Answer:
x = -21, y = 35.
Step-by-step explanation:
Use the elimination method:
x + y = 14
2x + 3y = 63
Multiply the first equation by -2:
-2x - 2y = -28
Add this to the second equation to eliminate x:
y = 35
So x + 35 = 14
x = 14 - 35
x = -21.
10x + 2=32 solve for x
Answer:
X=3
Step-by-step explanation:
10x+2= 32
10x=32-2
10x=30
X=30÷10
X= 3
Answer:
x=3
Step-by-step explanation:
10x + 2 = 32
- 2 -2 (2's cancel each other out )
10x = 30 divide each side by 10 and 10s cancel out so all your left with x =3
[tex]x = 3[/tex]
Instead of having 1.5 times as many pink flowers as white flowers, molly has decided to plant a garden with twice as many pink flowers as white flowers per row
Answer:
Row 1 = 2 white flowers
Row 2 = 3 white flowers
Row 3 = 4 white flowers
Step-by-step explanation:
Instead of having 1.5 times as many pink flowers as white flowers, Molly has decided to plant a garden with twice as many pink flowers as white flowers per row. If she plants 3 rows, with 4, 6, and 8 pink flowers, how can you find the number of white flowers in each of those rows?
Let
White flowers = x
Pink flowers = 2x
Molly plants 3 rows with 4, 6 and 8 pink flowers
Number of white flowers in each row is
Row 1
Pink flowers = 4
2x = 4
Divide both sides by 2
x= 2
White flowers = 2 in row 1
Row 2
Pink flowers = 6
2x=6
Divide both sides by 2
x= 3
White flowers in row 2 = 3
Row 3
Pink flowers = 8
2x=8
Divide both sides by 2
x= 4
White flowers in row 3 = 4
Therefore, the number of white flowers in each rows are 2, 3 and 4 respectively
Answer:
To find the number of white flowers, use the constant of proportionality and the number of pink flowers per row. If Molly plants 4, 6, and 8 pink flowers in 3 rows, she has to plant 2, 3, and 4 white flowers in those rows, so there are twice as many pink flowers as white.

Look at the graph of the linear function. The rate of change between point A and point B is 2. What is the rate of change between point C and point D? A.= negative 2 B.= negative 1/2 C.= 1/2 D.= 2
Answer:
D. 2
Step-by-step explanation:
For a linear equation, the rate of change between any given two point on the line is always constant and the same.
Therefore, since rate of change between point A and point B is said to be 2, therefore, the rate of change between point C and D would be the same as 2.
We can confirm this by using this formula to calculate the rate of change, which is: [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] C(1, 2) = (x_1, y_1) [/tex]
[tex] D(2, 4) = (x_2, y_2) [/tex]
Plug in the values into the formula:
[tex] = \frac{4 - 2}{2 - 1} = \frac{2}{1} = 2 [/tex]
As we can see, the rate of change between point C and point D is still the same as the rate of change between point A and point B = 2

D) 2

Answer:
Solution of the system will be (-3, 6).
Step-by-step explanation:
If a system of linear equations have been given in the question then we can find the solution of the linear equations by solving these equation algebraically.
But when a graph of the system of equation have been given solution of the system is the point of intersections Or common points lying on both the lines.
From the given graph,
Coordinates of the common point of both the lines is (-3, 6).
Therefore, solution of the system will be (-3, 6).

lou thinks the expression 27x^3-64 factors to (3x-4) (9x^2+12x+16). is he correct? How can you check his work? Show all work to justify your thinking.
Answer:
Step-by-step explanation:
(a³ - b³) = (a - b) (a² + ab + b²)
27x³ - 64 = 3³x³ - 4³
= (3x)³ - 4³ {a = 3x & b= 4)
Substitute in the above formula.
= (3x -4)([3x]² + 3x*4 + 4²)
= (3x - 4)(9x² + 12x + 16)
The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).

This morning, Maria's car had 16.03 gallons of fuel. Now, 2.9 gallons are left. How much fuel did Maria use?
Answer:
take 16.03 and subtract 2.9
16.03-2.9=13.13
so maria used 13.13 gallons
Step-by-step explanation:
Maria used 13.13 gallons of gas, because the 16.03 gallons she started with minus the 2.9 gallons she had left equals 13.13 gallons. You can check by adding 2.9+13.13 to equal the 16.03 she started with.

Tara is 2 years older than Ryan. The sum of their
ages is greater than 58. Describe Ryan’s age.
Ryan = 28 years
Tara = 30 years
Ryan is over 28 years old.
Step-by-step explanation:T = R + 2
T + R = 58
Replace T
(R + 2) + R = 58
2R = 56
R = 56 : 2
R = 28 years
T = 30 years

Answer:
the opposite of a negative number is positive.
Step-by-step explanation:
Negative numbers are numbers that are less than 0. The opposite of a positive number is negative, and the opposite of a negative number is positive. Since the opposite of 0 is 0 (which is neither positive nor negative), then 0 = 0.

Solve the right triangle. Side AB is 2.9, but I don't know how to find two missing angles with three sides and a 90-degree angle. Please explain your answer.
Angle A = 68 degrees
Angle B = 22 degrees
Side AB = 2.9 cm
The three values are approximate
=========================================================
Explanation:
a = BC = 2.7 and b = AC = 1.1 are the two legs of the right triangle.
Use the pythagorean theorem to find the length of the hypotenuse
a^2 + b^2 = c^2
2.7^2 + 1.1^2 = c^2
8.5 = c^2
c^2 = 8.5
c = sqrt(8.5)
c = 2.91547594742266
c = 2.9
The hypotenuse is c = AB = 2.9
--------------------
We then use trig ratios to find the two missing angles.
Let's say we ignore the hypotenuse and focus on the two legs of the triangle.
With respect to reference angle A, side BC is opposite and AC is adjacent
Use the tangent ratio to get
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 2.7/1.1
tan(A) = 2.45454545454546
A = arctan(2.45454545454546)
A = 67.8336541779176
A = 68
Note: arctan is the same as inverse tangent or [tex]\tan^{-1}[/tex]. Make sure your calculator is in degree mode.
-------------------
Similarly,
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 1.1/2.7
tan(B) = 0.4074074074074
B = arctan(0.4074074074074)
B = 22.166345822082
B = 22
Or you could use the value of A to get B = 90-A = 90-68 = 22. This works because A+B = 90 as we're working with a right triangle. In other words, A and B are complementary angles.
-------------------
In summary we found
A = 68
B = 22
AB = 2.9
