6x - 2 = X + 13 what does X equal?
if you can pls show how you got it
Answer:
The answer is 3!!
Step-by-step explanation:
Step 1)
6x-2=x+13
6x − 2 + 2 = x + 13 +2
Step2)
6 = + 15
Step3)
6 − =+15−
Step 4)
5=15
Step5)
5x=15
Divide both sides
5x/5 = 15/5
Step 6)
X = 3!!
if the gradient of a line is 2 and (7,2) is a point on the line, find it's equation
Answer:
y = 2x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c is the partial equation
To find c substitute (7, 2 ) into the partial equation
2 = 14 + c ⇒ c = 2 - 14 = - 12
y = 2x - 12 ← equation of line
How many numbers x between 1 and 100 (inclusive) have the property that x2+x3 is a perfect square?
(Please help. I'm suffering)
=========================================================
Explanation:
Factor the given expression
x^2+x^3
x^2*1+x^2*x
x^2(1+x)
x^2(x+1)
We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.
In short, we don't need to worry about the x^2 portion.
--------------------
The only thing of importance is the x+1 factor.
The x+1 must be a perfect square so that the original expression is as well.
Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}
If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".
Subtract 1 from each item to end up with this modified set
{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}
--------------------
Every item mentioned in that second set will make x^2+x^3 to be a perfect square.
For example, let's pick x = 15
x^2(x+1) = 15^2*(15+1)
x^2(x+1) = 15^2*16
x^2(x+1) = 15^2*4^2
x^2(x+1) = (15*4)^2
x^2(x+1) = 60^2
This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.
There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.
--------------------
To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.
help, again my brain is useless
Solve please....................................
Answer:
angle (3x-15)°=angle (2x+10)° (by vertically opposite angles)
3x-15=2x+10
3x-2x=10+15
x=25
by putting the value of x.
3x-15=3×25-15 = 60°
38°+ 60°+ <ebf= 180° (by sum of all sides is 180° )
98°+<ebf = 180°
<ebf = 180° - 98°
<ebf = 82°

9. Write the equation of the line that is parallel to the line 5x - 4y = 4 and passes through the
point (-8, 2).
Answer:
y = 5/4x + 12
Step-by-step explanation:
4y = 5x - 4
y = 5/4x - 1
2 = 5/4(-8) + b
2 = -10 + b
b = 12

1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
A.f(–9) = 14
g(1) = 30
B.f(–9) = –78
g(1) = –11
C.f(–9) = –66
g(1) = 29
D.f(–9) = 8
g(1) = –80.75
2.Find the value of f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x3 – 24x .
A. f(–9) = 25
g(–1) = 21
B.f(–9) = –5
g(–1) = 20
C.f(–9) = 29
g(–1) = 26
D.f(–9) = 3
g(–1) = –27
Answer:
1. f(–9) = -66 , g( 1 ) = 27 (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.
2. Option A: f(–9) = 25, g(–1) = 21
Step-by-step explanation:
1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
f(x) = 8x + 6
f(–9) = 8(-9) + 6 = -66
g(x) = 9x + 20x − 2
g( 1 ) = 9( 1 ) + 20( 1 ) − 2 = 27
None of the given choices were correct (unless there's a typo error for Option C — it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(–9) = -66 and g( 1 ) = 27
2. f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x³ – 24x
f(x) = –3x – 2
f(–9) = –3(–9) – 2 = 25
g(x) = 3x³ – 24x
g(–1) = 3(–1)³ – 24(–1) = 21
Therefore, the correct answer is Option A: f(–9) = 25, g(–1) = 21
A car is 150 inches long. A truck is 60% longer than the car.
How long is the truck?
Answer: Therefore, the truck is 240 inches long.
Step-by-step explanation:
truck = 150 + 60% of 150
= 150 + 60/100 * 150
= 150+90
= 240 inches

In Earth's southern hemisphere, the summer season is from December to March and winter is from June to September. The table shows the highest temperatures recorded at the South Pole for three different months.
Graph model:
South Pole Temperatures
Month Highest temperature (°F)
January 6
June –24
November –2
Each month's highest recorded temperature is plotted on the number line.
4. Which month had the coldest of the three temperatures? Explain.
#4
June is the most coldest.
How?
Mention the temperatures
January=+6°F
June=-24°F
November=-2°F
Lowest is the coldest .(June is the coldest month)
January = 6°F
June = -24°F
November = -2°F
By the above given observation we can say that June is the coldest as it has the lowest temperature in all.

bChoose the equation that represents the graph.
Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is (d) y = x +3
The points on the line are:
[tex](x_1,y_1) = (-3,0)[/tex]
[tex](x_2,y_2) = (0,3)[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x1, x2, y1 and y2
[tex]m = \frac{3-0}{0--3}[/tex]
Simplify
[tex]m = \frac{3}{3}[/tex]
Divide
[tex]m = 1[/tex]
The equation of the line is then calculated using the following formula:
[tex]y = m(x - x_1) + y_1[/tex]
Substitute values for m, x1 and y1
[tex]y = 1(x - -3) + 0[/tex]
Simplify
[tex]y = 1(x +3)[/tex]
Open bracket
[tex]y = x +3[/tex]
Hence, the equation of the graph is (d) y = x +3

Jackson deposits $4,200 in a savings account that pays 3.5% annual interest.What is the total value of the account after 10 years
Answer:
5924, 51
Step-by-step explanation:
X = 4200(1.035)^10
And put it in a calculator
The total value of the account after 10 years is $5,924.52.
Given that,
The deposited amount is $4,200.The rate of interest is 3.5%.And, the time period is 10 years.Based on the above information, the calculation is as follows:
[tex]= \$4,200 \times (1 + 3.5\%)^{10}[/tex]
= $5,924.52
Therefore we can conclude that the total value of the account after 10 years is $5,924.52.
