It goes through that one on the graph
What is the slope of this ?
Answer:
Essentially, slope is rise/run. Rise is how many units up the graph, and run is how far to the left or right it goes. Rise will be negative if it's going down, and run will be negative if it's going left. There's two ways to find the slope in this case.
1. Stick to the more visual aspect of it, and count how many units up from one point to the next point. Point (1,2) is 2 units up from point (0,0). Then you count how many units right or left it goes. In this case, it's 1 towards the right. This means the rise/run comes out to be 2/1, which means the slope=2.
2. Look at the equations. y=mx+b is the linear format for these lines. y is the y coordinate, m is the slope, x is the x coordinate, and b is the y intercept (the point where x=0). These two lines have shared slope values, which means the slope for both of them is 2.

If triangle ABC is congruent to XYZ, which statement is always true
Answer:
B.
Step-by-step explanation:
BC and YZ are the two angles at the end of both equations, and will always line up in the triangle.
(hope this helps!)
Given that triangle ABC is congruent to triangle XYZ, the statement from the given options that is always true is:
B. [tex]\mathbf{\overline{BC} \cong \overline{YZ}}[/tex]
Recall:
Congruent triangles have all pairs of corresponding angles and side equal.Thus, given that triangle ABC and triangle XYZ are congruent to each other, it means that:
<A is congruent to <X
<B is congruent to <Y
<C is congruent to <Z
AB is congruent to XY
BC is congruent to YZ
AC is congruent to XZ
Therefore, given that triangle ABC is congruent to triangle XYZ, the statement from the given options that is always true is:

Veronica went to the local convenience store to buy bread, milk, dishwashing liquid, and paper towels. The table below shows the cost for each item, including tax. Veronica gave the cashier a $10.00 bill. The cashier handed her 3 quarters and 4 pennies in change. Veronica thought she should have received more change.
Which mathematical explanation best supports Veronica's claim?
The cashier scanned the milk twice.
The cashier scanned the bread twice.
The cashier handed out 4 pennies instead of 4 dimes.
The cashier did not scan the dishwashing liquid.
Answer:
Cashier scanned the bread twice.
Step-by-step explanation:
= 2.49 + 2.19 + 1.47 + 0.87 = 7.02
= 7.02 + 0.75 = 7.77
= 7.77 + 0.04 = 7.81
With 2 dollars and 19 cents leftover, even if the pennies were changed to dimes, youd still have only get up to 8.17 which still leaves 1 dollar and 83 cents leftover.
With that eliminated what could have the cashier miss-scanned? The paper towels are incorrect because 1.47 + 7.81 doesnt make 10 dollars
The dishwashing liquid isn't right either, because 0.87 + 7.81 doesn't make 10 dollars aswell.
The milk is also incorrect because 2.49 + 7.81 doesnt make EXACTLY 10 dollars. The bread is to correct answer bevause 2.19 + 7.81 equals exactly 10 dollars.
Hope this helps :)

15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from Con<br />AB is 4.5 cm find its area.
Answer: The area of the parallelogram ABCD = 32.4 sq. cm
Step-by-step explanation:
Given: In parallelogram ABCD, AB = 7.2 cm and the perpendicular drawn from C (altitude) on AB is 4.5 cm i.e.e height =4.5 cm.
Area of parallelogram = [tex](Base \times height)[/tex]
Then, Area of parallelogram ABCD = [tex]7.2\times4.5[/tex]
= [tex]32.4\ cm^2[/tex]
Therefore , the area of the parallelogram ABCD = 32.4 sq. cm
which equation describes a line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3?
Answer:
The equation of the line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:
[tex]y=-\frac{5}{2}x+13[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the line
y=2/5x+3
comparing with the slope-intercept form of the line equation
Thus, the slope of the line is: m = 2/5
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 2/5
Thus, the slope of the the new perpendicular line = – 1/m = [-1]/[2/5] = -5/2
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the slope of perpendicular line m = -5/2 and the point (4, 3)
[tex]y-3=-\frac{5}{2}\left(x-4\right)[/tex]
Add 3 to both sides
[tex]y-3+3=-\frac{5}{2}\left(x-4\right)+3[/tex]
[tex]y=-\frac{5}{2}x+13[/tex]
Therefore, the equation of the line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:
[tex]y=-\frac{5}{2}x+13[/tex]Plis help and I’ll give brainly

Lin and Elena have discovered they have so much in common. They each have a fish tank holding 20 units of water. Whose tank holds 20 gallons, and whose holds 20 cups?
Answer: a. Lin's tank hold 20 cups and Elena's tank hold 20 gallons; I know this because gallons are greater than cups.
Step-by-step explanation:
Gallons are greater than cups so the fish tank that will hold 20 gallons would have to be the bigger one which in this case is Elena's.
With cups being lesser in quantity than gallons, the fish tank that will hold 20 cups of water will definitely have to be the smaller one which in the case is Lina's.

AB = BC
AC is the opposite side of ∠2.
BC is the opposite side of ∠1.
Opposite sides of equal angles are equal.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
∠3 = ∠1
From the figure, we see that,
∠3 and ∠2 are vertical angles.
Vertical angles are equal.
Now,
∠2 = ∠1
AC is the side opposite to ∠2.
BC is the side opposite to ∠1.
The sides that are opposite to equal angles are also equal.
Thus,
AC and BC are equal.

In parallelogram ABCD, diagonals AC------- and BD------- intersect at point E, AE = x + 16, and CE=5x
What is AC?
Enter your answer in the box.
Answer:
AC = 40
Step-by-step explanation:
A quadrilateral is a polygon shape with four sides and four angles. The interior angle of a quadrilateral sums up to 360°.
A parallelogram is a quadrilateral (has four sides and four angles) in which has two pair of opposite sides are parallel to each other. The diagonals of a parallelogram bisect each other.
Given parallelogram ABCD:
Diagonals AC and BD bisect each other at point E. Hence:
AC = AE + CE (line segment addition postulate)
Also:
AE = CE (diagonal BD bisects AC at point E).
Hence; x + 16 = 5x
5x - x = 16
4x = 16
x = 4
AE = x + 16 = 4 + 16 = 20; CE= 5x = 5(4) = 20
AC = AE + CE = 20+ 20 = 40

Linear equation: 5(3x+9) -2x = 15x - 2 (x-5)
Answer:
There are no solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
5(3x+9)−2x=15x−2(x−5)
Step 1: Simplify both sides of the equation.
5(3x+9)−2x=15x−2(x−5)
(5)(3x)+(5)(9)+−2x=15x+(−2)(x)+(−2)(−5)(Distribute)
15x+45+−2x=15x+−2x+10
(15x+−2x)+(45)=(15x+−2x)+(10)(Combine Like Terms)
13x+45=13x+10
13x+45=13x+10
Step 2: Subtract 13x from both sides.
13x+45−13x=13x+10−13x
45=10
Step 3: Subtract 45 from both sides.
45−45=10−45
0=−35

Whose statement makes sense? Whose statement is nonsense? Carla said The shaded angle represents 1/4 of the circle, Adam states the shaded angle represents 3/8 of the circle
Step-by-step explanation:
The attached figure shows a circle. In this circle, some of the part is shaded with a color.
In the figure, we have drawn lines from red color. It shows that there is 1 part shaded out of 4 parts.
Carla said The shaded angle represents 1/4 of the circle while Adam states the shaded angle represents 3/8 of the circle.
The fraction for the shaded part is 1/4. Hence, Carla is correct.
