First what you want to do is get rid of the parenthesis by solving each expression: -7.9×6.2=-48.98
-4.5+8.2=-12.7
now just add them together: -48.98+(-12.7)=-61.68
So the answer to this expression is -61.68

How do I translate the product of h and 4 is subtracted from one-fifth of x is 35 to an equation?
kolezko [41]

So we know that the word 'product' means multiplication, and that means that h and 4 are being multiplied. Also, one-fifth of x is another way of saying that one-fifth is being multiplied with x. So then we can construct the equation:

\frac{1}{5} x-(4*h)=35

And we can then simplify this by taking out the multiplication sign:

\frac{1}{5}x-4h=35

And so since we do not know what x or h is equal to, this is as far as we can go.

What value of "p" will the pair of equations
Nikolay [14]

Answer:

9

Step-by-step explanation:

Slope is the same as coefficient of x

From the equation

3x+4y=12

Y=(-3/4)x+3

The slope for this eqn is -3/4

For this equation

Px+12y=30

12y=-p+30

Y= (-p/12)x +30/12

The slope is -p/12

To get p

-p/12=-3/4

P=9

Which statement is true regarding the graphed functions? A) f(4)=g(4) B) f(4)=g(-2) C) f(2)=g(-2) D) f(-2)=g(-2)
fomenos

Answer:

Option (D)

Step-by-step explanation:

If the two points (x_1,y_1) and (x_2,y_2) are lying of the line.

Slope of the line represented by the function 'f' = \frac{y_2-y_1}{x_2-x_1}

Two points are lying on the line are (-2, 4) and (0, -2).

Slope of the line passing through these points 'm' = \frac{4+2}{-2-0}

m = -3

Y-intercept of the line 'b' = -2 [From the graph]

Therefore, equation of the function will be,

f(x)  = (-3)x - 2

f(x) = -3x - 2

Similarly, for other function represented by the line in red,

Slope of the line passing through (-6, 0) and (0, 6) = \frac{6-0}{0+6}

m' = 1

Y-intercept of g(x) = 5 [From the graph]

Equation that represents the function g(x) = 1.x + 5

g(x) = x + 5

For g(x) = f(x)

-3x - 2 = x + 6

-3x - x = 2 + 6

-4x = 8

x = -2

Therefore, for x = -2 both the functions will have the value.

f(-2) = g(-2)

Option (D) will be the answer.
