Answer:

The slope is 4

Step-by-step explanation:

So the formula is y=mx+b. M is the slope and b would be your y intercept. So the slope is 4. (I just did this in class)

4 sqrt (32) + 6 sqrt (50)

4 sqrt (16*2) + 6 sqrt (2*25)

4 sqrt (16)*sqrt(2) + 6 sqrt (2)*sqrt(25)

4 *4*sqrt(2)+6sqrt(2)*5

16sqrt(2)+30sqrt(2)

Find the value of x. Please help

bekas [8.4K]

Answer:

86 degrees

Step-by-step explanation:

For triangle the sum of angles is equal to 180 degrees

so,

x+(x-35)+43=180

2x -35+43=180

2x = 180-43+35

2x = 172

x = 86

Show that 4(m + 7) + (m + 3)^2 = (m + 3)(m + 7) + 16

anygoal [31]

Step-by-step explanation:

$4(m+7)+(m+3)^2=(m+3)(m+7)+16\\\\L_S=4(m+7)+(m+3)^2\\\\\text{use the distributive property}:a(b+c)=ab+ac\\\text{and formula}:\ (a+b)^2=a^2+2ab+b^2\\\\L_S=(4)(m)+(4)(7)+m^2+2(m)(3)+3^2\\\\L_S=4m+28+m^2+6m+9\qquad\text{combine like terms}\\\\L_S=m^2+(4m+6m)+(28+9)\\\\L_S=m^2+10m+37$

$R_S=(m+3)(m+7)+16\\\\\text{use FOIL}:(a+b)(c+d)=ac+ad+bc+bd\\\\R_S=(m)(m)+(m)(7)+(3)(m)+(3)(7)+16\\\\R_S=m^2+7m+3m+21+16\qquad\text{combine like terms}\\\\R_S=m^2+(7m+3m)+(21+16)\\\\R_S=m^2+10m+37\\\\\boxed{L_S=R_S}$

How do we write equations in slop intercept form and how do we do this entire page?

Alla [95]

So,...
the slope intercept form is y = mx+b
the m is the slope, and the b is the coordinate that intercepts the y-axis

so to start you off, 4x - 9y = 2

4x - 9y = 2
-4x - 4y

-9y = -4y +2

divide both sides by -9

-9y = -4y + 2
-9 -9

y = 4/9 x - 2/9
