Answer:
x = 2 and y = 1
Step-by-step explanation:
Given equations are :
2x-y=3 ...(1)
3x+y=7 ...(2)
Add equation (1) and (2) as follows :
2x-y + 3x+y = 3 + 7
2x + 3x = 10
5x = 10
x = 2
Put the value of x in equation (1)
2(2)-y=3
4-y = 3
y = 4-3
y = 1
Hence, the solution of the given equations are (2,1).

Write an equation of a line that passes through the point (-2,3) and is perpendicular to
the line x = 4
Answer:
y = 3
Step-by-step explanation:
x = 4 has an undefined slope meaning on a graph the line is vertical. In order to form a line perpendicular to this, we need a line with zero slope (horizontal line). We need to look strictly at the y coordinate to help determine the equation. In this case, we have a y coordinate of 3. Therefore, the equation will be y = 3.
If x and y vary directly, and x 60 when
y= 5, what is the value of y when x =36?
Answer:

the girl boy ratio was 9-7 if 63 girls attended how many boys attended?
Answer:
49 100 percnet
Step-by-step explanation:
9:7
times by 7
The number of boys attended are 49.
What is the definition of the ratio?In mathematics, a ratio is a term used to compare two numbers. It is used to express how large or small an amount is in comparison to another. A ratio compares two quantities by dividing them. The dividend is referred to as the 'antecedent,' while the divisor is referred to as the 'consequent.'For the given question.
Let the number of girls be 'x' = 63.
Let the number of boys be 'y'.
The ratio of girls to boy is 9:7.
Thus,
x/y = 9/7
Boys = ?
y = 7x/9
Put x = 63
y = 7×63/9
y = 49
Thus, the number of boys attended are 49.

The diagram below shows parallelogram ABCD with diagonals AC and BD intersecting at E
What additional Information is sufficient to prove that parallelogram ABCD is also a rhombus?
9514 1404 393
Answer:
D. AC ⊥ BD
Step-by-step explanation:
Given that ABCD is a parallelogram, we already know A (BD bisects AC) and B (AB ║ CD). Statement C (AC ≅ BD) will not be true for a parallelogram or rhombus.
Statement D (AC ⊥ BD) guarantees the parallelogram is a rhombus.

use the quotient rule to find the derrivatives of 3/x^2
Answer:
f'(x) = -6/x³
Step-by-step explanation:
We are given;
f(x) = 3/x²
Using quotient rule, we can write as;
f(x) = g(x)/h(x)
To find the derivative, from quotient rule, we can write;
f'(x) = [(h(x)*g'(x)) - (g(x)*h'(x))]/(h(x))²
g'(x) = 0
h'(x) = 2x
Thus;
f'(x) = [(x²*0) - (3*2x)]/(x²)²
f'(x) = -6x/x⁴ = -6/x³
f'(x) = -6/x³
