Is (-1,1) a solution to y=3x+4 and 4y-3x=-7

1 answer:

7 0

(-1,1) is a solution to y=3x+4 but is not a solution to 4y-3x=-7

4y-3x=-7
Plug in the points
4(1)-(3(-1)) =-7
4+3 does not equal -7

X^2+10x+19=0 complete the square PLEASE EXPLAIN

wlad13 [49]

Answer:

Step-by-step explanation

In the form ax^2+bx+c

a x c should equal two factors of b

However, in this equation

1 x 19 has no factors that = 10

so you must use the Quadratic Formula which is,

x = $\frac{-b+-\sqrt{b^2-4ac} }{2a}$

so the answer should be

x = $\frac{-10+-\sqrt{10^2-4(1)(19)} }{2(1)}$

x = $\frac{-10+-\sqrt{24} }{2}$

x = $\frac{-10+2\sqrt{6} }{2}$ and x = $\frac{-10-2\sqrt{6} }{2}$

How would the graph change if the b value in the equation is decreased but remains greater than 1? Check all that apply.

Harrizon [31]

Answer:

The graph will begin on a lower point on the y-axis.

The y-values will continue to increase as x increases.

How do you solve 7a- 17=4a+1

Dennis_Churaev [7]

Answer:

a = 6

Explanation:

7a − 17 = 4a + 1

Subtract 4a from both sides

7a − 17 − 4a = 4a + 1 − 4a

3a − 17 = 1

Add 17 to both sides

3a − 17 + 17 = 1 + 17

3a = 18

Divide both sides by 3

3a / 3 = 18 / 3

a = 6

Encuentra la pendiente de la recta formada por los puntos A( 3 , -2 ) Y B( -5 , 3 )

QveST [7]

Answer:

$\frac{5}{-8}$ or -0.625

Step-by-step explanation:

The slope formula is as shown:

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1}}$

We can have A = ( $x_{1}$ , $y_{1}$ ) and B = ( $x_{2}$ , $y_{2}$ ).

We can hence plug in the values into the formula to get $m=\frac{3-(-2)}{-5-3}$ .

As we simplify, the negatives on the top row cancel out to give us an addition sign instead and we add them.

$m=\frac{5}{-8}$
