Answer:
its a because 5 x 4 = 20, 5 x 6 = 30 and 5 x 9 = 45
Step-by-step explanation:
THE ANSWER IS A
hope it helps ;)
4y square + y - 45 when y=-5
Given:
The expression is
[tex]4y^2+y-45[/tex]
To find:
The value of the given expression when y=-5.
Solution:
We have,
[tex]4y^2+y-45[/tex]
Putting y=-5, we get
[tex]4(-5)^2+(-5)-45[/tex]
[tex]=4(25)-5-45[/tex]
[tex]=100-50[/tex]
[tex]=50[/tex]
Therefore, the value of the given expression is 50 when y=-5.

Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Answer:
55 = 5x
Step-by-step explanation:
Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Equation to model this situation in the form y = mx + b,
y = Total number of stickers she had
x = Number of days that she gave away sticker
b = Fixed value = 0
Hence:
55 = 5x + b
b = Fixed value = 0
Therefore, the situation is represented as:
55 = 5x

The measure, in degrees of an angle that represents 50/360 of a circle is 50 degrees.
What is a circle?A circle is a locus of a point that moves in a plane such that its distance from a fixed point is always constant.
As we know that a circle has a total of 360 degrees all the way around the center.
So, the measure, in degrees of an angle that represents 50/360 of a circle will be = 50/360 * 360 degrees.
the measure, in degrees of an angle that represents 50/360 of a circle will be = 50 degrees.
Therefore, the measure, in degrees of an angle that represents 50/360 of a circle is 50 degrees.

The measure of the angle at the centre of the circle that represents 50/360 of a circle is 50°.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
A complete circle has a 360° angle at the center of it, since the angle we need to calculate is represented by 50/360, therefore, the measure of the angle can be written as,
[tex]\theta = \dfrac{50}{360}\times 360^o = 50^o[/tex]
thus, the measure of the angle at the centre of the circle that represents 50/360 of a circle is 50°.

i dont know functions
Answer:
6, -8
Step-by-step explanation:
You need to find out the possible values of which X cannot equal
In fractions the only way that's possible is if the denominator= 0
Because everything in the denominator is being mulitplied this is pretty simple
We need either parantheses to equal 0
so we take them and solve for 0
we have
x-6= 0
x=6
x+8=0
x= -8

Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
