Answer-10x+46

Step-by-step explanation: hope this helps

Answer: Answer-10x+46

The equation that has infinitely many solutions is A. 4x + 5(2x + 6) = 14x + 30

An equation with infinitely many solutions is represented as:

ax + b = ax + b

This means that both sides of the equation must be the same.

Next, we test the options:

4x + 5(2x + 6) = 14x + 30

Open the bracket

4x + 10x + 30 = 14x + 30

Evaluate the like terms

14x + 30 = 14x + 30

Both sides of the equation must be the same.

Hence, the equation that has infinitely many solutions is A. 4x + 5(2x + 6) = 14x + 30

Step-by-step explanation:

(3 × 14) × 3 = 126

7 × 18 = 126

Boubacar will have to increase each dimension by 4 ft so that its area is triple.

The area of a rectangle is given by -

A[R] = L x B

where -

L is Length of rectangle

B is Breadth or width of rectangle.

Given is a deck that measures 3 feet by 14 feet. Boubacar wants to increase each dimension by equal lengths so that its area is tripled.

Assume that he increases the dimensions by x ft.

Initial Area = [A] = 3 x 14 = 42 ft².

Final Area = [A'] = 3[A] = 3 x 42 = 126 ft²

Initial dimensions = (L x B) = 3 feet x 14 feet

Final dimensions = (L' x B') = (3 + x) × (14 + x)

Now -

(L' x B') = 126

(3 + x)(14 + x) = 126

3(14 + x) + x(14 + x) = 126

42 + 3x + 14x + x² = 126

x² + 17x - 84 = 0

Solving the equation, we get -

x = 4  [ non negative number ]

Therefore, Boubacar will have to increase each dimension by 4 ft so that its area is tripled.

Answer:

-18 + x = 11

x = 29

Step-by-step explanation:

To solve this, you can use the formula of a + b = c

[tex]-18 + x = 11\\-18 = 18\\11 + 18 = 29\\x = 29[/tex]

Answer:

29

Step-by-step explanation:

Your equation can be -18+x=11. Since we don't know the number, we can use x. We are trying to find out a number that when it's added to -18, the answer will be 11.

Now, we solve the equation:

-18+x=11

x=11+18

x=29. Answer

To check this answer:

we can use our equation and substitute 29 for x.

-18+x=11

-18+(29)=11

11=11.

They are equal. Therfore, the answer is correct.

Answer:

x<-4 or x≤4

Step-by-step explanation:

The solution of the inequality is x > -4 and x ≤ 4.

So, the graph B is correct.

Given is an inequality, x+7 > 3 and x-5 ≤ -1, we need to solve and identify the graph,

To solve the compound inequality, let's solve each inequality separately and then find the intersection of the solutions.

Inequality 1: x + 7 > 3

Subtract 7 from both sides:

x > 3 - 7

x > -4

Inequality 2: x - 5 ≤ -1

Add 5 to both sides:

x ≤ -1 + 5

x ≤ 4

Now, we need to find the intersection of the solutions for both inequalities.

Since the conjunction between the two inequalities is "and," we need to find the common solution.

The common solution is the values of x that satisfy both x > -4 and x ≤ 4. From the two inequalities, we can see that the common solution range is from -4 to 4, including -4 but not including 4.

Therefore, the solution to the compound inequality is: -4 < x ≤ 4

Step-by-step explanation:

By applying concepts from vectorial calculus, we conclude that the gradient of the one variable function y = 2 · x³ - 7 · x + 4 when x = -2 is equal to 17.

A gradient is a generalization of the tangent curve used for multivariate function, that is, a function with more than one variable. In this case we have a function with one variable, which means that the gradient is equal to the slope:

[tex]\nabla f = \frac{df}{dx}[/tex]     (1)

Now we proceed to calculate the gradient of the curve:

[tex]\nabla f = 6\cdot x^{2}-7[/tex]

[tex]\nabla f = 6\cdot (-2)^{2}-7[/tex]

[tex]\nabla f = 17[/tex]

Step-by-step explanation:

once the level of medicine reaches a value, where 30% are 23mL (so, whatever is lost, is immediately replaced again), that is then the long run value for the amount of the drug in the patient's body.

so,

30% = 23 mL

1% = 30%/30 = 23/30 = 0.766666666...

100% = 1%×100 = 0.766666666... × 100 = 76.666666...

so, once the level reaches 76.666666... mL in the body, it will remain constant, as the daily filtered out 30% are 23 mL, and the daily add-on is also 23 mL.

so, the answer is

76.667 mL

Answer:

CE = 3.2 cm

DH = 4.5 cm

Explanation:

Given:

MNPR ≅ CEDH

≅ - means approximately equal

Lengths of the shape:

MN = CE = 3.2 cm

NP = ED = 6.5 cm

PR = DH = 4.5 cm

RM = HC = 9 cm

In general, they're not similar.

In any triangle with side lengths a, b, and c, we have the aptly-named triangle inequality that says the largest side is no larger than the sum of the smaller sides. In other words, if a and b are both smaller than c, then

a + b ≥ c

Suppose x < 12. Then BC corresponds to either YZ or XY.

• If BC corresponds to YZ, then the triangles are similar if and only if

BC/YZ = AB/XY = AC/XZ

x/2 = 9/3 = 12/4 = 3   ⇒   x = 6

• If BC corresponds to XY, then triangle similarity means

BC/XY = AB/YZ = AC/XZ

x/3 = 9/2 = 12/4

but this fails because 9/2 ≠ 12/4 = 3.

Suppose x > 12. Then BC corresponds to XZ, and

x/4 = 12/3 = 9/2

but this also fails because 12/3 = 4 ≠ 9/2.

(We ignore the case of x = 12 because that would make ∆ABC isosceles, and ∆XYZ certainly is not.)

So ∆ABC and ∆XYZ are similar only if x = 6. Under this condition, similarity would follow from the SSS similarity theorem.

Answer:

y = 3x - 4

Step-by-step explanation:

The general structure of a line in slope-intercept form is:

y = mx + b

In this form, "m" is the slope and "b" is the y-intercept.

(Step 1)

Before you can determine this equation, you need to find the value of "m". Since you were given the value of two points, you can find this by using the point-slope form. The general structure of the point-slope equation is:

y₁ - y₂ = m(x₁ - x₂)

y₁ - y₂ = m(x₁ - x₂)                              <---- Point-slope equation

-1 - 8 = m(1 - 4)                                  <---- Insert "x" and "y" values from table

-9 = m(1-4)                                         <---- Simplify left side

-9 = -3m                                            <---- Simplify inside parentheses

3 = m                                                 <---- Divide both sides by -3

(Step 2)

Now that you know "m", you can plug it and the "x" and "y" values of one point into the slope-intercept equation to find the value of "b".

y = mx + b                                         <---- Slope-intercept equation

y = 3x + b                                          <---- Plug 3 into "m"

-1 = 3(1) + b                                        <---- Plug "x" and "y" values in

-1 = 3 + b                                           <---- Multiply 3 and 1

-4 = b                                                 <---- Subtract 3 from both sides

(Step 3)

Now that you know that m = 3 and b = -4, you can substitute these values into the slope-intercept form to find your final answer. You can check your answer by plugging the "x" values from the table into the equation to verify that you get the correct "y" values.

y = 3x - 4

The calculation p=∛8  can be used to find the value of p in the equation p³= 8

An expression is combination of variables, numbers and operators.

The given equation is  p³= 8

p to the power of three equal to eight

p is the variable in the given equation

We have to find the value of p from the equation

Take cube root on both the side
