Answer:

Yes

Step-by-step explanation:

(8,8) is a solution is y=x.

If we substitute the point into the equation, the equation is true.

(8,8) is in (x,y) format

Substitute:

y=x

8=8

LS=RS (left side equal rights side)

Answer:

yes

Step-by-step explanation:

y=x is just a linear function and the slope is 1 to 1.

so the y-intercept is 0 and the the line goes (1,1),(2,2),(3,3),(4,4).....etc so as x increases by 1, y increases by 1 and if it

makes it easier look at this:

y=1x+0

now look at this:

y=x

aren't they the same?

Hope that helps.

A certain gecko measured 3.5 inches as a hatchling, and then grows at a steady rate of 1.2 inches per month for the first 12 mon
gregori [183]

Answer:

21.1 inches

Step-by-step explanation:

The gecko is 3.5 inches to start with.

If it grows at a rate of 1.2 inches per month for the first 12 months, after 12 months the gecko will be 14.4 inches larger. (Because 12 times 1.2 is 14.4)

So, after 12 months the gecko will be 17.9 inches.

Since the gecko grows at 0.4 inches per month for the next 16 months, and the gecko has grown for 20 months, all we need to do is subtract 12 from 20 (since we already calculated how long it will be after 12 months) and multiply that by 0.4.

Since 20 - 12 is 8, we just multiply 8 by 0.4 to get 3.2. We now add 3.2 to 17.9 to get 21.1 inches.

Hope this helps!

An engineering school reports that 59% of its students are male (M), 39% of its students are between the ages of 18 and 20 (A),
KIM [24]

Answer:

.26

Step-by-step explanation:

.59 = M

.39 = A

.24= M∩A

M'∩A'= ?

M'∩A'= (M∪A)' (we call this demorgan's law)

MUA= M+A-M∩A

.59+.39-.24= .74

1-.74= .26

Is the following statement true or false? AB and AC intersect. ​
kakasveta [241]

True

Because you would first need to find the calculus of 3 and then divide 4 and

crossover it to 5 by the power of 20. Then you would need to get

measurements of angle AC which is 145* and then find the square root of 160.

Once that is done find angle  AB (172*) and add it to -pix. After that add it all

up and find the quotient. Then multiply it by infinite. So it is true

I hope this helps

What is the first step in solving the quadratic equation -5x^2+8=133?
bezimeni [28]

Answer:

a) subtracting '8' on both sides, we get

                                      - 5 x² + 8-8 = 133-8

                                        - 5 x²  = 125

b) The solution is x = 5 i

Step-by-step explanation:

<em>Explanation</em>:-

<u><em>Step (i):</em></u>-

Given quadratic equation  - 5 x² + 8 = 133

subtracting '8' on both sides, we get

                                      - 5 x² + 8-8 = 133-8

                                       - 5 x²  = 125

<u><em>Step(ii)</em></u>:-

dividing '-5' on both sides, we get

          \frac{-5 x^2}{-5} = \frac{125}{-5}

            x²  = -25

            x = \sqrt{-25}

            x = 5 i

A sporting goods store is having a 40% off sale. What would be the sale price for a pair of skis that originally cost $108.
Rzqust [24]

Answer:

$64.80

Step-by-step explanation:

Instead of saying 40% off, I look at is as paying 60% on.  (100% less 40%). So I’m going to pay 60% of the original price of $108.  

60% of $108 is $64.80
