Answer:

  (1, -5)

Step-by-step explanation:

Here, it is easy to check the offered choices. We find the first one works, so our check is short.

For (x, y) = (1, -5)

  3·1 +10·(-5) = 3 -50 = -47 . . . yes

  5·1 -7·(-5) = 5 +35 = 40 . . . yes

__

Both of the intercepts in the first equation are negative, so the line will form a triangle with the axes in the 3rd quadrant. The intercepts for the second equation are negative for y and positive for x, so the line forms a triangle with the axes in the 4th quadrant. The y-intercept for the first equation is -4.7; for the second equation, it is -40/7 = -5 5/7. This means the lines must cross in the 4th quadrant.

The only offered point in the 4th quadrant is (1, -5).

The graph shows a polynomial.The real zeros are x = -2, 3, 5.The least degree the polynomial can have is 3.

Step-by-step explanation:

There is nothing to indicate the graph is not of a polynomial function. Its zeros are the x=intercepts: -2, 3, 5. There are 3 of them, so that is the least degree the polynomial might have.

The graph shows a polynomial.The real zeros are x = -2, 3, 5.The least degree the polynomial can have is 3.

X is 70 degrees

Step-by-step explanation:

Answer:

X is 70 degrees

Step-by-step explanation:

all triangles and straight lines are up to 180 degrees so

180-120=60

we now have 2 angles, so now we need to subtract from 180 to get the missing number

180-60-50=70

What is the value of the expression below when w = 3. 4w^2 - 7w - 8

Answers

Answer: w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110 w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757

Step-by-step explanation:  The prime factorization of  4320   is

  2•2•2•2•2•3•3•3•5  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 4320   =  √ 2•2•2•2•2•3•3•3•5   =2•2•3•√ 30   =

               ±  12 • √ 30

 √ 30   , rounded to 4 decimal digits, is   5.4772

So now we are looking at:

          w  =  ( -40 ± 12 •  5.477 ) / -34

Two real solutions:

w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757

or:

w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

What equation do you get when you solve p = 2l + 2w for w

Answers

Answer:  When you solve for w the equation is [tex]w= \frac{p-2l}{2}[/tex]

Step-by-step explanation:

p = 2L + 2w  subtract 2L from both sides

p -2L = 2L -2L + 2w     2L-2L = 0 om the right; they cancel

p - 2L = 2w     now get w alone

(p - 2L)/2  = 2w/2   divide both sides by 2  2w/2 = w  2/2=1  it "cancels"

[tex]\frac{p +2L}{2} = w[/tex]  rewrite Reverse sides to put w alone on the left side

[tex]w= \frac{p-2l}{2}[/tex]

  B.  3x^2 +11x -20 = 0

Step-by-step explanation:

For solutions p and q, the quadratic will be

  (x -p)(x -q) = 0

We notice that the leading coefficients of the offered answer choices are greater than 1, so it will be convenient to use a value that "clears fractions."

  (x -4/3)(x -(-5)) = 0

  3(x -4/3)(x +5) = 0 . . . . multiply by 3 to clear the fraction

  (3x -4)(x +5) = 0 . . . . . . clear the fraction

  3x(x +5) -4(x +5) = 0 . . use the distributive property

  3x^2 +15x -4x -20 = 0 . . . . use the distributive property again

  3x^2 +11x -20 = 0 . . . . collect terms

_____

The constant in the product of factors is the product of roots:

  (x -p)(x -q) = x^2 -(p+q)x +pq

Here, that would mean the constant would be (4/3)(-5) = -20/3.

If we compare the above quadratic to the standard form:

  ax^2 +bx +c = 0

we find that we can divide the standard form equation by 'a' to get ...

  pq = c/a

That is, c/a = -20/3, so we might start looking for an answer choice that has a leading coefficient of a=3 and a constant of c=-20.

find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below

Answers

Answer:

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

Step-by-step explanation:

The equation of a linear function in slope-intercept form is: y = mx + b, where, m = slope, and b = y-intercept.

Find slope (m) of the linear function by using any two points, say (3, 11) and (7, 23):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 11}{7 - 3} = \frac{12}{4} = 3 [/tex]

To find the y-intercept (b), substitute the value of the corrdinate pair of any of the points represented on the table, and the value of the slope (m) into [tex] y = mx + b [/tex].

Substituting, x = -1, y = -1, m = 3.

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

[tex] -1 = 3(-1) + b [/tex]

[tex] -1 = -3 + b [/tex]

Add 3 to both sides

[tex] -1 + 3 = b [/tex]

[tex] 2 = b [/tex]

[tex] b = 2 [/tex]

Substitute m = 3, and b = 2 into the equation of the linear function in slope-intercept form:

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

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