for all values of x , a function f is defined by f(x)=x^2+7x+12 if f(a)=2, what could be the value of a?​

Answers

Answer 1
Answer:

Answer:

a = -2 or a = -5

Step-by-step explanation:

We want f(a) = a^2 + 7a + 12 = 2. We can subtract 2 from both sides of this equation to get a^2+7a+10=0. We can factor this to get that (a+2)(a+5)=0. When the product of two numbers is equal to zero, one of the numbers must be equal to zero. This means that either a + 2 = 0, in which case a = -2, or a + 5 = 0, in which case a = -5.

Answer:

m=1/2

Step-by-step explanation:

y1= 1

y2=6

x1= -10

x2-0

m= slope

m= y2-y1/x2-x1

m=6-1/0 - - 10

m= 6-1/0+10

m=5/10

m=1/2

Luis is doing his math homework. He has 30 problems in all. After an hour, he only has 1/6 of those problems left. How many problems does he have left?

Answers

Answer:

\huge\boxed{5}

Step-by-step explanation:

Luis has 30 problems and after one hour, (1)/(6) of those problems are left. This means that the total number of problems left will be 30 \cdot (1)/(6).

Multiplying by a fraction is the same as dividing by a whole. The denominator of (1)/(6) is 6, so we can divide 30 by 6.

30 / 6 = 5

Hope this helped!

Answer: 25

Step-by-step explanation: 1/6 of 30 is 5, so 30 minus 5 equals 25.

Please Help Me For the figure below m<ABC = 70°. Which theorem or postulate can be used to determine m<DBC? What is m<DBC? (pic of the drawing below)​

Answers

Answer:

38°

Step-by-step explanation:

<ABD and <DBC are two interior angles that make up <ABC.

Based on the Angle Addition Theorem, the following equation can be used to find m<DBC:

(3x + 5) + (6x - 16) = 70

Find x

3x + 5 + 6x - 16 = 70

9x - 11 = 70

9x = 70 + 11

9x = 81

x = (81)/(9)

x = 9

We are given that, m<DBC = (6x - 16)°

Plug in the value of x to find the measure

m<DBC = 6(9) - 16 = 54 - 16 = 38°

Adult tickets for the movies are $11.50 each and child tickets are $8.75 each. How much would a family with 3 adults and 5 children pay for their tickets? (Multi-Step)

Answers

Answer:

$78.25

Step-by-step explanation:

Each adult = $11.50

Each child = $8.75

3 adults and 5 children

(11.50 x 3) + (8.75 x 5)

34.5 + 43.75 = $78.25

11.50 x 3 = 34.50

8.75 x 5 = 43.75

34.50 + 43.75 = 78.23

$78.23
