Determine the equation of the line with slope 3 that passes through the point M(1.2).
?

Answers

Answer 1

Answer: y = 3x - 1

The format for slope intercept form is:

y = mx + b

m represents the slope and that was given so:

y = 3x + b

Now we have to substitute the value from the given point into “y” and “x” to solve for “b”

(2) = 3(1) + b
2 = 3 + b
-1 = b

Now that we know b we can substitute it into y = 3x + b to get the equation of the line

y = 3x - 1

Answer:

7) 40

8) 23

9) 63

Step-by-step explanation:

180 degrees in a triangle. Add the 2 degrees they give you, and then subtract that from 180 to find the missing angle.

82 + 58 = 140 180 - 140 = 40

115 + 42 = 157 180 - 157 = 23

27 + 90 = 117 180 - 117 = 63

Hope this helps.

Answer:

7=40, 8=23, and 9=63

Step-by-step explanation:

The key info to solve is that in a triangle there are 180 degrees

7) we add 82 and 58 and then subtract the total from 180 to find x

=82 + 58 = 140, and 180 - 140 = 40, so 40=x

We do the same for the rest

115 + 42 = 157, and 180 - 157 = 23, so 23=x

Wait whats that square in the triangle? It represents 90 degrees, a right angle!

so, 27 + 90(right angle) = 117, and 180 - 117 = 63, so 63=x

Donald bought a box of golf balls for $9.59. There were 18 golf balls in the box. About how much did each golf ball cost?

Answers

The price (9.59) divided by the number of golf balls (18).

9.59 (divided by) 18 = .53

One golf ball cost around $0.53 or 53 cents.

You can also check the work by multiplying 18 by 0.53 which is 9.59.

One pack costs $9.59, which contains 18 balls. To obtain the cost of each ball, you divide $9.59 by 18, which is about 53 cents

Factor the polynomial expression x6 – x3 – 20

Answers

Answer:

x6 − x3 − 20 = (x3)2 − x3 − 20 = (x3 + 4)(x3 − 5)

Step-by-step explanation:

In this trinomial, the exponent of the first term, 6, is double the exponent in the second term, 3. And, the third term contains no variables. So, we can factor the expression as we would a quadratic, but treating x3 as if it were x:

Answer:

(x³ - 5)(x³ + 4)

Step-by-step explanation:

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x³ term (- 1)

The factors are - 5 and + 4, since

- 5 × 4 = - 20 and - 5 + 4 = - 1, hence

$x^(6)$ - x³ - 20 = (x³ - 5)(x³ + 4)
