Answer:
80
Step-by-step explanation:
consider the following equations: -x-y=1 y=x+3 if the two equations are graphed, at what point do the lines representing the two equations intersect? (-1,2) (-2,1) (1,-2) (2,-1)
Answer:
(-2, 1)
Step-by-step explanation:
consider the following equations: -x-y=1 y=x+3
For the lines to intersect, the values must be the same
-x-y=1
x + y = -1
y = -x - 1
Equating the y values
-x - 1 = x+ 3
-x-x = 3 + 1
-2x = 4
x = 4/-2
x = -2
Substitute x = -2 into y = x+3
y = -2 + 3
y = 1
Hence the required coordinate is (-2, 1)

Find the area of the parallelogram, 22mm 11mm. Please help im stu-pid
Please help with 1234, due tonight would mean everything! Will give brainly!!
Answer: For 1, the answer is B since there is no rational number for sqrt17.
For 2, the answer is C since it has to be less than 11 whose square is 121 and larger than 10 whose squre is 100.
For 3 the answer is B. Just plug the x value into the equation. => y=1/2(-1)-2 => y= -1/2-2 => -2 1/2.
For 4 the answer is A because the graph first goes up then stys their staticly for a while then plumets down. It fits the description of the first one.

Ok my question says "destiny and carla had a total of 3 gallons of paint to share for a project they had 1 gallon each yellow blue and red paint destiny used 3/8 gallon of yellow paint 1/2 of blue paint 1/4 of red paint carla used 1/4 of yellow 3/8 of blue and 1/4 of red then part a ask how much more paint in gallons did destiny use than carly
Answer: 1/4
Step-by-step explanation:
Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:
= ⅜ + ½ + ¼
= 3/8 + 4/8 + 2/8
= 9/8
= 1 1/8
Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:
= 1/4 + 3/8 + 1/4
= 2/8 + 3/8 + 2/8
= 7/8
The numybe of paint that Destiny use more than Carla will be:
= 1 1/8 - 7/8
= 2/8
= 1/4
Destiny used 1/4 paint more than Carla
Mary simplified the math expression below. The steps that she took are shown. Which is the line where Mary first made her mistake. Line A: – 6 + 9 Line B: [8 + 5 x 3] – 6 + 9 Line C: – 6 + 9 Line D: 23 – 6 + 9 Line E: 23 – 15 Line F: 8
Answer:
Line E
Step-by-step explanation:
Given
The instructions in the question
Required
The first line of mistake
The question has missing details, as the original expression is not given;
Reading through the question, one can observe that, Mary made a mistake at Line E.
The expression on D is:
[tex]23 - 6 + 9[/tex]
The expression on E is:
[tex]23 - 15[/tex]
The actual result of D is:
[tex]23 - 6 + 9 = 23 + 3[/tex]
not
[tex]23 - 15[/tex]
Because:
[tex]-6 + 9 = 3[/tex]
[tex]-6 + 9 \ne 15[/tex]
With the available information, we can conclude that Mary's first mistake is at line E

Answer:
-3x³y∛9
Step-by-step explanation:
The expression can be simplified by removing perfect cubes from under the radical.
[tex]\sqrt[3]{-243x^9y^3}=\sqrt[3]{(-3x^3y)^3\cdot9}=\boxed{-3x^3y\sqrt[3]{9}}[/tex]

It helps to realize that 243 = 3^5 = (3^3)(3^2).
One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60
Answer:
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
From the above question, one of the angles = 60°
The value for the two other interior angles = 180° - 60° = 120°
Hence, the following options could be the values of x and y is given as x + y = 120
Therefore,
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
If you horizontally stretch the quadratic parent function, f(x) = X^2 by a factor
of 5, what is the equation of the new function?
9514 1404 393
Answer:
g(x) = x^2/25
Step-by-step explanation:
For a horizontal stretch by a factor of k, x is replaced by x/k.
g(x) = f(x/5) = (x/5)^2 = x^2/25
The new function is ...
g(x) = x^2/25
