Answer:

x-intercept= -6 & y-intercept = 8

Step-by-step explanation:

To find the intercepts you just have to put the opposite value as 0 in the equation.

X-intercept:

-4x + 3(0) = 24

Y-intercept:

-4(0) + 3y = 24

Everything times 0 is 0, so it cancels out.

Then it is just simple dividing.

Future reminder:

Just remember this (x,y)

-X-intercept point (?,0)

-Y-intercept point (0,?)

? = any number

Y -int. 8

x -int. -6

basically you just take the number beside x or y and divide it by the number that is behind the equal sign.

Secant RM intersects secant RN at point R. Find the length of RQ. If necessary, round to the hundredths place.

QveST [7]

Answer:

3 Units

Step-by-step explanation:

Secant RM intersects secant RN at point R.

The secants intersects the circle at points P and Q respectively as seen in the diagram.

To determine the length of RQ, we use the Theorem of Intersecting Secants.

Applying this on the diagram, we have:

RP x RN=RQ X RM

4(4+5)=RQ(RQ+9)

Let the length of RQ=x

$4*9=x^2+9x\\36=x^2+9x\\x^2+9x-36=0\\x^2+12x-3x-36=0\\x(x+12)-3(x+12)=0\\(x+12)(x-3)=0\\x+12=0$ x-3=0\\x=-12 or x=3\\Since x cannot be negative$\\x=|RQ|=3$

Therefore, length of RQ=3 Units

Daniel has a beginning balance of $675 in his checking account. He writes two checks for $530 and $200. He has a deposit of $340

GenaCL600 [577]

$675.00 - $530.00 = $145.00
$145.00 - $200.00 = $55.00 negative balance, amount short.
$55.00 + 340.00 = $285.00 positive balance after deposit.
$285.00 - $29.00 = $256.00 new balance
Daniel has a new balance of $256.00

V=M/D

grigory [225]

D=M/V. You just multiply both sides by D to get DV=M, then divide V by both sides.

The population of two different cities are modeled by the equations shown below. The population (in thousands) is represented by

lesya [120]

Answer: years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.
