answer pls​

Answer:

m = - 1

Step-by-step explanation:

9m + 13 = 4

subtract 13 from both sides

9m = 4 - 13

9m = - 9

divide both sides by 9

m = - 1  (negative 1)

Step-by-step explanation:

just look at the graph and check the typical "special" points.

e.g. when x = 0, and when y = 0, and maybe (depending on the curve) some other interesting ones.

so, what does the graph tell for x = 0 ?

it says y = 5.

that rules out C and D, because they would deliver y = 1/5 for x = 0.

so, it can only be A or B.

now, what does the graph tell us for y = 0 ?

ok, it tells us, x = 1.

that does not help us in this case, as both, A and B deliver y = 0 for x = 1

so, let's look at another good point. good points are points, where we can see pretty precisely their coordinates on the chart, and where these coordinates are even integer numbers.

I see e.g.

x = 2, and y = -5

let's try A

-5 = -5 × cubic root(2 - 1) = -5 × cubic root (1) = -5×1 = -5

so, -5 = -5, that is correct.

let's verify by checking also B

-5 = 5 × cubic root (1 - 2) = 5 × cubic root (-1) = 5×-1 = -5

-5 = -5, again, this is correct.

hmmmmm.

when we think about it, in fact, A and B are the same function (by the way, C and D are equal to each other too).

either your teacher made a mistake or tried to trick you.

A and B are both the right answer.

why ?

A (I only write "cr" for cubic root now)

y = -5 × cr(x - 1) = 5 × -1 × cr(x - 1) = 5 × cr((-1)³(x - 1)) =

= 5 × cr(-1 × (x - 1)) = 5 × cr(x×-1 - 1×-1) = 5 × cr(1 - x) = B

so, A and B are actually equal.

Answer:

24

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

7² + altitude²  = 25²

      altitude²  = 25² - 7²

                       = 625 - 49

                       = 576

altitude = √576

altitude = 24

_________

[tex] \: [/tex]

b² = c² - a²

b² = 25² - 7²

b² = 625 - 49

b² = 576

b = √576

b = 24

The x and y intercept are (96,30)

Step-by-step explanation:

8y=240-2.5x

y=240/8-2.5x/8

y=30-0.3125x

The y intercept=30

The x intercept=96 thus 30=0.3125x,x=30/0.3125

Answer: A, C, D

Step-by-step explanation:

Replace x and y with the given values:

2/3(9-6) - 5/6

Simplify:

2/3(3) - 5/6

Multiply:

2 - 5/6

Subtract:

1 1/6

Answer 1 and 1/6

The required simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

To find the value, substitute the given values of x and y into the expression:

2/3(x - 6) - y

= 2/3(9 - 6) - 5/6

= 2/3(3) - 5/6

= 2 - 5/6

To subtract fractions, you need a common denominator:

= 12/6 - 5/6

= 7/6

Therefore, the simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

Answer:

the vertex is (0,3)

Step-by-step explanation:

using vertex form: y=a(x-h)^2+k    you can find the vertex

h: the horizontal <----------->

and

k: the vertical       |      

so, there is no h, but there is a k, which is 3, so the answer is (0,3) I believe

The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Let c represent the number of cookies and let b represent the number of brownies.

Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:

c + b ≥ 125   (1)

Also, Genie has a total of 2,000 grams of flour, hence:

8c + 12b ≤ 2000  (2)

Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Good luck on whatever you are doing.

Step-by-step explanation:

shape BCD is an isosceles triangle meaning the base angles will be the same.

CA is a straight line meaning that it is 180

the sum of angles in a triangle always is 180

so

180-36= 144

to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.

144/2= 72

x=72

the angle just below y is also 72.

as CA is a straight line,

180-72= 108 giving you the answer for y

y= 108

so to make the answer clear

x= 72

y= 108
