Find any two points on the line.

x=0⇒y=4(0)+7=7⇒ Point 1: (0,7)

x=−1⇒y=4(−1)+7=3⇒ Point 2: (−1,3)

Step 2: Plot the two points from Step 1

Step 3: Draw a straight line through both points

Answer:

It is located 7 units up.

Step-by-step explanation:

As you can see both graphs are linear since they don´t have quadratic or exponential terms, so both graphs are linear and can be determined, now the point where the graphs intersect with the Y axis will be different, because when the value of X is 0, in the first one the Y equals 7 and in the other the Y equals 0, so the lines are paralallel but are 7 units apart from eachother in the Y axis.

A rectangle flower bed is 9 feet wide and 12 feet long .what is the length of the diagonal?

BigorU [14]

Answer:

15 feet

Step-by-step explanation:

The question talks about;

A rectangular flower bed whose dimensions are 12 ft by 9 ft

We are required to determine the length of the diagonal

To answer the question, we need to know the following;

All the angles in a rectangle are right angles
A diagonal divides a rectangle into two right-angled triangles
The dimensions of the rectangle acts as the legs of right angled triangle.

Therefore;

Using Pythagoras theorem;

a² + b² = c²

Where, c is the hypotenuse (in this case the diagonal)

a and b are the shorter sides of the right-angled triangle

Therefore;

c² = 12² + 9²

c² = 144 + 81

= 225

c = √225

= 15

Therefore, the length of the diagonal is 15 feet

If alpha beta are the roots of the equation

Vikki [24]

Answer:

Step-by-step explanation:

Hello, I believe that we can consider a different from 0.

By definition of the roots we can write.

$ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\ \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }$
