PLEASE HURRY

Andrew solved the following inequality, and his work is shown below:

−4(x + 8) + 25 ≤ −2 + 1(x − 50)
−4x − 32 + 25 ≤ −2 + 1x − 50
−4x − 7 ≤ 1x − 52
−5x ≤ −45
x ≤ 9

What mistake did Andrew make in solving the inequality? (2 points)

Question 3 options:

1)

He subtracted 1x from both sides when he should have added 4x.

2)

When dividing by −5, he did not change the ≤ to ≥.

3)

He added 7 to both sides when he should have added 52.

4)

He did not make a mistake.

Answer:

Answer:

d-2x-3

Step-by-step explanation:

The factor of the trinomial will be (2x + 3) and (2x + 3). Then the correct option is D.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The trinomial is given below.

⇒ 4x² + 12x + 9

Then the factor of the trinomial will be

⇒ 4x² + 12x + 9

⇒ 4x² + 6x + 6x + 9

⇒ 2x(2x + 3) + 3(2x + 3)

⇒ (2x + 3)(2x + 3)

⇒ (2x + 3)²

Then the correct option is D.

Answer:

2.6667 hours

Step-by-step explanation:

Given that:

Distance between car and bus = 280 miles apart

What le moving towards each other ;

Speed of car = 55 mph

Speed of bus = 50 mph

Time it will take them to meet;

Time = distance / speed

Hence :

Total distance to be covered = 280 miles

Total speed = (55mph + 50 mph) = 105 mph

Hence ,

Time = 280 miles / 105 mph

Time = 2.667 hours

2 hours, (0.667 * 60 = 40.02

Answer:

-10p

Step-by-step explanation:

-4p+(-6p)            for me I like to think of the negative or subtraction sign                

                          overpowering the positive or addition sign

so in this case

-4p-6p

then since the variable p is the same -4-6 is -10

the end result is -10p

Answer:

These lines are linear lines.

Step-by-step explanation:

Linear lines are straight lines. We can determine if a line is linear in one of a few ways, three being:

By looking at the lines. If they are straight, then they are linear.

By looking at a graph. If there is a constant rate of change within the graph (between the points), then the line is linear. A constant rate of change is when something is changing at a constant, or not-changing number. For example, if the rate of change is 3 (+3 or -3), and never any other number, then the line is linear.

By solving the equation. For a line to be linear, it has to be able to fit in the slope-intercept form (y = mx + b) (without any exponents). If the equation does not work for the line, then the line is likely non-linear. A linear line may also have two expressions that are equal to each other. It's a little hard to see the entire second equation in the picture, but it appears to be 4x - 7. Meanwhile, the first equation is -2x + 5. Clearly, both lines are linear as they both fit in/follow the slope-intercept form. The m's are: -2 and 4, and the b's  are 5 and -7.

Step-by-step explanation:

To solve this, you first plug in the 4 and 2 where the x and y's go, making the expression (4 - 2(2))*(4 + 2(2)). Then you solve each parenthesis (below).

(4 - 2(2))*(4 + 2(2)).

(4 - 4)*(4 + 4).

Answer:

14 miles

Step-by-step explanation:

You divide. 132/13

Which gives you 14. Every 14 miles, the riders replaced a horse.

So, They rode 14 miles before replacing each horse.

Hope this helps:)

Answer:

14 miles

Step-by-step explanation:

182/13 = 14 miles

Assuming each horse was only ridden once

then a total of 16 horses were ridden for a total of 182 miles

182 miles /13  horses  = 14  miles  horse

Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.

Note that the fact that there were 3 riders is irrelevant.

Answer:

y = -5x + 4

Step-by-step explanation:

In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.

Answer:

y = -5x - 1

Step-by-step explanation:

Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.

Point slope formula = y - y = m(x - x)

m = -5    (-1, 4)

y - 4 = -5(x +1)

y - 4 = -5x - 5

y = -5x - 1

Answer: [tex]y=5.666667[/tex]   or   [tex]y=5 \frac{6}{9}[/tex] in fraction

Step-by-step explanation:

1. Simplify  -9.8-y+2.8y  to  -9.8+1.8y

0.4=-9.8+1.8y0.4=−9.8+1.8y

2. Regroup terms

0.4=1.8y-9.8

3. Add 9.8 to both sides.

0.4+9.8=1.8y

4. Simplify  0.4+9.8  to  10.2

10.2=1.8y

5. Divide both sides by 1.8

[tex]\frac{10.2}{1.8} =y\\[/tex]

6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667

5.666667 = [tex]y[/tex]

7. Switch sides.

[tex]y=5.666667[/tex]

Answer:

See below.

Step-by-step explanation:

We have the expression:

[tex]\sqrt{8c+4}[/tex]

And we want to determine the domain restrictions of the expression.

Remember that the radicand (expression under the square root) must always be positive or 0. This is because we can't take the square root of a negative (and the square root of 0 is just 0). So, to find the domain restrictions, we can write and solve for the following inequality:

[tex]8c+4\geq0[/tex]

This is saying (8c+4) must be greater than or equal to 0. In other words, it's positive or 0.

So, solve for c. Subtract 4 from both sides:

[tex]8c\geq-4[/tex]

Now, divide both sides by 8. This yields:

[tex]c\geq4/8\\c\geq -1/2[/tex]

So, our c must be greater than or equal to -1/2. If it is less than -1/2, we won't have a solution.
