Write The Algebraic Expression That Matches Each Graph. 20 POINTS + BRAINLEIST

Answers

Answer 1

Answer:

Step-by-step explanation:

The (positive) slope of the line whose domain is (-infinity, -1) is

m = rise/run = 1/1, or m = 1.  The (negative) slope of the other line segment is

m = rise/run = -1/1, or m = -1.

Let's now find the equation of the line with m = 1.  Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2.  Then the equation is y = x + 2 on the domain (-infinity, -1).

Now find the equation of the line with negative slope:

y = -x + b; the y-intercept is immediately evident from the graph as b = 0.

Then the desired eequation is y = -x on the domain (-1, infinity).

write an expression to represent the area of the flag as the product of the flags length and width

Answers

Answer:

A = l * w

Step-by-step explanation:

the length times width would be the area, so just make variables of each thing and then you are good! It would be important to note any more information that is given, like the ratio of the length and the width, in which case just add the respective coefficients based on the ratio (e.g 3:2 would mean 3l * 2w = A). Hope this helps!

Answers

Mike has 3 brothers and 3 sisters

Kate has 4 brothers and 2 sisters

all the girls in the family are 3

hope it helps...!!!

So mike has one more sister and one less brother than Kate (he is Kate’s brother)’ thank Kate (Kate is his sister) and Kate has one less sister than mike
So Kate has to have at least three brothers because mike has the same amount of sisters as brothers and Kate is an extra sister,
So mike has three sisters and Kate has two sisters because she is a sister and two times two is four, so mike has three brothers, but there fr four boys in total
So Kate has two sisters and four brothers (mikes brothers+1)
Mike has three brothers and three sisters (Kate’s sisters plus one)
FINAL ANSWER: 4 brothers and 3 sisters

b) Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning. (1 point)


c) Is triangle DCA congruent to triangle BCA? Explain. (2 points)

Answers

Answer:

B) No, supplementary angles are either of two angles whose sum is 180 degrees.

C) Yes, the triangles are congruent because the triangles have exactly the same size and shape

Step-by-step explanation:

B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.

C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Peyton and James each bought a large cookie cake. The cookie cakes are
the same size.
Peyton cut his cookie cake into 12 slices.
James cut his cookie cake into 6 slices and ate 4 slices.
Together Peyton and James ate 10
12 of one cookie cake.
How many slices of cake did Peyton eat?
A 1 slice
B 2 slices
C 3 slices
D 4 slices

Answers

Answer:

2 slices.

Step-by-step explanation:

Let's say that James' cake is essentially one half of Peyton's cake. 6 x 2 is 12, and 4 x 2 is 8. So James' must have eaten 8 slices while Peyton ate 2.

I’m pretty sure it would be B 2 slices because James is really eating 8 slices because his are cut in 1/6

Answers

Answer:

4y-2 / 3

Step-by-step explanation:

let’s find the y intercept

set x to zero to get y=3/4(0) +1/2

multiply 3/4 and 0 to get y=1/2

so the x value is 0 and the y value is 1/2

the ordered pair would be (0, 1/2)

there’s others but this is probably the easiest one to find

Help me I am a stone when it comes to absolute value in problems—
Explination too please

Answers

Answer:

31.) you put a dot on one and go to the right

32.) you put a dot on ten and go to the left

Step-by-step explanation:

the absolute value part is honestly just to throw u off, it also helps if you read it aloud. so for example in # 31. is saying the absolute value of b minus 5 is greater or equal to 1, you could also think of it as any number is greater or equal to one. hope that helps!

when dealing with an absolute value expression, let's keep in mind that the expression once we remove the bars it has a ± version, so if the expression were say hmmm |a + b| = 25, if we remove the bars we really have a duet, namely ±(a + b) = 25, same if we had |a + b| > 25, then ±(a + b) > 25.

Tis noteworthy, that unlike "equalities", inequalities vary mainly on that, when we divide or multiply or exponentialize by a negative value, the inequality sign does a horizontal flip, it changes, so let's proceed

[tex]\boxed{31}\\\\ |b-5|\geqslant 1\implies \pm(b-5)\geqslant 1\implies \begin{cases} +(b-5)\geqslant 1\\ b\geqslant 6\\[-0.5em] \hrulefill\\ -(b-5)\geqslant 1\\ b-5\stackrel{\stackrel{notice}{\downarrow }}{\leqslant} -1\\ b \leqslant 4 \end{cases}~\hfill 6~~\leqslant ~~ b~~\leqslant ~~4[/tex]

[tex]\boxed{32}\\\\ |-2r|\leqslant 10\implies \pm(-2r)\leqslant 10\implies \begin{cases} +(-2r)\leqslant 10\\ -2r\leqslant 10\\ r\stackrel{\stackrel{notice}{\downarrow }}{\geqslant} \cfrac{10}{-2}\\\\ r\geqslant -5\\[-0.5em] \hrulefill\\ -(-2r) \leqslant 10\\ 2r \leqslant 10\\ r\leqslant \cfrac{10}{2}\\\\ r \leqslant 5 \end{cases}~\hfill -5~~\leqslant~~ r ~~\leqslant~~5[/tex]

Explanation:

V(R) = 8m3
Volume of a triangular prism (T): base area X
height
Base area = 1/2 x base × height (of the triangular base)
A = 1/2 x1x 3.5 = 1.75m2
Back with the volume formula:
V (T)= Ax h= 1.75 x 2 = 3.5m3
Adding both volumes:
