Y=-6x+10. Y=-6x+3
Solve the system of equations
Given:
The system of equations is
[tex]y=-6x+10[/tex]
[tex]y=-6x+3[/tex]
To find:
The solution of given system of equations.
Solution:
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
For [tex]y=-6x+10[/tex], slope is -6 and y-intercept is 10.
For [tex]y=-6x+3[/tex], slope is -6 and y-intercept is 3.
Slopes of both lines are but the y-intercepts are difference. So, the two lines are parallel.
Therefore, the given system of equation has no solution.
There are 4 sharks and 5 dolphins. Write the ratio of dolphins to animals.
Answer:
5:9
Step-by-step explanation:
Number of sharks = 4
Number of dolphins = 5
Number of animals = number of sharks + number of dolphins
Number of animals = 4 + 5 = 9
Therefore, the ratio of dolphins to animals = 5:9

39. 7 + 0 = 7 and 7 x 0 = 0
A rectangular lot is 20 yards longer than it is wide and its area is 2400 square yards. Find the dimensions of the lot
Answer:
120
Step-by-step explanation:
Divide 2400 by 20 to get your answer! It may be wrong
Answer:
W = 40
L = 60
Step-by-step explanation:
L = 20 + W
L*W = 2400
(20 + W)*W = 2400
W^2 + 20*W - 2400 = 0
(W + 60)*(W - 40) = 0
W = 40 (yards)
L = 20 + W
= 20 + 40 = 60
W = 40

Divide each side by -7, remembering to flip the inequality
-7x/-7 > -21/-7
x > 3
Answer:
x > 3
Step-by-step explanation:
Get the variable (x) by itself. Divide both sides by -7. Since a negative/ negative = positive, the 3 is positive. When you multiply or divide by a negative, the inequality sign flips. I hope this helped.

How many solutions would this system of equations have?
y = 2x + 1
y =2(x+3)
a) One
b) No solutions
c) Two solution
d) Infinitely Many solutions.
Answer:
b) No solutions
Step-by-step explanation:
y=2x+1
y= 2(x+3)
Substitute the y in y=2x+1 with 2(x+3)
2(x+3)=2x+1
Then distribute the 2.
2x+6=2x+1
Subtract 2x from both sides to isolate the variable.
6=1
this statement is false, meaning the system of equations has no solutions.
jose flies a kite 17 1/2 ft above the ground. he increases its elevation by 4 3/4 ft by letting out some string. then he reels in the string and changes its elevation by -15.8 ft. after jose reels in the string, what is the kite's elevation relative to the ground? show your work
Answer:
6.45 feet
Step-by-step explanation:
He starts 17 and 1/2 feet off the ground
Elevation relative to ground: 17 1/2
Then he increases the height by 4 and 3/4
Expression: 17 1/2 +4 3/4
Elevation relative to ground: 22 1/4
Next he decreases the elevation by 15.8 feet
Expression: 22.25-15.8
Elevation relative to ground: 6.45
The answer 6.45 feet from the ground

here is a list of ingredients for making 12 rock cakes nihay wants to make 42 cakes does she have enough sugar to make 42rock cakes u must show your working
Step-by-step explanation:
So we know that for 12 rock cakes we need 225g flour and 75g sugar to get 42 rock cakes we need to multiply the number of ingredients by 3.5 (42/12 =3.5)
This gets us 787.5 g flour and 262.5 g sugar.
Show work:
[tex]42 \div 12 = 3.5[/tex]
[tex]225 \times 3.5 = 787.5[/tex]
[tex]75 \times 3.5 = 262.5 [/tex]
[tex]787.5 < 800[/tex]
[tex]262.5 < 300[/tex]
Nishat has enough flour and sugar to make 42 rock cakes.

Step-by-step explanation:
For which values of A, B, and C will AX +BY=C be a vertical line through the point (8,6)
A. A=1, B=0, C=6
B. A=1, B=0, C=8
C. A=0, B=1, C=6
D. A=0, B=1, C=8
Answer:
B. A = 1, B = 0, C = 8
Step-by-step explanation:
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (8, 6) with x- coordinate 8, thus
x = 8 is the equation of the vertical line
In comparison to
Ax + By = C, then
A = 1, B = 0, C = 8, that is
x + 0 = 8
x = 8 being the required equation
A projectile is thrown upward so that it's distance above the ground after t seconds is h=-16t^2+480t. After how many seconds does it reach its maximum height?
Answer:
t = 15 s
Step-by-step explanation:
A projectile is thrown upward so that it's distance above the ground after t seconds is as follows :
[tex]h=-16t^2+480t[/tex] ...(1)
We need to find after how many seconds does it reach its maximum height. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
[tex]\dfrac{d(-16t^2+480t)}{dt}=0\\\\-32t+480=0\\\\t=\dfrac{480}{32}\\\\t=15\ s[/tex]
So, it will reach its maximum height in 15 seconds.
What is the equation of a line that passes through the points (3, 6) and (8, 4)?
Answer:
2x + 5y = 36 in standard form
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~
(3, 6)
(8, 4)
m = [tex]-\frac{2}{5}[/tex]
y - 6 = [tex]-\frac{2}{5}[/tex] ( x - 3 )
y = [tex]-\frac{2}{5}[/tex] x + [tex]\frac{36}{5}[/tex] in slope-intercept form
2x + 5y = 36 in standard form

A family ordered two pizzas for dinner. They ate 1/2 of the first pizza and
1/4 of the second pizza. How much more of the first pizza did they eat?
A)1/2
B)1/4
C)1/8
D)3/4
Answer:
they ate 3/4 part of pizza
Step-by-step explanation:
=1/2+1/4
=1×2/2×2 + 1/4
=2/4+1/4
=3/4
Answer:
B) 1/4 because if the pizzas have 8 slices then 1/4=2 slices and 1/2=4 slices 4-2=2 and 2 slices equal 1/4 of the pizza.
