A line passes through the points A(–1, 7) and B(1, 3). b Write an equation

Answers

Answer 1

Answer:

y=-2x+5

Step-by-step explanation:

First, find the slope:

m=(y2-y1)/(x2-x1) ==> slope formula where m is the slope

(–1, 7), (1, 3) ==> (x1=-1, y1=7), (x2=1, y2=3)

m=(3 - 7)/(1 - (-1)) ==> plugin y2=3, y1=7, x2=1, and x1=-1 into the slope formula

m=(-4)/(1 + 1) ==> simplify

m=(-4)/2

m=-2 ==> the slope is -2

y=mx+b ==> slope-intercept equation

3=(-2)(1)+b ==> plugin the slope(m=-2) and point B(1, 3) ==> (x=1, y=3)

3=-2+b ==> solve for b

3+2=-2+2+b ==> add 2 on both sides to isolate b

b=5 ==> simplify

y=-2x+5 ==> plugin the slope and b=5 into the equation

Un albañil pone azulejos a una pared de 6 m de largo y 2,4 m de alto.Los azulejos son cuadrados de 20 cm de lado

Answers

Pregunta completa:

Un albañil pone azulejos a una pared de 6 m de largo y 2,4 m de alto. Los azulejos son cuadrados de 30 cm de lado. ¿Cuants, cajas tendra que comprar si en una caja hay 25 azulejos? Con procedimiento.

Respuesta:

160 tejas

7 cajas

Explicación paso a paso:

Dimensión de la pared = 6 m por 2,4 m

Área de la pared = 6 m * 2,4 m

Área de la pared = 14,4 m²

Longitud lateral, s de teja cuadrada = 30 cm = 0,3 m

Área de la loseta cuadrada = s² = 0.3² = 0.09m²

Número de baldosas cuadradas necesarias:

14,4 m² ÷ 0,09 m²

= 160 fichas cuadradas

Si hay 25 fichas en una caja;

Número de cajas a comprar:

160/25

= 6,4 ≈ 7 cajas

Answers

Answer:

The measure of the obtuse angle marked UVW is 108

Step-by-step explanation:

Here, we want to get the measure of the angle marked UVW

To get this, we refer to the given diagram

From the diagram;

UVW = UVX + XVW

UVW = 68 + 40

UVW = 108 degrees

What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0

Answers

Answer:

b = -9

Step-by-step explanation:

Given the equation (−34 + 43)+ b = 0

We are to find the value of b

First solve for the value in parenthesis

(−34 + 43)+ b = 0

9+b = 0

Subtract 9 from both sides

9+b-9 = 0 - 9

b+0 = -9

b = -9

Hence the value of b will make the equation a true statement is -9

A bat was flying for four and a half hours at a constant speed of ten kilometers per hour. How far did the bat travel in meters?

Answers

Answer:

45000 m

Step-by-step explanation:

Speed = distance / time

10 km/h = distance / 4.5 hours

distance = 10 x 4.5 = 45 km

Kilometre needs to be converted to metres

Ikm = 1000m

45 x 1000 = 45,000m

Find area of the figure. PLEASE HELP!

Answers

Answer:

Step-by-step explanation:

Answer:

69 m²

Step-by-step explanation:

The figure is composed of 2 right triangles

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

A of triangle on left is

A = [tex]\frac{1}{2}[/tex] × 9 × 10 = 45 m²

A of triangle on right is

A = [tex]\frac{1}{2}[/tex] × 8 × 6 = 24 m²

Total area = 45 + 24 = 69 m²

Finally, you will determine how the gene was changed and how it affected the person's phenotype.

First, circle the mutation() on cach of the three mutared strands that differ from the original DNA strand at the top of your form. (Note: not all sequences start at beginning of gene.) . Second, lightly shade over cach codon that differs in the mRNA strand from the original mRNA strand at the top of your form Lastly, lightly shade over each amino acid that differs in the amino acid sequence from the original amino acid sequence at the top of your form .
