Answer:
-3y + 12
Step-by-step explanation:
Just multiply -3 by both y and -4
Answer:
-3y + 12
Step-by-step explanation:
−3(y−4)
=(−3)(y+−4)
=(−3)(y)+(−3)(−4)
=−3y+12
What is A line that a graph approaches as x or y increases, but never crosses?
Answer:
Asymptotes. The y -axis is a vertical asymptote of the graph. This means that the curve gets closer and closer to the y -axis but does not cross it. Let us consider what happens as the value of x approaches zero from the right for the equation whose graph appears above.
Step-by-step explanation:
What is the solution to the equation below? Х = 4 -3
Answer:
If there's no other variables involved.
x=1
Answer:
x = 1
Step-by-step explanation:
x = 4 - 3
4 - 3 = 1
Hence, x = 1
a. Calculate the sample proportion of respondents who have a college degree. The sample proportion of respondents who have a college degree is
Answer:
20% , based on example.
Step-by-step explanation:
Let the number of sampling respondents be = 100
If out of them 35 have low school education, 45 have high school education, 20 have college degree education.
So, sample proportion of respondents, who have college degree = No. of people who have college degree / Total sample respondents = 20 / 100 = 20% or 0.2 proportion.
Which terms are like terms?
4c, 2, 6f, -5, and 7c
Answer:
2 and -5
4c and 7c
Step-by-step explanation:
2 and -5 have no coefficient
4 and 7 have the same coefficient which in this case is c.
therefore the two pairs are like terms.

Question 7 (3 points) What is the value of the missing side? Round to the nearest hundredth
Answer:
26.03
Step-by-step explanation:
x/ sin 90° = 19/ sin 47°
x = 19×sin90°/sin 47°
= 19 / 0.73
= 26.03

Need help with inscribed angles If M
Given:
In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and [tex]m\angle BCD=30^\circ[/tex].
To find:
The [tex]m\angle AOB[/tex].
Solution:
If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.
We have, DC is parallel to BA and BC is the transversal line.
[tex]\angle OBA\cong \angle BCD[/tex] [Alternate interior angles]
[tex]m\angle OBA=m\angle BCD[/tex]
[tex]m\angle OBA=30^\circ[/tex]
In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.
We know that base angles of an isosceles triangle are congruent.
[tex]\angle OAB\cong \angle OBA[/tex] [Base angles of an isosceles triangle]
[tex]m\angle OAB=m\angle OBA[/tex]
[tex]m\angle OAB=30^\circ[/tex]
In triangle AOB,
[tex]m\angle OAB+m\angle OBA+m\angle AOB=180^\circ[/tex]
[tex]30^\circ+30^\circ+m\angle AOB=180^\circ[/tex]
[tex]60^\circ+m\angle AOB=180^\circ[/tex]
[tex]m\angle AOB=180^\circ-60^\circ[/tex]
[tex]m\angle AOB=120^\circ[/tex]
Therefore, the measure of angle AOB is 120 degrees.
Erin has two cats. The larger cat weighs 2.6 pounds more than the smaller cat. The combined weight of the two cats is 19.6 pounds. What is the weight, in pounds of the smaller cat?
Answer:
7.2
Step-by-step explanation:
just divide the total weight by 2 and add 2.6. after adding 2.6 you subtract that weight from the total.

Garnet has a container with 15 1/2 cups of flour in it. She can make one dozen muffins with 2 1/2 cups of flour. How many dozens
of muffins can Garnet make with the flour she had?
Answer:6 1/5
Step-by-step explanation:
Lets start by saying that one dozen is 12 and not a bakers dozen (13)
We will first see how many times 2 1/2 can go into 15 1/2 by dividing the two
[tex]15\frac{1}{2} /2\frac{1}{2}=6\frac{1}{5}[/tex]
then we can verify by multiplying 2 1/2 and 6 1/5
[tex]2\frac{1}{2} *6\frac{1}{5} =15\frac{1}{2}[/tex]

GIVING BRAINLY FOR WHOEVER ANSWERS THIS
Answer:
20%
Step-by-step explanation:
Probability is always expressed as a part of a whole, thereby in fractions or percentages. From the statistics gathered, it said that 80% of the time, the plane arrives right on schedule in El Centro. That means that the probability of NOT arriving on time is the other portion, which is 20%. The answer is 20%.

A ball moves in a straight line has an acceleration of a(t) = 2t + 5. Find the position function of the ball if its initial velocity is -3 cm per second and it’s initial position is 12 cm.
Answer:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
Step-by-step explanation:
Relation between acceleration, velocity and position:
The velocity function is the integral of the acceleration function.
The position function is the integral of the velocity function.
Acceleration:
As given by the problem, the acceleration function is [tex]a(t) = 2t + 5[/tex]
Velocity:
[tex]v(t) = \int a(t) dt = \int (2t+5) dt = \frac{2t^2}{2} + 5t + K = t^2 + 5t + K[/tex]
In which K is the constant of integration, which is the initial velocity. So K = -3 and:
[tex]v(t) = t^2 + 5t - 3[/tex]
Position:
[tex]s(t) = \int v(t) dt = \int (t^2 + 5t - 3) = \frac{t^3}{3} + \frac{5t^2}{2} - 3t + K[/tex]
In which K, the constant of integration, is the initial position. Since it is 12:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
2 x – 5y = –47
6 x – 5y = –71
Answer: x = - 6
y = 7
Step-by-step explanation:
Let 2x -5y = -47 be eq. 1
And 6x -5y = -71 be eq. 2
By substrate of 1 - 2:
2x-5y-6x+5y = -47+71
so -4x=24 and x= -6
Substitute x in any eq.
2(-6) - 5y = -47
-5y = -47 +12
-5y = -35 so y= 7
Write the equation of the line perpendicular to x= -3 through the point (-5,-4)

A telephone pole casts a shadow that is 12 feet long. At the same time, a man standing nearby who is 6 feet tall casts a shadow that is 2 feet 4 inches long. How tall is the
telephone pole to the nearest foot?
The telephone pole is feet tall
Answer:
31 feets
Step-by-step explanation:
Given that :
Telephone shadow Ts = 12 feets
Man's height, Mh= 6 feets
Man's shadow, Ms = 2 feets 4 inches
Height of telephone, Th =?
Recall :
1 foot = 12 inches
x foot = 4 inches
12x = 4
x = 4/12 = 1/3 inches
Hence, man's shadow = 2 1/3 feets =
Using cross multiplication :
Mh / Ms = Th / Ts
6 / 7/3 = Th / 12
6 / 2.33333 = Th / 12
12 * 6 = 2.33333 * Th
72 = 2.33333 Th
Th = 72 / 2.333333
Th = 30.85
Height of telephone pole = 31 feets
