = -2.11111

x-intercept = 19/6  =  3.16667

Answer:

Step-by-step explanation:

Answer:

w = x+2/a−3

Step-by-step explanation:

Let's solve for w

aw−x=3w+2

Step 1: Add -3w to both sides

aw−x+−3w=3w+2+−3w

aw−3w−x=2

Step 2: Add x to both sides

aw−3w−x+x=2+x

aw−3w=x+2

Step 3: Factor out variable w

w(a−3)=x+2

Step 4: Divide both sides by a-3

w(a−3)/a−3 = x+2/a−3

w = x+2/a−3

The value of w is (2+x)/ (a-3).

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

aw-x=3w+2

Now, solving for w

aw - 3w = 2 + x

w(a-3 )= 2+x

w= (2+x)/ (a-3).

Hence, the value of w is (2+x)/ (a-3).

Answer:

Total number of students = 50 students.

Step-by-step explanation:

Total number of books = number of books * frequency

1 * 3 = 3

2 * 5 = 10

3 * 12 = 36

4 * 25 = 100

5 * 4 = 20

6 * 1 = 6

Total number of books = 3 + 10 + 36 + 100 + 20 + 6

Total number of books = 175 books.

Now, to find the total number of students;

Total number of students = summation of frequency

Total number of students = 3 + 5 + 12 + 25 + 4 + 1

Total number of students = 50 students.

Answer:

The vertex of the graph is located at the point (3,6)

Step-by-step explanation:

Here, we want to know where the vertex of the equation if plotted will be

To get this, what we have to do is to equate the expression that we have in the absolute value to zero

After this, we then proceed to solve for the value of x

We have this as;

x -3 = 0

hence;

x = 0 + 3

x = 3

to get the y-value of the vertex, we look at the value at the side of the absolute value

This value is 6 and thus, the y-value of the vertex point is 6

So the coordinates of the vertex is (3,6)

Answer:

The possible range of the length of side LM is 8 < x < 26 ⇒ A

Step-by-step explanation:

In any triangle:

In the given figure

∵ LMN is a triangle

∵ LM = x, MN = 9, NL = 17

→ Find the sum of the lengths of MN and NL

∴ The sum of the lengths of MN and NL = 9 + 17 = 26

→ Find the difference between the lengths of MN and NL

∴ The difference between the lengths of MN and NL = 17 - 9 = 8

→ By using the rules above, x should be between 8 and 26

∴ 8 < x < 26

∴ The possible range of the length of side LM is 8 < x < 26

Answer: 190 minutes because if you divide 76 by 8 you get 9.5 which would be 9.5 minutes every mile so then since every mile is 9.5 minuets you multiply that by 20 and get 190 so it would be garret rode his bike 20 miles in 190 minutes

Answer:

V = a²b³ + acb² units³

Step-by-step explanation:

The volume of a rectangular prism is given by :

V = l×b×h

Here, l = b² units

b = aunits

h = ab+c units

So, the volume of the prism is given by :

V = b² × a × (ab+c)

= ab²(ab+c)

= a²b³ + acb²

Hence, the required volume is a²b³ + acb² units³.
