Answer:

2,-12

Step-by-step explanation:

The given equation is ,

$\implies |x + 5 | = -7$

We know that modulus only gives positive value , Therefore on squaring both sides we have ,

$\implies (x + 5 )^2=( -7)^2 \\\\\implies (x+5)^2=7^2\\\\\implies x + 5 =\pm 7 \\\\\implies x = 7-5,-7-5 \\\\\implies \boxed{ x = 2, -12}$

Write an equation of the line with the given slope that contains the given point.

Alchen [17]

Answer:

$y=-2x+12$

Step-by-step explanation:

We can use the point-slope form given by:

$y-y_1=m(x-x_1)$

Where <em>m</em> is the slope and (x₁, y₁) is a point.

So, we will substitute -2 for <em>m</em> and (5, 2) for (x₁, y₁). This gives us:

$y-(2)=-2(x-(5))$

Simplify:

$y-2=-2(x-5)$

Distribute:

$y-2=-2x+10$

Add 2 to both sides. Hence, our equation is:

$y=-2x+12$

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tail

WINSTONCH [101]

Answer: Two-tailed test.

Population mean is the parameter which is tested.

Step-by-step explanation:

Given : $H_0: \mu=105$

$H_1:\mu\neq105$

We know that , the alternative hypothesis ( $H_1$ ) indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.

Here, the alternative hypothesis ( $H_1$ ) is two-tailed, so the hypothesis test is a two-tailed test.

Also, the parameter present in the hypothesis is $\mu$ which is a symbol to represent the population mean.

Thus , Population mean is the parameter which is tested.

Right triangle means:
sin, cos, and tangent

Here, we can see that:
sin 35° = $\frac{x}{20}$

Simplify.

20sin 35° = x

Multiply 20 by sin of 35 degrees.

x = 11.47(ROUNDED)

Based on a kc value of 0.210 and the data table given, what are the equilibrium concentrations of xy, x, and y, respectively?
