(2x + 3)(x – 5) + 7 = ax² + bx + c What is the value of a, b, and c?

Answers

Answer 1

Answer:

a = 2 , b = - 7 , c = - 8

Step-by-step explanation:

expand and simplify the left side then compare the coefficients of like terms on both sides.

(2x + 3)(x - 5) + 7 ← expand factors using FOIL

= 2x² - 10x + 3x - 15 + 7 ← collect like terms

= 2x² - 7x - 8

compare to ax² + bx + c , then

a = 2, b = - 7 , c = - 8

Triangle XYZ is rotated to create the image triangle X'Y'Z'.

On a coordinate plane, 2 triangles are shown. The first triangle has points X (negative 2, 2), Y (1, 2), Z (0, 4). The second triangle has points X prime (2, negative 2), Y prime (negative 1, negative 1), Z prime (0, negative 4).
Which rules could describe the rotation? Select two options.

Answer:

R0, 180°

Step-by-step explanation:

Knowing that:

The coordinates of ΔXYZ is x '(-2, 2), Y(1, 2), Z(0, 4)

The coordinates of ΔX'Y'Z' is x'(2, -2), Y'(-1, -1), Z'(0, -4)

Coordinates of the preimage = (x, y)

Coordinates of the image = (-x, -y)

How many tablespoons of melted butter he used for 13 kilograms of

2
חח ך

Answers

Answer:

48.6 tablespoons

Step-by-step explanation:

If for every kg of flour 3.6 (3 3/5) tablespoons are used, then for 13.5 (13 1/2) kgs: 3.6 × 13.5 = 48.6 tablespoons are used.

From the question,

[tex]3\frac{3}{5}[/tex] tablespoons of melted butter = 1 kilogram of flour

The number of tablespoons of melted butter the baker can use for 13 kilograms of flour is calculated as

1 kilogram of flour =  [tex]3\frac{3}{5}[/tex] tablespoons of melted butter

[tex]13\frac{1}{2}[/tex] kilograms of flour = b

Cross multiply

1 kilogram of flour x b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter

b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter  /1 kilogram of flour

b = 48.6 tablespoons of melted butter

Therefore, the baker would use 48.6 tablespoons of melted butter for [tex]13\frac{1}{2}[/tex]kilograms of flour.

Answers

Step-by-step explanation:

John ran 3 miles this week.

Jane ran 10 times as far as John this week :

10×3 = 30 miles

but she ran this week 8 fewer miles than last week. in other words, last week she ran 8 miles more than this week :

30 + 8 = 38 miles.

so, last week she ran 38 miles.

The difference of two supplemtary angles is 58 degrees. Find the measures of the angles

Answers

Answer:

The measure of the angles are 61° and 119°

Step-by-step explanation:

Let the first angle = x°

let the second angle = y°

The sum of two supplementary angles = 180°

x° + y° = 180° ----- equation (1)

based on the given question; "the difference of two supplementary angles is 58 degrees."

x° - y° = 58° ------- equation (2)

from equation (2), x° = 58° + y°

Substitute the value of x into equation (1)

(58° + y°) + y° = 180°

58 + 2y = 180

2y = 180 -58

2y = 122

y = 122 / 2

y = 61°

The second angle is given by;

x° = 58° + y°

x = 58° + 61°

x = 119°

Thus, the measure of the angles are 61° and 119°

What is the Value of 3.1 + (-4) - (-0.7)i mostly want to just check my answer In the early part of this century, the drug company, Merck, produced a powerful non- steroidal anti-inflammatory drug (NSAID) known as Vioxx. Vioxx was very effective in reducing pain due to arthritis and, unlike some NSAIDs, did not cause digestive system or liver problems. However, a couple of years after Vioxx was introduced to the market, some independent studies showed a possible connection between NSAIDs and increased risk of heart attack in the elderly. Since many arthritis sufferers (and many Vioxx users) are elderly, these studies were a cause of concern.To test whether this was the case for Vioxx, Merck conducted a large-scale study in which 3025 randomly selected elderly Vioxx users were put on the drug while 2875 were given a placebo. The volunteers were monitored for 18 months. During this time, 334 of the Vioxx group members and 272 members of the placebo group suffered heart attacks.Required:a.
