Evaluate the function when x = 5: h(x) = 3x + 5
Answer:
h(x)=20
Step-by-step explanation:
x=5
3(5)+5
15+5
20
Hope this helps!
Answer:20
Step-by-step explanation:
Hello!
So first you want to plug in 5 to all of the x
h(5) = 3(5) + 5
No you want to do 3(5)
3(5) = 15
h(5) = 15 + 5
Now you add 15 + 5
15 + 5 = 20
h(5) = 20
So your answer is 20

find the slope (m) and y -intercept (b) of the equation in standar form 2x-3y=6
Answer:
m = [tex]\frac{2}{3}[/tex] , b = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Given
2x - 3y = 6 ( subtract 2x from both sides )
- 3y = - 2x + 6 ( divide all terms by - 3 )
y = [tex]\frac{2}{3}[/tex] x - 2 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex] and y- intercept b = - 2
Answer:
y- intercept is (0, -2)
slope is 2/3
Step-by-step explanation:
find 2 points on the line:
2x-3y=6
1/2*(6+3y) =x
if y is 2, x is 6 ((6,2))
if y is 4, x is 9 ((9, 4))
y-intercept is when x = 0.
0-3y=6
y=-2
slope is (y2-y1)/(x2-x1): choose y2 and the corresponding x-coordinate is x2. then the others are the 1's. let's use 4 as y2 which means:
x2 = 9
x1 = 6
y1 = 2
then plug in and solve.
(4-2)/(9-6)
= 2/3
m = 2/3
Hope this helps!

We don't know the value of the number, so we call it x.The quotient of a number and negative five is:[tex]\frac{x}{-5} = -\frac{x}{5}[/tex]
One less than the quotient is:[tex]1 - (-\frac{x}{5}) = 1 + \frac{x}{5}[/tex]
--------------------------------
Supposing this is equals to 5.[tex]1 + \frac{x}{5} = 5[/tex]
[tex]\frac{x}{5} = 4[/tex]
[tex]x = 5 \times 4 = 20[/tex]

An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each. Mrs. Tran spent a total of $93 on bandanas at this store. How many cotton bandanas did Mrs. Tran buy
Given :
An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each.
Mrs. Tran spent a total of $93 on bandanas at this store.
To Find :
How many cotton bandanas did Mrs. Tran buy.
Solution :
Let, number of cotton and silk bandanas buys are x and y respectively.
So, 7x + 11y = 93
x = (93 - 11y)/ 7
Putting y = 1 , x = 82/7 ( not possible since x can only be positive integer )
Putting y = 4 , x = 7
Therefore, Mrs . Tran will buy 7 cotton bandanas.
Hence, this is the required solution.
what is x in 9x + 89 = 161
Answer:
The answer is x=8
Step-by-step explanation:
hope that helps
9x+89=161

9x=72
9x/9=72/9
x=8
Answer:
x = 8
Step-by-step explanation:
We just need to solve for x!
Here is a step-by-step process:
9x + 89 = 161
Subtract 89 from both sides
9x = 72
Divide both sides by 9
x = 8

The lenngths of the sides of the triangle are in the extended ratio 8:9:10. The primeter of the triangle is 108 cm.What are the lengths of the sides?
The lengths of the sides of the triangle in cm are____?
Answer:
The lengths of the sides of the triangle in cm are 32 cm, 36 cm and 40 cm
Step-by-step explanation:
The lengths of side of the triangle are in ratio 8:9:10
Perimeter of triangle = 108 cm
We need to find length of sides of triangles.
The formula used is: [tex]Perimeter \ of \ triangle = Sum \ of \ all \ sides \ of \ triangle\\[/tex]
The length of side of triangle can be expressed as:
First side= 8x
Second Side =9x
Third Side=10x
So, finding x and then calculate length of each side
[tex]Perimeter \ of \ triangle = Sum \ of \ all \ sides \ of \ triangle\\\\108=8x+9x+10x\\108=27x\\x=\frac{108}{27}\\x=4[/tex]
So, value of x = 4
The length of sides of triangle will be found by putting value of x at each side.
First side= 8x = 8*4 = 32 cm
Second Side =9x= 9*4= 36 cm
Third Side=10x = 10*4=40 cm
So, The lengths of the sides of the triangle in cm are 32 cm, 36 cm and 40 cm

Find the probability that x <-3
Answer:
Step-by-step explanation: if you want to obtain the probability that x [tex]\leq[/tex]-3 , then you need to add the probability for the cases x=-3 and x=-5.
p=0.13+0.17= 0.3
answer=0.3
The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
As per the given probability distribution.
The probability distribution is the probability of different cases.
In cases the probability adds thus,
P(x ≤ - 3) = P (x = -3) + P(x = -5)
⇒ 0.13 + 0.17 = 3
Hence "The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30".

The diagram to the right of airport runaways intersection shows two parallel runways. A taxiway crosses both runways use the diagram to answer the question.
Answer:
m<4 is the measurement of 20°
and m<1 is the measurement of 33°
and in order to get 127° is to subtract 180° by 127° then that gives you 53° then you ether divide 53° by 180° or, you divide 53° in half, which gives you 33° for measurement 1™ and measurement 4™ gives you 20°
Step-by-step explanation:
The sum of angles m∠1 and m∠4 is 254°.
What is an angle?When two lines meet at a point, the geometrical figure that is formed is called an angle.
Here the taxiway crosses two parallel airplane runways.
Now, the m∠8 = m∠4 (these are corresponding angles)
Again, m∠4 = m∠1 (these are opposite angles)
Therefore, sum of angles m∠1 and m∠4
= (m∠1 + m∠4)
= (m∠8 + m∠8)
= 2 × m∠8
= 2 × 127°
= 254°
