Answer:
Option A
Step-by-step explanation:
System of the equations has been given as,
5x + 3y = -6 -------(1)
2x + y = -4 ------(2)
Equation (2) multiplied by 3 then subtracted from equation (1),
(5x + 3y) - 3(2x + y) = -6 - 3(-4)
5x + 3y - 6x - 3y = -6 + 12
-x = 6
x = -6
From equation (2),
2(-6) + y = -4
y = 12 - 4
y = 8
Therefore, (-6, 8) is the only solution of the given system of equations.
Option A will be the answer.

What is the equation of the line that passes through the point (3,-5) and has a
slope of 2/3?
Answer:
y=2/3x-7
Step-by-step explanation:
y-y1=m(x-x1)
y-(-5)=2/3(x-3)
y+5=2/3x-2
y=2/3x-2-5
y=2/3x-7

Calculate the slope of the line passing through points (-3, 4) and (-3,-7)
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 4 ) and (x₂, y₂ ) = (- 3, - 7 )
m = [tex]\frac{-7-4}{-3+3}[/tex] = [tex]\frac{-11}{0}[/tex]
Since division by zero is undefined then the slope is undefined
This indicates the line is vertical and parallel to the y- axis

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :
5t 5t • 2
5t = —— = ——————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
10t-7
————— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
10t-7 = 0
Solving a Single Variable Equation:
3.2 Solve : 10t-7 = 0
Add 7 to both sides of the equation :
10t = 7
Divide both sides of the equation by 10:
t = 7/10 = 0.700
One solution was found :
t = 7/10 = 0.700

What are the Type of angles?We have the following types of angles as
Zero angleAcute AngleObtuse angleRight AngleStraight angleReflex angleComplete angleAngles can be categorized according to their degree angle magnitude:
Zero degreeWhen both angle arms are at the same place, a zero angle is created. Rays emanating from the same spot at an angle of zero.
Acute angleThe measurement of an angle that is larger than 0 but less than 90 is called an acute angle.
Right angleThe angle that measures accurately 90 is the right angle.
Obtuse angleThe definition of an obtuse angle is an angle that is larger than 90 but less than 0.
Straight AngleThe exact measurement of an angle 180 is a straight angle.
Reflex angleThe measurement of an angle that is greater than 180 but less than 360 is called a reflex angle.
Complete angleThe exact measurement of an angle is 360 its complete angle.
So, 90 is Right Angle
60 is Acute Angle
70 is Acute angle
80 is Acute angle
30 is Acute Angle
20 is Acute Angle
110 is Obtuse Angle
100 is Obtuse Angle

Answer:
(3×7)+(1.5×5)

28.5cm^2
Answer:
= 28.5cm²
Step-by-step explanation:
A is a full diamond which is equal to 3cm²
B has: 7 full diamonds and five 1/2 diamonds
Five 1/2 diamonds = 2 full diamonds and 1/2 a diamond.
If 1 diamond(A) = 3cm²
What about 9 diamonds = ?
= (9 × 3) ÷1
= 27cm²
If 1 diamond(A) = 3cm²
What about 1/2 a diamond = ?
= 1/2 × 3
= 1.5cm²
Total = 27 + 1.5
= 28.5cm²

Answer:
75 degrees
Step-by-step explanation:
3x+15 = 4x - 5
-3x -3x
15=x-5
+5 +5
x=20
4(20)-5 = 75
Answer:
75
Step-by-step explanation:
1 and 2 are corresponding angles meaning that they are equal to each other or congruent
so we set up an equation
4x-5=3x+15 and since for x
step 1 subtract each side by 3x
4x-3x=x
now we have
x-5=15
step 2 add 5 to each side
5+15=20
x=20
now we just plug in 20 to 4x - 5
4x20=80
80-5=75
therefore your answer is 75
