Where do lines modeled by equations y=-7/8x+1/4 and y=-3/4x+1/2 intersect
vlabodo [156]
If they intersect they have the same x and y values so we can say y=y which can be expressed as:

-7x/8+1/4=-3x/4+1/2  make all terms have a common denominator of 8

-7x/8+2/8=-6x/8+4/8  now multiply all terms by 8

-7x+2=-6x+4  add 6x to both sides

-x+2=4  subtract 2 from both sides

-x=2  divide both sides by -1

x=-2, now we solve for y using either original equation...

y=-3(-2)/4+1/2

y=6/4+1/2

y=6/4+2/4

y=8/4

y=2  so the lines intersect at the point:

(-2, 2)

Let f (x)=x^2+2x-35 enter the x-intercepts of the quadratic function in the boxes __and___
serious [3.7K]

Answer:

The x-intercepts of the quadratic function are -7 and 5.

Step-by-step explanation:

The given function is

f(x)=x^2+2x-35

Equate f(x)=0, to find the x-intercepts of the function.

x^2+2x-35=0

x^2+7x-5x-35=0

x(x+7)-5(x+7)=0

(x+7)(x-5)=0

x+7=0\Rightarrow x=-7

x-5=0\Rightarrow x=5

Therefore the x-intercepts of the quadratic function are -7 and 5.

Two urns both contain green balls and red balls. Urn I contains 6 green balls and 4 red balls and Urn II contains 8 green balls
34kurt

Presumably, whatever is drawn from Urn I is independent of what is drawn from Urn II. This means

P(\text{red from Urn 1 AND red from Urn 2})=P(\text{red from Urn 1})\cdot P(\text{red from Urn 2})

We have

P(\text{red from Urn 1})=\dfrac4{10}=\dfrac25

P(\text{red from Urn 1})=\dfrac7{15}

so the probability of drawing red balls from both urns is \dfrac25\cdot\dfrac7{15}=\dfrac{14}{75}

The sum of the measures of the interior angles of a polygon with n sides is
defon

ANSWER

(n - 2) \times 180 \degree

EXPLANATION

The sum of the interior angles of a triangle is 180°

We can rewrite this as:

1 \times 180 \degree = (3 - 2) \times 180 \degree = 180 \degree

The sum of interior angles of a quadrilateral is 360°

We can also rewrite this as:

2 \times 180 \degree = (4- 2) \times 180 \degree = 360 \degreeIn general an n-sided polygon has

the sum of the interior angles given by the formula:

(n - 2) \times 180
