The x intercept of the given line is (10, 0)

<h3>Finding the x intercept of a line</h3>

The x intercept of a line is the point where the line crosses the x-axis

It is the point where the value of y is zero

Given the equation of a line -2x+5y = -20

Substitute y = 0 into the equation

-2x +5(0) = -20

-2x = -20

x = 10

Hence the x intercept of the given line is (10, 0)

Find the value of x 85 (X + 37) (6x + 22) 69

g100num [7]

Answer:

x = 21°

The angles of the quadrilateral are:

85°
58°
148°
69°

Step-by-step explaination:

The above figure is a quadrilateral.

Hence, the angle sum of the shape is 360°.

Therefore,

$85 + (x + 37) +69 + (6x + 22) = 360$

$85 + x + 37 + 69 + 6x + 22 = 360$

$(85 + 37 + 69 + 22) + (x + 6x) = 360$

$213 + 7x = 360$

$7x = 360 - 213$

$7x = 147$

$x = \frac{147}{7}$

$x = 21$

The graph of which function is decreasing over the interval (–4, ∞)?

Phoenix [80]

Step-by-step explanation:

ok, logic

all of them are parabolas

1st and 3rd are opening up, so they defenitely increase, so no

decraseing

the vertex hs to be be at x=-4

y=a(x-h)^2+k

h has to be -4

y=a(x+4)^2+k

the answer is 2nd one or f(x)=-(x+4)^2+4

Pete, Chris, and Dina realized that the number of A’s they each received on their report cards were in a ratio of 4:2:5. If Pete

Fiesta28 [93]

Answer:

A's received by Dina is 35.

Step-by-step explanation:

Given

number of A’s received by Pete, Chris, and Dina on their report cards were in a ratio of 4:2:5.

Let the

A's received by Pete = 4x

A's received by Chris = 2x

A's received by Dina = 5x

This, is done so that ratio of 4:2:5 remains intact.

Now, given Pete got 14 more A’s than Chris got

Thus, writing it mathematically

A's got by Pete = A's got be Chris + 14

we will be using A's got Pete and Chris in term of x as defined above

4x = 2x+ 14

=> 4x - 2x = 14

=> 2x = 14

=> x = 14/2 = 7

A's received by Dina = 5x = 5*7 = 35( Answer).
