5(3x - 2) – 4(2x
+ 1) x=

Answer:

Step-by-step explanation:

Well you have one of the roots -- -10. Just by looking at it, -1 would seem to be another x intercept.

f(x) = (-1)^3 + 13(-1)^2 + 32(-1) + 20

f(x) = -1 + 13 - 32 + 20

f(x) = 0

So - 1 is also a root.

You should try -2

-2 * -10 - 1 = - 20

f(-2) = (-2)^3 + 13(-2)^2 + 32(-2) + 20

f(-2) =  -8 + 13 * 4 - 32(2) + 20

f(-2) = - 8 + 52 - 64 + 20

f(-2) = -72 + 72

f(-2) = 0

The zeros are

x = -10

x = -1

x = -2

Answer:

Step-by-step explanation:

You have a bunch of numbers that are likely confusing you.

When the bags are full, they weigh 3/4 of a pound.

If they are half full, then they weigh 3/4 * 1/2 = 3/8 of a pound.

Since there are three of them, then the total weight is 3(3/8) = 9/8 = 1 1/8

Answer:

1.31

Step-by-step explanation:

52.40÷40=1.31

I hope this helps:)

Jasmine's cost per liter of petrol is £1.31 when she pays £52.40 for 40 liters.

Total-Cost is divided by the quantity of units (liters) to find out how much each unit costs.

We know that : Cost of petrol is = £52.40,

The Quantity of petrol is = 40 liters,

The Cost per-liter can be calculated as = Total cost / Quantity of petrol

Substituting the values,

We get,

Cost per liter = £52.40/40,

Cost per liter = £1.31,

The concept of dividing the total cost by the quantity gives you a standard way to measure and compare costs on per-unit basis.

Therefore, the required cost per liter of petrol for Jasmine is £1.31.

All I know is that it is acute and less than 51 degrees

Answer:

AOB is 39 degrees.

Step-by-step explanation:

Given that ∠DOE is 51 degrees we know that ∠AOE is 180 degrees as it is a straight line.

∠BOD is a right angle given the ∟symbol so therefore ∠BOD is equal to 90 degrees.

m∠DOE + m∠BOD = 141 degrees (because 51 + 90)

Therefore m∠AOB = 39 because 180 - 141 = 39

Straight angles are equal to 180! Hope this helped

Answer:

Step-by-step explanation:

y = 63    {Vertical angles are congruent}

y + z + 85 = 180   {Angle sum property of triangle}

36 + z + 85 = 180

      z + 121 = 180

               z = 180 - 121

z = 59

63 +  x = 130   {External angle  property of triangle}

       x   = 130 - 63

x = 67

Answer:

1/20 is the correct answer

Step-by-step explanation:

65/100 diet

30/100 caffeine

Of the 65/100, 22 are caffeine free but that is unnecessary info for the question. The 22 caffeine free would fall under the 65/100 anyways.

So 65 + 30 = 95

100-95 = 5

5/100 simplified is 1/20

Yes, you are correct . Since we know 65 sodas are diet and 30 are caffeine-free.

65 + 30 = 95

What plus 95 equals 100?

95 + x = 100

Or 100 - 95 = 5

= 5/100

When 5/100 is simplified, it equals 1/20.

Answer: She would make $96.00

The equation best represents a line parallel to the given line is y = 9/5x - 2/15.

The general equation of a straight line is

y = mx + c,

where m is the gradient, and y = c is the value where the line cuts the y-axis.

This number c is called the intercept on the y-axis.

Now it is given that the line passes through (-2,-4) and (3,5).

So here,

x1 = -2;

y1 = -4;

x2 = 3;

y2 = 5

Hence slope of the line is given as,

m1 = (y2 - y1)/(x2 - x1)

⇒ m1 = {5-(-4)}/{3-(-2)}

⇒ m1 = (5+4)/(3+2)

⇒ m1 = 9/5

Since both the lines are parallel, hence

m1 = m2 = 9/5

Therefore equation of line parallel to the given line will be,

(y - y1) = m2( x - x1)

⇒ {y-(-4)} = 9/5{x - (-2)}

⇒ y + 4  = 9/5(x +2)

⇒ y + 4  = 9/5x + 18/5

⇒ y = 9/5x + 18/5 - 4

⇒ y = 9/5x - 2/15

Hence, The equation best represents a line parallel to the given line is y = 9/5x - 2/15.

It mean more than -42 or equal to -42

please give me a brainliest answer

The inequality that represents the statement "A number x is no less than -42" is x ≥ -42.

The inequality that represents the statement "A number x is no less than -42" can be expressed as:

x ≥ -42

In this inequality, the symbol "≥" stands for "greater than or equal to." It indicates that "x" can take any value that is equal to -42 or any value greater than -42. If "x" equals -42, the condition is satisfied, and if "x" is greater than -42, the condition is also satisfied.

For instance, if "x" is -40, the inequality holds true, as -40 is greater than -42. Similarly, if "x" is 0 or any positive number, the inequality remains true, as all these values are greater than -42.
