Answer:
a = - 6, b = 13
Step-by-step explanation:
Given f(1) = 7 , that is f(x) = 7 when x = 1
f(3) = - 5 , that is f(x) = - 5 when x = 3
Substitute these values into f(x) = ax + b
a + b = 7 → (1)
3a + b = - 5 → (2)
Subtract (1) from (2) term by term to eliminate b
(3a - a) + (b - b) = - 5 - 7
2a = - 12 ( divide both sides by 2 )
a = - 6
Substitute a = - 6 into either of the 2 equations and solve for b
Substituting into (1)
- 6 + b = 7 ( add 6 to both sides )
b = 13

Answer:
f(x) = 3x + 1
Step-by-step explanation:
f(x) = 3x + 1
f(1) = 3+1 = 4
f(2) = 3*2 + 1 = 7
f(3) = 3*3 + 1 = 10
f(4) = 3*4 + 1 = 13
it's a linear function with slope 3 and y intercept 1

Answer:
80 degrees
Step-by-step explanation:
angle c=50
this is an isoceles triangle in which both base angles are same
so, angle e=50
now we will use angle sum.property which states that the sum of all the interior angles of a triangle is equal to 180
so, 50+50+angle d=180
100 + angle d = 180
angle d =180-100
angle d = 80 degrees

Answer:
Yes, Nan pays $25 more
Step-by-step explanation:
144 hours /24 hours per day = 6 days exactly
$50 + (5 x $25) = $175
145 hours 24 hours per day = 6 days and one hour (must pay for 7 days)
$50 + (6 x $25) = $200
$200 - $175 = $25 more
how do I solve this?
Answer:
v = 22
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{BI}{MO}[/tex] = [tex]\frac{BG}{MP}[/tex] , substitute values
[tex]\frac{v}{33}[/tex] = [tex]\frac{64}{96}[/tex] ( cross- multiply )
96v = 2112 ( divide both sides by 96 )
v = 22
Yasmin arived home from play practice began 20 minutes after the final bell and lasted for a half hour. When did school end.
Answer:
the school ended at 3:20pm
Step-by-step explanation:
Since Yasmin arrived home from play practice at 4:25 p.m.
The walk home took 15 minutes.
And, The practice starts 20 minutes after the final bell and lasted for a half hour.
Now Total time taken in all activities would be
= 15 + 20 + 30
= 65 minutes
Now deduct 1 hour and 5 minutes from 4:25 pm
i.e.
1 hour prior to 4:25 pm i.e. 3:25 pm
And, 5 minutes prior 3:25 pm i.e. 3:20 pm
So, the school ended at 3:20pm

Someone :) is there anyone know what is the answer?
Answer:
answers are below
Step-by-step explanation:
a. -6 ≤ 3x < 15
steps in order to solve:
-6 ≤ 3x
= -6/3 ≤ 3x/3
= -2 ≤ x
3x < 15
= 3x/3 < 15/3
= x < 5
=> -2 ≤ x < 5
b. -3 < 2x - 1 < 7
steps in order to solve:
-3 < 2x - 1
= 1 - 3 < 2x - 1 + 1
= -2 < 2x
= -2/2 < 2x / 2
= -1 < x
2x - 1 < 7
= 2x - 1 + 1 < 7 + 1
= 2x < 8
= 2x/2 < 8/2
= x < 4
=> -1 < x < 4
c. 7 < -3n + 1 ≤ 13

= -2 > n
-3n + 1 ≤ 13

what is the probability of rolling a standard die twice and getting an even number, then 5?
Answer: 22.222% or .2222
Step-by-step explanation:
There are 6 sides on a standard die. Two of the numbers (1&4) are perfect squares so the chances of getting a perfect square on the first roll is 2/6. There are 4 numbers less than 5 (1,2,3,4). The chances of rolling a number less than 5 on the second roll is 4/6. The probability of two events is equal to the product of those events or in this case 2/6 x 4/6 which is 8/36. Which reduces to 2/9. That’s 22.222% or .2222

The only solutions for a+b=5 and ab =4 is:
4 and 1 but we don't know which is which. In this case it doesn't matter though.
a² + b² = 16 + 1 = 17
