Answer:

Step-by-step explanation:

I assume the equation is

[tex]\dfrac6{x^2+2x-15}+\dfrac7{x+5}=\dfrac2{x-3}[/tex]

Notice that

[tex]x^2+2x-15=(x+5)(x-3)[/tex]

so to get each fraction to have a common denominator, we need to rewrite

[tex]\dfrac7{x+5}=\dfrac{7(x-3)}{(x+5)(x-3)}=\dfrac{7x-21}{x^2+2x-15}[/tex]

and

[tex]\dfrac2{x-3}=\dfrac{2(x+5)}{(x+5)(x-3)}=\dfrac{2x+10}{x^2+2x-15}[/tex]

So we have

[tex]\dfrac6{x^2+2x-15}+\dfrac{7x-21}{x^2+2x-15}=\dfrac{2x+10}{x^2+2x-15}[/tex]

Combine the fractions and put them on one side:

[tex]\dfrac{6+(7x-21)-(2x+10)}{x^2+2x-15}=0[/tex]

If x ≠ -5 and x ≠ 3, we can ignore the denominator, leaving us with

[tex]6+(7x-21)-(2x+10)=0[/tex]

[tex](6-21-10)+(7x-2x)=0[/tex]

[tex]-25+5x=0[/tex]

[tex]5x=25[/tex]

[tex]x=\dfrac{25}5=\boxed{5}[/tex]

Answer:

The answer is 31

Step-by-step explanation:

ZTB= 31

The measure of angle ∠ZTB of triangle SRT is 31°.

A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.

For the given situation,

Let S R T be a triangle, and point Z is the in center of triangle S R T.

Lines are drawn from point Z to the sides of the triangle to form right angles and line segments Z A, Z B, and Z C as shown in the below figure.

Here, ∠ AZR = 35°, ∠ZRC = 35°, ∠ BSZ = 24°, ∠ZSA = 24°, ∠ZTB = ?

The in center of a triangle is the intersection point of all the three interior angle bisectors of the triangle. It can be defined as the point where the internal angle bisectors of the triangle cross.

According to the angle bisector theorem,

⇒ [tex]\angle ZRC = \angle ARZ[/tex]

⇒ [tex]\angle ARZ = 35\degree[/tex]

Let the unknown angle, ∠ZTB be x. Then ∠BTC = 2x

The sum of the interior angles of a triangle is equal to 180°,

So, [tex]24+24+35+35+2x=180[/tex]

⇒ [tex]118+2x=180[/tex]

⇒ [tex]2x=180-118[/tex]

⇒ [tex]x=\frac{62}{2}[/tex]

⇒ [tex]x=31[/tex]

Hence we can conclude that the measure of angle ∠ZTB of triangle SRT is 31°.

Answer:

x = 13

Step-by-step explanation:

x represent a number

Decrease means subtract

x-32

Is means equals

x-32 =

33 minus 4 times the number

33 - 4x

x-32 =33 - 4x

Add 4x to each side

x -32+4x = 33-4x+4x

5x -32 = 33

Add 32 to each side

5x-32+32 =33+32

5x = 65

Divide by 5

5x/5 = 65/6

x = 13

Given:

Jayla says that the equation [tex]y=2x-3[/tex] matched the graph.

To prove:

Jayla is correct

Solution:

We have,

[tex]y=2x-3[/tex]      ...(i)

The ordered pairs are (3,3), (4,5), (5,7).

We need to substitute the ordered pairs into the equation to prove that Jayla is correct.

For point (3,3), put x=3 and y=3 in (i).

[tex]3=2(3)-3[/tex]

[tex]3=6-3[/tex]

[tex]3=3[/tex]

[tex]LHS=RHS[/tex]

So, point (3,3) lies on the line [tex]y=2x-3[/tex].

For point (4,5), put x=4 and y=5 in (i).

[tex]5=2(4)-3[/tex]

[tex]5=8-3[/tex]

[tex]5=5[/tex]

[tex]LHS=RHS[/tex]

So, point (4,5) lies on the line [tex]y=2x-3[/tex].

For point (5,7), put x=5 and y=7 in (i).

[tex]7=2(5)-3[/tex]

[tex]7=10-3[/tex]

[tex]7=7[/tex]

[tex]LHS=RHS[/tex]

So, point (5,7) lies on the line [tex]y=2x-3[/tex].

All three point (3,3), (4,5), (5,7) satisfy the given equation.

Therefore, jayla is correct. Hence proved.

Answer:

[tex]\displaystyle A+B=-\frac{5}{4}[/tex]

Step-by-step explanation:

The Number Line

Let's call

[tex]\displaystyle A=-4\frac{1}{2}[/tex]

[tex]\displaystyle B=+3\frac{1}{4}[/tex]

Both numbers are given as mixed fractions. Let's convert them to improper fractions:

[tex]\displaystyle A=-4\frac{1}{2}=-(4+\frac{1}{2})=-\frac{8+1}{2}=-\frac{9}{2}[/tex]

[tex]\displaystyle B=3\frac{1}{4}=3+\frac{1}{4}=\frac{12+1}{4}=\frac{13}{4}[/tex]

The decimal values are A = -9/2=-4.5, B=13/4 = 3.25

Now represent the points in the number line. See the image below

Finally, calculate their sum:

[tex]\displaystyle A+B=-\frac{9}{2}+\frac{13}{4}[/tex]

[tex]\displaystyle A+B=-\frac{18}{4}+\frac{13}{4}=\frac{-18+13}{4}[/tex]

[tex]\boxed{\displaystyle A+B=-\frac{5}{4}}[/tex]

Answer:11.99%

Step-by-step explanation:

The Actual present value is $85.74.

Fees associated with the loan are not included in the interest rate. The cost of borrowing money each year, including fees, is stated as an annual percentage rate (APR).

We have,

Christina is considering buying a new car with a sticker price of $23,599.

Total cost = (107.25 x 79.95)/ 100

Answer-

The slope of the line that passes through the points is

Solution-

As there is a single line passing through all these points, so taking any two points and then applying the formula for slope will give the slope of the line.

The points are,

(-14, 8), (-7, 6), (0, 4), (7, 2), (14, 0)

Taking two points as, (0, 4), (7, 2)

x₁ = 0

y₁ = 4

x₂ = 7

y₂ = 2

Putting the values,

Therefore, the slope of the line that passes through the points is

Step-by-step explanation:

The slope of the line that passes through the points in the table is -2/7.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given a table which shows the points on the line.

Slope of a line passing through two points (x, y) and (x', y') is,

Slope = (y' - y) / (x' - x)

Take any two points on the line.

(0, 4) and (7, 2).

Slope = (2 - 4) / (7 - 0) = -2/7

Hence the slope of the line is -2/7.

Weight gain per day = 200 pounds

Weight gained by a whale since birth = [tex] 7*10^3 [/tex] pounds

Number of days of the whale = [tex] \frac{7*10^3}{200} = \frac{7*10*10*10}{200} [/tex]
