What is the x-intercept in this linear equation? 2y - 4x = -12

2 answers:

5 0

The x-intercept mean y=0 and it is always in the form (x,0)
so put y=0 in the equation. Then solve for x;
0-4x=-12
x=3
Thus x-intercept of this linear equation is (3,0).

English Translation

If I have the following exercise x = 8 + 9 * 4 + (32 * 2 + 5 * 4) + 3 * 6 applying the hierarchy of operations, the result would be?

a. 25

b. 45

c. 78

d. None of the above

Solution

The hierarchy of operations includes BODMAS.

B - Brackets

O - Order

D - Division

M - Multiplication

A - Addition

S - Subtraction

x = 8 + 9 * 4 + (32 * 2 + 5 * 4) + 3 * 6

Solving the bracket first.

The multiplication in the bracket are first simplified to give

x = 8 + 9 * 4 + (64 + 20) + 3 * 6

Then further simplifying the bracket

x = 8 + 9 * 4 + (84) + 3 * 6

We then solve the multiplication outside the brackets

x = 8 + 36 + 84 + 18

We now sum all of this

x = 146

In Spanish/En Español

La jerarquía de operaciones incluye BODMAS.

B - Soportes

O - Orden

D - División

M - Multiplicación

A - Suma

S - Resta

x = 8 + 9 * 4 + (32 * 2 + 5 * 4) + 3 * 6

Resolver el soporte primero.

La multiplicación en el paréntesis se simplifica primero para dar

x = 8 + 9 * 4 + (64 + 20) + 3 * 6

Luego simplificando aún más el soporte

x = 8 + 9 * 4 + (84) + 3 * 6

Luego resolvemos la multiplicación fuera de los corchetes

x = 8 + 36 + 84 + 18

Ahora sumamos todo esto

x = 146

Hope this Helps!!!

Answer:

Step-by-step explanation:

The two angles are formed from 2 intersecting lines. The angles are called vertically opposite angles. They are equal

4x + 21 = 85 Subtract 21

4x = 85 - 21 Combine

4x = 64 Divide by 4

x = 64/4

x = 16

A pendulum is swinging next to a wall. The distance from the bob of the swinging pendulum to the wall varies in a periodic way t

Alekssandra [29.7K]

Answer:

H(t) = 15 -6sin(2.5π(t -0.5))

Step-by-step explanation:

For midline M, amplitude A, period T and time t0 at which the function is decreasing from the midline, the function can be written as ...

H(t) = M -Asin(2π/T(t -t0))

Using the given values of M=15, A=6, T=0.8 and t0 = 0.5, the equation is ...

H(t) = 15 -6sin(2.5π(t -0.5))

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), i

elena-14-01-66 [18.8K]

We will solve the equation to find a zero of f(x): $-x^{2}-5x+50=0$
The formula is: $x_{12} = \frac{-b\pm \sqrt{b^{2}-4ac } }{2a}$ where:
a=-1, b=-5, c =50 $x_{12} = \frac{5\pm \sqrt{25+200} }{-2}= \frac{5\pm \sqrt{225} }{-2}= \frac{-10}{-2}=5$ This is the only solution because the other is: $\frac{5+10}{-2}= \frac{15}{-2}=-7.5$ which is not possible.
Answer: D) The diver hits the water 5 feet away horizontally from the board.
