Answer: -1.65 ≥ x
Step-by-step explanation:
We usually express "equal to or greater than" by using the symbol ≥.
And we set up the inequality by looking at the word description, then we have:
-11.3 ≥ -4.7 + 4x plus 4.7 on both sides.
-6.6 ≥ 4x divide 4 on both sides.
-1.65 ≥ x

Solve the following quadratics equation for all values of x in simplest form
9(3x - 7) ^2= 16
Answer:
x= 17 /9 or x= 25 /9
Step-by-step explanation:
9(3x - 7) ^2= 16
9(3x - 7) ^2-16= 0
as we know that (a-b)^2=a^2-2ab+b^2
9((3x)^2-2(3x)(7)+(7)^2=0
solving this we got the below equation
81x2−378x+425=0
By Factorizing the equation
(9x−17)(9x−25)=0
9x−17=0 or 9x−25=0
x= 17 /9 or x= 25 /9

To the nearest tenth of a percent, what percent of the 7th grade students were in favor of wearing school uniforms?
A. 19.2%
B. 41.3%
C. 42.9%
D. 57.1%
Answer:
C. 42.9%
Step-by-step explanation:
They say out of 7th grade so we need the total 7th graders which is 112 and they say in favor so then we take 48 and divide the two 48/112 which gives us a decimal so we then multiply it by 100 to get the percent.
48/112= 0.429
0.429(100)= 42.9%
The percent of the 7th grade students were in favor of wearing school uniforms is 42.9%
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
Total students in 7th grade = 112
Students who favor school uniforms = 48
So, the percent of the 7th grade students were in favor of wearing school uniforms is
= 48 /112 x 100
= 0.4285 x 100
= 42.85 %
= 42.9%
Thus, the required percentage of student is 42.9%.

Find the x- and y- intercepts of the equation -x+5y=10.
Answer:
X Intercept: (-10,0), Y Intercept: (0,2)
Step-by-step explanation:
Well, firstly you need to rewrite the equation to make it easier. After rewriting it you have the equation y=x/5+2 by adding the x to the right side and dividing everything by 5. Now simply plug in your zeroes in their respective places. For the x intercept, your y value must equal 0 so we have the equation 0=x/5+2. After solving it, x must be -10 in order for our y value to be 0 getting us for the x intercept (-10,0). For the y intercept, your x value must equal zero so you simply subsitute zero in the equation for x which I will do here: y=0/5+2. If our x value is zero, consequently, our y value will be 2 getting us for the y intercept, (0,2).

use the distributive property to multiply -7(-p+6)
Answer:
-7(-p+6)
Step-by-step explanation:
Answer:
-7(-p+6)
Step-by-step explanation:
Answer:
[tex]7p-42[/tex]
Why:
To use the distributive property, you multiply all things within the parantheses by the -7 (in this case). To Multiply -p and -7, remember that a negative times a negative equals a positive, so it simply results in 7p. When you multiply -7 and 6, multiply them together and you get -42. You get [tex]7p+-42[/tex], but that's not a fully simplified equation, so get rid of the addition symbol and make the 42 positive. This expression is now fully simplfied into [tex]7p-42[/tex].
P.S. Never ever add a negative in an expression. Lots of teachers like to dock your points for doing it.

Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration.)
[tex]\frac{dy}{dx}[/tex] = 4x^1/6
Answer:
For this we can first multiply both sides by dx:
[tex]dy = 4x^{1/6}dx[/tex]
Next we can integrate both sides:
[tex]\int dy = \int 4x^{1/6}dx\\[/tex]
We can then solve both integrals to get:
[tex]y = 4(\frac{6}{7}x^{\frac{7}{6}}+C_1) = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]
We can just say the constant is C2. So the answer is
[tex]y = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]
We can also check this by differentiating both sides. We will ultimately get the equation we with. If I made any mistakes or misread something, please let me know.
Desirae made 138 cookies this week. She baked 2 more than 4 times the total she made last week. How many cookies did she bake last week?
Answer: 34 cookies baked last week
Step-by-step explanation:
138=4x-2
136=4x
34=x
Answer:
34 cookies!
Step-by-step explanation:
If we say the number of cookies that Desirae baked last week was 'x', we can make the following equation for how many she baked this week: 4x+2=138. Here are the following steps to solve for x:
4x=138-2=136
x=34
Therefore she baked 34 cookies last week.
The graph shows a line and two similar triangles. On a coordinate plane, a line goes through (0, 2) and (6, 4). A small triangle has a rise of 1 and run of 3 and a larger triangle has a rise of 2 and run of 6. What is the equation of the line? y = 3 x y = one-third x y = one-third x + 2 y = 3 x + 2
Answer:
its c / i took the test
Step-by-step explanation:
:)
The Equation of line is y= 1/3 x + 2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given-
The points through which line passes (0, 2) and (6, 4).
So, the Slope of the line,
m = (4- 2)/ (6-0)
m= 2/6
m= 1/3
and, the Equation of line is
y- 2 = 1/3 (x - 0)
y-2 = 1/3x
y= 1/3 x + 2
3y = x+ 6
