g(t) = 2t - 2
h(t) = 2t - 5
Find g(t) + h(t)
Answer:
[tex]g(t) + h(t) \\ (2t -2 ) + (2t - 5) \\ (4t - 7)[/tex]
(4t-7) is the right answer.
Step-by-step explanation:
g(t) = 2t - 2
h(t) = 2t - 5
g(t) + h(t)
(2t - 2) + (2t - 5)
2t - 2 + 2t - 5

I WILL GIVE BRAINLY IF RIGHT Malia drew the hexagon below what is the measure of each angle of the hexagon
A. 60 degrees
B. 90 degrees
C. 120 degrees
D. 144 degrees
Answer:
120 Degrees
Step-by-step explanation:
A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.
Simplify the expression. Explain each step.

what’s their intercepting points
Answer:
2,-5
Step-by-step explanation:
you take two steps every hour how long would it take to walk 20 miles
Answer:
21120 hours long
Step-by-step explanation:
42240=20 miles
42240/2=21120h
Answer:
200 hours (yes, very long)
Step-by-step explanation:
You take about 2,000 steps a mile. So, you have to multiply 2,000 by 20 which is 40,000. Then, you have to divide 40,000 by 20. Lastly, you will end up with 200 hours as your answer.

Answer:
a) 96m
b) 2 m/s^2
Step-by-step explanation:
The distance travelled in a velocity time graph as shown in the image is the area of the shape. As such, considering the first 14 seconds, the distance covered will be computed by finding the area of the shape.
Note that the shape to be considered ends t the 14 seconds mark. This shape is a trapezium. The area of a trapezium is given as
A = 1/2(a + b) h
where a and b are the parallel sides of the trapezium and h is the height As such, the distance covered in the first 14 seconds
= 1/2 (14 + 10) * 8
= 4 * 24
= 96m
The acceleration after 4 seconds
Acceleration is the rate of change of velocity with time, at time 0 second, the velocity is also 0 but at time 4 seconds, the velocity is 8 m/s hence, the acceleration after 4 seconds
= 8/4
= 2 m/s^2

Does the system have no solution?
Answer:
[tex]\mathrm{A)\:}-6[/tex]
Step-by-step explanation:
Notice that in the second equation, the coefficient of [tex]y[/tex] is [tex]2[/tex] times greater than in the first. Therefore, by making the coefficient of [tex]x[/tex] in the second equation [tex]2[/tex] times greater than in the first, it's impossible to only isolate one variable.
Therefore, when [tex]a=-3\cdot 2=\fbox{-6}[/tex], there are no solutions to this system.

X^3 + 4x^2 - 11x - 30 = (x+2) (x-3) (x+5)=0
Answer:
STEP 1
Equation at the end of step 1
(((x3) - 22x2) - 11x) + 30
STEP 2
Checking for a perfect cube
2.1 x3-4x2-11x+30 is not a perfect cube
Trying to factor by pulling out :
2.2 Factoring: x3-4x2-11x+30
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -11x+30
Group 2: x3-4x2
Pull out from each group separately :
Group 1: (-11x+30) • (1) = (11x-30) • (-1)
Group 2: (x-4) • (x2)

To find:
The simplified form of given expression.
Solution:
We have,
[tex]{\dfrac{2}{5}k-\dfrac35+\dfrac{1}{10}k}[/tex]
On combining like terms, we get
[tex]=\left(\dfrac{2}{5}k+\dfrac{1}{10}k\right)-\dfrac{3}{5}[/tex]
Taking LCM in the parenthesis, we get
[tex]=\left(\dfrac{4k+k}{10}\right)-\dfrac{3}{5}[/tex]
[tex]=\left(\dfrac{5k}{10}\right)-\dfrac{3}{5}[/tex]
[tex]=\dfrac{k}{2}-\dfrac{3}{5}[/tex]
Therefore, the simplified form of the given expression is [tex]\dfrac{k}{2}-\dfrac{3}{5}[/tex].

what is the unit rate of $52.5 7h
Answer:
= 7.5 USD per hour
Step-by-step explanation:
This is a fraction equal to
52.5 USD ÷ 7 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 7
[tex]\frac{52.5}{7}[/tex]= 7.5 USD per hour
Let the Universal Set , S, have 132 elements . A and B are subsets of S. Set A contains 63 elements and Set B contains 35 elements . If the total number of elements in either A or B is 89 , how many elements are in A but not in B?
Answer:
8 elements
Step-by-step explanation:
From the question given above, the following data were obtained:
Universal set (S) = 132
Set A = 63
Set B = 35
n(AuB)ᶜ = 89
n(A but not in B) =?
Next, we shall determine the number of elements common to both set A and Set B. This can be obtained as follow:
Let the number common to both set A and B be x i.e
(AnB) = x
nA = 63
nB = 35
n(AuB)ᶜ = 89
Universal set (S) = 132
S = nA + nB + n(AuB)ᶜ – (AnB)
132 = 63 + 35 + 89 – x
132 = 187 – x
Collect like terms
132 – 187 = – x
– 55 = – x
Divide both side by –1
x = –55 /–1
x = 55
Thus, the number of elements common to set A and B is 55.
Finally, we shall determine the number of elements in A but not in B as follow:
nA = 63
n(AnB) = 55
n(A but not in B) =?
n(A but not in B) = nA – n(AnB)
n(A but not in B) = 63 – 55
n(A but not in B) = 8
Thus, 8 elements are in set A but not in set B.

a ream (500sheets) of paper is 8cm thick how thick is a pile of 1200sheets
Answer:
19.2cm
Step-by-step explanation:
You can solve with a proportion because all sheets of paper are the same thickness
[tex] \frac{500}{8} = \frac{1200}{x} [/tex]
[tex]x = \frac{1200 \times 8}{500} [/tex]
x = 19.2cm
