Solve the system of equations.
2x+8y=6
-5x-20y+-15
Answer:
2x+8y=6
Step 1: Add -8y to both sides.
2x+8y+−8y=6+−8y
2x=−8y+6
Step 2: Divide both sides by 2
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-8y+6}{2}[/tex]
x=−4y+3
_________________________________________________________
−5x−20y−15
There are no like terms.
Answer:
=−5x−20y−15

(x – 4)2 = -9 has no real solution
Answer:
x = -1/2
Step-by-step explanation:
(x - 4) * 2 = -9
Divide both sides by 2:
x - 4 = - 9 / 2
Add 4 to both sides:
x = - 1 / 2.
Answer:
Actually, it does have a solution

diagram of ABCD to find m
Answer:
since the pairs of opposite lines in the diagram are parallel the measurement of B is also 63
to fine A and C simply subtract 180 - 63 which gives us 117 so
A = 117
B = 63
C = 117
D = 63

Answer: 6, -1
Step-by-step explanation:
1. Look at both of the lines. (Blue and purple)
2. Which dot connects to both lines? (The dot which is green)
3. Since they’re together, that’s the answer.
4. Find the coordinates.
5. Go to “0” and go left until you hit the green dot area. (6 as X axis)
6. Go down to the green dot to find the Y coordinate. (-1 as Y axis)
7. You got the answer (6, -1) !
What is the y-intercept when a line has a slope of 3 and passes through
the point (2, 7)?
Answer:
The y-intercept is (0,1)
Step-by-step explanation:
So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).
Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.
y-7=3(0-2)
y-7=3(-2)
y-7= -6.
-6+7= 1, so y=1
The ordered pair is then (0,1). Hope this was useful :)
Line t has slope 3 and passes through (0, 0). Follow these steps:
Step 1: Start at (0, 0)
Step 2: Move right 8 units

Write an equation in point-slope form of the line that passes through the point (5,-12) and has a slope of m= -2/5
I hope that it will be help full for u
Step-by-step explanation:As we know point slope form ,
(Y- Y1) = m (X- X1)
As given data ,
m = -2/5
(X1,Y1) = (5, -12)
X1= 5 , Y1= -12
putt in the above equation these values, we get
Y-(-12) = (-2/5) ( X-5)
Y+12=(-2/5)X+2
Y= (-2/5)X -10 Ans ,ITs also an answer but if you want to simplify more ,taking LCM we get
Y = ((-2)X-50)/5
5Y=(-2)X-50 Ans7=x+12

Lizzy has 6.5 hours to tutor 4 students and spend 1.5 hours in a lab. She plans to
tutor each student the same amount of time. The inequality 4t +1.5 < 6.5 can be
used to find t, the greatest amount of time in hours Lizzy could spend with each
student. a. Solve the inequality and interpret what your solution means. b. Can
Lizzy tutor each student for 1.5 hours? Explain. *
Answer:
A. t= 4.1
B. No because t = 4.1 and if you do 6.5 divided by 1.5 then you get 4.3 and that won't work.

Answer:
measure of angle p=
94
Step-by-step explanation:
ok 5 sided polygon= 540
so put all of those equal to 540
need to find x first
540=132+(4x-10)+(5x-11)+128+(4x+2)
simplify and combine like terms
x=23
now plug in for angle p
(4(23)+2)
94

2, Jasper withdrew $45.00 from her savings account. She then used her debit card to buy groceries for $30.15, and then deposited a check for $14.65. What was the total amount of change in Jasper’s account?
1. Answer/Step-by-step explanation:
Diving question: 0 - 35.25 + -8.5 = -43.75 below sea level
Baking question: insolvable by lack of information.
2. Answer/Step-by-step explanation:
A money decrease of $60.50 (or -60.50 increase and change)
? - 45 - 30.15 + 14.65 = -60.50
Since we are finding the change it is best to replace the question mark with 0 so that it is easier to solve.
0 - 45 = -45
-45 - 30.15 = -75.25
-75.25 + 14.65 = -60.50

Write your answer in simplest radical form.
units
Answer:
c = 3[tex]\sqrt{6}[/tex]
Step-by-step explanation:
triangle is right isosceles so both sides equal 3[tex]\sqrt{3}[/tex]
can use pythagorean theorem which is square each leg and set it equal to the hypotenuse (side 'c') squared
(3[tex]\sqrt{3}[/tex])^2 + (3[tex]\sqrt{3}[/tex])^2 = c^2
(9x3) + (9x3) = c^2
27 + 27 = c^2
54 = c^2
c = [tex]\sqrt{54}[/tex]
simplify [tex]\sqrt{54}[/tex] to equal = [tex]\sqrt{9}[/tex] x [tex]\sqrt{6}[/tex] which simplies to 3[tex]\sqrt{6}[/tex]
