Answer:
She pays $1060 for the phone.
Step-by-step explanation:
Deposit = $100
She pays $80 each month for a year. $80 x 12 = $960. Then we need to add the deposit with the monthly instalments to find the total. $100 + $960 = $1060
Total:
$1060

34 you do 17×2 and get what you multiplily that by 0 .5
Step-by-step explanation:
66. Δy = -3.4 Δx
Δy/Δx = -3.4
The slope of the line is -3.4. Slope-intercept equation of the line is:
y = -3.4x + b
Plug in the given point to find b:
2 = -3.4(4) + b
b = 15.6
Therefore, the equation is y = -3.4x + 15.6.
Use the equation to find the y coordinates.

68. Repeat the same steps as 66.
Δy = -1.7 Δx
Δy/Δx = -1.7
The slope of the line is -1.7. Slope-intercept equation of the line is:
y = -1.7x + b
Plug in the given point to find b:
3 = -1.7(-7) + b
b = -8.9
Therefore, the equation is y = -1.7x − 8.9.
Use the equation to find the x or y coordinates.

Let's solve your equation step-by-step.
x2−6x+10=0
For this equation: a=1, b=-6, c=10
1x2+−6x+10=0
Step 1: Use quadratic formula with a=1, b=-6, c=10.

x = −(−6)± 
x= 6± 
x = 6±
