Answer:

hello your question have some missing part attached below is the missing part

answer : y ( intercept )  = 8

Step-by-step explanation:

Having three linear equations with y-intercepts of -3, 8 and 7,

To determine The y-intercept of this function ;

x = 0 and x = 0  which comes in   -2 ≤ x < 3

f' - f(x) = x + 8 ,

therefore the y intercept in  f(0) = 0 + 8 = 8

The time required for a skilled worker to produce x shirts is given by the function T(x) = 4x + 2, where T is measured in hours.
solong [7]

Answer:

A. $1,110

B. 50 units.

Step-by-step explanation:

A. Substitute x=18 into the function T(x)=4x+2 for calculate the time in hours required for the worker to produce 18 units:

T(18)=4(18)+2=74

Now you need to substitute T=74 into the function S(T)=15T to calculate the amount in dollars she will be paid for 74 hours:

S(74)=15(74)=1,110

She will be paid $1,110.

B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute S(T)=3,030 into the function S(T)=15T and solve for T (to find the number of hours she requires to work to be paid $3,030)

3,030=15T\\\\T=\frac{3,030}{15}\\\\T=202

Now, substitute T(x)=202 into T(x)=4x+2 and solve for x, to calculate the number of units she produces in 202 hours:

202=4x+2\\\\202-2=4x\\\\x=\frac{200}{4}\\\\x=50

She would need to produce 50 units to be paid $3,030

Firlakuza [10]
Domain is inputs, input the domain for x
y=5(-1.2)-2
y=-6-2
y=-8

y=5(0)-2
y=0-2
y=-2

y=5(4)-2
y=20-2
y=18

range is {-8, -2, 18}
