negative

Answer:

70!

Step-by-step explanation:

If you divide the shape in rectangles, you'll just add it up in the end.

5 x 3 = 15

5 x 3 = 15

10 x 4 = 40

40 + 15 + 15 = 70.

Hope this helps!

Answer:

Step-by-step explanation:

If angles C and B have equal degrees then the side AC is also equal to  side AB in length and you can make their equations equal as well and solve for X.

2x+16=7x+6

get X's all on same side and the constants all on the other side,  

-2x +2x+16=7x+6+-2x

The X's on the left cancel out.

16=5x+6

-6+16=5x+6+-6

add -6 to each side.  On the right the 6 is now cancelled out.

10=5X

divide each side by 5 to cancel out the 5

10/5= 5X/5

2=X .  ANSWER

Step-by-step explanation:

The value of w from the given triangle VWX is 5 units. Therefore, option D is the correct answer.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c

From the given triangle VWX, ∠X=51°, ∠W=16° and VW=x=14.

Here, sinX/x=sinW/w

sin51°/14=sin16°/w

0.7771/14=sin16°/w

0.7771/14=0.2756/w

0.0555=0.2756/w

w=0.2756/0.0555

w=4.965

w≈5

Therefore, option D is the correct answer.

b=21x+8

Step-by-step explanation:

she sell bags 21 dollars for every bag(x) and they only add 8 dollars 1 time

let x be how much longer she can run the race and still beat her previous time

55(min) + x(min) < 1(hr) + 10(min)

55(min) + x(min) < 60(min) + 10(min)

55 + x < 60 + 10

x < 60 + 10 - 55

x < 15(min)

The Perimeter of Equilateral triangle = 60cm

According to the question,

To find the height of the triangle,

Perimeter of Equilateral triangle = Area of Equilateral triangle.

[tex]60 = \frac{ \sqrt{3} }{4} a {}^{2} \\ [/tex]

[tex]60 \times 4 = \sqrt{3a {}^{2} } [/tex]

[tex]a {}^{2} = 240 \sqrt{3} \\ [/tex]

[tex]a = 120 \sqrt{3} cm[/tex]

Answer:

b = 3

Step-by-step explanation:

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other:

First, distribute 3 to all terms within the parenthesis:

3(3x + 1) =

3 * 3x = 9x

3 * 1 =  3

9x + b = 9x + 3

Isolate the variable, b. Subtract 9x from both sides:

9x (-9x) + b = 9x (-9x) + 3

b = 3

3 is your value for b.

Answer:

[tex]m = -\frac{2}{3}[/tex]

Step-by-step explanation:

Given

[tex]2x+3y=12[/tex]

[tex]4x-3y=15[/tex]

Required

Slope of #1

[tex]2x+3y=12[/tex]

Make y the subject

[tex]3y = -2x + 12[/tex]

Divide through by 3

[tex]y = -\frac{2}{3}x + \frac{12}{3}[/tex]

[tex]y = -\frac{2}{3}x + 4[/tex]

An equation has the form:

[tex]y = mx + c[/tex]

Where

[tex]m = slope[/tex]

Compare [tex]y = mx + c[/tex] and [tex]y = -\frac{2}{3}x + 4[/tex]

[tex]m = -\frac{2}{3}[/tex]

Hence, the slope is [tex]-\frac{2}{3}[/tex]

Answer: x-intercepts (5,0), (2,0), (1,0)

y-intercept (0,-10)

Step-by-step explanation: If one factor of the polynomial function is (x-5), then the function f(x) can be factored in the following way: (x-5) (x^2-3x+2)

Now factor the trinomial: (x-2) (x-1)

Thus, x-intercepts (points where f(x)=0) are

x1=5

x2=2

x3=1

and y-intercept (point where x=0) is

f(0)=0^3-8.0^2+17.0-10=-10.

plz mark me brainliest

A function assigns the values. The y-intercept of the function is -10, while the x-intercept of the function is 5, 2, and 1.

A function assigns the value of each element of one set to the other specific element of another set.

To find an intercept of the function, we need to substitute the value of x or y depending on the intercept as 0 in the function. Therefore, the x-intercept of the function is,

y = (0)³ - 8(0)² + 17(0) - 10

y = -10

Since given that one factor of the function f(x)=x³-8x²+17x-10 is (x-5). Therefore, if the function f(x) is divided by (x-5). The quotient will be x²-3x+2.

Now, Factorising the given expression x²-3x+2.

x²-3x+2

= x² - 2x - x + 2

= x(x-2) -1(x-2)

= (x-2)(x-1)

Now, we can write the function f(x)=x³-8x²+17x-10 as y=(x-5)(x-2)(x-1). Therefore, the x-intercept of the function is,

x-intercept = 5, 2, 1

This can be verified from the graph formed below.
