On Tuesday, Hayley only has 15 cups of flour and 9 eggs, but she has more than enough butter and sugar. Which system of linear i
BabaBlast [244]

<u>Missing part of the question</u>

Hayley bakes zucchini bread and banana bread. Some ingredients Hayley uses for each type of  bread are shown in the tables

Zucchini Bread

2 eggs        2 cups of flour       1.5 cups of sugar        0.5 stick of butter

Banana Bread

1 egg          3 cups of flour        2 cups of sugar          0.25 stick of butter

Answer:

2z + b \le 9

2z + 3b \le 15

Step-by-step explanation:

Given

Flour  = 15

Egg =9

Since there are enough of other ingredients, we will only consider the amount of eggs and cups of flour.

So, we have:

Zucchini Bread

Egg = 2

Flour = 2  

Banana Bread

Egg = 1

Flour = 3

<u>For the eggs</u>

The ratio of eggs to use in the Zucchini bread to Banana bread is:

Egg = 2 (z) : Egg = 1 (b)

This gives:

2z + 1b

The total number of eggs cannot exceed 9.

So, the inequality is:

2z + 1b \le 9

2z + b \le 9

<u>For the flours</u>

The ratio of flours to use in the Zucchini bread to Banana bread is:

Flour = 2 (z) :    Flour = 3 (b)

This gives:

2z + 3b

The total cups of flours cannot exceed 15.

So, the inequality is:

2z + 3b \le 15

Hence:

The system of inequalities is:

2z + b \le 9

2z + 3b \le 15

InWrite the equation of the line that passes through (7, - 4) and (- 1, 2) slope- intercept form.
blondinia [14]

Answer:

General Equation of a Line

General Equation \\(y - y_{1} )= m (x-x_{1}) \\Slope=m= \frac{x_{2}-x_{1} }{y_{2}-y_{1} } \\\\Given:\\p_{1}=(7,-4)\\p_{2}=(-1,2)\\Solution:\\m=(\frac{-1-7}{2-(-4)}) =\frac{-8}{6}\\y-(-4) = (\frac{-8}{6} )(x-7)\\y+4=\frac{-8x}{6} + 56\\y=\frac{-8x}{6} + 52 \\\\The\\  equation \\ is \\ y=\frac{-8x}{6} + 52

Step-by-step explanation:

Find the slope first and then place the values on the general formula. The final step is to solve for y

Need help i don't know what im doing?​
AveGali [126]

Answer:

X=5

Step-by-step explanation:

f(1)= -1^2+4(1)+12=15

f(2)= -2^2+4(2)+12=16

f(3)= -3^2+4(3)+12=15

f(4)= -4^2+4(4)+12=12

f(5)= -5^2+4(5)+12=7

g(1)=1+2=3

g(2)=2+2=4

g(3)=3+2=5

g(4)=4+2=6

g(5)=5+2=7

so g(5)=f(5)= X=5
