Answer:

(2, 0) represents the x-intercept for the linear equation.

Step-by-step explanation:

The given linear equation is 3y + 4x = 8

We have to find the ordered pair that represents the x-intercept.

Since x - intercept of any line means ordered pair will have y = 0.

So by putting y = 0 in the equation

3×0 + 4(x) = 8

4x = 8

x = 2

Therefore, ordered pair which represents the x-intercept will be (2, 0).

find the equation of a cubic function whose graph passes through points (3,0) and (1,4) and is tangent to x-axis at the origin

Tomtit [17]

Answer:

y = -2x^2(x - 3)

Step-by-step explanation:

Preliminary Remark

If a cubic is tangent to the x axis at 0,0

Then the equation must be related to y = a*x^2(x - h)

(3,0)

If the cubic goes through the point (3,0), then the equation will become

0 = a*3^2(3 - h)

0 = 9a (3 - h)

0 = 27a - 9ah

from which h = 3

From the second point, we get

4 = ax^2(x - 3)

4 = a(1)^2(1 - 3)

4 = a(-2)

a = 4 / - 2

a = -2

Answer

y = -2x^2(x - 3)

A bouncy ball is dropped such that the height of its first bounce is 2.75 feet and each successive bounce is 80% of the previous

Allushta [10]

Answer:

0.3 feet

Step-by-step explanation:

2.75(0.8)^x

in which x is the number of bounces after the firts bouce

bouce 12 would mean x=11

2.75(0.8)^11 = 0.2

Juanita bought one CD for $7.99 and one DVD for $8.99. The sales tax on these items was 7%. She also bought lunch for $4.25, inc

Thepotemich [5.8K]

87. Juanita started with 40 dollars in her pocket. Then she bought one CD for 7.99 dollars and 1 DVD for 8.99 dollars. It has a sales tax of 7% on these items. Plus she bought a lunch for 4.25 dollars including tax Solve: => 7.99 dollars + 8.99 dollars = 16.98 dollars => 16.98 dollars * .07 = 1.2 dollars => 16.98 + 1.2 = 18.18 dollars Plus the lunch => 18.18 + 4.25 = 22.43 dollars => 40 – 22.43 = 17.57 dollars

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 3

y = -3x + 6

Step 2: Solve for x

Substitute in y: 3 = -3x + 6
[Subtraction Property of Equality] Subtract 6 on both sides: -3 = -3x
[Division Property of Equality] Divide -3 on both sides: 1 = x
Rewrite/Rearrange: x = 1

Step 3: Solve for y

Define original equation: y = -3(1) + 6
Multiply: y = -3 + 6
Add: y = 3
