Mathematics
1 answer:
VashaNatasha [74]2 years ago
4 0

Step-by-step explanation:

We make "x" the subject of formula

2x = 11 + 5

(-5 changes to +5 because it's crossing over the equal to sign =)

2x = 16

(divide both sides by the coefficient of x)

2x ÷ 2 = 16 ÷ 2

X = 8

2. x /4 + 2 = 3

(we solve the Left Hand Side first by finding the LCM)

x/4 + 2

x + 8 = 3

‐---‐------

4

(cross multiply)

x + 8 = 4(3)

x + 8 = 12

x = 12 - 8

x = 4

3. 2(x - 7) = 3x + 10

(2 multiplies the entire bracket)

2x - 14 = 3x + 10

(collect like terms)

2x - 3x = 14 + 10

-x = 24

(multiply both sides by the negative sign "-")

x = -24

The measure of the central angle AOB is by 30° greater than the measure of the inscribed angle which intercepts arc AB. What are
liberstina [14]

Answer:

  • inscribed angle: 30°
  • central angle: 60°

Step-by-step explanation:

The central angle is double the inscribed angle for the same intercepted arc. Since doubling the angle adds 30° to it, the original inscribed angle must be 30°.

Then the central angle is 30°+30° = 2·30° = 60°.

Given that (0, 3) is on the graph of f (x) find the corresponding point for the function f (x) - 2
zheka24 [161]

Answer:

(0,1)

Step-by-step explanation:

Let (0,3) lies on f(x), then:

f(0) = 3

Let

g(x) = f(x) - 2

To find the corresponding point that lie on g(x), we substitute x=0

This implies that:

g(0) = f(0) - 2

But f(0)=3

We substitute to get:

g(0) = 3 - 2 = 1

The required point is (0,1)
