Answer:
f(x) = -²/₅ x - ¹⁷/₅Step-by-step explanation:
The equation of the linear function: f(x) = mx + b
f(-1) = -3 ⇒ -3 = m(-1) + b ⇒ m = b + 3
f(4)=-5 ⇒ -5 = m×4 + b
-5 = 4(b+3) + b
-5 = 4b + 12 + b
5b = -5 - 12
b = -¹⁷/₅
m = -¹⁷/₅ + 3 = -¹⁷/₅ + ¹⁵/₅ = -²/₅
Therefore the function:
f(x) = -²/₅ x - ¹⁷/₅last year there were b pies baked for the bake sale. This year there were 194 pies baked. Using b write an expression for the total number of pies baked in the two years
Answer:
b+194=pies
Step-by-step explanation:
take the number of pies baked this year then add the b and then you get p(pies)

how many solutions does y=-7x+8 y=-7x-8 have?
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = - 7x + 8 → (1)
y = - 7x - 8 → (2)
Substitute y = - 7x - 8 into (1)
- 7x - 8 = - 7x + 8 ( add 8 to both sides )
- 7x = - 7x + 16 (add 7x to both sides )
0 = 16 ← not possible
This indicates the system has no solutions
Hey there!
The answer to your question is [tex]no[/tex] [tex]solutions[/tex]
To solve this, we will set the equations equal to eachother. We know that since the two expressions, [tex]-7x+8[/tex] and [tex]-7x-8[/tex] both equal [tex]y[/tex], then the expressions are equal. (Somebody comment what property that is, I forgot what it's called) So:
[tex]-7x+8=-7x-8\\[/tex]
Add [tex]8[/tex] to both sides:
[tex]-7x+16=-7x[/tex]
Add [tex]7x[/tex] to both sides:
[tex]16 = 0[/tex]
Therefore, there are [tex]no[/tex] [tex]solutions[/tex].

m = -7 and it passes through the point (0,4)
Answer:
Y = -7x + 4
Step-by-step explanation:
Answer:
y=(-7)x+4
Step-by-step explanation:
y=m(x)+b
we know m so it is
y=(-7)x+b
the y intercept is 4 since the y intercept is when x=0
and we have our answer
y=(-7)x+4
sorry again but i'm having trouble on this one
Answer:
m∠PNO = 60°
m∠O = 33°
Step-by-step explanation:
∡NPO is 87° because it's a vertical angle with the 87° angle
3) ∡PNO is supplementary to the 120° angle (they must add to 180°)
4) m∠O = 180 - (60 + 87) = 33

Which of the following equations could you solve by first adding six and then dividing by negative three?
6 - 3 x = -9
+ 6 = -9
-3 x - 6 = -9
3 x - 6 = -9
Answer:
-3x - 6 = -9 (The third answer)
Step-by-step explanation:
When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.

El día 12 de diciembre en Moscú se registró una temperatura de 13° bajo cero, a esa misma hora, en buenos Aires hacía una temperatura de 25 grados sobre cero. ¿Qué diferencia térmica existía en ese momento entre las dos ciudades? A.38 B.-38 C.12 D.-12
Answer:
A. [tex]38\ \text{grados}[/tex]
Step-by-step explanation:
La temperatura en Moscú es de 13 grados bajo cero. Entonces, la temperatura es de -13 grados.
La temperatura en Buenos Aires es de 25 grados bajo cero. Entonces, la temperatura es de 25 grados.
La diferencia de temperatura entre las dos ciudades es
[tex]25-(-13)=38\ \text{grados}[/tex]

the cylinder has a height of 30cm and radius 11cm. work out the total surface area of cylinder
Answer:
total surface area=2832.66 cm^2
Step-by-step explanation:
11^2(3.14)x2=area of ends=760.26 cm^2
11x2x3.14=circumference=69.08 cm
69.08x30=area of side=2072.4 cm^2
2072.4+760.26=2832.66 cm^2
solve the inequality y - 8 > 13
Radius and diameter
How would I do this
Answer:
16
Step-by-step explanation:
The radius is half the diameter.
2×8=16cm
Answer:
[tex]16[/tex] cm
Step-by-step explanation:
The length of the diameter is simply twice, or two times as large as, the length of the radius. Therefore, if the length of the radius is [tex]8[/tex] cm, then the length of the diameter will be [tex]8*2=16[/tex] cm. Hope this helps!

If m<1=(6x+25), and m<2=(x+5), find m<2
Answer:
Assuming they are equal to each other, X = -4
Step-by-step explanation:
6x + 25 = x + 5
Subtract 5 from both sides
6x + 20 = x
subtract 6x from the left side
20= 5x
divide by 5

Harry is trying to complete his hill walking scouts badge. He is using a map with a scale of 1cm :2km.Harry has completed 4cm of the route on his map.How far has he actually walked?
Answer:
8km
Step-by-step explanation:
Given data
Scale is 1cm :2km
that is 1cm to represent 2km
hence
if 1cm represents 2km
the 4cm will be x
cross multiply
4*2= x
x= 8km
Hence he walked 8km

The ratio of tagged fish to untagged fish was 2 to 9. Ninety fish were tagged. How many fish were untagged
Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405
