In the equation 3x+4=13, the 3 is called what?
Answer:
:Coefficient
Step-by-step explanation:
Solve the system of equations by the substitution method.
3x + 2y=22
x=5y-4
Type an ordered pair
Answer:
(6,2)
Step-by-step explanation:
To solve this equation using the substitution method we can plug in the given value of x into the equation, 3x+2y=22 and solve for y. Once we get the value of "y" then we can plug the y into our second equation which is x=5y-4.
3x+2y=22
plug in 5y-4 for the x value, so
3(5y-4)+2y=22 now distribute the 3 to the (5y-4) (multiply the 3 by 5y and -4)
3*5y= 15y and 3*-4= -12,
15y-12+2y=22 ←this is our equation after distributing
we can combine the 15y and 2y because they share the same variable
(15y+2y)
17y-12=22 add 12 to both sides to eliminate the -12 and divide by 17 to get rid of the 17 next to y or isolate the y variable
17y-12+12=22+12 → 17y=34 divide both sides by 17
[tex]\frac{17y}{17} =\frac{34}{17}[/tex] the 17's cancel and the 17 divides into 34, leaving us with
y=2
now substitute the y=2 into the equation x=5y-4
so x=5(2)-4 → x=10-4 → x=6
So we have the values for both our x and y values, all we need to do is put them in an ordered pair in the form (x,y)
so the ordered pair is (6,2)

With a tailwind , a bird flew at a ground speed of 3mi/h. Flying the same path against the same wind, the bird travels at a ground speed of 1.5mi/h. What is the bird's air speed? what is the wind speed?
The speed of a bird with respect to the wind Bird's air speed is 2.25 mi/h. The speed of the wind with respect to the ground wind's speed is 0.75 mi/h.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Relative speed is usually given in terms of the speed of body A with respect to another body B (Vab)
Vab = Va - Vb
Vab = Speed of A relative to B
Va = Speed of A
Vb = Speed of B
So, for this question, when the bird is travelling in the same direction of the wind, the speed of the bird with respect to the ground is 3 mi/h
(Speed of bird with respect to the wind)
= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)
Speed of bird with respect to the wind = x
Speed of bird with respect to ground = 3 mi/h
Speed of the wind with respect to the ground = y
(Speed of bird with respect to the wind)
= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)
x = 3 - y
When the bird is travelling in the opposite direction, the speed of the bird with respect to the ground is 1.5 mi/h
Speed of bird with respect to the wind = x
Speed of bird with respect to ground = 1.5 mi/h
Speed of the wind with respect to the ground = -y (Negative since the wind is in the opposite direction)
(Speed of bird with respect to the wind)
= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)
x = 1.5 - (-y)
x = 1.5 + y
We can then solve this system of equations
x = 3 - y
x = 1.5 + y
1.5 + y = 3 - y
y + y = 3 - 1.5
2y = 1.5
Divide both sides by 2
(2y/2) = (1.5/2)
y = 0.75 mi/h
x = 1.5 + y
x = 1.5 + 0.75
x = 2.25 mi/h

What is the value of x? −7.5(x−3)=3.75
[tex]{\boxed{ \Huge{ \blue{ \mathcal{{ Answer}}}}}}[/tex]
⇛-7.5(x−3) = 3.75
⇛-7.5x + 22.5 = 3.75
⇛-7.5x = 3.75 - 22.5
⇛-7.5x = -18.75
⇛x = -18.75 ÷ -7.5
⇛x = -18.75/-7.5
⇛x = 2.5
Answer:
2.5
Step-by-step explanation:
-7.5(x-3)=3.75
or, -7.5x+22.5=3.75
or, -7.5x= 3.75-22.5
or, -7.5x= -18.75
or, x= 18.75÷7.5
or, x= 2.5

A regular heptagon has sides measuring 3.2 inches and an apothem that measures 2.9 inches. What is the area of this heptagon?
Answer:
32.48 square inches
Step-by-step explanation:
The area of a polygon is [tex]A=\frac{nsa}{2}[/tex] where [tex]n[/tex] is the number of sides of the polygon, [tex]s[/tex] is the side length of the polygon, and [tex]a[/tex] is the length of the apothem.
We are given the polygon is a heptagon, so it has 7 sides, making [tex]n=7[/tex]
We are given the heptagon's side length is 3.2 inches, making [tex]s=3.2[/tex]
We are also given an apothem of 2.9 inches, making [tex]a=2.9[/tex]
Therefore, by using the formula for the area of a polygon, we get[tex]A=\frac{nsa}{2}=\frac{7*3.2*2.9}{2}=\frac{64.96}{2}=32.48[/tex]
In conclusion, the area of the heptagon is 32.48 square inches

Answer: I think it’s D
Step-by-step explanation:
Answer:
The domain is a set/group of x-values. The range is a set/group of y-values. The first option is not true because there are x-values which are greater than 0 (right side of graph). The second option is not true because the set of y-value stops before it hits the y=0. The third option is not true because there are no y-values which are less than 0 (bottom of graph). The fourth option is correct because the x-values stretch from -infinity on the left side of the graph to positive infinity of the right side of the graph.
