Answer:

The correct answer to this question is 2.55 not 0.255 but even though those are the right numbers the 2 and the decimal point is in the wrong place so you just had the right numbers but the wrong

Answer:

4.25 feet of ribbon cost around $ 8.29

Step-by-step explanation:

We are given the following information in the question:

Length of ribbon to be bought by Brenna = 4.25 feet

Cost of 1 foot of ribbon = $1.95

Total or actual cost of the ribbon =

\text{Total length of ribbon}\times \text{Cost per unit length of ribbon}

Cost of ribbon to be purchased by Brenna =

\text{Estimation of cost of ribbon:}

4.25\times 1.95 = 8.2875 \approx \$8.29

Thus, to find the actual cost Brenna should use the product of total length of ribbon to be bought and the unit cost of the ribbon.

Hence, 4.25 feet of ribbon cost around $ 8.29

Use the distributive property to simplify the expression: -4(4x + 3) + (7x - 2)
Elodia [21]
-4(4x+3) + (7x -2) = (-16x + -12) + (7x + 2) = -16 + -12 + 7x + 2 = -9x -10
The answer is -9x -10

Answer:

Axis is a vertical line at x = 2

Vertex is (2, -1)

y-intercept is (0, 3)

Solutions are x = 1 and x = 3

Step-by-step explanation:

To draw the graph of the quadratic equation you must find at least 5 points lie on the graph by choose values of x and find their values of y

Let us do that

Use x = -1, 0, 1, 2, 3, 4, 5

∵ y = x² - 4x + 3

∵ x = -1

∴ y = (-1)² - 4(-1) + 3 = 1 + 4 + 3 = 8

→ Plot point (-1, 8)

∵ x = 0

∴ y = (0)² - 4(0) + 3 = 0 + 0 + 3 = 3

→ Plot point (0, 3)

∵ x = 1

∴ y = (1)² - 4(1) + 3 = 1 - 4 + 3 = 0

→ Plot point (1, 0)

∵ x = 2

∴ y = (2)² - 4(2) + 3 = 4 - 8 + 3 = -1

→ Plot point (2, -1)

∵ x = 3

∴ y = (3)² - 4(3) + 3 = 9 - 12 + 3 = 0

→ Plot point (3, 0)

∵ x = 4

∴ y = (4)² - 4(4) + 3 = 16 - 16 + 3 = 3

→ Plot point (4, 3)

∵ x = 5

∴ y = (5)² - 4(5) + 3 = 25 - 20 + 3 = 8

→ Plot point (5, 8)

→ Join all the points to form the parabola

From the graph

∵ The axis of symmetry is the vertical line passes through the vertex point

∵ x-coordinate of the vertex point is 2

∴ Axis is a vertical line at x = 2

∵ The coordinates of the vertex point of the parabola are (2, -1)

∴ Vertex is (2, -1)

∵ The parabola intersects the y-axis at point (0, 3)

∴ y-intercept is (0, 3)

∵ x² - 4x + 3 = 0

∵ The solutions of the equation are the values of x at y = 0

→ That means the intersection points of the parabola and the x-axis

∵ The parabola intersects the x-axis at points (1, 0) and (3, 0)

∴ Solutions are x = 1 and x = 3

Answer:

C f=9

Step-by-step explanation:
