Answer:
x = -24/7
Step-by-step explanation:
To solve, you need to multiply both sides by 10 ( the GCF of 5 and 2) to get rid of the fractions. Once multiplied, you get this:
2(4x-2) + 5(1) = 5(3x+7) - 10(1)
Now, just distribute the parenthesis:
8x - 4 + 5 = 15x + 35 - 10
Now, combine like terms:
8x + 1 = 15x + 25
15x + 25 = 8x + 1 (rearranged the equation)
Subtract the x's:
7x + 25 = 1
Now solve:
7x = -24
x = -24/7
The library made a table to track the number of fiction and nonfiction books checked out for 6 days.
On the first day, 18 fiction books are checked out, and 12 nonfiction books are checked out.
Each day after 18 fiction books are checked out, and 12 nonfiction books are checked out.
Drag the numbers from the box to complete the table.
Numbers may be used once, more than once, or not at all.
Step-by-step explanation:
6 days+12 days=18
so 18 fiction books+12 non fiction=20 fiction and 10 non fiction

What two numbers... add to 6 and multiply to -27?
Answer:
Hello There. Here is Explanation How to get the answer.
Explanation: x + y = -6 �> x = -6-y
xy = 8
(-6-y)y = 8
-6y - y^2 = 8
y^2+6y+8 = 0
(y+2)(y+4) = 0
Hope It Helps! .ω.

If the chance of rain is 3/4, what is the chance it will not rain?
A)0%
B)25%
C)50%
D)75%
E)100%
The two probabilities need to equal 1
The probability it will not rain = 1 - probability of rain:
1 - 3/4 = 1/4
1/4 as a percent = 25%
The answer is B) 25%

When writing a linear equation in standard form, what other forms might you need to use?
Answer:
there are 2 other forms, point-slope form and slope-intercept form.
Step-by-step explanation:
standard is [tex]Ax + By =C[/tex]
point-slope is [tex]y-y_{1} =m(x-x_{1})[/tex]
slope-intercept is [tex]y=mx+b[/tex]
Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals
Answer:
slope: -3
y-intercept: -5
equation: y = -3x - 5
Step-by-step explanation:
The formula for slope is:
(y2 - y1)/(x2 - x1)
Let's use these coordinates:
(-1, -2)
(0, -5)
x1 = -1
x2 = 0
y1 = -2
y2 = -5
Substitute into the formula:
(y2 - y1)/(x2 - x1)
(-5 + 2)/(0 + 1)
Solve:
(-5 + 2)/(0 + 1)
-3/1
= -3
slope = -3
The y-intercept is when the x coordinate is 0.
Looking at the table, we see the coordinate (0, -5).
The y-coordinate is -5.
This means that the y-intercept is -5
y-intercept = -5
Slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept
m = -3
b = -5
Substitute:
y = mx + b
y = -3x - 5

what is the slope of the line that contains the points (-2,8) and (-2,1)
Answer:
0
Step-by-step explanation:
because -2 does not change
Answer:
Undefined
Step-by-step explanation:
To find the slope, you need the formula, y₂-y₁ divided by x₂-x₁.
That is 1-8 divided by -2-(-2), or -7 divided by 0.
Anything divided by 0 is undefined, so the answer is undefined.

What is the arc measure of minor arc AB in degrees?
Answer:
The measure of a minor arc is the measure of its central angle. The expression m AB is read as “the measure of arc AB.” The measure of the entire circle is 360°. The measure of a major arc is the difference of 360° and the measure of the related minor arc.

Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this: [tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex](the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form: [tex]ax^{2} +bx+c=0[/tex])
So, we just have to input the stuff from our equation into the formula!
[tex]x=\frac{-4+-\sqrt{32} }{2}[/tex]
Now, we can simplify the square root of 32 into 4 times the square root of 2
[tex]x=\frac{-4+-4\sqrt{2} }{2}[/tex]
And, we can divide 2 from it all!
[tex]x=-2+-2\sqrt{2}[/tex]
So, there you have it! The Answer is C, or 3.
Hope this helps!

Determine if triangles can be formed with the following side lengths:
1.) 4 cm, 7 cm, 10 cm
2.) 24 mm, 20 mm, 30 mm
Answer:
1: n=17
2: x=24 w=37
Step-by-step explanation:
1st picture: 180-108=72/2=34/2=17=n
2nd Picture: 90+19= 109
109+x+w=180
138+90=228
270-228=52
138+52+90+19=299
360-299=61
x=24 w= 37
What is the equation of the line that passes through (0, 3) and (7,0)?
y-ix-3
3
y=x+3
3
y y=-7x+3
y=-x-3
Answer:
The equation of the line in slope-intercept form is:
[tex]y=-\frac{3}{7} x+3\\[/tex]
In one of the many possible standard forms:
[tex]3\,x+7\,y=21[/tex]
Step-by-step explanation:
First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):
[tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{0-3}{7-0}=-\frac{3}{7}[/tex]
Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:
[tex]y=m\,x+b\\y=-\frac{3}{7} x+3[/tex]
And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":
[tex]y=-\frac{3}{7} x+3\\7\,y=-3\,x+21\\3\,x+7\,y=21[/tex]

Which is a possible turning point for the continuous
function f(x)?
O (-2,0)
O (0, -2)
O (2-1)
O (4,0)
Answer:
(0, -2)
Step-by-step explanation:
A turning point is a point at which the derivative changes sign from positive to negative or vice versa. Then, a turning point coincides with a relative maximum or a relative minimum (also known as local minimum and maximum).
From the table, we see that f(x) decreases from x = -6 to x = 0 and it increases from x = 0 to x = 6. Therefore, there is a minimum at (0, -2)

Answer:
Step-by-step explanation:
A) Cost of canvas = $ x
Cost of 4 canvases = 4 *x = 4x
Money left over after buying 4 canvases = $2.20
Equation: 25 - 4x = 2.2
Solution: Subtract 25 from both sides
-4x = 2.2 - 25
-4x = - 22.8
Divide both sides by (-4)
-4x/-4 = -22.8/-4
x = 5.7
B) Money in Molly's account= x
4 times of Molly's account = 4x
Equation: 4x - 2.2 = 25
Solution: 4x = 25 +2.2
4x = 27.2
x = 27.2/4
x = 6.8

What is the slope of the line that is represented by the values in the table above?
Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope, [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To calculate the slope we only require two pair of points.
Let us take: [tex](x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)[/tex]
[tex]m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5[/tex]
The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.

Which function is the inverse of function f?
f(x)=9x^2–12
Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D
a cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.
enter the height, in feet, of the cylinder in decimal from. round your answer to the nearest tenth.
Answer:
Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:
[tex]R = \dfrac{D}{2}[/tex]
So, radius, R = [tex]\frac{6}{2} \Rightarrow 3[/tex] feet
Let height of cylinder be [tex]h[/tex] feet.
Formula for volume of cylinder is given by:
[tex]V = \pi R^{2} H[/tex]
Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,
[tex]V = \dfrac{36 \pi}{5} ft^{3}[/tex]
Using formula for volume, [tex]V = \pi R^{2} H[/tex]
[tex]\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft[/tex]
Hence, Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].
