−5x+6=−4(2x−1)
x=−14/3
x=−10/13
x=−2/3
Answer:
-2/3
Step-by-step explanation:
First, distribute, -4(2x - 1) is -8x + 4. Next, do the opposite of the sign for the variable, since -8x can be written as - 8x, do the opposite sign, which is addition. -5 + 8 and -8 + 8. Add on both sides. Now you have 3x + 6 = 4. Then subtract 6 by 4. You'll get -2. The denominator is the number that has the variable. So now the equation will be 3x/3 = -2/3. You can turn -2/3 into a decimal, but it-s fine like that.
[tex]\sf 45-4x=75-6x[/tex]
[tex]\sf \longmapsto45 - 4x = 75 - 6x[/tex]
[tex]\sf \longmapsto45 - 75 =- 6x + 4x[/tex]
[tex]\sf \longmapsto -30 =- 2x[/tex]
[tex] \sf \longmapsto \frac{ 30}{2} = x [/tex]
[tex]\sf \longmapsto 15 = x[/tex]
[tex]\sf \longmapsto \: x ≈15[/tex]
=> 45 - 4x = 75 - 6x
=> 45 - 75 = -6x + 4x
=> -30 = -2x
=> x = 30/2
=> x = 15

Geometry haha, I have no idea how to do this
Answer:
∠DOB=108°
Step-by-step explanation:
∠AOD=∠COB=y
∠AOC=3.5y-y-y
=1.5y
3.5y+1.5y=360° (angles at a pt)
5y=360°
y=360°÷5
=72°
1.5y=72°×1.5
=108°
Hence, ∠DOB=108°.
Answer:
108
Step-by-step explanation:
Call the angle facing east x. The angle facing west is also x. The angle facing north, (thus the angle facing south) is given and is y. You can tell that if you take y twice and x once you get 3.5y, and it's easy to spot that x+y=180. Rest is simple math as in the image added - sorry for the handwriting. With simple algebra (you substitute back and forth) you should get x = 108 degrees.
What is the solution to the system of equations below?
x + 3 y = 15 and 4 x + 2 y = 30
(6, 3)
(3, 6)
(7, –6)
(–6, 7)
Answer:
Step-by-step explanation:
For x+3y=15
Take (6,3) and substitute the points:
6+3(3)=15
6+9=15
15=15
For 4 x + 2 y = 30 and substitute the points:
4(6)+2(3)=30
24+6=30
30=30
So, (6,3) is the solution of the given system of equations.

Select the equation of a line in slope-intercept form that passes through (-2, 2) and is perpendicular to the graph of y=1/2 x-2.
Answer:
y=-2x-2
Step-by-step explanation:
since the line is perpendicular to y=1/2x - 2, the slop is -1/(1/2)=-2. so we have y=-2x+b. now plug in the point given: 2= -2(-2)+b, 2=4+b, b=-2, y=-2x-2

for each of the solutions of the equations find two consecutive integers between which the solution is located.
x²=3
Using squares of integers numbers, it is found that the solution of the equation is located between the integers x = 1 and x = 2.
The equation given is:
[tex]x^2 = 3[/tex]
The solution of the equation given is:
[tex]x = \sqrt{3}[/tex]
The squares of the integers numbers until the square root of 3 are:
[tex]1^2 = 1[/tex]
[tex]2^2 = 4[/tex]
Since [tex]1 < 3 < 4[/tex], the square root of 3, which is the solution to the equation, is located between the integers x = 1 and x = 2.

y∝1/√x If y=5
when x=36 find,
x when y=3
Answer:
x = 100.
Step-by-step explanation:
y ∝ 1/√x
y = k /√x where k is a constant.
When x = 36 y = 5 so we have:
5 = k / √36
5 = k / 6
k = 30
So we have the relation:
y = 30 /√x
When y = 3
3 = 30/ √x
√x = 30/3 = 10
x= 100.

a private and a public university are located in the same city. for the private university, 1046 alumni were surveyed and 653 said that they attended at least one class reunion. for the public university, 791 out of 1327 sampled alumni claimed they have attended at least one class reunion. is the difference in the sample proportions statistically significant at the 1% level?
Using the z-distribution, it is found that since the absolute value of the test statistic is less than the critical value, the difference in the sample proportions is not statistically significant at the 1% level.
At the null hypothesis, we test if the proportions are the same, that is, their subtraction is 0, hence:
[tex]H_0: p_1 - p_2 = 0[/tex]
At the alternative hypothesis, it is tested if they are different, that is, their subtraction is not 0, hence:
[tex]H_1: p_1 - p_2 \neq 0[/tex]
The proportions and their respective standard errors are given by:
[tex]p_1 = \frac{653}{1046} = 0.6343, s_1 = \sqrt{\frac{0.6343(0.3657)}{1046}} = 0.0149[/tex]
[tex]p_2 = \frac{791}{1327} = 0.5961, s_2 = \sqrt{\frac{0.5961(0.4039)}{1327}} = 0.0135[/tex]
For the distribution of the difference, the mean and the standard error are given by:
[tex]\overline{p} = p_1 - p_2 = 0.6343 - 0.5961 = 0.0382[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0149^2 + 0.0135^2} = 0.0201[/tex]
The test statistic is:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
In which [tex]p = 0[/tex] is the value tested at the null hypothesis.
Hence:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
[tex]z = \frac{0.0382 - 0}{0.0201}[/tex]
[tex]z = 1.9[/tex]
The critical value for a two-tailed test, as we are testing if two values are different, with a significance level of 0.01, is of [tex]|z^{\ast}| = 2.576[/tex]
Since the absolute value of the test statistic is less than the critical value, the difference in the sample proportions is not statistically significant at the 1% level.

Find the area of the composite figure made up of a square and a semicircle. Use 3.14 as an approximate for pi and give your nearest square inch. Enter only the number.
Answer:
200.52 in^2
Step-by-step explanation:
to find the area of a circle, you square 6 and multiply it by pi in this case 3.14.
that gives you 113.04 but because this is only a half circle, it is 56.52 in^2.
Next, you need to find the rectangle. multiply 12(length) by 12(Width) to get 144 add 144 to 56.52 to get 200.52.

What is the area of this figure?
Given :-
A figure is given to us .To Find :-
The area of the figure .Solution :-
As we can see that the given figure is made up of a parallelogram and a ∆ . As we know that the opposite sides of a parallelogram are equal . So that the base of the ∆ would be 9cm . Now ,
[tex]\longrightarrow[/tex] Area = ar(||gm ) + ar(∆)
[tex]\longrightarrow[/tex] Area = (9*5 + 1/2*8*9)cm²
[tex]\longrightarrow[/tex] Area =( 45 + 45 ) cm²
[tex]\longrightarrow[/tex] Area = 90cm²
Hence the area of the given figure is 90cm² .
