Victoria is 4 years older than her neighbor. the sum of their ages is no more than 14 years.enter an inequality that can be used

elena55 [62]

V is 4 more tha x
v=4+x
sum is no more than 14
v+x≤14

sub 4+x for v
4+x+x≤14
4+2x≤14
minus 4 both sides
2x≤10
divide both sides by 2
x≤5
5+4=9

the neighboor's age is at most, 5 years
and victoria is 9 at most

What is the y-intercept of the line perpendicular to the line...

Dominik [7]

Answer:

D) 5

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes.

The line: $y=\frac{3}{4} x+3$ has a slope of $\frac{3}{4}$ as it is in y=mx+b form, where m is the slope, and b is the y-intercept.

Since the slope is $\frac{3}{4}$ , we see that the negative reciprocal slope is $-\frac{4}{3}$ , as $\frac{4}{3}$ is the reciprocal (flip the numerator and denominator).

From here, we can use point slope form: $y - y1 = m(x- x1)$ , where $(y1, x1)$ is the point. In this case, (3, 1) is the point.

Thus, we have: $y-1 =-\frac{4}{3}(x-3)$ as our final equation.

Simplifying: $y-1 = -\frac{4}{3}x+4$

And: $y=-\frac{4}{3}x+5$ , which gives us the y-intercept to be 5.

Let me know if this helps!

A, B, and C are midpoints of ∆XYZ. What is the length of cy

iogann1982 [59]

Answer:

$XY=36\ units$

Step-by-step explanation:

The correct question is

A, B, and C are midpoints of ∆XYZ. What is the length of XY

we know that

The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

step 1

Find the length of YZ

$AB=\frac{1}{2}YZ$
