Write an equation for (-1,-2),(-3,-4)

Answers

Answer:

y=x+1

Step-by-step explanation:

First find the slope by subtracting the y values from both points and dividing it by the subtraction of the x values from both points:

-4--2/ -3--1= -2/-2= 1

so the slope is 1

Now find the y-intercept by plugging in the x and y from one of the points into the equation y=x+b

-3=-4+b

1=b

now plug the slope and y intercept in:

y=x+1

Answers

Answer:

100

Step-by-step explanation:

Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.

Since the sum of angles in a triangle is 180.

180-(25x2) will give you the last angle in one of the triangles.

The other angle is identical so the angle at the top of the other triangle will also be 130.

The sum of angles in a circle is 360.

Therefore, angle x = 360-(130x2)

X= 100

Solve this system of linear equations. Separate the x- and y- values with a comma.
17x = 43 - 15y
8x = -68 + 15y

Answers

Answer:

(-1,4)

Step-by-step explanation:

Using elimination, add the two equations to get rid of the y variable.

17x = 43 - 15y

+8x = -68 + 15y

=25x = -25

x = -1

Now plug in -1 for x in any of the equations.

17(-1) = 43 - 15y

-17 = 43 - 15y

-60 = -15y

y = 4

Answers

Answer:

y=70°

z= 60°

w= 70°

Step-by-step explanation:

Since the two triangles are similar, we know that all of the corresponding angles must be the same.  On the triangle on the left, we can see that the angle formed between sides AB and AC is 60°.  This means that the same angle is formed at Z, which is in the same location on the triangle to the right.  From there, we can find the missing angle, W, from the difference of 180°.

180°-50°-60°=70°.

The same way we found Z, we can also find Y, since it has to be the same as W.

Using the information presented, write a short passage to support the claim that many Hox genes are regulatory genes.The genome of an organism can be many millions of base pairs long. Genes are regions of the chromosome that code for protein products. They are scattered throughout the chromosome with little logical reason for their placement. There is an exception to this disorderHox genes, which are a family of genes that produce transcription factors. Hox genes are found in most eukaryotes. They are clustered together in the genome and always found in a particular order. The genes are in the same order as the characteristics are found along the body axis in the organism itself. These genes specify segment placement, such as whether a segment will form part of the head, thorax, or abdomen. For example, Hox genes related to structures in the head of an organism are found first in the Hox cluster.Hox genes have been studied in fruit flies. A cluster of 8 Hox genes are activated very early in development, laying out the segmented body plan of the head, thorax, and abdomen. There are very clear boundary lines of expression for each Hox gene. In fact, forcing embryonic Hox gene expression in a wrong part of the body can cause another regions body parts to develop. Scientists created a fly that had legs where its antennae should be through induced Hox expression! 50 PTS Simplify Please Lainey bought a set of 20 markers for $6What is the cost of 111 marker?
