Ally has 4 times as many pencils as Anna Claire. They have 30 pencils in all. How many pencils does Ally have?
dexar [7]

T = 30

A = 4c

A + c = T

Anna Claire has 6 pencils. Times 4 makes Ally's pencil count. 4 * 6 = 24

24 + 6 = 30. So, you answer is: Ally has 24 pencils.

write an equation of the line that's passes through the point (1,6) and is parallel to the line whose equation is y= 3x - 5
Alex Ar [27]
Parallel lines have the same slope.
so to find any line, you need a set of points, and a slope.
we already have the slope, being 3.
so, use the equation
y- (y-point)/ x-(x-point)=slope.
y-6. 3
---- = ---- (make it a fraction by puttingitover 1)
x-1. 1
cross multiply.
1(y-6)=3 (x-1)
y-6=3x-3
add 6 to both sides
Final answer: Y=3x+3

Find the missing value when given the modulus. <br><br> |48+bi|=50
xxMikexx [17]

Answer:

missing value b is 14

Step-by-step explanation:

We have been given the modulus of a complex number which is

r=\sqrt{a^2+b^2}

Here on comparing the given complex number with general a+bi we get:

a=48 and b=b

On substituting the values in the formula for modulus we get:

\sqrt{48^2+b^2}=50

\Rightarrow 2304+b^2=50^2

\Rightarrow b^2=2500-2304

\Rightarrow b^2=196

\Rightarrow b=\sqrt{196}

\Rightarrow b=14

Therefore, missing value b is 14

In the equation, 7x^2 + 14xy = 7x (x + 2y), what is the binomial factor ?
KonstantinChe [14]

(x+2y)

How?

\\ \rm\longmapsto 7x(x+2y)

Use distributive law

  • a(b+c)=ab+bc

\\ \rm\longmapsto 7x(x)+7x(2y)

\\ \rm\longmapsto 7x^2+14xy
