Which ordered pair represents the y-intercept of the graph of the equation y = –4x – 7?

Dovator [93]

If <span>y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:

</span><span>0 = –4x – 7 => 4x = -7, or x = -7/4 The x-intercept is (-7/4, 0).

</span><span>The y-intercept is found by setting x = 0 and reading off the value of y:

y = –4x – 7 => y = 0 - 7, or y = -7. The y-intercept is (0, -7).</span>

AFLATI 2 NUMERE STIIND CA AL DOILEA NUMAR ESTE DE 7 ORI MAI MARE DECITPRIMUL IAR SUMA DINTRE DUBLUL PRIMULUI NUMAR SI TRIPLUL CE

postnew [5]

Answer:

The numbers are 20 and 140

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find 2 numbers knowing that the second number is 7 times greater than the first, and the sum between the double of the first number and the triple of the second is 460

Define the variables

Let

x ----> the first number

y ----> the second number

we know that

$y=7x$ -----> equation A

$2x+3y=460$ ----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B

$2x+3(7x)=460$

solve for x

$2x+21x=460$

$23x=460$

$x=20$

<em>Find the value of y</em>

$y=7x$ ----> $y=7(20)=140$

The numbers are 20 and 140
