Find the slope and y-intercept for the graph of the equation.
9x + 4y = 8

Answers

Answer:

slope= - 9/4    yintercept 0,2

Step-by-step explanation:

Answer:

slope = - [tex]\frac{9}{4}[/tex] , y- intercept = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

9x + 4y = 8 ( subtract 9x from both sides )

4y = - 9x + 8 ( divide terms by 4 )

y = - [tex]\frac{9}{4}[/tex] x + 2 ← in slope- intercept form

with slope m = - [tex]\frac{9}{4}[/tex] and y- intercept c = 2

What is the input when f(x)=18?

Answers

Answer: The input is 5.

Step-by-step explanation: Since both are functions of f(x), you can set 9x-27 equal to 18 and then solve the equation. 9x-27=18, add 27 to both sides to get 9x=45, divide both sides by 9, x=5.

:)

Answer is 5


You replace the f(x) with 18 which makes it into (18)=9x-27 then you do basic algebra from there.

Evaluate the equation: a + 1.23 = 3.6

Answer:

3f

Step-by-step explanation:

f+f+f=3f

since every f has the same value

example

2+2+2=3(2)

6=6

Answer:

3f

Step-by-step explanation:

There are three f's added together, which makes 3f. If you had multiplied them all it would've been f^3, if you had divided f by 3 you would have f/3, and if f=1 it would've just been 3. This is why 3f is the best answer here.

Which statement best explains whether △JKL is congruent to △MNP?

Answers

Answer:

D.

Step-by-step explanation:

The triangles are congruent, and the correct answer is D.

D. △JKL is congruent to △MNP because △JKL can be mapped to △MNP by a rotation of 180° about the origin followed by a translation 2 units up.

Rotation of triangle JKL by [tex]180^{o}[/tex] will result in the triangle with corresponding vertices of (2, 4), (3, 2) and (-1, 2).

so translating the resulting triangle two units up will result in the triangle with corresponding vertices (4, -2), (2, -3) and (2, 1) which is the same triangle like the given triangle MNP.

Which best explains why the figures are congruent?

The figures is congruent because the 270° rotation about the origin or then the reflection over the x-axis would mapped ΔABC into ΔLMN.

325.623 rounded to nearest hundredth

Answers

Answer:

325.62

Step-by-step explanation:

Find the number in the hundredth place  2  and look one place to the right for the rounding digit  3. Round up if this number is greater than or equal to  5  and round down if it is less than  5 .

325.62

When your rounding you look at the number next to the number your rounding to. For example: 325.623 the hundredths place is the 2 so the number next to it is 3.

When your rounding there is a saying ( there r different ways of saying it this is the way I was taught) 5 or more raise the score. 4 or less let it rest. Meaning if it’s 5 or more raise the number one level up ( 5 goes to 6, 6 goes to 7, 7 goes to 8, 9 goes to 10). If it’s 4 or less take away the numbers behind the number your rounding to. ( Example: 45.6478 if we r rounding to the nearest tenth we look at the 4 it’s 4 or less so it would be 45.6).

So 3 is less than 4 so we take away the numbers behind the 2 therefore we get or answer 325.62

Hope I didn’t bore you and hope this helps. :)
