Rewrite this equation in Slope Intercept form and
solve the equation at x = -1. Show your work.
2x + y = 6
Answer:
y = -2x+6
y=8 when x = -1
Step-by-step explanation:
2x + y = 6
Slope intercept form is y = mx+b where m is the slope and y is the intercept
Solve for y
Subtract 2x from each side
y = -2x+6
The slope is -2 and the y intercept is -6
Let x = -1
y = -2(-1) +6
y = 2+6
y=8
(-1,8)
Answer:
y = -2x + 6
y = 8
Step-by-step explanation:
Rewrite this equation in Slope Intercept form
2x + y = 6
Subtract 2x from both sides
y = -2x + 6
------------------------------
solve the equation at x = -1
y = -2(-1) + 6
y = 2 + 6
y = 8

If g(x)= x+2/x-2 and h(x) = 4 - X, what is the value of (GoH)(-3)?
A.) 8/5
B.) 5/2
C.) 15/2
D.)18/5
Answer:
A. 8/5
Step-by-step explanation:
please be careful when typing the question. you made a mistake here (you wrote "x+2" instead of "x+1"). luckily you have provided also the screen shot.
the used symbolism of a composite function is nothing else than asking for
g(h(x)) for x=-3.
so, first we need to calculate h(-3) = 4 - -3 = 7
then we take that result as argument for g : g(7) = 8/5
so, altogether
g(h(-3)) = g(7) = 8/5
we can do this generically for x by substituting x in g by the expression of h
g(h(x)) = ((4-x) + 1) / ((4-x) - 2) = (5-x)/(2-x)
for x = -3 this gives (5- -3)/(2- -3) = 8/5
The value of the composite function (g o h) (-3) is 9/5.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
First, we need to find the composition g o h, which means we need to substitute h(x) into g(x), so that:
(g o h)(x)
= g(h(x))
= g(4 - x)
= [(4 - x) + 2] / [(4 - x) - 2]
= (6 - x) / (2 - x)
Now, we can find (g o h)(-3) by substituting x = -3 into the expression above, which gives:
(g o h)(-3)
= (6 - (-3)) / (2 - (-3))
= 9 / 5
Therefore,
The value of (g o h)(-3) is 9/5.

Find two integers whose sum is 5 and product is -66 TWO INTEGRES
NOT 1 TWO
Answer:
-6 and 11
Step-by-step explanation:
The only factors of 66 are 11, 6, 2 and 3
11*6 is the only pair whose product is 66
The difference betwen 11 and 6 is 5
11 must be positive and 6 negative since the sum is positve
sofia uses 8 gallons of gas to drive 204 miles. at the same rate, How many miles can sofia drive using 18 gallons of gas?
Answer:
Sophia can drive 3672 miles using 18 galloons of gas.
Step-by-step explanation:
204 x 18 = 3672.
Calculate miles per gallon by dividing the miles she drove you the gallons used:
204/8 = 25.5 miles per gallon.
Now multiply miles per gallon by gallons:
25.5 x 18 = 459 miles
Answer: 459 miles

Find the value of A
Answer:
a = 5
Step-by-step explanation:
Angles A and B are the same at 45, a and b are also the same
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.
sin(A)/a = sin(B)/b = sin(C)/c
Substitute the known values into the law of sines to find a.
SinA / a = sin(90) / 5√2
a = 5

5) If (x - 5) is a factor of 2r3 - 7px + (p - 12),
find the value of p.
{ANS: p = 7)
Answer:
the value of p is 7
Step-by-step explanation:
Given function;
f(x) = 2x³ - 7px + (p - 12)
factor of the given function = x - 5
Apply remainder theorem to solve for p
f(x - 5) = 0
x - 5 = 0
x = 5
f(5) = 2(5)³ - 7p(5) + (p - 12) = 0
2(125) - 35p + p - 12 = 0
250 - 34p - 12 = 0
238 - 34p = 0
34p = 238
p = 238/34
p = 7
Therefore, the value of p is 7

Find the surface area and volume of each cylinder:
a) Radius = 5 cm, height = 7.5 cm.
b) Diameter = 7 inches, height = 5 inches, state your answer in terms of .
Cylinder A -
Surface Area:
A = 2πrh + 2πr^2
A = 2 · π · 5 · 7.5 + 2 · π · 25 ≈ 392.69908
A = 392.7 cm^2
Volume:
V = πr^2h
V = π · 25 · 7.5 ≈ 589.04862
V = 589 cm^3
Cylinder B -
Surface Area:
A = 2πrh + 2πr^2
A = 2 · π · 3.5 · 5 + 2 · π · 12.25 ≈ 186.92476
A = 186.9 cm^2
Volume:
V = πr^2h
V = π · 12.25 · 5 ≈ 192.42255
V = 192.4 cm^3
Answer:
a) surface area: 125pi volume: 187.5pi
b) (i dont know what you mean by "in terms of ." so ill give both)

a) surface area is this
2pirh+2pir^2
plug it in..
2pi(5)(7.5)+2pi(5)^2
simplify...
75pi+50pi
125pi
volume is this
pir^2h
plug it in...
pi(5)^2(7.5)
simplify...
187.5pi
b is basically same steps.
