Answer:
( -1/2, -2 1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
( -2+1)/2 = -1/2
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
( -1+-4)/2 = -5/2 = -2 1/2
( -1/2, -2 1/2)
Write the sum of -5x - 7y + 6 and -4 + 3x in standard form.
Answer:
Step-by-step explanation:
first, you need to know what standard form is
Ax + By = C
which is basically
number(x) + number(y) = number
to put it simply..
so now we can evaluate the expression (the random mess they gave us)
-5x - 7y + 6 and -4 + 3x
we need to put em together so just toss an equal sign between em
so now we have
-5x - 7y + 6 = -4 + 3x
no combine like terms
-8x - 7y + 6 = -4
-8x - 7y = -10
and thats the answer in standard form
Write the standard form of the equation of a circle with radius 10 and center (9,3)
Answer:
[tex](x-9)^{2}+(y-3)^{2} =100[/tex]
Step-by-step explanation:
The standard form formula for a circle equation is [tex](x-h)^{2}+(y-k)^{2} =r^{2}[/tex], where (h,k) represents the center of the circle, and r represents the radius.
r=10
(h,k)= (9,3)
[tex](x-h)^{2}+(y-k)^{2} =r^{2}[/tex]
[tex](x-9)^{2}+(y-3)^{2} =10^{2}\\(x-9)^{2}+(y-3)^{2} =100[/tex]

Convert 1.5 days to seconds.
A. 36 seconds
B. 12,960 seconds
C. 129,600 seconds
D. 2,160 seconds
Please I need help
Answer:
C.129,600
Step-by-step explanation:
1 day = 24 hour
1.5 days = ?
(1.5days × 24 hour)/1day
=36hours
1hour = 3600 second
36hour = ?
(36hours × 3600second)/1hour
= 129,600

Step-by-step explanation:
A line with a slope of 3/4 passes through (-2,-3). Write the equation of the line in general form.
Step-by-step explanation:
Disclaimer: By general form, I will assume that the problem would like us to write the answer in Slope-Intercept Form.
We know that slope-intercept form is y=mx+b. m = the slope, and b = the point where the line hits the y-axis on the graph (the y-intercept).
The slope is given (3/4), which we can plug into our equation. Now we have y=3/4x + b.
Now we can see that the line passes through (-2,-3). Let's plug in those coordinates into our equation. Remember! All coordinates are written in (x,y), meaning that x = -2 and y = -3. "B" is the missing variable that we need to solve for. Time to substitute!
-3 = (3/4 x -3) + b
-3 = -9/4 + b
b=-3/4.
Now that we know B, let's rewrite our equation and get our answer!
y = 3/4x - 3/4
Write an equation for a polynomial with all the following features a. The degree is 5 b. The polynomial has 4 terms c. The graph of the polynomial crosses the vertical axis at y=12
Answer:
f(x) = ax^5 + bx^3 + cx^2 + 12.
Step-by-step explanation:
the degree is 5 so we will have a term like:
ax^5
it crosses the vertical axis at y = 12 so we will have a constant term equal to 12
the polynomial has 4 terms, and we already have two so we can make up two more but the exponent must be between 1 and 4
f(x) = ax^5 + bx^3 + cx^2 + 12.
it has 4 terms, f(0) = 12, then it intersects the y-axis at y = 12, and the maximum exponent is 5, then the degree of f(x) is 5

Answer:
x = 17.5
Step-by-step explanation:
5/8 = x/28
=> 5(28) = 8x
=> 140 = 8x
=> 8x = 140
=> x = 140/8
=> x = 70/4
=> x = 35/2
=> x = 17.5
Answer:
x=17.5Step-by-step explanation:
first, we need to do

does anyone know how to solve this
Answer:
see explanation
Step-by-step explanation:
let t be the cost of 1 t- shirt and s be the cost of 1 pair of shoes , then
4t + 3s = 325 → (1)
2t + 2s = 194 → (2)
(b) Solving by elimination
Multiplying (2) by - 2 and adding to (1) will eliminate t
- 4t - 4s = - 388 → (3)
Add (1) and (3) term by term to eliminate t
0 - s = - 63
- s = - 63 ( multiply both sides by - 1 )
s = 63
Substitute s = 63 into either of the 2 equations and solve for t
Substituting into (2)
2t + 2(63) = 194
2t + 126 = 194 ( subtract 126 from both sides )
2t = 68 ( divide both sides by 2 )
t = 34
Cost of pair of shoes = AED 63 and cost of t- shirt = AED 34
if the 9 in 29.564 was changed to a 2 how much would the value change? help pls I'm trying to finish it in under 1 min
Answer:
7
Step-by-step explanation:
Answer:
well all you got to do is round to the nearest tenths
so 29.564 the 5 would make the 9 be 30.564 but with the the new equation would be 22.564 which would be rounded to 23.564

f(x)=(x^5+5)^1/3, find f^-1 (x)
Answer:
5√(x^1/3-5)
Step-by-step explanation:
hey!
f(x)=(x^5 +5)^1/3
let f(x) be y
y=(x^5 +5)^1/3
now, interchanging x and y
or, x=(y^5 +5)^1/3
or, ∛x= y^5 + 5
or, x^1/3-5=y^5
or, y=5√(x^1/3-5)
therefore f^-1=5√(x^1/3-5)
hope it helps!

which two expressions are equivalent.
Answer:
C and D
Step-by-step explanation:
It is the same but its reversed in the parentheses, so they are equivalent.
Answer: C and D
Step-by-step explanation: SO what you need to do here is pick any number to plug in as y let’s say 2. 7+(5*2)=17 and then you solve for the next equation using 2. (7+5)*2=24. Now we know its not a. Let’s do b (12-4)*2=16 and 12-(4*2)=4 that can’t be it. Now c 8+(2*3)=14 and 8+(3*2)=14. Now D (11/2)+6=11.5 and 6+(2/11)= 11.5. You can use any number to plug in.

Find the value of y so that the line that passes through the points (5,4) and (-5, y) has a slope of
3/5
Answer:
y = -2
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
3/5 = (y - 4)/(-5 - 5)
3/5 = (y - 4)/-10
y - 4 = -10(3/5)
y - 4 = -6
y = -2
Which expression is equivalent to 7a - 8 - 2a + 4?
Answer:
a = 4/5 OR 5a - 4
Step-by-step explanation:
If you set it equivalent to 0:
7a - 8 - 2a + 4 = 0
5a - 4 = 0
5a = 4
a = 4/5
If you are only simplifying:
7a - 8 - 2a + 4
5a - 4

Answer:
10, 4, 8
Step-by-step explanation:
Let's start with 6...
We need to plug in 6 for y
y=x-4
6=x-4
x=10
Now we plug in 0 for y
y=x-4
0=x-4
x=4
Now we plug in 4 for y
4=x-4
x=8
