A taxi charges a flat rate of $8 plus $2 per mile travelled. Write an equation to represent the total cost of a journey. (Let d miles = distance travelled)
Answer:
Y = 8 + 2d
Step-by-step explanation:
Y = 8 + 2d where d is miles traveled
Answer:
y = 2d + 8
Brainliest, please!
Step-by-step explanation:
y = mx + b
m = slope, b = y-intercept
The flat rate of $8 is the y-intercept, and the slope is $2.
y = 2x + 8
We can change x to d to match the context of this problem.
y = 2d + 8
The point A,B,C and D represent the complex number Z1,Z2,Z3 and Z4 and O is the origin. If OABC is a parallelogram, and Z1=1+3i and Z2=4+5i, find Z3
Complex numbers are divided into two parts; real and imaginary parts. The value of Z3 is [tex]5+ 8i[/tex]
Given that:
[tex]Z_1 = 1 + 3i[/tex]
[tex]Z_2 = 4 + 5i[/tex]
Since O is the origin, then:
[tex]C = OA + OB[/tex]
This means that:
[tex]Z_3 = Z_1 + Z_2[/tex]
So, we have:
[tex]Z_3 = 1 + 3i + 4 + 5i[/tex]
Collect like terms
[tex]Z_3 = 1 + 4+ 3i + 5i[/tex]
[tex]Z_3 = 5+ 8i[/tex]
Hence, complex number Z3 is [tex]5+ 8i[/tex]

What's the angle sum of a polygon having 7 sides.
Answer:
900°
Step-by-step explanation:
The sum of the interior angles of a polygon is

4b + 5 = 1 + 5b
what is b?
Answer: b = 4
Step-by-step explanation:
Given
4b + 5 = 1 + 5b
Subtract 4b on both sides
4b + 5 - 4b = 1 + 5b - 4b
5 = 1 + b
Subtract 1 on both sides
5 - 1 = 1 + b - 1

3) {(1,2), (3,4),(4,5),(5,6)} 4) {(0,0),(1, 1), (2, 2), (3, 3)}
Answer:
Set 1 is not a function
Step-by-step explanation:
You can have the same y value multiple times in a function, but you cannot have repeating x values. In set 1, there are two x values that are the same (3,2) and (3,1), so it is not a function.

Answer:
Theta = 37.9 degrees
AC = 11.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp/ adj
tan theta = 7/9
tan ^ -1 tan theta = tan ^-1 (7/9)
theta =37.87498
To 1 decimal place
Theta = 37.9 degrees
We use the Pythagorean theorem to find AC
a^2 + b^2 = c^2
7^2 + 9^2 = AC^2
49+81 = AC^2
130 = AC^2
Taking the square root of each side
sqrt(130) = sqrt(AC^2)
AC = 11.40175
Rounding to 1 decimal place
AC = 11.4

If x+y=3 and xy=2 find the value of x^2+y^2
Answer:
yes but something like that
Answer:
5
Step-by-step explanation:
We know that
[tex]x + y = 3[/tex]
and
[tex]xy = 2[/tex]
Solve for x in first variable
[tex]x = 3 - y[/tex]
Substitute this into second equation
[tex](3 - y)y = 2[/tex]
[tex] - {y}^{2} + 3y - 2[/tex]
Simplify
[tex] {y}^{2} - 3y + 2[/tex]
[tex](y - 1)(y - 2)[/tex]
[tex]y = 1[/tex]
[tex]y = 2[/tex]
So x or y can be
[tex]x = 1 \: \: y = 2[/tex]
or
[tex]x = 2 \: \: \: y = 1[/tex]
So we need to find x^2 and y^2.

A girl who normally gets A's didn't do the first assignment given on the first day of school and now has 0%. How many 95% grades will she need to achieve an average of 90% overall? The points for each assignment are based on what she scores.
Answer:
19 of 95% grades
Step-by-step explanation:
90= (0+95(x-1))/x
90x=0+95(x-1)
90x=95(x-1)
90x=95x-95
90x-95x=-95
-5x=-95
x=-95/-5

3x - 2y = 16 and x - 2y = 4 (any method <3)
Answer: (x, y) = (6, 1)
This means x = 6 and y = 1
==========================================================
Explanation:
I'll use the substitution method to solve this system.
Let's solve the second equation for x
x-2y = 4
x = 4+2y
Then plug that into the first equation so we can solve for y.
3x - 2y = 16
3(4+2y) - 2y = 16 ... x replaced with 4+2y
12+6y - 2y = 16
12 + 4y = 16
4y = 16-12
4y = 4
y = 4/4
y = 1
Lastly, use this y value to find x
x = 4 + 2y
x = 4 + 2(1)
x = 6
The solution as an ordered pair is (x, y) = (6, 1)
---------------------------------
Checking the answer:
Plug those x,y coordinates into the first equation
3x - 2y = 16
3(6) - 2(1) = 16
18 - 2 = 16
16 = 16
That confirms the first equation. Repeat for the second equation
x - 2y = 4
6 - 2(1) = 4
6 - 2 = 4
4 = 4
Both equations are confirmed.

When a projector is placed 10 meters from a screen as shown, it produces an image 3 meters high. If the tallest image that the projector can produce without distortion is 4.5 meters high, what's the maximum distance the projector can be placed form the screen
Answer:
Step-by-step explanation: 10 meters/3 meters =x/4.5 meters
Where x = the maximum distance the projector can be placed that can produce an image 4.5 meters high
3x = 10 (4.5)
3x = 45
X= 45/3
X= 15 meters
So, the maximum distance that the projector can be placed from the screen which produces an image 4.5 meters high is 15 meters.
