Find h(7) if h(x)=-7x-3

h(7) = -52

Step-by-step explanation:

To get our answer, we must first set up the equation by plugging the value of 7 into x.

h(7) = -7(7) - 3

Following the order of operations, we multiply the number inside the parentheses by the number outside of it first.

-7 × 7 = -49

That leaves us with h(7) = -49 - 3

Now we subtract what's left to find our answer.

-49 - 3 = -52

h(7) = -52

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
