-4+5x-7=10+3x-2x. Solve for x
Answer:
-4 + 5x - 7 = 10 + 3x - 2x
5x - 3x + 2x = 10 + 4 + 7
4x = 21
x = 21/4
x = 5 1/4 or 5.25
Answer: 5=x
Step-by-step explanation:
-4+5x-7=10+3x-2x
Combine like terms:
-10+5x=10+x
Subtract 10 on both sides:
-10-10+5x=10-10+x
-20+5x=x
Subtract 5x on both sides:
-20+5x-5x=x-5x
-20=-4x
Divide -4 on both sides:
-20/-4=-4x/-4
5=x

Part a: The value of x such that the both lines are parallel to each other is (x = 12).
Part : The value of y such that the both lines are parallel to each other is (y = 108).
What is defined as the corresponding angles?Corresponding angles are generated when two parallel lines have been intersected by a transversal. The definition of corresponding angles states that when two parallel lines intersect with a third, the angles that take up the same relative position at every intersection are said to be corresponding angles to one another.In the given figure;
Part a: For making the lines w and t parallel to each other; their corresponding angles must be equal.
Thus,
4x + 60 = 9x
Solving;
9x - 4x = 60
5x = 60
x = 12
Thus, the value of x for which both lines w and t are parallel is 12.
Part b: For making the lines u and v parallel to each other; their corresponding angles must be equal.
Thus, 9x = y
Put x = 12.
y = 9×12
y = 108.
Thus, the value of y for which both lines u and v are parallel is 108.

Answer:
Cannot be determined
Step-by-step explanation:
You get that angles 4 + 5 and 2 + 1 are equal to 180 each. We still have angle 3 left over, and that angle could be anything, so it cannot be determined
Answer:
well 4+5=180°, 1+3=180°, that's 360, so I guess can't be determined since there's still another angle???

Solve 6 + 1/4a = 3 for a.
Answer:
a= -12
Step-by-step explanation:
Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent.)
Answer:
Growth rate is -0.25
Growth factor is 0.75
Step-by-step explanation:
The general form of an exponential equation is;
y = a(1 + r)^x
Where a is the initial value
r is the growth rate
For x = 3; we have
168.75 = 400(1 + r)^3 •••• (i)
For x = 2, we have
225 = 400(1 + r)^2 •••••(ii)
Divide i by ii
That will be;
168.75/225 = 1 + r
1 + r = 0.75
r = 0.75-1
r = -0.25
The growth rate is -0.25
The growth factor is 1-0.25 = 0.75
Find the value of “X”
Answer:
x = 27
Step-by-step explanation:
(3x - 17) + (x + 40) + (2x - 5) = 180
6x = 17 - 40 + 5 + 180
6x = 162
x = 27
Answer:
The value of x is 27°.
Step-by-step explanation:
Given that total angles inna triangle is 180°. In order to find the value of x, you have to add up all the expressiobs to form 180° :
(3x - 17)° + (x + 40)° + (2x - 5)° = 180°
6x + 18° = 180°
6x = 180° - 18°
6x = 162°
x = 162° ÷ 2
x = 27°

For the cubic x^3 + 7x^2 + 13x + 3 has only one rational zero, x=-3. Use polynomial long division to show that the remainder is zero when dividing the cubic by x+3. Then use the quadratic formula to find the other two (irrational) zeroes.
The two irrational roots of the cubic equation are - 2 + √3 and - 2 - √3, respectively.
How to find the two remaining zeroes of the cubic equation
In this problem we find the definition of a cubic equation, of which one root is known and we need to find the two missing roots. By algebraic handling, the cubic equation is:
f(x) = x³ + 7 · x² + 13 · x + 3
f(x) = (x³ + 3 · x²) + (4 · x² + 12 · x) + (x + 3)
f(x) = x² · (x + 3) + 4 · x · (x + 3) + (x + 3)
f(x) = (x² + 4 · x + 1) · (x + 3)
Then, the roots of x² + 4 · x + 1 are found by using the quadratic formula:
x² + 4 · x + 1 = (x + 2 - √3) · (x + 2 + √3)

SOMEONE HELP ME PLEASE ILL GIVE BRAINLY
Answer:
Step-by-step explanation:
In order to determine the information you're being asked for, you need to complete the square on that quadratic. The first step is to move the constant over to the other side of the equals sign:
[tex]x^2-2x=3[/tex]
Here would be the step where, if the leading coefficient isn't a 1, you'd factor it out. But ours is a 1, so we're good there. Now take half the linear term (the term with the single x on it), square it, and add it to both sides. Our linear term is a -2. Half of -2 is -1, and -1 squared is +1. We add +1 to both sides giving us this:
[tex]x^2-2x+1=3+1[/tex]
Now we'll clean it up a bit. The right side becomes a 4, and the left side is written as its perfect square binomial, which is the whole reason we did this. That binomial is
[tex](x-1)^2=4[/tex] (set equal to the 4 here). Now we'll move the 4 back over and set the whole thing back equal to y:
[tex]y=(x-1)^2-4[/tex]
From this it's apparent what the vertex is: (1, -4),
the axis of symmetry is x = 1, and
the y-intercept is found by setting the x's equal to 0 in the original equation and solving for y. So the y-intercept is (0, -3).

Jeremy bakes two pans of brownies that are the same size. One pan has nuts in it and the other pan does not. He cuts the pan with nuts into 8 equal pieces. He cuts the pan without nuts into 16 equal pieces. His friends eat 2 brownies with nuts and 3 brownies without nuts. Did they eat more of the brownies with nuts or without nuts?
Answer:
The answer is "[tex]\frac{2}{8} > \frac{3}{16}[/tex] So, they eat more brownies with nuts".
Step-by-step explanation:
In the given question, the two browny pans of equal size are baked by Jeremy. There is indeed a saucepan with nuts in it, not the other pan. He split the pot into eight equal chunks with nuts. He slices the pan into 16 equal parts without nuts. His mates eat 2 nuts brownies and three nut-free brownies. They eat more nuts and brownies [tex]\frac{2}{8} > \frac{3}{16}[/tex] eat more.

The line segment is AB.
The equation is y =
Answer:
The equation is:
[tex]y = -x + 7[/tex]
Step-by-step explanation:
Given the endpoints of a side of a rectangle
A(1, 6)B(6, 1)Finding the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:6\right),\:\left(x_2,\:y_2\right)=\left(6,\:1\right)[/tex]
[tex]m=\frac{1-6}{6-1}[/tex]
[tex]m=-1[/tex]
Using the point-slope form of a line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -1 and the point (1, 6)
[tex]y - 6 = -1 (x - 1)[/tex]
[tex]y - 6 = -x + 1[/tex]
[tex]y = -x + 1 + 6[/tex]
[tex]y = -x + 7[/tex]
Thus, the equation is:
[tex]y = -x + 7[/tex]

Answer:
12 days
Step-by-step explanation:
Let the amount of work be x.
John:
6 days = x
1 day = [tex]\frac{1}{6}[/tex]x

4 days = x
1 day = [tex]\frac{1}{4}[/tex]x
Marsha:
1 day = [tex]\frac{1}{4}[/tex]x - [tex]\frac{1}{6}[/tex]x
= [tex]\frac{6}{24}[/tex]x - [tex]\frac{4}{24}[/tex]x

Step-by-step explanation:
This is a right triangle, which we know because of the square in the corner of the triangle. We can use the right triangle trigonometric ratios.
[tex]sin( \theta) =opposite/hypotenuse[/tex] and [tex]cos (\theta) = adjacent /hypotenuse[/tex] and [tex]tan (\theta)=opposite/adjacent[/tex]
First, identify each side of the triangle as adjacent, opposite, or hypotenuse, relative to the 68 degree angle.
The x is next to, or adjacent, to the angle. The 24 is opposite. We are not given the hypotenuse.
[tex]adjacent= x \\opposite= 24 \\hypotenuse= unknown[/tex]
Since we have the adjacent and opposite, we must use tangent.
[tex]tan (\theta)=\frac{opposite}{adjacent}[/tex]
Substitute the values in. The theta (θ) is the angle.
[tex]tan (68)=\frac{24} {x}[/tex]
Solve for x. One way is by cross multiplying.
[tex]\frac{tan(68)}{1}=\frac{24}{x}[/tex]
Multiply the 1st numerator by the 2nd denominator. Then, multiply the 1st denominator by the 2nd numerator.
[tex]tan (68)*x=1*24[/tex]
[tex]tan(68)*x=24[/tex]
Evaluate tan(68) using a calculator.
[tex]2.47508685*x=24[/tex]
Divide both sides of the equation by 2.47508685. This will isolate the variable x. ( We divide because multiplication is occurring between 2.47508685 and x, and division is the inverse of multiplication).
[tex]\frac{2.47508685*x}{2.47508685}=\frac{24}{2.47508685}[/tex]
[tex]x=\frac{24}{2.47508685}[/tex]
[tex]x=9.69662943[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round up. The 6 becomes a 7.
[tex]x \approx 9.7[/tex]
In this right triangle, x is equal to about 9.7
