Solve: 2x – 3 = 5(x + 6)
Answer:
-11 =x
Step-by-step explanation:
2x – 3 = 5(x + 6)
Distribute
2x -3 = 5x + 30
Subtract 2x from each side
2x -3 -2x = 5x -2x +30
-3 =3x +30
Subtract 30 from each side
-3-30 =3x+30-30
-33 = 3x
Divide by 3
-33/3 = 3x/3
-11 =x
Answer:
x=(-11)
Step-by-step explanation:
2x - 3=5(x+6)
2x - 3 = 5x + 30
+3 +3
2x = 5x + 33
-5x -5x
-3x = 33
(divide both sides by -3)
x=(-11)

They are equal.
Choose the possible descriptions of cross sections formed by the intersection of a plane and a cylinder.
Answer:
Ellipses (special case is called a circle), hyperbolas, parabolas.
Step-by-step explanation:
These are all conic sections.
A conic section is defined by the cross section of a plane and a double-napped cone. There are other special cases called degenerate conics, which are lines and points (occurs when the equation does not follow the usual pattern, however, these are not considered main conics). The main types of conics are: ellipses, hyperbolas, and parabolas.
The illustration below gives more insight into the question.
I hope this helps.
Multiply the following complex numbers:
(5+3i)(4+ 2i)
A. 14-22i
O B. 14+ 22i
O C. 26 - 22i
O D. 26 + 22i
Answer:
B, or 14 + 22i.
Step-by-step explanation:
When multiplying complex numbers, use the FOIL method.
Therefore:
(5 + 3i)(4 + 2i)
FOIL the equation:
5×4 + 5 × 2i + 3i × 4 + 3i × 2i
Simplify. Remember that i² = -1.
20 + 10i + 12i -6
Combine like terms:
14 + 22i
Therefore, the solution is B, or 14 + 22i.
f(x)=(x-3)^2+5 plot the vertex and the axis of symmetry of this function.
Answer:
The vertex is located at (3,5)
The axis of symmetry is x = 3
The plot is in the image attached
Step-by-step explanation:
First we need to find the vertex of the quadratic function. We can find the x-coordinate of the vertex using the formula:
x_v = -b / 2a
Where 'a' and 'b' are coefficients of the quadratic equation in the model:
ax^2 + bx + c = 0
Then we need to expand the terms of f(x):
f(x) = (x-3)^2 + 5
f(x) = x^2 - 6x + 9 + 5
f(x) = x^2 - 6x + 14
So we have a = 1 and b = -6
Then the x-coordinate of the vertex is:
x_v = 6 / 2 = 3
We can use this value in f(x) to find the y-coordinate of the vertex:
f(x_v) = 3^2 - 6*3 + 14 = 5
So the vertex is located at (3,5)
The axis of symmetry is the vertical line traced in the vertex, so it is x = 3
The plot is in the image attached. The circle at (3,5) is the vertex, and the blue line is the axis of symmetry.

What is the solution of the equation (x – 5)^2 + 3(x – 5) + 9 = 0? Use u substitution and the quadratic formula to solve.
A) x=-3+3i√3/2 B) x=7+3i√3/2 C) x=2 D) x=8
Answer:
[tex] x = \dfrac{7 \pm 3i\sqrt{3}}{2} [/tex]
Step-by-step explanation:
(x – 5)^2 + 3(x – 5) + 9 = 0
This is a quadratic equation in x - 5.
Let u = x - 5, then the quadratic equation becomes:
u^2 + 3u + 9 = 0
We can use the quadratic formula to solve for u.
[tex] u = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] u = \dfrac{-3 \pm \sqrt{3^2 - 4(1)(9)}}{2(1)} [/tex]
[tex] u = \dfrac{-3 \pm \sqrt{9 - 36}}{2} [/tex]
[tex] u = \dfrac{-3 \pm \sqrt{-27}}{2} [/tex]
[tex] u = \dfrac{-3 \pm 3i\sqrt{3}}{2} [/tex]
Since u = x - 5, now we substitute x - 5 for u and solve for x.
[tex] x - 5 = \dfrac{-3 \pm 3i\sqrt{3}}{2} [/tex]
[tex] x = \dfrac{-3 \pm 3i\sqrt{3}}{2} + 5 [/tex]
[tex] x = \dfrac{-3 \pm 3i\sqrt{3}}{2} + \dfrac{10}{2} [/tex]
[tex] x = \dfrac{7 \pm 3i\sqrt{3}}{2} [/tex]

Answer:
B. 10
C. All real numbers.
Step-by-step explanation:
6 (2x-4) = 8(x + 2)
Distribute the numbers outside of the factors:
12x - 24 = 8x + 16
Subtract both sides by '8x'
12x - 8x - 24 = 8x - 8x + 16
4x - 24 = 16
Add '24' to both sides:
4x = 40
Divide both sides by 4:
x = 10. Therefore, B. 10 is the correct answer.
3(4p - 2) = -6(1 - 2p)
Distribute the numbers similarly to the example before:
12p - 6 = -6 + 12p
Subtract '12p' from both sides:
12p - 12p -6 = -6 + 12p - 12p
0 -6 = -6
Add '6' to both sides:
0 - 6 + 6 = -6 + 6
0 = 0
Therefore, the solution consists of all real numbers.
Which point on the graph represents the y-intercept?
Write the equation for the linear function that goes through –3 on the y-axis and has a slope of 0.5.
y= ????
Answer: y = [tex]\frac{1}{2} x[/tex] - 3
Step-by-step explanation:
The equation for a line is in the form y = mx + b, where "m" is the slope and "b" is the y-intercept.Since the slope is 0.5 (which is [tex]\frac{1}{2}[/tex]), we can plug that value in for "m": y = [tex]\frac{1}{2} x[/tex] + bSince the line goes through -3 on the y-axis, that is the y-intercept. So, we can just plug in that value for "b": y = [tex]\frac{1}{2} x[/tex] - 3And there's your answer: y = [tex]\frac{1}{2} x[/tex]-3Which value of x makes this inequality true?
X + 9 < 4x
We want to get out x's together on the right side of the inequality.
So, subtract x from both sides to get 9 < 3x.
Now divide both sides by 3 and we get 3 < x.
I personally like to have my variables on the left so we can move the 3 to the left and the x to the right but if we do that, we have to switch the inequality sign.
So we can rewrite this as x > 3.

Ramesh is a cashier in a canara bank. He has notes of denomination of Rs 100,50,10 respectively. The ratio of number of these notes is2:3:5respectively. The total cash with ramesh is 400000.How many notes of each denomination does he have
Answer: Ramesh has 80,000 100Rs, 120,000 50Rs and 200,000 10Rs.
Step-by-step explanation:
From the question, the ratio of number of 100, 50 and 10Rs notes is 2:3:5respectively and the total cash with ramesh is 400000.
Total ratio = 2+3+5 = 10
100Rs = 2/10 × 400000
= 80,000
50Rs = 3/10 × 400000
= 120,000
10Rs = 5/10 × 400000
= 200,000
Ramesh has 80,000 100Rs, 120,000 50Rs and 200,000 10Rs.

Solve for x. 5x - 1 = 26 x = x = 5 x = -5
Answer:
x = 27/5
Step-by-step explanation:
5x - 1 = 26
Add 1 to each side
5x - 1 = 26
5x-1+1 = 26+1
5x = 27
Divide each side by 5
5x/5 = 27/5
x = 27/5

A ladder is leaning against a wall. The length of the ladder is 15 meters and
the base of the ladder is placed 9 meters away from the wall. How far up
the wall will this ladder reach?
A.) 6 m
B.) 10 m
C.) 12 m
D.) 18 m
Answer:
the ladder is “c2” 15 X 15 =225
9 feet out is still squared to 81.
So c2 (225) - b2 (81) is 144 (a2)
Sqrt of 144 is 12. The ladder will be 12′ up the wall.

Answer:
32 polo, 28 measles
Step-by-step explanation:
4p + 2m = 184 <-- doses
p + m = 60 <-- vaccines
solve:
4p + 2m = 184
-2p - 2m = -120 <-- multiplied both sides by -2
------------------------
2p = 64
p = 32
plug back in:
32 + m = 60
p = 32
m = 28
Ricky has found that for every belt buckle he sells, he makes 7 + bx 4 dollars in profit, where b is the number of belt
buckles sold. How much profit will Ricky make by selling 52 belt buckles?
Answer:
215$ in profit
Step-by-step explanation:
So first, plug 52 into the equation. That makes it 7+52*4. In PEMDAS, multiplication goes first. So multiply 52*4. That makes it 208. So now plug 208 into the equation. That is 7+208. Finally, you finish the equation. 7+208 is 215, so Ricky make 215$ in profit.

The ratio of boys to girls in a class is 4:5
A. What fraction of the class are boys?
B. What fraction of the class are girls?
Answer:
Boys = 4/9
Girls = 5/9
Step-by-step explanation:
You add the ratio parts to find what the fraction is over.
5 + 4 = 9
Then you just need to know which part is boys and which is girls.
Boys to Girls = 4:5
Therefore Boys = 4/9 and Girls = 5/9.
Fraction of the class are boys = 4/9
Fraction of the class are girls = 5/9
What is ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given:
ratio of boys to girls = 4:5
Now, total of the ratio is = 4+5 = 9
So, fraction of the class are boys = 4/9
and, fraction of the class are girls= 5/9
