Step-by-step explanation:
Y: -4,2,-4,-28
I think thats the answer i did my calculations how i know how to do it and that's what i get.
Answer:
8
2
-4
-28
Step-by-step explanation:
y = -6(-1) + 2
y = 6 + 2
y = 8
y = -6(0) + 2
y = 2
y = -6(1) + 2
y = -6 + 2
y = -4
y = -6(5) + 2
y = -30 + 2
y = -28
A group of 33 people attended a ball game. There were twice as many children as adults in the
group. Set up a system of equations that represents the numbers of adults and children who
attended the game and solve the system to find the number of adults and the number of children
who were in the group.
Answer: children = 22
Adult = 11
Step-by-step explanation:
Let the number of adult be a
Since there were twice as many children as adults in the
group, the children can be represented by : 2 × a = 2a
We are further told that the group of 33 people attended a ball game. This means that :
adult + children = 33
a + 2a = 33
3a = 33
a = 11
11 adults are in the group
Since 11 adults are in the group, the number of children will be:
= 33 - 11
= 22

Write an equation of the line passing through each of the following pairs of points. b (5, 7), (−6, −3)
Answer:
y = 10/11 x + 2.45
Step-by-step explanation:
Equation of the line
First find the gradient
formula = [tex]\frac{y2-y1}{x2-x1}[/tex]
= [tex]\frac{-3-7}{-6-5}[/tex]
=[tex]\frac{-10}{-11}[/tex]
= 10/11
m is the gradient
equation of a line
y- y1 = m(x-x1)
y-7 = 10/11 (x-5)
y-7 = [tex]\frac{10}{11}x[/tex] - [tex]\frac{50}{11}[/tex]
y = 10/11 x + 2.45
NB i rounded of -50/11 +7 = 2.4545..... to 2.45

Can someone help me with this right answer only and please explain it too
Answer:
g(6) = 71
f(11) = 62
Step-by-step explanation:
Let's solve g(6) first
Plug 6 into x
g(6) = 2(6)^2 - 1
g(6) = 2(36) - 1
g(6) = 72 - 1
g(6) = 71
Now let's solve f(11)
f(11) = 5(11) + 7
f(11) = 55 + 7
f(11) = 62
Thus, out answers are 71 and 62 respectively

Find the area of the triangle
Answer:
472.5 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 30 and h = 31.5 , thus
A = [tex]\frac{1}{2}[/tex] × 30 × 31.5 = 15 × 31.5 = 472.5 yd²
