Answer:
My answer is = 9 cannot equal 12. There are no variables present in this equation, so what are you solving for?
Step-by-step explanation:
On the right you would use distributive property and on the left you would just simply add and subtract.
However, you cannot equal it to zero either because there are no variables nor exponents.
The sum of three numbers is 107. The second number is 7 less than the first. The third number is 3 times the second. What are the numbers?
Answer:
27, 20, 60
Step-by-step explanation:
We use the equation
(x) + (x - 7) + (3 * (x - 7)) = 107
= x + x - 7 + 3 * (x - 7) = 107
= 2x - 7 + 3(x - 7) = 107
Add 7 on both sides
= 2x + 3(x - 7) = 114
Expand the 3
= 2x + 3x - 21 = 114
= 5x - 21 = 114
Add 21 on both sides
= 5x = 135
Divide 5 on both sides
= 5x/5 = 135/5
= x = 27
Plug the functions in
(27) + (27 - 7) + (3 * (27-7)) = 107
You would get
27 + 20 + 60 = 107, therefore the numbers are 27, 20, 60

Equation of the Line
The standard form of the equation of a line is shown below:
Ax+By=C
And the slope-intercept form is:
y = mx + b
Where m is the slope and b is the y-intercept.
If we wanted to convert from the first form to the second we will perform the following operations:
Subtract Ax:
By = -Ax + C
Divide by B:
y = -A/Bx+C/B
The coefficient of x is -A/B (fill the blank with that text) and the y-intercept is C/B (again, fill in the blank)
The slope m is the coefficient of x, m=-A/B and it can be found it you divide the opposite of A by B. The selected option is correct.
The y-intercept is the division of C by B. Again, the selected option is correct.

3 .What is the slope of the equation -8x+4y=10?
A.4
B.-8
C.2
D.10
Answer:
1. B
2. C
3. C
Step-by-step explanation:
Answer:
1. D: 6 2.A:y=0.1x + 2 3.C
Step-by-step explanation:
1. In y = mx + b, b represents the y-intercept. The equation is alreayd in y = mx +b, so we can see that 6 is b, making it the y-inetrcept.
2. A is the only one written in slope intercept form, or y = mx + b.
3. -8x + 4y = 10 written in slope intercept form is y = 2x + 5/2. The slope is shown by 2.
Solve the formula for the specified variable.
W=X+Xyz for y
We have to isolate y.
W=X+Xyz
Subtract X from both sides. Doing so, we get the following: W - X = Xyz.
We now simply divide both sides by Xz to isolate y.
(W - X)/Xz = y
Done.
factor of 7+14x+7x 2
Answer:
7(3+2x)
Step-by-step explanation:
z = 24a - 2b
solve for a
Answer:
a= (Z + 2b)/24
Step-by-step explanation:
given:
Z = 24a - 2b
to solve for a, we will try to move "a" to one side of the equation and all other terms to the other side:
Z = 24a - 2b (add 2b to both sides)
Z + 2b = 24a -2b +2b
Z + 2b = 24a (switch sides)
24a = Z + 2b (divide both sides by 24)
a/24 = (Z + 2b)/24
a= (Z + 2b)/24

He range R and the maximum height H of a projectile fired at an inclination θ to the horizontal with initial speed v0 are given by the formulas below, where g≈32.2 feet per second per second is the acceleration due to gravity. Complete parts A and B. R= 2v20sinθcosθ g H= v20sin2θ 2g
Answer:
A. R=1098.7ftB. H=274.7ftStep-by-step explanation:
"The question is not complete, here is the complete question
The range R and the maximum height H of a projectile fired at an inclination θ to the horizontal with initial speed v0 are given by the formulas below, where g≈32.2 feet per second per second is the acceleration due to gravity. Complete parts A and B.
[tex]R=\frac{2v_o^2sin \theta cos \theta}{g}[/tex]
[tex]H=\frac{v_o^2sin^2 \theta}{2g}[/tex]
A. Find the range R if the projectile is fired at an angle 45° to the horizontal with an initial speed of 190 ft per second
B. Find the maximum height H if the projectile is fired at angle 45° to the horizontal with an initial speed of 190 ft per second"
Solution
A. given the expression for Range R
substitute v= 190 ft/sec and ∅=45°
[tex]R=\frac{2(190)^2sin(45) cos(45)}{32.2}\\\\R=\frac{72200*0.7*0.7}{32.2}\\\\R=\frac{35378}{32.2} \\\\R=1098.7ft[/tex]
B. . given the expression for maximum height
substitute v= 190 ft/sec and ∅=45°
[tex]H=\frac{v_o^2sin^2 \theta}{2g}\\\\H=\frac{190*190*0.7*0.7}{2*32.2}\\\\H=\frac{17689}{64.4}\\\\H=274.7ft[/tex]

Find all points (x, y) where the functions f(x), g(x), h(x) have the same value: f(x) = 2^(x−5) + 3, g(x) = 2x − 5, h(x) = 8/x + 10
quickly please!!!!
Answer:
The point where f(x), g(x), and h(x) have the same value is (8, 11)
Step-by-step explanation:
The points where g(x) and h(x) have the same value is given as follows;
2x - 5 = 8/x + 10
2x² - 15x - 8 = 0
Using an online tool, we have;
(x - 8)(2x + 1) = 0
x = 8 or x = -1/2
∴ g(x) and h(x) = 11 or y = -6
For x = 8, we have;
f(x) = 2^(x - 5) + 3 = 2^(8 - 5) + 3 = 2^3 + 3 = 11
For x = -1/2, we have;
f(x) = 2^(-1/2 - 5) + 3 = 3.022
Therefore, the point where f(x), g(x), and h(x) have the same value is (8, 11), therefore, for x = 8, f(x) = g(x) = h(x) = 11.
