If the graph of the linear equation ax-8y=15 has an x-intercept at (3,0), then what is the value of a?

Answers

Answer 1
Answer:   a = 5

====================================

Work Shown:

Plug in (x,y) = (3,0)

ax - 8y = 15

a(3) - 8y = 15 .... replace x with 3

3a - 8(0) = 15 ... replace y with 0

3a - 0 = 15

3a = 15

a = 15/3

a = 5

The equation updates to 3x - 8y = 15.

X^2-x-12, please show your work so I can know how to do it. Thank you:))

Answers

you have to split the -x into 2 numbers that multiply to the same product as the two outside numbers so x^2+3x-4x-12
then split it and factor x(x+3)-4(x+3)
then you get (x-4)(x+3)

Given:

[tex]y=\dfrac{2}{3}x^2+3[/tex]

This equation is in the form [tex]y=ax^2+bx+c[/tex].

To find:

The values of a, b and c.

Solution:

We have,

[tex]y=\dfrac{2}{3}x^2+3[/tex]

It can be written as

[tex]y=\dfrac{2}{3}x^2+(0)b+3[/tex]

On comparing this equation with [tex]y=ax^2+bx+c[/tex], we get

[tex]a=\dfrac{2}{3},b=0,c=3[/tex]

Therefore, the correct option is b.

What is division?

Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.

For example, if 50 apples are to be shared by 5 people , the number of apples allocated bto a person is 50/5 = 10 apples

196/3.5

to solve the we can multiply the numerator and denominator by 10 to make all whole number

= 1960/35

we can now simplify

divide through by 5

392/7

divide through by 7

= 56

therefore the value of 196/3.5 is 56

Answer:

Step-by-step explanation:

Let the unknown angle be ∠ABC

∠ABC + 78° + 37° = 180° (angle sum property of a triangle)

∠ABC + 115° = 180°

∠ABC = 180° - 115°

∠ABC = 65°

The perimeter of a rectangle is 50ft. If the length is one more than twice the width,
what is the length, width and area?

Answers

Answer: See explanation

Step-by-step explanation:

Let the width of the rectangle be x

Since the length is one more than twice the width. Therefore, the length will be: = 2x + 1

Perimeter of a rectangle = 2(length + breadth)

50 = 2(2x + 1 + x)

50 = 2(3x + 1)

50 = 6x + 2

6x = 50 - 2

6x = 48

x = 48/6

x= 8

Width = 8ft

Length = 2x + 1 = 2(8) + 1 = 16 + 1 = 17ft

Area = Length × Width = 17 × 8 = 136ft^2
