Answer:

The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is​ [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]

Step-by-step explanation:

We need to find the slope-intercept equation of the line that goes through the points (1, 5) and (2, 8)

The general equation for slope intercept form is ​ [tex]y=mx+b[/tex] where m is slope and b is y-intercept

Finding slope

Slope can be found using formula [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x _1=1, y_1=5, x_2=2, y_2=8[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-5}{2-1}\\Slope=\frac{3}{2}[/tex]

So, we get slope [tex]m=\frac{3}{2}[/tex]

Finding y-intercept

y-intercept can be found using slope [tex]m=\frac{3}{2}[/tex] and point (1,5)

[tex]y=mx+b\\5=\frac{3}{2}(1)+b\\b=5- \frac{3}{2}\\b=\frac{10-3}{2}\\b=\frac{7}{2}\\[/tex]

So, we get y-intercept [tex]b=\frac{7}{2}[/tex]

Equation of line

So, equation of line having slope [tex]m=\frac{3}{2}[/tex] and y-intercept [tex]b=\frac{7}{2}[/tex] is:

[tex]y=mx+b\\y=\frac{3}{2}x+\frac{7}{2}[/tex]

The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is​ [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Answer:

First question: Answer is C

Second question: Answer is C

Third question: Answer is A

Step-by-step explanation:

For the first question, the option is C since there were 5 interviewees per week, which gives a total of 5x12 = 60, that is, an exact sample population of 60.

For the second question, the exact population is of all the 250,000 households that are being contacted by the ACS.

For the third question, the population is 1161 American adults who if they provide information about the political party that they believe has better ideas to lead the country in the 21st century,

Answer:

−12√3−6√5 or Decimal: -34.201018

Step-by-step explanation:

-3√12-2√27-2√45

3√12=6√3

2√27=6√3

2√45=6√5

=6√3-6√3-6√5

=−12√3−6√5

Answer:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Step-by-step explanation:

Answer:

x1 = x 61 = 6

x0 = 1 70 = 1

x-1 = 1/x 4-1 = 1/4

xmxn = xm+n x2x3 = x2+3 = x5

xm/xn = xm-n x6/x2 = x6-2 = x4

(xm)n = xmn (x2)3 = x2×3 = x6

(xy)n = xnyn (xy)3 = x3y3

(x/y)n = xn/yn (x/y)2 = x2 / y2

x-n = 1/xn x-3 = 1/x3

Answer:

y= 1x-5

Step-by-step explanation:

This grpah shows a linear equation, for which the formula is y=mx+b. M is the slope, and b is the y-intercept, which means the point on the y-axis when x is zero.

So far= y=_x-5

Now to find the slope, you can take 2 points and use the slope formula, which is [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

I used the points (1,-4) and (0, -5)

(1,-4)

[tex]x_{2} , y_{2}[/tex]

(0,-5)

[tex]x_{1} ,y_{1}[/tex]

Plug into formula

[tex]\frac{-4-(-5)}{1-0}[/tex]

negative minus negative becomes a positive

[tex]\frac{-4+5}{1}[/tex]

[tex]\frac{1}{1}[/tex]

The slope is 1, so the equation of the graph is

y= 1x-5

Answer:A

Step-by-step explanation:A

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.

Answer:

Linear equations take the form: y = mx + c

y is the dependent variable i.e the money that Naomi has to pay in total.

x is the independent variable which in this case is weeks.

m is the slope and this shows the change as a result of x. It should therefore represent the weekly payment as this is increases per week.

c is a the y-intercept which means its a fixed figure that doesn't change. It will therefore be the down payment because that does not change.

Plan A:

Naomi wants to pay $840. Using the formula format and explanation above (replace x with w so it makes more sense), the formula will be:

840 = 60w + 180

Plan B:

This has no down payment so there will be no y-intercept.

840 = 70w

Answer:

b = 12 cm

Step-by-step explanation:

The Pythagora's Theorem

The area of a square of side length x is

[tex]A = x^2[/tex]

We have three squares, two of which have side lengths of a=5 cm and b= 13 cm.

The combined area of the smaller squares is the same as the area of the largest square. We cannot say at first sight which square is the largest, we'll assume the square of side length of 13 cm is the largest one. Thus:

[tex]5^2+b^2=13^2[/tex]

Where b is the unknown side length.

The above expression corresponds to the Pythagora's Theorem formula. Solving for b:

[tex]b^2={13^2-5^2=169-25=144[/tex]

[tex]b=\sqrt{144}[/tex]

b = 12 cm

Step-by-step explanation:

Given system of equations are :

-3y = x+5 ....(1)

y = 2x+2 ...(2)

We need to find the solution of the equations.

Multiply equation (2) by 2.

-6y = 2x+10 ...(3)

Subtract equation (2) and (3).

y-(-6y)= 2x+2-(2x+10)

7y=2x+2-2x-10

7y=-8

y = 8/7

Put the value of y in equation (2)

[tex]\dfrac{8}{7}=2x+2\\\\\dfrac{8}{7}-2=2x\\\\x=\dfrac{\dfrac{-6}{7}}{2}\\\\x=\dfrac{-3}{7}[/tex]

Hence, this is the required solution.
