Give the least common
multiple:
3a, 15

Answer:

Graph is below.

Step-by-step explanation:

The solutions of the equations are : x = [8 ± √ 40] / 4

Given,

Y=2x² - 8x+3

Now,

To get the solution of equation equate it to 0 .

2x² - 8x+3  = 0

By quadratic formula,

x = -b ± √ b² - 4ac/2a

Substitute the values in the formula,

x = [8 ± √ 64 - 4(2)(3)] / 2* 2

x = [8 ± √ 40] / 4

Now plot the points in the graph. The graph is attached below.

Answer:

7 squares

Step-by-step explanation:

Key skills: Counting, Averages

1) Based on what I counted, there are 11 columns, and 53 squares. If you want an average of 5 squares per column and you have 12 columns, the total number of squares you want is 60.

2) Since there are already 53 squares present, you need 60-53 = 7 squares more.

Hope you understood and have a nice day!!

Answer:

x = 21

Step-by-step explanation:

For the complementary angles, the sum of two angles is equal to 90 degrees.

ATQ,

3x+2+x+4 = 90

Taking like terms together,

3x+x+6=90

4x+6=90

4x = 84

x = 21

So, the value of x is equal to 21.

Step-by-step drip check:

The name of the formula you get if you solve for P could be "Principal (loan amount)" "Term of the loan (in months)" or "Number of monthly payments"

Logarithms;

[tex]n = \dfrac{ ln[1 - \dfrac{Pr}{M} ]}{ln(1+r)}[/tex]

Consider the monthly payment formula

[tex]M= \dfrac{Pr(1+r)^n}{(1+r)^n-1}[/tex]

where: M = monthly payment.

P = principal loan amount.

r = interest rate per month (in decimal form).

n = term of the loan (in months).

If we will solve for P, the name of the formula is "Principal (loan amount)".

If we solve for n, the formula is "Term of the loan (in months)" or "Number of monthly payments".

When solving for n, we have to use logarithms:

[tex]M (1+r)^n-1=Pr(1+r)^n\\\\\dfrac{1}{ (1+r)^n} = 1 - \dfrac{Pr}{M} \\\\ln\dfrac{1}{ (1+r)^n} = ln[1 - \dfrac{Pr}{M} ]\\\\\\n = \dfrac{ ln[1 - \dfrac{Pr}{M} ]}{ln(1+r)}[/tex]

Answer:

let the angle be x and the complementary angle be y

so, x+y=90 and given,

x=y-80

solving both the equations,

x = 5

y = 85

so the angles are 5 and 85

Answer:

[tex]Q=(9,11)[/tex]

Step-by-step explanation:

Solving (4a)

[tex]P (x_1,y_1) = (1,1)[/tex]

[tex]M (x,y) = (5,6)[/tex]

Required

Determine [tex]Q(x_2,y_2)[/tex]

To do this, we make use of the mid-point formula:

[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Substitute values for x, y, x1 and y1

[tex](5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2})[/tex]

Multiply through by 2

[tex]2 * (5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2}) * 2[/tex]

[tex](10,12) = (1+x_2,1+y_2)[/tex]

By comparison:

[tex]10 = 1 + x_2[/tex]

[tex]x_2 = 10 - 1[/tex]

[tex]x_2 = 9[/tex]

[tex]12 = 1 + y_2[/tex]

[tex]y_2 = 12 - 1[/tex]

[tex]y_2 = 11[/tex]

Hence, the coordinates of Q is (9,11)

Answer:

[tex]y = \frac{-7}{3}x -12[/tex]

Step-by-step explanation:

Point-slope form is [tex]y-y_1= m (x-x_1)[/tex]. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] have to be substituted for with real values in order to make an equation of a line. From there, you can isolate [tex]y[/tex] to turn it into slope-intercept form.

1) First, let's find the slope of the line, which is represented by the variable [tex]m[/tex]. Use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values of one point, [tex]x_2[/tex] and [tex]y_2[/tex] are the x and y values of another point. For this problem, let's use the given points (-3, -5) and (-6, 2):

[tex]\frac{(2)-(-5)}{(-6)-(-3)} \\= \frac{2+5}{-6+3} \\= \frac{7}{-3}[/tex]

Thus, the slope is [tex]\frac{7}{-3}[/tex].

2) Now that we have the slope, let's substitute it into the point-slope formula. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point that the line intersects so you could either use (-3, -5) or (-6,2), but for this answer, I used (-6,2). (The answer will always be the same no matter which point you choose.) Substitute these values then isolate y to put it in slope-intercept form:

[tex]y-(2) = \frac{-7}{3} (x-(-6))\\y -2 = \frac{-7}{3} (x+6)\\y-2 = \frac{-7}{3}x-\frac{42}{3} \\y -2 = \frac{-7}{3}x-14\\y = \frac{-7}{3}x-12[/tex]

So, [tex]y = \frac{-7}{3}x -12[/tex] is the answer.

Let

x------> height of Leon's older brother

y------> height of Leon

Convert mixed number to an improper fraction

4\frac{3}{4}\ ft=\frac{4*4+3}{4}= \frac{19}{4}\ ft443 ft=44∗4+3=419 ft

we know that

x=\frac{19}{4}\ ftx=419 ft -----> equation A

y=x-\frac{1}{3}y=x−31 -----> equation B

substitute equation A in equation B

y=\frac{19}{4}-\frac{1}{3}=\frac{53}{12}\ fty=419−31=1253 ft

Convert to mixed number

\frac{53}{12}=\frac{48}{12}+\frac{5}{12}=4\frac{5}{12}\ ft1253=1248+125=4125 ft

therefore

the answer is

4\frac{5}{12}\ ft4125 ft
