Which angles are corresponding angles?
Check all that apply.
The corresponding angles are
2 and 6
3 and 7
5 and 3
and, 4 and 8
What are corresponding angles?
Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal are called corresponding angles.
Or, when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.
According to the given question.
We have a diagram, in which there are two parallel lines and one another line which is intersecting these two lines.
From the given diagram,
The pairs of angles 2 and 6, 1 and 5, 3 and 7, and 4 and 8 are occupying the same relative positions, upper right side, upper left side, lower left side, and lower right side respectively.
Therefore, we can say that angles
2 and 6
3 and 7
5 and 3
and, 4 and 8
are corresponding angles.

If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2
Answer:
A) 12-10
B)36+225
Step-by-step explanation:
A) 3x4=12, 5x2= 10= 12-10
B) 3x2=6x6=36, 3x5=15x15=225=36+225
For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.
What is substitution?Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.
When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.
Given, x = 3 and y = 5.
∴ 4x - 2y is,
= 4(3) - 2(5).
= 12 - 10.
= 2.
And
2x² + 3y².
= 2(3²) + 3(5²).
= 2(9) + 3(25).
= 18 + 75.
= 93.

Answer:
y=5/2x
Step-by-step explanation:
the y intercept is (0,0) so it isn't included in the equation. now we know the middle solution isn't correct. the points we use to find slope are (-2,-5) and (2,5) which ends up being 5/2.

-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False
Answer:
true
Step-by-step explanation:
If x = - 3 is a zero of the polynomial then f(- 3) = 0
f(x) = x³ + 7x² + 16x + 12
= (- 3)³ + 7(- 3)² + 16(- 3) + 12
= - 27 + 63 - 48 + 12
= 0
Since f(- 3) = 0 then x = - 3 is a zero of the polynomial

Using a graph of the function, determine which statement is NOT a true description
of this quadratic function.
Answer:
it will be 271 because u multiple
The maximum value that the function reaches is 0, which occurs at x = 6.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Since a blank grid is given, we can plot the graph of the quadratic function f(x) = x^2 - 5x - 24 using the given points:
X: 10 -8 6 4 2 4 6 8 10
f(x): -116 -12 0 -8 -20 -8 0 8 24
The graph of the quadratic function looks like a parabola opening upwards, with the vertex at the point (2, -20).
Based on the graph, we can make the following observations:
The function has a minimum value of -20, which occurs at x = 2.The function is symmetric about the vertical line that passes through the vertex (2, -20).The function intersects the x-axis at x = -3 and x = 8.The function intersects the y-axis at y = -24.Therefore, the statement that is NOT a true description of this quadratic function is:
"The function has a maximum value of 24, which occurs at x = 10."
This statement is not true because the function has a minimum value of -20 at x = 2, but it never reaches a maximum value of 24. The maximum value that the function reaches is 0, which occurs at x = 6.

Use quadrilateral ABCD. What value for m DAB would show ABCD is a parallelogram?
Answer:
m∠DAB = 101°
x = 7
y = 12
Step-by-step explanation:
Properties of a parallelogram,
1). Opposite sides of a parallelogram are equal and parallel.
2). Opposite interior angles are equal in measure.
3). Consecutive interior angles are supplementary.
By the first property,
BC ≅ AD
2x + 4 = 3x - 3
3x - 2x = 4 + 3
x = 7
AB ≅ CD
2y + 10 = 3y - 2
3y - 2y = 10 + 2
y = 12
By second property,
m∠ABC = m∠ADC
2z + 15 = 3z - 17
3z - 2z = 15 + 17
z = 32
Therefore, m∠ADC = (3z - 17)°
= 3(32) - 17
= 96 - 17
= 79°
By third property,
m∠ADC + m∠DAB = 180°
79° + m∠DAB = 180°
m∠DAB = 180° - 79°
m∠DAB = 101°

Answer:
y = -5/2x +4
Step-by-step explanation:
First, make the equation into standard form.
5x + 2y = -10
2y = -5x - 10
y = -2.5x - 5
In order for two lines to be parallel, they must have the same slope. (In y = mx + b, "m" is the slope)
The slope in y = -2.5x - 5 is -2.5, so we need to find an equation with a slope of -2.5 (or -5/2)
In y = -2/5x - 8, the slope is -2/5
In y = 2/5x + 7, the slope is 2/5
In y = 5/2x - 6, the slope is 5/2
In y = -5/2x +4, the slope is -5/2.
Thus, y = -5/2x +4 is the right answer
