Write a linear function f with the values f(0)=-1 and f(2)=-5

Darya [45]

Answer:

f(x) = - 2x - 1

Step-by-step explanation:

Let the linear function f(x) is given by f(x) = ax + b where a and b are unknown constants.

Given that f(0) = -1 and f(2) = -5

Hence, a(0) + b = - 1, ⇒ b = - 1

Again from the condition given

a(2) + b = -5, ⇒ 2a - 1 = - 5, ⇒ 2a = - 4, ⇒ a = - 2.

Therefore, the linear function is f(x) = - 2x - 1 (Answer)

How do i solve this problem?<br> Y=100+50x

gogolik [260]

Answer:

Step-by-step explanation:

to solve this you would subtract 100 from each side :

Y = 100+50x

-100 -100

-100= 50x

then you would divide each side by 50 to get 'x'

-100/50=50x/50

-2 = x

If the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola, find an equation for the parabola. Write

STALIN [3.7K]

Answer:

$y=-1(x-2)^2+3$

Step-by-step explanation:

W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form $y=(x-h)^2+k$ .

We know that vertex form of parabola in form $y=a(x-h)^2+k$ , where (h,k) in vertex of parabola.

Upon substituting coordinates of vertex, we will get:

$y=a(x-2)^2+3$

To find the value of a, we will substitute coordinates of point (0, -1) as:

$-1=a(0-2)^2+3$

$-1=a(4)+3$

$-1=4a+3$

$-1-3=4a+3-3$

$-4=4a$

$\frac{-4}{4}=\frac{4a}{4}$

$-1=a$

Therefore, our required equation would be $y=-1(x-2)^2+3$ .

The figure shows part of a freeway interchange. The raised freeway is supported by vertical, parallel pillars. Set up a ratio an

Ugo [173]

We will use ratio and proportion between the inclined sides with its corresponding horizontal bases. Then we could determine for the value of segment AQ.

PA/SB = AQ/BR
32/30 = AQ/24
AQ = 25.6 yd

Since what is asked is segment PQ,
PQ = PA + AQ
PQ = 32 + 25.6
PQ = 57.6 yards
