What value of x makes this equation true? 12x - 15 =6 - 3x A. 7/3 B. 3/7 C. 5/7 D. 7/5
Answer:
7/5
Step-by-step explanation:
12x - 15 =6 - 3x
Add 3x to each side
12x+3x - 15 =6 - 3x+3x
15x -15 = 6
Add 15 to each side
15x -15+15 = 6+15
Divide by 15
15x/15 =21/15
x = 7/5
Answer:
[tex]\boxed{x = \dfrac{7}{5}}[/tex]
Step-by-step explanation:
Given equation:
[tex]12x - 15 = 6 - 3x[/tex]
To solve for x, we need to isolate the "x" variable on one side of the equation. The constant obtained on the other side of the equation will be the solution (x).
Add 15 both sides of the equation:
[tex]\implies 12x - 15 + 15 = 6 - 3x + 15[/tex]
[tex]\implies 12x = 21 - 3x[/tex]
Add 3x both sides of the equation:
[tex]\implies 12x + 3x= 21 - 3x + 3x[/tex]
[tex]\implies 15x= 21[/tex]
Divide both sides by 15 to isolate the cooeficient from "x".
[tex]\implies \dfrac{ 15x}{15} = \dfrac{21}{15}[/tex]
[tex]\implies x = \dfrac{21}{15}[/tex]
Simplify the value of "x" as required:
[tex]\implies x = \dfrac{7 \times 3}{5 \times 3}[/tex]
[tex]\implies \boxed{x = \dfrac{7}{5}}[/tex]

Two of the angles of a triangle measure 27º and 63º. Is the triangle a right triangle? Yes No Not enough information I don't know.
Answer:
Yes
Step-by-step explanation:
A right triangle has to have one 90 degree angle and all triangle angles must add up to 180 degrees.
27+63= 90
180-90= 90
So to answer your question, the triangle is a right triangle.

so to split 180 in a 1 : 3 : 2 ratio, we'll simply divide 180 by (1 + 3 + 2) and distribute accordingly

A safety auditor at a paint factory took a random sample of 25 cans of paint from a production run of over
1,000 cans and measured the amount of lead in each can of paint in the sample. The sample data were roughly
symmetric with a mean of 37 parts per million (ppm) of lead per can and a standard deviation of 18 ppm.
SPA
CRI
As
Based on this sample, which of the following is a 95% confidence interval for the mean amount of lead per can
of paint (in ppm) in this production run?
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 25 - 1 = 24 df, is t = 2.0639.
The other parameters are given by:
[tex]\overline{x} = 37, s = 18, n = 25[/tex].
Hence, the bounds of the interval are given as follows:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 37 - 2.0639\frac{18}{5} = 29.6[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 37 + 2.0639\frac{18}{5} = 44.4[/tex]
The 95% confidence interval is (29.6, 44.4).

We should go 4 units up from the zero in the coordinate plane.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
Given that, in the ordered pair (3, 4), the value of y is 4.
Here, in the ordered pair (3, 4), 3 is x-coordinate and 4 is y-coordinate.
The perpendicular distance from the x-coordinate 3 and y-axis is 3 units, which is 3 units right to the y-axis.
The perpendicular distance from the y-coordinate 4 and x-axis is 4 units, which is 4 units up to the x-axis.
Hence, we should go 4 units up from the zero in the coordinate plane.

What’s the function??? Pls help will give brainlest
all you have to do is plug in the number....
1st sc: y=-30
2nd: x=-1
3rd: x=5
4th: y = 29
Answer:
1. y = -30
2. x = -1
3. x = 5
4. y = 29
Step-by-step explanation:
1. y = -10x
f(x) = 3
y = -10*3
y = -30
2. y = -2x + 1
f(y) = 3
3 = -2x + 1
-2x = 3 - 1
-2x = 2
x = 2\-2
x = -1
3. y = 6x
f(y) = 30
30 = 6x
x = 30\6
x = 5
4. y = 5x + 9
f(x) = 4
y = 5*4 + 9
y = 20 + 9
y = 29

Write the equation of a line with a slope of 5 and a y-intercept of (0, 3). Write the equation in slope-intercept form.
Answer:
y=5x+3
Step-by-step explanation:
Hi there!
We are given that a line has a slope of 5, and a y intercept of (0,3)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
Since we were given the slope and the y intercept, we can simply substitute these values into the formula to find the equation.
Starting with the slope:
Substitute 5 as m into the equation
y=5x+b
Now for the y intercept:
As stated before, b is the value of y at the y intercept; in this case, b is equal to 3
Substitute 3 as b into the equation.
y=5x+3
Hope this helps!

I WILL GIVE BRAINIEST!!!! Help!!!! 4. A stone nudged off the Royal Gorge Bridge near Cañon City, Colorado, falls 1053 feet before
hitting water. Because its speed increases as it falls, the distance it travels each second
increases. During the first second, it drops 16 feet. During the next second, it drops an
additional 48 feet. During the third second, it drops another 80 feet. The distances traveled
each second form an arithmetic sequence:
16, 48, 80, ...
Part I: How far does the stone fall during the 5th second? Find and use the explicit formula.
a. What is the first term of the sequence?
b. What is d, the common difference?
c. Write the explicit formula in function notation. Use f(n) = f(1) + (n - 1)d, where f(1)
Answer:
First term = a= 16.
Common difference, d, = 32.
Answer for the fifth second is = 144 feet.
Step-by-step explanation:
This question is simply an Arithmetic Progression, AP,.
so, the 1st second represents the first term and so on.
for the common difference, you just subtract the first from the second term and confirm by subtracting the second from the third term and i got 32.
