Answer:

y=0.75x+5

Step-by-step explanation:

It would be this equation because you start at 5, which is the y-intercept, then you add 0.75 for every pound of apples. So on a graph you would start at 5 on the y-line then go up by 0.75

2x² + 4x + 4 + x² + 1 = 180

Tasya [4]

Step-by-step explanation:

$2 {x}^{2} + 4x + 4 + {x}^{2} + 1 = 180$

$3 {x}^{2} + 4x + 5 = 180$

${3x}^{2} + 25x - 21x - 175 = 0$

$x \times (3x + 25) - 7(3x + 25) = 0$

$(3x + 25) \times (x - 7) = 0$

$3x + 25 = 0 = x - 7 = 0$

$x = - \frac{25}{3} = x = 7$

$= x_{1} = - \frac{25}{3} . \: \: x_{2} = 7$

Enter the sum of numbers as a product of their GCF. 75 + 30 The sum of the numbers as a product of their GCF is

Oksanka [162]

Answer: 75+30 = 15 x 7

Step-by-step explanation:

The given expression is 75+30 (=105) which defines the sum of 75 and 30.

Prime factorization of 75 and 30 are as below:

75 = 5 x 5 x 3

30 = 5 x 3 x 2

GCD (75,30) = 5x 3 = 15 [Note: GCD = Greatest common divisor]

Consider 75+30 = (15 x 5) + (15 x 2) [75 = 15 x 5 and 30= 15 x 2]

= 15 (5+2) [taking 15 as common ]

= 15 x (7)

(=105)

So, 75+30 which is sum of the numbers and it is expressed as 15 x 7 which a product of their GCF.

Choose the point-slope form of the equation below that represents the line that passes through the point (−1, 6) and has a slope

IrinaVladis [17]

Answer:

The correct answer is option B.

Step-by-step explanation:

Two point form of the equation:

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}\times (x-x_1)$

$\frac{y_2-y_1}{x_2-x_1}=Slope=m$

$(y-y_1)=m\times (x-x_1)$

A line passing through the point (-1,6) with slope ,m = -3.

The equation of the line will be:

$y-6=(-3)(x-(-1))=(-3)(x+1)$

Hence, the correct answer is option B.
