14x+4(7)=y (y=154) what is the value of x

Since y is 154, the equation is 14x + 4(7) = 154.

Next, you multiply 4 and 7 that equals to 28. The equation is now : 14x + 28 = 154.

Third, you going to cancel 28 and -28 because they both equal to zero ( 0 ). Now you do 154 minus 28. It’s equals to 126.

this is the new equation: 14x = 126.
you now going to divide 14 each under the numbers 14 divided by 14 is 1, so it’s canceled out. Now focus on 126 divided by 14, it’s equals to 9

The answer is x = 9.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
