4x-1<-13

Add 1 to both sides.

4x<-12

Divide by 4.

x<-3

Let's do both. For the first one, we can add 1 to both sides using the property of equality, and get 4x < -12. Then, we divide by 4, getting us x<-3. For the second, we subtract 3 from both sides to get -2x < 4. Then, we divide by -2 on both sides, but when we divide by a negative we have to switch the sign. So, we get x > -2. Hope this helps.

Answer:

The probability it will land on green every time is $\frac{1}{27}$ .

Step-by-step explanation:

We are given that a spinner is used for which it is equally probable that the pointer will land on any one of six regions. Three of the regions are colored red, two are colored green, and one is colored yellow.

The pointer is spun three times.

<u>As we know that the probability of an event is described as;</u>

Probability of an event = $\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}$

Here, the favorable outcome is that the spinner will land on green every time.

So, the number of green regions = 2

Total number of regions = 3(red) + 2(green) + 1(yellow) = 6 regions

<em>Now, the probability it will land on green every time is given by;</em>

Probability = $\frac{2}{6}\times \frac{2}{6}\times \frac{2}{6}$

= $\frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}$

= $\frac{1}{27}$

Hence, the probability it will land on green every time is $\frac{1}{27}$ .

Answer:

Step-by-step explanation:

*this is a 90 degree triangle

so we will use Pythagorean theorem to get X

hypotenuse²=side of right triangle²+the other side of right triangle²

50²=30²+x²

2500=900+X²

2500-900=x²

1600=x²

x=√1600

=40

so the answer is 40

Graph the line with a slope of -3/2 that passes through the point (-1,2)

olga nikolaevna [1]

Answer:

See diagram

Step-by-step explanation:

The line with the slope of $-\dfrac{3}{2}$ has the equation

$y=-\dfrac{3}{2}x+b$

This line passes through the point (-1,2), so

$2=-\dfrac{3}{2}\cdot (-1)+b\\ \\b=2-1.5\\ \\b=0.5$

The line has the equation

$y=-1.5x+0.5$

This line intersects the y-axis at point (0,0.5) and the y-axis at point (1/3, 0). Plot these points and connect them with the straight line (see attached diagram)
